ID’s deep roots in creationism


Fundamentalist folliesProponents of creationism often try to deny that “intelligent” design (ID) is merely creationism wrapped in a fake lab coat to make it look like it’s pals with science. It isn’t. They’re not buddies, didn’t go to school together, and don’t ‘like’ each others Facebook pages.

ID is merely a tawdry, paper-thin attempt to hoodwink the gullible who can’t see past the plastic pocket protector that there’s a bible in the pocket. In part this is because the popular notion of what a theory is has devolved into a synonym for guess or an unproven assumption. But that’s not the scientific meaning of the word: “…a well-confirmed type of explanation of nature, made in a way consistent with scientific method, and fulfilling the criteria required by modern science… Scientific theories are the most reliable, rigorous, and comprehensive form of scientific knowledge.” Scientific method

ID is not even a hypothesis: it’s a statement of faith and its pseudo-scientific arguments have been well-debunked on better sites than this (i.e. Skeptico). It starts with belief and looks for ways to prove it, rejecting anything that counters that preconceived theology.
creationism masquerading as ID

The National Center of Science Education defines ID this way:

“Intelligent Design” creationism (IDC) is a successor to the “creation science” movement, which dates back to the 1960s. The IDC movement began in the middle 1980s as an antievolution movement which could include young earth, old earth, and progressive creationists; theistic evolutionists, however, were not welcome. The movement increased in popularity in the 1990s with the publication of books by law professor Phillip Johnson and the founding in 1996 of the Center for the Renewal of Science and Culture (now the Center for Science and Culture.) The term “intelligent design” was adopted as a replacement for “creation science,” which was ruled to represent a particular religious belief in the Supreme Court case Edwards v. Aguillard in 1987.
IDC proponents usually avoid explicit references to God, attempting to present a veneer of secular scientific inquiry. IDC proponents introduced some new phrases into anti-evolution rhetoric, such as “irreducible complexity” (Michael Behe: Darwin’s Black Box, 1996) and “specified complexity” (William Dembski: The Design Inference, 1998), but the basic principles behind these phrases have long histories in creationist attacks on evolution. Underlying both of these concepts, and foundational to IDC itself, is an early 19th century British theological view, the “argument from design.”

Despite angry denials from creationist supporters that ID is not the same, and instead ID is a form of scientific research, that’s balderdash. It’s the “wedge” strategy- the ID movement’s published methods for inserting their religious content into the secular world.
Creationist bingo

All they’ve done is use cut-n-paste to replace terms like creationism in their documents with scientific-sounding phrases like “intelligent” design. They haven’t changed the core religious nature of their argument. Common Sense Atheism documents this as a clumsy, but failed attempt to mislead the reader:

…consider how the term “intelligent design” was born. In 1987, the Supreme Court ruled that “creation science” could not be taught in public schools because it advances a particular religion. That same year, a Creationist textbook called Of Pandas and People had been published using terms like “creationism” over 150 times. But after the defeat of Creationism in court, the editors replaced every instance of “creationism” with “intelligent design” and every instance of “creationists” with “design proponents.” In one case, part of the original term, “creationists,” was left behind by the editing process, rendering “cdesign proponentsists”… That the editors merely replaced “creationism” with the new term “intelligent design” is abundantly obvious when one compares various drafts of Of Pandas and People (originally called Biology and Creation)…

ID supporters universally identify the need for a “designer” as the mechanic behind the curtain, and all say it’s their own particular Christian deity. Wikipedia notes:

Intelligent design (ID) is a form of creationism promulgated by the Discovery Institute, a politically conservative think tank. The Institute defines it as the proposition that “certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection.” It is a contemporary adaptation of the traditional teleological argument for the existence of God, presented by its advocates as “an evidence-based scientific theory about life’s origins” rather than “a religious-based idea”. All the leading proponents of intelligent design are associated with the Discovery Institute and believe the designer to be the Christian deity.

A designer, logically, has to be a deity* but why only this particular one? I have yet to run across a single ID proponent who will say that designer is Shiva. Or Kali. Or Moloch. Or Ra. Or Odin. Or Zeus. Why not each one working as a team (because there’s no God in team)? All of the hundreds of other deities (thousands?) in world mythologies and religions are ignored and just one is elected as the only possible designer: the hairy thunderer of the New Testament. Not only are non-Christians excluded from ID, but so are Catholics. Only fundamentalist literalist Christians need apply.

Creationism poster

As Wikipedia also notes:

Scientific acceptance of Intelligent Design would require redefining science to allow supernatural explanations of observed phenomena, an approach its proponents describe as theistic realism or theistic science.

In other words, yes kids, Santa Claus really does put those presents under the Xmas trees of good children every year, millions of them simultaneously, all over the world, delivered from a sleigh that travels faster than light and, while seemingly small, actually has an infinite storage capacity. Never mind those wrapped boxes you found at the back of the closet last week. Those aren’t proof of another, more logical explanation of how the presents arrive. Belief is more important than observation, so don’t question our explanation. We’ll tell you what you need to know.
Creationist continuum
As noted in another article on the NSCE website:

Following creationist tradition, IDC proponents accept natural selection but deny that mutation and natural selection are adequate to explain the evolution of one kind to another, such as chordates from echinoderms or humans and chimps from a common ancestor. The emergence of major anatomical body types and the origin of life, to choose just two examples popular among IDC followers, are phenomena supposedly too complex to be explained naturally; thus, IDC demands that a role be left for the intelligent designer — God.

