Group selection theory attempts a comeback

Over the past few weeks, in commemoration of the 200th anniversary of Darwin's birthday, we've seen many articles published on the topic of evolution. The November 20, 2008 edition of Nature contains a drawing of Darwin on the cover, and the entire issue is titled "Beyond the Origin." Inside this issue is an article by Marek Kohn titled "The Needs of the Many," an article summarizing current thinking on group selection. Kohn carefully sets out some definitions at the beginning of his article. For instance, he recognizes that modern evolutionary theory is based on the idea that selection "sees" individuals and acts on them through the genes they embody. Compare that to "group selection":

The idea that evolution can choose between groups, not just the individuals that make them up--has a higher profile today than at any time since its apparent banishment from mainstream evolutionary theory. And it gets better press, too. This is in part owing to the efforts of David Sloan Wilson of Binghamton University in New York, who argues that the dismissal of group selection was a major historical error that needs to be rectified. And it does not hurt that he has been joined by Edward O. Wilson, the great naturalist and authority on social insects. They and many others have worked to reposition group selection within the broader theme of selection that acts simultaneously at multiple levels.

Buried in the dispute about the extent to which group selection occurs are numerous definitional issues such as the proper way to define "group," "altruism," and "selfishness."

How to follow the Bible literally.

Writer A. J. Jacobs embarked upon a one-year attempt to follow all of the rules in the Bible. To do so, he first wrote down every rule he spotted in the Bible (he came up with 700). Following those rules was difficult, however, especially when he didn't quite understand them. For instance, where are the "corners" of one's beard? Though his talk is often humorous, Jacobs reveals some serious epiphanies he had along the way. For instance, he found that his behavior sometimes changed his thoughts (he found that visiting sick people made him more compassionate rather than the other way around). He learned to give thanks for the hundreds of things that went right every day, rather than focusing on the few things that went wrong. He learned to have reverence for many aspects of his life, even though he remained an agnostic through the whole experience. He also learned that he shouldn't completely dismiss that which is irrational, and we all have irrational aspects of our lives (is blowing out birthday candles on a cake rational?). You'll enjoy Jacobs' understated delivery and his respect for those who are different. His talk is well worth a viewing, no matter where you fall on the belief continuum.

Pregnant women breakdancing?

Pregnant woman were out in droves to breakdance to draw attention to a good cause. It happened in London in September 2008. The stats say it all: every day 1,400 women die in labor and child birth. Here's the video: BTW, at the end of the video, you'll hear that the women who were actually breakdancing were not actually pregnant.

Another Near Miss

In case you missed it, asteroid 2009 DD45 passed the Earth today at a distance of about 1/7th of the way to the moon. It was noticed about 3 days ago, and apparently has an orbit that will bring it close to home every so often. See here. It is relatively tiny, about 30 meters across. Therefore, when it hits it'll only make a hole a few miles across. Maybe the size of Manhattan or the Greater Chicago area. Yes, when. It'll probably hit in the ocean, in which case only seaside towns will be destroyed, like Miami, D.C, or Los Angeles. But this is only one of thousands that have been discovered so far. No need to worry. When the sky does fall, we'll find out eventually. With a bit of pork barrel spending, we might be able to predict and prevent such things. But it might cost as much as the current bailing out of mismanaged banks. But I've discussed the end of the world before.

We get mail

At the Red Cross, we get lots of mail. Mostly it's our own reply paid envelopes with cheques in them, sent in response to a quarterly mailout. In a time of crisis (like now: redcross.org.au) it's all kinds of envelopes from all kinds of people with lots of different stamps for me to harvest and decorate my cubicle with. Sometimes, amidst the cheques and postal orders, we might also get a letter or card from an old digger or Red Cross lady with a "The War" story, or perhaps a tale of how the good ol' Red Cross came through for them when they were in a POW camp. We also get people complaining about how much mail we send them because it must cost us so much money to send all those letters (the complainants usually use our own reply paid envelopes - or call our 1800 number - to do so, which, um, costs us money). Occasionally we even get white-hot rage and four-lettered, multicoloured profanity in response to such a mailout (that's for another adults-only post). Even less frequently, we get poetry. The following - well, I guess you could call it a poem as I'm not sure what else it should be called - came in a card attached to a donation . . .
