Seeing evolution in action


Peter and Rosemary GrantThe pop-science notion is that evolution takes a long time. Millennia, many millennia; even millions of years. But is that always true? Can one actually see and measure evolution in action? Can it happen in such a short time as to be recorded?

Peter and Rosemary Grant say they have. And it’s the subject of a new book they co-authored based on their research.

Their story was reported in the April 23 issue of the Princeton Alumni Weekly. It’s a terrific read if for nothing more than their 40-year tale of dedication, science and adventure on the isolated Daphne Major Island, one of the smaller islands of the Galapagos chain.

Forty years studying finches together, away from human company, away from the comforts of civilization. The small birds that first gave Charles Darwin insight into the mechanics of natural selection were their focus. And the Grants report they have seen that mechanism in action on the island.

Scientists previously had reported seeing the processes of natural selection among bacteria, honeycreepers, cichlid fish, and fruit flies. As Peter Grant puts it, “Until we began, it was well understood that agricultural pests and bacteria could evolve rapidly, but I doubt that many people thought that about big, vertebrate animals.”

The Grants believe that hybridization is an important force in the rise of new species, and think this applies, too, to human evolution. For a long time, for example, paleontologists believed that Neanderthals and “modern homo sapiens” did not interbreed when they came into contact in prehistoric times, but recent research indicates that about 20 percent of Neanderthal genes have been preserved in our species. “It’s almost been a hobbyhorse of ours,” Peter says. “We were saying, ‘I bet there has been gene exchange between the lineages of homo sapiens throughout their evolution.’”

The Grants’ new book is targeted at both lay readers and scientists familiar with their work, and broadly discusses their findings about natural selection, hybridization, population variation (why do some populations of birds vary more dramatically in beak size?), the potential vanishing of a species through interbreeding, and, of course, the potential origin of a new species — the Big Bird lineage. They also touch on global warming and its possible effect on Darwin’s finches. Most of all, the book is an affirmation of the importance of long-term fieldwork as a way of capturing the true dynamism of evolution.

Pseudo-patriotic madness


FluffernutterThis is news, right from the CBC, not April Fool or The Onion:

The Massachusetts House of Representatives has finally granted initial approval to a Bill naming the Fluffernutter the official state sandwich. The bill was filed in 2006 by then Representative Kathi-Anne Reinstein, in response to a motion by State Senator Jarrett Barrios limiting school Fluff servings to once a week. She thought that motion was, ‘nuts’.
The Fluffernutter is a peanut butter and Marshmallow Fluff combination and has been a staple in Massachusetts diets for generations.

Okay, for anyone with any shred of common sense left, that isn’t news. It’s insanity. Sheer, unbridled, unrepentant nuttiness. It’s crazier than a bagful of bloggers. And why is the media even giving this “serious” coverage instead of railing on about the uselessness of these addle-brained state politicians?

An official “state sandwich?” One that, by the way, has its own song

Oh you need fluff, fluff, fluff
To make a fluffernutter
Marshmallow fluff
And lots of peanut butter…

What next? An official state salad dressing? State muffin? State flatbread? State sushi roll? Does a state need an official everything? Apparently so. That simply takes patriotism into the realm of insanity. I can hardly wait for the debate of the official state vacuum cleaner bag…

Not to mention the incredibly stupid mixture of junk food a fluffernutter represents – plus a name that just begs to be lampooned.

Fluffernutter? Sounds like a porn-movie extra. You can expect the jokes to make the social media rounds any time now. And the angry rants about politicians blind to issues of obesity and health.

The dangerous idiocy of the anti-vax movement


Measles outbreakMeasles is on the rise in Canada. There have already been many cases in 2014: in PEI, London, Ottawa, southern Alberta, Regina, Qu’Apelle, Calgary, Fraser Valley (320 cases), Hamilton, Halton, Edmonton, Winnipeg, Waterloo, Nanaimo and other locations. Eleven cases in Ontario this year alone. Nine in Alberta.

That ancient, deadly foe we recently believed we had conquered, is coming back. And it’s going to kill children again, this time with the complicity of their parents.

Fifty years ago, science found the cure and made a vaccine for it. In 2000, the United States optimistically declared ongoing measles transmission had been eliminated. But it’s come back.

So have mumps and whooping cough – both easily and safely prevent by vaccinations. Both are deadly threats to children again.

Who’s to blame? And why is this happening? Why are people putting children at such risk?

It’s because of the anti-vaccination movement, a cult of pseudoscience, anti-medicine sentiments, gullibility, fear, superstition and mostly quackery promoted by witless and devious celebrities and greedy marketers, then spread on the internet to people who jump on every passing bandwagon. Parents who get their medical advice from unreliable online sources – mostly lies, rumour, gossip and unfounded allegation, like all conspiracy theories – or from quacks, not doctors.*

Health Link Alberta tells us how easily measles can spread:

Close contact with an infected person is not necessary to catch measles.
It is an extremely contagious airborne disease that can spread by coughing and sneezing, and through air currents.
Although there is no specific treatment or cure for measles, it can be prevented through immunization.
The measles, mumps and rubella (MMR) vaccine is part of the routine childhood immunization program in Alberta.
Children should receive their first MMR dose at 12 months and the second between the ages of four and six years. Both doses are required to be fully protected.