About.com sums it up very well:

Intelligent Design is, like all other creationist movements, more about politics and religion than about science. Where Intelligent Design differs is that it was originally and deliberately conceived in explicitly political terms whereas earlier creationist movements tended to acquire political goals and principles over time. This is very important to understand because it reveals as false the pretensions of Intelligent Design apologists that they are involved in a scientific enterprise.

The US judicial system recognized the similarity between the two, as well (see this article). Judge Jones noted in the Dover School case:

ID uses the same, or exceedingly similar arguments as were posited in support of creationism. One significant difference is that the words “God,” “creationism,” and “Genesis” have been systematically purged from ID explanations, and replaced by an unnamed “designer.”
Demonstrative charts introduced through Dr. [Barbara] Forrest show parallel arguments relating to the rejection of naturalism, evolution’s threat to culture and society, “abrupt appearance” implying divine creation, the exploitation of the same alleged gaps in the fossil record, the alleged inability of science to explain complex biological information like DNA, as well as the theme that proponents of each version of creationism merely aim to teach a scientific alternative to evolution to show its “strengths and weaknesses,” and to alert students to a supposed “controversy” in the scientific community. In addition, creationists made the same argument that the complexity of the bacterial flagellum supported creationism as Professors Behe and Minnich now make for ID.

ID cartoon
Talkreason.org has many good articles critiquing ID, but this one is particularly good because it deconstructs a description from the “Discovery Institute” (the political and religious organization that developed and promotes ID, and spreads the wedge):

Right away we are told that ID is a program conducted by “scientists, philosophers, and other scholars who seek evidence of design in nature.” Basically this is an admission that their program is not about gathering data and allowing the evidence to lead them wherever it may, but rather a mission to find evidence which supports a predetermined conclusion — that being that an intelligent agent created everything. In this way, the ID “researcher” confines himself to analysis of only those findings which he may have use for as a buttress for the conclusion he has already arrived at. It goes without saying that this is not science. To presuppose automatically the existence of a (perhaps supernatural) designer is to preclude real, thoughtful, scientific research in accordance with the scientific method, since science deals only with observable, measurable, phenomena.

You can’t research an act of god. Any god. What happens when you find something you can’t fully explain or understand? IDers would assign it to “the designer” then move on. Scientists would investigate further to try and provide an answer that doesn’t involve a supernatural cause. They would look to see what existing laws, theories or hypotheses are related and whether they apply. They would test, then retest, and test again until something made sense, long after IDers had shrugged their shoulders and given up looking.
ID trial arguments
ID is, like the notion of the flat earth, based not on observation, research and experimentation, but simply on blind faith.
Intelligent geography
Why would ID deserve any more research that, say, phrenology? ID has already decided the answer, so anything scientists find that explains outside that answer will be rejected by the IDers. They already start by rejecting science – evolution, cosmology, biology.
Common Sense Atheism does allow that creationism and ID are, semantically, different terms (although joined at the hip by their theological basis):

Here’s how I like to think of Creationism and Intelligent Design. I tend to use “Creationism” to refer to theories informed by the Bible or Christian (or Muslim) theology. For example, a theory including a 6,000 year old Earth is obviously Creationism.
In contrast, I tend to use “Intelligent Design” to refer to modern attempts at natural theology, which are not dependent on scripture or doctrine. The method of natural theology is to make an inference from observations of public, natural evidence to the existence of some kind of Designer or First Cause. This method does not allow you to assume any properties at all about the Designer that cannot be inferred from the observations of public, natural evidence… Remember, “intelligent design” and “creationism” are just words. They mean whatever we say they mean.

I agree, but I prefer to call it “ID creationism” so that the concept is not mis-identified by those who are not aware of the historical or political origins of the ID movement, and somehow mistakenly think that ID is actually something scientific.It isn’t. It’s claptrap masquerading as an “alternative” to science. Why should we pretend otherwise?

* Clearly the whole argument fails if you don’t believe in this or any other deity. If it wasn’t Ganesh who made the world and all the cute bunnies and squirrels, then I ain’t buying it… but you don’t have to be an atheist to believe in evolution: a modest education, and an open mind are all you need.

Evolution, Creationism, and Elections


Jesus and dinosarsEarlier this summer, Gallup released the results of its latest poll on American belief in evolution, creationism and “intelligent” design. The results are among the most depressing numbers ever posted about the decay of American thought and education. Yet although this should set off the warning bells to both US presidential candidates that something needs to be done to stem this problem, none of this has been raised in the debates or on the campaign trail.

How can this have happened in one of the most technologically advanced nations in the world? How is it that the only nation to put a man on the moon, a nation that can put a rover on Mars or a satellite into orbit around Saturn with pinpoint accuracy, has so many superstitious dunderheads?

American fundamentalism is becoming increasingly pronounced in the political process, and has interfered at many levels in the education system to force its beliefs into curricula. Surely some of the American policy makers recognize this disturbing trend, but none have, so far, addressed it.*

In the excellent TV drama, The Newsroom, Will McAvoy (played by Jeff Daniels) attacks the American fundamentalists in politics – the so-called Tea Party wing that has hijacked the Republican party – calling them the American Taliban. It’s easy to see the parallels between them – they both want a faith-based curricula, to punish non-believers in their particularly myopic faith, to merge that faith with the political process, and to repeal women’s rights and return them to a subservient role as chattel. McAvoy’s statement, made in the final episode of series one, is easily understood by anyone who has been watching recent US election campaigns.

The question about belief in evolution or other notions has been asked by Gallup since 1986 and the results have been fairly consistent. Gallup asked the following questions. The current and historical results are charted below.
Gallup poll on evolution vs superstition
Forty-six per cent of respondents believe in magic and myth rather than the copious scientific proof for evolution. That is nearly half of all Americans! That number has not dipped below 40% since Gallup started asking the question. A third of Americans (32%) believe humans evolved, but under their god’s guiding hand.

Gallup has asked Americans to choose among these three explanations for the origin and development of human beings 11 times since 1982. Although the percentages choosing each view have varied from survey to survey, the 46% who today choose the creationist explanation is virtually the same as the 45% average over that period — and very similar to the 44% who chose that explanation in 1982. The 32% who choose the “theistic evolution” view that humans evolved under God’s guidance is slightly below the 30-year average of 37%, while the 15% choosing the secular evolution view is slightly higher (12%).

The American belief in the science of evolution**, as a natural process independent of deities or magical intervention, has never risen above 16%. It’s at 15% today. Only one in seven Americans believe in one of the most important, most most heavily documented and evidenced laws of biology. So why isn’t this failure of education in the front lines of the presidential debate?

Some of this is the result of the unrelenting political and social campaigns and lobbying by the Christian right and its anti-science organizations to reinforce their fundamentalist grip on US politics. And they seem to have succeeded in getting may of their supporters into office.

The presidential candidates are likely too scared to confront this army of ignorant believers – especially Romney, whose Republicans make up the largest group of superstitious believers, as Gallup noted:

Majority of Republicans Are Creationists
Highly religious Americans are more likely to be Republican than those who are less religious, which helps explain the relationship between partisanship and beliefs about human origins. The major distinction is between Republicans and everyone else. While 58% of Republicans believe that God created humans in their present form within the last 10,000 years, 39% of independents and 41% of Democrats agree.

But Obama is equally silent on the issue to, maybe because the poll showed 41% of Democrats are equally superstitious and believe in creationism.

Yet both candidates (and see here) have admitted they believe in evolution, not creationism, and oppose teaching creationism in schools. So why don’t they say so on the campaign trail, especially in states that have brought this nonsense into schools?

No one, it seems, wants to confront the idiots who support creationism, and rub their noses in their ignorance. And by not doing so, politicians have allowed the fundamentalists to set the political agenda.

Madness. I’m not the only one concerned about how the religious right as hijacked the political debate – almost any topic from abortion to gay marriage to science to other faiths comes with a heavy doze of fundamentalist disapproval. As Katherine Stewart recently wrote,

The far right’s fixation on same-sex relationships is so ludicrous that it defines a sub-category of camp. But let’s take a step back for a moment. The big question, the one that keeps coming back in every one of these skirmishes in the culture wars, is: why is the loudest religion in American politics today so much about hate?

(A comment on the GOP’s religiously-fuelled policies over women’s rights and abortion can be found in a recent HuffPost blog by Ethan Rome.)

Can you imagine an elected politician who sits on the House Science, Space and Technology Committee making a statement that evolution is a lie “straight from the pit of hell”? But that comment came from Republican Rep. Paul Broun last month.

An ultraconservative congressman whose district includes the University of Georgia campus, Broun told a Baptist church last month that evolution, embryology and the Big Bang theory were lies spread by scientists out to erode people’s faith in Jesus Christ. He also claimed the Earth is roughly 9,000 years, a view held by fundamentalist Christians based on biblical accounts of creation.

Here are his actual words:

“God’s word is true. I’ve come to understand that. All that stuff I was taught about evolution, embryology, Big Bang theory, all that is lies straight from the pit of hell. It’s lies to try to keep me and all the folks who are taught that from understanding that they need a savior. There’s a lot of scientific data that I found out as a scientist that actually show that this is really a young Earth. I believe that the Earth is about 9,000 years old. I believe that it was created in six days as we know them. That’s what the Bible says. And what I’ve come to learn is that it’s the manufacturer’s handbook, is what I call it. It teaches us how to run our lives individually. How to run our families, how to run our churches. But it teaches us how to run all our public policy and everything in society. And that’s the reason, as your congressman, I hold the Holy Bible as being the major directions to me of how I vote in Washington, D.C., and I’ll continue to do that.”

Another recent member of that committee was Missouri Rep. Todd Akin, who claimed victims of “legitimate rape” were unlikely to become pregnant because “the female body has ways to try to shut that whole thing down.”

That, in a nutshell, is what is wrong with American politics in 2012: the religious right. It’s also what is particularly wrong with the Republican Party. And for the life of me, I can’t find anything to disprove Will McAvoy’s statement.