The anti-vaxxers are creating a public health disaster. Rather ironically, North American parents have that in common with the Taliban:

In Pakistan, polio remains an epidemic because the Taliban has banned aid workers from vaccinating children. They say they fear that vaccination efforts are simply a ruse meant to disguise espionage. Health workers attempting to distribute vaccines there have been attacked and killed. A total of 101 polio cases have been reported in the country as of mid-November, and another 240,000 children have not been vaccinated.

The ethics of politics via Aristotle


Aristotle PoliticsPolitics, Aristotle wrote in the Nicomachean Ethics, is the “master science of the good.” The good of which he wrote is the greater good, the “highest good” that benefits the state, not the personal.

For even if the good is the same for the individual and the state, the good of the state clearly is the greater and more perfect thing to attain and safeguard. the attainment of the good for one man alone is, to be sure, a source of satisfaction; yet to secure it for a nation and for states is nobler and more divine.

But good is hard to define, Aristotle wrote, and full of “irregularity” because, he added, “in many cases good things bring harmful results.”

For Aristotle and his fellow philosophers, politics was the science of figuring out what is conducive to life in a polis or city (which in the Greece of his day were city states); it determined how people can live together in communities and cities. It still is, which is why his 2,000-plus year-old work, Politics, is still taught in poli-sci courses.

Politics also has the practical side: the legislative component. And ethics underlies both parts.

Ethics and virtue are interconnected in Aristotle, but it’s not entirely the same virtue of which Machiavelli writes (and Aristotle described many more virtues than Plato’s four: courage, wisdom, temperance and justice). Aristotle’s virtue is a mean between excess and deficiency. It isn’t being super good, or unbendingly upright, or sticking to a dogma or theological script.

It’s almost like situational ethics (see Nicomachean Ethics, Book I.7). The BBC notes:

Situation ethics teaches that ethical decisions should follow flexible guidelines rather than absolute rules, and be taken on a case by case basis.

As this site notes:

Aristotle says that it is a mean between extremes, but not a mechanically determinable mean: “to feel them at the right times, with reference to the right objects, towards the right people, with the right motive, and in the right way”

For example, the mean between obsequiousness and cantankerousness is friendliness (see here). Angry, vituperative blogs full of accusation and wild allegation would not fit Aristotle’s definition of virtuous because they have a deficiency of social conduct, according to the chart.

As this site explains:

The good for human beings, then, must essentially involve the entire proper function of human life as a whole, and this must be an activity of the soul that expresses genuine virtue or excellence.

It also notes:

True happiness can therefore be attained only through the cultivation of the virtues that make a human life complete.

Cultivation: it means virtues have to be consciously worked at, and practiced. They are not innate or hereditary.

Reading: A Canadian tragedy… or not?


World Reading Map
The map above might show the making of a serious tragedy for Western and especially Canadian culture. It indicates in colour which nations read the most. Yellow is the second lowest group. Canada is coloured yellow.

TV zombiesIn this survey, Canada ranks 10th – from the bottom! Twenty countries above us have populations which, on the average, read more per week than we do. That surprises and shocks me. And it disappoints me no end.

I’m not only a voracious reader, I’m passionate about books, language, reading and writing, and have been on the library board for 20 years actively helping it grow and develop. Is it a futile task?

I don’t believe so. In fact, I’ve seen the library grow more and more into a vital community resource in the past two decades. It has more users, more books and more reads than ever. That flies in the face of what the map suggests.

The map showed up on Facebook via Gizmodo, The stats come from the NOP World Culture Score (TM) Index (press release here). They’re scary – but are they accurate? They’re certainly not recent: the data were collected between December 2004 and February 2005.

Here are the 30 countries, ranked by the number of hours people there read every week:

  1. India — 10 hours, 42 minutes
  2. Thailand — 9:24
  3. China — 8:00
  4. Philippines — 7:36
  5. Egypt — 7:30
  6. Czech Republic — 7:24
  7. Russia — 7:06
  8. Sweden — 6:54
  9. France — 6:54
  10. Hungary — 6:48
  11. Saudi Arabia — 6:48
  12. Hong Kong — 6:42
  13. Poland — 6:30
  14. Venezuela — 6:24
  15. South Africa — 6:18
  16. Australia — 6:18
  17. Indonesia — 6:00
  18. Argentina — 5:54
  19. Turkey — 5:54
  20. Spain — 5:48
  21. Canada — 5:48
  22. Germany — 5:42
  23. USA — 5:42
  24. Italy — 5:36
  25. Mexico — 5:30
  26. U.K. — 5:18
  27. Brazil — 5:12
  28. Taiwan — 5:00
  29. Japan — 4:06
  30. Korea — 3:06

Canada is listed well below the global average of 6.5 hours a week. Five-point-four-eight hours translates into a mere 49 minutes a day, on average. Are we losing our minds to TV?