Let me close with a few quotes from this American Taliban:
“The long-term goal of Christians in politics should be to gain exclusive control over the franchise. Those who refuse to submit publicly to the eternal sanctions of God by submitting to His Church’s public marks of the covenant–baptism and holy communion–must be denied citizenship.”
“This is God’s world, not Satan’s. Christians are the lawful heirs, not non-Christians.”
Gary North (Institute for Christian Economics)
“When the Christian majority takes over this country, there will be no satanic churches, no more free distribution of pornography, no more talk of rights for homosexuals. After the Christian majority takes control, pluralism will be seen as immoral and evil and the state will not permit anybody the right to practice evil.”
Gary Potter (Catholics for Christian Political Action)
“I don’t know that atheists should be considered citizens, nor should they be considered patriots. This is one nation under God.”
George Bush Sr. (former President of the United States)
“The Christian community has a golden opportunity to train an army of dedicated teachers who can invade the public school classrooms and use them to influence the nation for Christ.”
James Kennedy (Center for Reclaiming America)
“Evolution is a bankrupt speculative philosophy, not a scientific fact. Only a spiritually bankrupt society could ever believe it…Only atheists could accept this Satanic theory.”
Jimmy Swaggart (Jimmy Swaggart Ministries)
“Nobody has the right to worship on this planet any other God than Jehovah. And therefore the state does not have the responsibility to defend anybody’s pseudo-right to worship an idol.”
Joseph Morecraft (Chalcedon Presbyterian Church)
“I’m an old-fashioned woman. Men should take care of women, and if men were taking care of women today, we wouldn’t have to vote.”
Kay O’Connor (Kansas Senate Republican)
“Anybody that believes in separation of church and state needs to leave right now.”
Star Parker (Coalition on Urban Renewal & Education)

* In Canada, when PC-then-Alliance-politician-then-Conservative cabinet minister, Stockwell Day, was exposed as a “young-earth” creationist in national media, he was widely ridiculed and criticized for for holding both a top political job and erroneous ideologies. In 2008, an Angus Reid poll showed  “58 percent (of Canadians) accept evolution, while 22 percent think that God created humans in their present form within the last 10,000 years.” That’s better than the US, but still way too high.

** Without evolution, almost everything we know and understand about biology fails. It would be like astronomy without believing in the speed of light – which is exactly what creationism is, because without the time required by Darwinian evolution, the distant galaxies can’t be millions of light years away. Cosmology fails without evolution because it means everything we have learned or posited about the development of stars and planets is false.

CreationistsThe law of entropy, which governs all physics – the second law of thermodynamics – is repealed under creationism. We need a new model to teach us how energy behaves. If creationism is correct, then the entropic effects we have measured in stars and galaxies can’t have happened, since they require millions, even billions of years to occur. Einstein’s relativity, too, goes out the window.

Creationism means humans and Mesozoic dinosaurs co-existed. Humans and Permian dimetrodons co-existed, too. Paleozoic trilobites crawled in the shallow water while humans walked the shore, although no fossil record of them exists after the great Permian extinction. The sea giants megalodon, the giant shark, swam in the oceans with reptilian plesiosaurs, mosasaurs, pliosaurs and the giant armoured fishes of the Devonian, the placoderms.

Woolly mammoths preserved in the Siberian ice during an Ice Age that must not have happened, walked the earth while pterosaurs (extinct 65 million years ago) sailed in the skies above them and Tyrannosaurs hunted on the plains. Humans walked under lepidodendrons, the giant Carboniferous fern-trees we thought extinct along with the trilobites, 250 million years ago. Silurian Eurypterids, the giant sea scorpions, hunted in the shallows. Human-ancestor primates like Australopithecus and other species of humans like Neanderthals, must have also shared the earth with modern humans, if creationism is true.

Creationism means no fossils millions of years old. All that life preserved in rock lived no more than 10,000 years ago (and in some schools of creationism, 6,000 years ago). It must have been a frighteningly dangerous time, with all those giant predators on land, in the sea and air. And all of these creatures disappeared from the planet before 3,600 BCE, when the world’s oldest writing system was devised. Why? Because there is no written record of any of these plants, fish, arthropods, dinosaurs and giant mammals.

Or is there? Some creationists believe that nonsense, and have gone to many great lengths to “prove” the impossible: that humans and dinosaurs co-existed before written history. Claptrap. This is not better than the early creationists who claimed fossils are nothing more than natural formations of stone that look like bones, or that their deity inserted millions of fossils into the rocks to test believers’ faith. Some even claim scientists make fossils from plaster in factories in China! (Note that some museums have plaster casts made from authentic fossils.)

Such crap. Unadulterated, mindless, stupid crap.

Super-fast evolution: new species in just 6,000 years


Sea starsAccording to a recent story in Science Daily, new species of sea stars may have arisen in as little a time as 6,000 years.

Researchers studied the diversity in DNA sequences from sea stars of two related species to estimate how long it has been since the two species diverged. Their results showed a range from roughly 6,000 to 22,000 years ago.

That rules out some ways new species could evolve. For example, they clearly did not diverge slowly with genetic changes over a long period of time, but were isolated quickly.

Over the last 11,000 years, the boundary between cold and warm water in the Coral Sea has fluctuated north and south. A small population of the ancestral sea stars, perhaps even one individual, might have colonized a remote area at the southern end of the range then been isolated by one of these changes in ocean currents.

These two species of “cushion stars” – Cryptasperina pentagona and C. hystera – while they look very similar, are very different in many aspects – habitat and sex lives in particular.

Pentagona has male and female individuals that release sperm and eggs into the water where they fertilize, grow into larvae and float around in the plankton for a few months before settling down and developing into adult sea stars.
Hystera are hermaphrodites that brood their young internally and give birth to miniature sea stars ready to grow to adulthood.

Six thousand years is a remarkably short time for a significant evolutionary activity – about the entire length of recorded human history. And about as long as some creationist crackpots think the Earth has been in existence. But it’s not a one-speed-fits-all for evolutionary change. Even the longer 22,000 years is still remarkably short. That’s about when the first Europeans arrived in North America, or the length of the time it takes the remarkable planetoid, 2006 SQ372, to complete its orbit.

Earlier this year, Wired Magazine published a story about research to discover how long it would take for a mouse-sized animal to evolve to an elephant-sized one. And the answer was 24 million years.

That’s how many generations a new study estimates it would take to go from mouse- to elephant-sized while operating on land at the maximum velocity of change. The figure underscores just how special a trait sheer bigness can be.
“Big animals represent the accumulation of evolutionary change, and change takes time,” said evolutionary biologist Alistair Evans of Australia’s Monash University.
Evans and co-authors revisit a fossil record dataset of mammal body size during the last 70 million years, in a study published Jan. 31 in Proceedings of the National Academy of Sciences. The data was originally used to describe the evolutionary growth spurts experienced by mammals soon after dinosaurs ceased to be Earth’s dominant animals.
The relative sizes of mouse and elephant skulls. To go from mouse-sized to elephant-sized would take at least 24 million generations.
For the previous 140 million years, mammals had been rat-sized or smaller. With dinosaurs significantly reduced, mammals had a chance to fill newly vacant ecological niches, particularly that of the large-bodied plant-eater.

But what about human evolution? We have a pretty good record of our species’ evolution over more than 4 million years, from the apelike Ardipithecus through Australopithecus, Neanderthal, Cro Magnon to us. But we are, like other animals, still evolving. And the rate of evolution may be speeding up.

According to a story in National Geographic,

Explosive population growth is driving human evolution to speed up around the world, according to a new study.
The pace of change accelerated about 40,000 years ago and then picked up even more with the advent of agriculture about 10,000 years ago, the study says.
And while humans are evolving quickly around the world, local cultural and environmental factors are shaping evolution differently on different continents.
“We’re evolving away from each other. We’re getting more and more different,” said Henry Harpending, an anthropologist at the University of Utah in Salt Lake City who co-authored the study.
For example, in Europe natural selection has favored genes for pigmentation like light skin, blue eyes, and blond hair. Asians also have genes selected for light skin, but they are different from the European ones.
“Europeans and Asians are both bleached Africans, but the way they got bleached is different in the two areas,” Harpending said.
He and colleagues report the finding this week in the journal Proceedings of the National Academy of Sciences.

And some birds may be evolving faster, too – depending on their colour. According to a story in Science Daily in May,

Researchers have found that bird species with multiple plumage colour forms within in the same population, evolve into new species faster than those with only one colour form, confirming a 60-year-old evolution theory.
The global study used information from birdwatchers and geneticists accumulated over decades and was conducted by University of Melbourne scientists Dr Devi Stuart-Fox and Dr Andrew Hugall (now based at the Melbourne Museum) and is published in the journal Nature.
The link between having more than one colour variation (colour polymorphism) like the iconic red, black or yellow headed Gouldian finches, and the faster evolution of new species was predicted in the 1950s by famous scientists such as Julian Huxley, but this is the first study to confirm the theory.
By confirming a major theory in evolutionary biology, we are able to understand a lot more about the processes that create biodiversity said Dr Devi Stuart-Fox from the University’s Zoology Department.

So much science, so much research that continues to prove Darwin’s original theory, albeit much refined today thanks to our genetic research. You have to wonder, then, why 46% of Americans and 42% of Canadians and many others in the world still believe in the nonsense of creationism nor the pseudoscience of “intelligent” design.

I blame the continued survival of creationism on our failing education system with its lack of emphasis on science and its lack of training in critical thinking; on our society’s growing distrust in and disrespect for intellectuals; and the increasing influence of fundamentalist religion in politics.

Flatulent dinosaurs warmed ancient earth


Dino fartAn amusing story on Science Daily says researchers have determined that the giant, herbivorous sauropods of the Mesozoic might have been responsible for the era’s warm climate. Well, not the dinosaurs themselves, but rather the methane-producing bacteria in their guts:

“A simple mathematical model suggests that the microbes living in sauropod dinosaurs may have produced enough methane to have an important effect on the Mesozoic climate,” said Dave Wilkinson of Liverpool John Moores University. “Indeed, our calculations suggest that these dinosaurs could have produced more methane than all modern sources — both natural and man-made — put together.”

So basically, dinosaur farts created global warming. That would be one stinky environment.

Wilkinson, Ruxton, and Nisbet therefore calculate global methane emissions from sauropods to have been 520 million tons (520 Tg) per year, comparable to total modern methane emissions. Before industry took off on modern Earth about 150 years ago, methane emissions were roughly 200 Tg per year. By comparison, modern ruminant animals, including cows, goats, giraffes, and others, produce methane emission of 50 to 100 Tg per year.