Running for re-election in 2014


Earlier this month, I filed my nomination papers for municipal council. I am running for a fourth term as Collingwood councillor. I will post a new election website with updated information and campaign content later this winter.

I would appreciate your support, your trust and your vote. I believe I have earned them during my time on council, and will continue to do my best to serve the residents of Collingwood, and meet the needs of our growing community, when re-elected.

Until the new website is available, I want to let any eligible Collingwood voters who wish to contact me about issues, events and activities to feel free to do so. You can contact me by email. If you want to talk in person, please send me your phone number and a good time to call or to arrange a meeting.

I have a Facebook page where I will also post updates and related municipal content, as I always have done. I will launch a separate Twitter account for political campaigning this winter. Should you wish access to my personal Twitter feed (@iwchadwick – not used for political campaign content), please post a follower request on Twitter.

I stand on my experience, reputation, my integrity and the very positive results this council has accomplished this term. This has been the most productive, engaged, open and dedicated council I have served on, and reported on while I was reporter in the local media. I am proud to have been able to serve the town on this council; proud to have contributed to those accomplishments.

This term I have also been fortunate to share my political and media experiences with other politicians through articles and books published by Municipal World (three books and numerous magazine articles published, with a fourth book and new article due in 2014). I am passionate about municipal politics, about good governance, about public engagement, and I hope my writing expresses that.

I am also passionate about Collingwood. We live in the best community in Ontario: we have exceptional natural beauty; a stunning heritage downtown; low crime; lovely, walkable streetscapes; we have a solid workforce; many employment opportunities; we are centrally located in Ontario’s all-season playground and we have a good municipal staff at town hall to help council implement its strategic goals.

I love this town, and have been actively involved in it ever since we moved here, almost 25 years ago. I have been engaged as a volunteer on many boards and committees, and participated in service club activity. I believe in giving back to our community to help keep it the best place to live. Being on council has helped me give back in the best way possible.

If you would like to help my campaign or contribute, please contact me.

Crossing the line


HuffPostThere’s a story on ipolitics that in part echoes my own thoughts about media and responsibility. Yet the author draws different conclusions than I believe I would have, were I still in the media.

It’s called “Paul Calandra and the tale of the naked senator” and it’s written by Paul Adams. Worth reading regardless of whether you agree or not.

Adams writes about the quandary many reporters and editors find themselves in: trying to define the boundary between public interest and privacy. It’s an issue that has raised its head many times in the past, but moreso this past year.

This debate must have raged (or at least I hope it raged) in the editorial offices of the Toronto Star in late 2013, when the paper decided to release a video of Mayor Ford - apparently intoxicated and raging – that clearly had nothing to do with Ford’s political office or his abilities. And, since there was no way to identify the context of of Ford’s comments, the viewer had no way to tell who he was ranting about, even if it was a real person rather than a TV show character.

The Star itself admitted:

The target of the mayor’s anger in the video is not in the room and is not known to the Star.

yet it ran the video with a lengthy story to accompany it.

To me, the Star opened a Pandora’s box. If the mayor has no private life outside his office when he is not in the public eye, then should that be true, too, for the Star’s staff? If it is fair to show a video of a private moment (surreptitiously recorded in someone’s home, not a public place), then why would it not be equally (and morally) correct to show videos of TorStar editors and reporters at their worst?

The argument is often made that elected politicians represent their office 24/7, so they have no private persona when in office, just a public face. But is that not also true of police? Of doctors? Pilots? In fact, we associate most people with their jobs and their social positions regardless of the time of day, or their location. They represent their position, their employer 24/7, even when not in the job, just like politicians. Thanks to social media, we have no clear definition of private and public lives.*

If our personal behaviour reflects on our roles and jobs no matter whether we are in our office, in private, on our Facebook page, in a restaurant or on a golf course, so it must be equally true of the media. After all, can a reporter stop being a reporter or representing the paper he/she works for  when out of the office any more than a mayor stop being a mayor? I don’t think so. That’s one reason why the Star should have been reluctant to release the video.

But the real reason is discretion. What purpose does such sleaze serve? is there a greater good in ridiculing and embarrassing the mayor over a private matter? All it does is smear the city’s reputation worldwide, make the entire city the butt of ridicule. And discredit the Star.

Adams says the parliamentary press corp has,

“A highly developed prurient interest coupled with a equally powerful culture of discretion about what should be shared with the Canadian people.”

That should be refreshing, but I doubt it’s a sentiment shared among all journalists, as the TorStar video release shows. In fact, I’d suggest that it wasn’t discretion at all, but rather partisan politics that made the media act as it did in Adam’s tale of two events.