Out-gassing animals have been blamed before as the cause of our recent climate changes. According to this site,

According to the Food and Agriculture Organization of the United Nations (FAO) agriculture is responsible for 18% of the total release of greenhouse gases world-wide (this is more than the whole transportation sector). Cattle-breeding is taking a major factor for these greenhouse gas emissions according to FAO. Says Henning Steinfeld, Chief of FAO’s Livestock Information and Policy Branch and senior author of the report: “Livestock are one of the most significant contributors to today’s most serious environmental problems. Urgent action is required to remedy the situation.”

The site’s conclusion is to “Eat less meat and dairy products.” Now if dinosaurs did better in the hotter climate of the Mesozoic, then curiously the same advice would have been suitable for carnosaurs, because eating the sauropods could have reduced the global climate. Fewer herbivores equals fewer farts equals less methane in the atmosphere equals cooler temperatures. Somehow I can’t see a T. Rex nibbling on the Cretaceous equivalent of broccoli in order to keep a warmer neighbourhood.

Just another example of the wonderful delights we find in the world of science.

Why the Republicans are bad for science


Tumblr imageRick Santorum’s recent win in the Mississippi and Alabama primaries are frightening for anyone who values science and critical thinking. Santorum is not the only Republican who frightens me. They all do. But Santorum most of all. The idea of a right-wing, homophobic, fundamentalist, creationist running the biggest and most powerful nation in the world is scary enough to keep me awake at night.

Santorum was the author of a 2001 amendment to the US education funding bill. His pro-creationist proposal was known as The Santorum Amendment. It “promoted the teaching of intelligent design while questioning the academic standing of evolution in U.S. public schools.” “Intelligent” design is anything but: it’s merely creationism dressed up in a cheap tuxedo. Santorum has a long history of “mischaracterizing” and misunderstanding evolution, as chronicled here: “…Santorum doesn’t need facts to back up his side, as long as he makes it sound like the other side has its own problems.”

Since Santorum’s failed attempt to get creationism inserted into the classroom, teaching so-called “intelligent” design has been declared unconstitutional by a US federal judge: “U.S. District Judge John E. Jones delivered a stinging attack on the Dover Area School Board, saying its first-in-the-nation decision in October 2004 to insert intelligent design into the science curriculum violates the constitutional separation of church and state.” The judge declared there was “overwhelming evidence” presented during the trial to prove “intelligent” design “is a religious view, a mere re-labeling of creationism, and not a scientific theory.”

That hasn’t stopped Santorum from being an outspoken advocate for creationism in whatever party dress it wears. Mitt Romney, his chief rival for the top spot, has been described as a “theistic evolutionist” based on older quotes, but he has said little or nothing about creationism during the campaign for the Republican candidacy.

In 2008, Santorum commented that, “…the theory of evolution… is used to promote to a worldview that is anti-theist, that is atheist.”

Creationist humourIn November, 2011, as the HuffPost reported, Santorum said, “the “left” and “scientific community” have monopolized the public school system’s curriculum, only permitting the teaching of evolution and leaving no room for the introduction of creation-based theories in the classroom.” Santorum bemoaned his frustration at the “whole ‘science only allows science to be taught in science class scenario.” Uh, Rick, that’s what you’re supposed to teach in a science class.

Creationism is not by itself a significant issue. It’s rather that it links to other, bigger issues. As Martin Wisckol writes,

While creationism itself rarely is the subject of political policy beyond school curriculum, it’s closely tied to high-profile issues that are – including abortion rights, stem cell use, gay marriage and birth control. And the most sizeable portion of the electorate subscribing to creationism are evangelical Christians… according to Pew researcher David Masci.

Santorum has other issues with science and scientific research aside from creationism. As Discover Magazine noted, Santorum doesn’t believe in climate change science. He doesn’t support stem cell research. Santorum called Barack Obama’s environmental policy, “some phony theology, not a theology based on the Bible” (see here – although that may have merely been a CYA retraction when his words were taken as a faith-based attack on Obama).

Early in the campaign, Romney distanced himself from Santorum’s ‘climate-science-is-political-science’ denial, by admitting he believed, “…the world is getting warmer, and I believe that humans have contributed to that.” (see here). But later he flip-flopped and said, “My view is that we don’t know what’s causing climate change on this planet. And the idea of spending trillions and trillions of dollars to try to reduce CO2 emissions is not the right course for us.” He also supports the rights of gas and oil companies to despoil the environment, including, “…drilling in the “the Gulf of Mexico, both the Atlantic and Pacific Outer Continental Shelves, Western lands, the Arctic National Wildlife Refuge, and off the Alaska coast.” Romney will be as bad for the environment as he will be for science, it appears.

It’s easy to target Santorum’s fundamentalist-Tea-Party-anti-science myopia and Romney’s pro-corporate-waste-the environment-deny-science position. But as Chris Mooney points out in this piece, even educated Republicans are prone to accept the same fallacies and narrow-minded views that characterize all of the presidential candidates:

Again and again, Republicans or conservatives who say they know more about the topic, or are more educated, are shown to be more in denial, and often more sure of themselves as well—and are confident they don’t need any more information on the issue.
Tea Party members appear to be the worst of all. In a recent survey by Yale Project on Climate Change Communication, they rejected the science of global warming even more strongly than average Republicans did. For instance, considerably more Tea Party members than Republicans incorrectly thought there was a lot of scientific disagreement about global warming (69 percent to 56 percent). Most strikingly, the Tea Party members were very sure of themselves—they considered themselves “very well-informed” about global warming and were more likely than other groups to say they “do not need any more information” to make up their minds on the issue.

Mooney calls it the “smart idiot” effect, and continues:

…well-informed or well-educated conservatives probably consume more conservative news and opinion, such as by watching Fox News. Thus, they are more likely to know what they’re supposed to think about the issues—what people like them think—and to be familiar with the arguments or reasons for holding these views. If challenged, they can then recall and reiterate these arguments. They’ve made them a part of their identities, a part of their brains, and in doing so, they’ve drawn a strong emotional connection between certain “facts” or claims, and their deeply held political values. And they’re ready to argue.

Rationality does not win the day, it seems, even with educated Republicans. Ideology does. And increasingly that ideology seems to be the products of a smaller and select group of uber-right media outlets (like Fox), self-appointed spokespeople (like the harridan Ann Coulter), and vocal Tea Party members. Ideology, as Martin Wisckol writes, is driving the debate about many issues, not facts – information, or empirical data:

…the “facts” used by voters are often subjective, depending on one’s political, philosophical and religious beliefs. The trend is growing, fueled in part by spurious information on the internet, and is a major reason for partisan gridlock in Sacramento and Washington.
Thirty percent of Republicans say manmade global warming is occurring, while 64 percent of Democrats say that’s the case, according to Pew Research Center. Pure creationism – which says man was created by God in his current form – is subscribed to by 52 percent of Republicans and 34 percent of Democrats, according to Gallup. Pew found the difference on creationism to be a closer – but still substantial – 39 percent to 30 percent.
And it’s not just evolution and global warming that are too complex for most voters to thoroughly assess based on data. The comparative efficiency of health-care policies, the effect of a large deficit, the best way to reduce the debt and how to stimulate the economy are other key areas where factual understanding doesn’t determine a voter’s position so much as their preexisting ideology and whose word they’re inclined to trust.

Sad to think that during the Enlightenment, governments supported the quest for learning. In the 21st Century, Republicans want the government to support ignorance and superstition.

NASA latest target of creationist harridans


CreationismA former NASA computer technician has filed an wrongful dismissal suit against his former employer, alleging he was, “discriminated against because he engaged his co-workers in conversations about intelligent design.” Engaged is a mild word. From what I’ve read in more balanced reports, he proselytized and his co-workers complained. The trial began Monday (documents here).

David Coppedge admitted he, “…handed out (religious) DVDs on the idea while at work.” But that’s not all. According to this AP story, Coppedge was also involved in political campaigning at work:

Coppedge’s attorney, William Becker, contends his client was singled out by his bosses because they perceived his belief in intelligent design to be religious. Coppedge had a reputation around JPL as an evangelical Christian, and interactions with co-workers led some to label him as a Christian conservative, Becker said.
In the lawsuit, Coppedge says he believes other things also led to his demotion, including his support for a state ballot measure that sought to define marriage as limited to heterosexual couples and his request to rename the annual holiday party a Christmas party.

Coppedge runs an apologist creationist website that tries to discredit evolutionary and biological science and new discoveries with pseudo-scientific jargon.

The Huffington Post story noted,

While the case has attracted interest because of the controversial nature of intelligent design, it is at its heart a straightforward discrimination case, said Eugene Volokh, a professor of First Amendment law at the University of California, Los Angeles School of Law.

“Intelligent” design is not controversial unless you try to promote it in your workplace to skeptical coworkers. Creationist advocates get shirty that your efforts get you dismissed. The story continues:

“The question is whether the plaintiff was fired simply because he was wasting people’s time and bothering them in ways that would have led him to being fired regardless of whether it was about religion or whether he was treated worse based on the religiosity of his beliefs,” said Volokh. “If he can show that, then he’s got a good case.”

The CBC story quoted John West, associate director of the inappropriately-named, right-wing anti-science “Centre for Science and Culture” at the creationist defence group, the “Discovery Institute” (aka The Discoveroids*)

“It’s part of a pattern. There is basically a war on anyone who dissents from Darwin and we’ve seen that for several years. This is free speech, freedom of conscience 101.”

The US Constitution protects free speech from government interference. It doesn’t protect anyone’s right to disrupt a workplace. There is no constitutional right to promote creationism in the workplace.

No, it isn’t free speech or conscience. It’s a typical creationist assault on science through a wedge issue. West is using typical pro-creationist/anti-science spin doctoring. In this quote, he tries to reposition the issue from one of a workplace problem to one of constitutional freedom and faith. It is neither. It’s not a war on dissent**. It’s about whether Coppedge was engaged in workplace harassment. The only “war” going on is the constant creationist assault on critical thinking.

Would these people defend someone who actively promoted astrology at JPL? Or promoted Communism? Or is protecting “free speech” limited to defending the alleged right to spout creationist folderol?

Coppedge’s attorney, William Becker, says his client was singled out by his bosses because they perceived his belief in intelligent design to be religious. Coppedge had a reputation around JPL as an evangelical Christian and other interactions with co-workers led some to label him as a Christian conservative, Becker said.
In the lawsuit, Coppedge says he believes other things also led to his demotion, including his support for a state ballot measure that sought to define marriage as limited to heterosexual couples and his request to rename the annual holiday party a “Christmas party.”

Belief in “intelligent” design IS religious. Only religious fundamentalists or biblical literalists believe in creationism. But belief alone won’t get you fired.

Live Science notes:

According to Coppedge’s complaint first filed with the courts in April 2010, JPL supervisors reprimanded Coppedge for handing out intelligent design DVDs to coworkers and discussing his beliefs about intelligent design with them. Coppedge alleges that JPL stifled his right to free speech and created a hostile work environment, demoting him from his “team lead” position in 2009. Coppedge lost his job last year.
“Plaintiff contends that, as a direct and proximate result of Defendants’ conduct and actions, he has been prejudiced and harmed as the result of Defendants’ actions suppressing and constraining protected speech in the workplace on account of viewpoint, content and religion,” reads Coppedge’s complaint filed at the Los Angeles Superior Court in 2010. The complaint has since been updated to include Coppedge’s termination.
According to JPL, it was not Coppedge’s beliefs, but his conflicts with colleagues that led to his demotion. The lab also holds that Coppedge’s firing was the result of planned budget cuts, not his intelligent design beliefs.

Strikes me that handing out religious DVDs or campaigning for a homophobic state proposition in any workplace during work hours are inappropriate acts. The US Constitution protects free speech from government interference. It doesn’t protect anyone’s right to disrupt a workplace. There is no constitutional right to promote creationism in the workplace.

Far more frightening is the rest of the story about the dumbing down of America:

According to the Gallup polling organization, as of 2010, 38 percent of Americans believed that humans evolved with God’s guidance, a position roughly congruous with intelligent design. Forty percent said they believed that God created humans in their present form, while 16 percent said they believed that humans evolved without God’s hand.
The Pew Research Center… in 2005… found that about 58 percent of Americans said the biblical account of creation was definitely or probably true, but the same percentage also said the same of evolution. In August 2005, a Gallup poll found that only 52 percent of Americans knew what the term “intelligent design” meant.
One study published in January found that people’s acceptance of evolution depends on their gut feeling rather than a careful examination of the evidence.
Nonetheless, evolution, creationism and intelligent design remain hot political topics. Legislators in several states introduced legislation this year that would limit the teaching of evolution or promote instruction in creationism.

Those figures are truly frightening and bode ill for science and critical thinking. Forty percent believe in creationism, while only 16% believe humans evolved without supernatural intervention. That’s sad. So very, very sad.

Creationism is fraudulent pseudoscience***. Claptrap. Codswallop. “Intelligent” Design (ID) is simply lipstick on the creationist pig. It isn’t science any more than “faith healing” is medicine.

The Sensuous Curmudgeon has been following the trial and commenting on the pieces creationist groups have been posting on their websites in their attempt to recast the case as a battle over faith rather than a workplace discipline issue. His archive of posts is here.

One example of the fundamentalist spin is this screed from an uber-right site:

In a developing case indicative of the growing war on religion and in particular Christianity, opening statements are expected Monday in a legal case involving the wrongful termination of a NASA Jet Propulsion Laboratory employee…
Anyone who has ever been a Christian in a secular workplace characterized by a decidedly anti-religious environment knows all too well that this kind of “labeling” and discrimination is common place. Though JPL will advance all kinds of evidence to defend its demotion and ultimate firing of Coppedge, most unbiased Americans can read between the lines and see that what really went on here was a coordinated and widespread effort to get rid of that ignorant Christian trouble-maker. Heaven forbid somebody in NASA actually believe in God or Intelligent Design – that is pure unadulterated blasphemy to today’s breed of scientists!

Typical creationist/fundamentalist hookum. Free speech is a canard in this trial.

People are allowed to believe any tomfoolery they want, even creationism, the apex of tomfoolery, up there with with astrology, phrenology, crystal therapy and alien abductions. All of which have many, many followers. But believers can’t annoy co-workers with their beliefs and disrupt the workplace. And that’s what NASA alleges Coppedge did.

* My favourite quotes from the Discoveroids’ website: “The Spanish Inquisition was about testing the sincerity of people’s Christianity.” “Darwinism is the tribal religion of the modern elites, presided over by The New York Times, NPR/PBS and even The Wall Street Journal.” “Ann Coulter is so funny that people fail to notice the well read public intellectual behind the laughing smile and endless blonde tresses.” (Ann Coulter is the poster girl of the uber-right wingnut caucus who personifies the term ‘shrill harridan’). Guffaws all around.
** Many scientists have challenged Darwin’s original ideas. Evolutionary theory has evolved in its own way from Darwin’s day. That’s natural (like evolution). Darwin didn’t know about genetics, DNA, viruses, radiation and other things that affect development and mutation. So of course scientists have had to refine and adapt the original theory in the light of new information. Science grows with knowledge, unlike creationism which stopped thinking about things 4,000 years ago when the Genesis mythology was first penned. Today’s evolutionary biology is far more complex and fuller than what Darwin proposed. But that doesn’t mean Darwin was wrong, any more than Newton or Galileo are wrong simply because we’ve learned new things since either.
*** Creationism is the belief that the first creation myth in the Book of Genesis is fact, not primitive mythology. Curiously, the different and contradictory second creation myth (2:4-2:25) gets ignored.
