Global warming + evolution = species explosion!!!


Three of the candidates in the recent

Three of the candidates in the recent Republican presidential debate said they don’t believe in evolution: Colorado Representative Tom Tancredo, Kansas Senator Sam Brownback, and former Arkansas governor Mike Huckabee. Hard to believe that this is 2007 and not 1807. John McCain said he did believe in evolution but that “I also believe, when I hike the Grand Canyon and see it at sunset, that the hand of God is there also”.

Update: An earlier version of this post wrongly stated that Mitt Romney raised his hand when asked about disbelieving evolution…Tom Tancredo was the third person. (thx to several who wrote in about this)


Humans are the animal world’s best distance

Humans are the animal world’s best distance runners…we can run long distances relatively fast without overheating. “Once humans start running, it only takes a bit more energy for us to run faster, Lieberman said. Other animals, on the other hand, expend a lot more energy as they speed up, particularly when they switch from a trot to a gallop, which most animals cannot maintain over long distances.” (via beebo)


Men look at crotches

Among the many interesting things in Online Journalism Review’s article about using eyetracking to increase the effectiveness of news article design is this odd result:

Always look crotch

Although both men and women look at the image of George Brett when directed to find out information about his sport and position, men tend to focus on private anatomy as well as the face. For the women, the face is the only place they viewed. Coyne adds that this difference doesn’t just occur with images of people. Men tend to fixate more on areas of private anatomy on animals as well, as evidenced when users were directed to browse the American Kennel Club site.

That is absolutely fascinating. I’d love to hear an evolutionary biologist’s take on why that is.

I’m also heartened by the article’s first featured finding: that tighter writing, more white space, and jettisoning unnecessary imagery helps readers read faster and retain more of what they’ve read.


Why do we believe in God?

The cover story in this week’s NY Times Magazine is called Darwin’s God and covers, from an evolutionary biology standpoint, why people believe in God. Most scientists studying the matter believe that humans have a built-in mechanism for religious belief. For instance, anthropologist Scott Atran sometimes conducts an intriguing experiment with his students:

His research interests include cognitive science and evolutionary biology, and sometimes he presents students with a wooden box that he pretends is an African relic. “If you have negative sentiments toward religion,” he tells them, “the box will destroy whatever you put inside it.” Many of his students say they doubt the existence of God, but in this demonstration they act as if they believe in something. Put your pencil into the magic box, he tells them, and the nonbelievers do so blithely. Put in your driver’s license, he says, and most do, but only after significant hesitation. And when he tells them to put in their hands, few will. If they don’t believe in God, what exactly are they afraid of?

Or rather, why are they afraid? One possible reason is that humans are conditioned to be on the lookout for “agents” and we tend to find them even when they’re not there:

So if there is motion just out of our line of sight, we presume it is caused by an agent, an animal or person with the ability to move independently. This usually operates in one direction only; lots of people mistake a rock for a bear, but almost no one mistakes a bear for a rock.

What does this mean for belief in the supernatural? It means our brains are primed for it, ready to presume the presence of agents even when such presence confounds logic. “The most central concepts in religions are related to agents,” Justin Barrett, a psychologist, wrote in his 2004 summary of the byproduct theory, “Why Would Anyone Believe in God?” Religious agents are often supernatural, he wrote, “people with superpowers, statues that can answer requests or disembodied minds that can act on us and the world.”

Another reason for the instinctive religious impulse may be that people are able to put themselves in other peoples’ minds, to think about how another person might be feeling or thinking:

Folkpsychology, as Atran and his colleagues see it, is essential to getting along in the contemporary world, just as it has been since prehistoric times. It allows us to anticipate the actions of others and to lead others to believe what we want them to believe; it is at the heart of everything from marriage to office politics to poker. People without this trait, like those with severe autism, are impaired, unable to imagine themselves in other people’s heads.

The process begins with positing the existence of minds, our own and others’, that we cannot see or feel. This leaves us open, almost instinctively, to belief in the separation of the body (the visible) and the mind (the invisible). If you can posit minds in other people that you cannot verify empirically, suggests Paul Bloom, a psychologist and the author of “Descartes’ Baby,” published in 2004, it is a short step to positing minds that do not have to be anchored to a body. And from there, he said, it is another short step to positing an immaterial soul and a transcendent God.

There’s lots more in the article…it’s well worth a read.

Richard Dawkins: Why there almost certainly is no God. “We cannot, of course, disprove God, just as we can’t disprove Thor, fairies, leprechauns and the Flying Spaghetti Monster. But, like those other fantasies that we can’t disprove, we can say that God is very very improbable.”

Over the years, Mickey has become more well-behaved and his appearance more juvenile (larger eyes, short pudgy legs, relatively large head, short snout, etc.). “When we see a living creature with babyish features, we feel an automatic surge of disarming tenderness.”

The AAAS, the organisation which publishes Science magazine, has produced a book called The Evolution Dialogues. “Meant specifically for use in Christian adult education programs, it offers a concise description of the natural world, as explained by evolution, and the Christian response, both in Charles Darwin’s time and in contemporary America.” (thx, mike)


Public acceptance of evolution is relatively low

Public acceptance of evolution is relatively low in the US and is getting lower. “American Protestantism is more fundamentalist than anybody except perhaps the Islamic fundamentalist.”

Update: Here’s a graph of the results. Yikes.


Natural deselection

Tom Coates recently checked out the Royal College of Art Summer Show in London and ran across this project by Tim Simpson:

Natural Deselection

…three plants compete to reach the light that feeds and nourishes them. The first one to succeed survives. The other two are automatically cut down in their prime.

First plant to grow close to the proximity sensors wins. A simple and elegant idea.

To Dr. David Hague, human pregnancy is

To Dr. David Hague, human pregnancy is a struggle between the fetus and mother. Evolutionarily speaking, the fetus “wants” as many resources as possible for itself while the mother “wants” to do what she can to spread her resources across as many children as possible. In theory, this is a cause of the many serious health problems surrounding pregnancy.

Update: Carl Zimmer has more about this on his blog.

The Dover, PA evolution vs. intelligent design

The Dover, PA evolution vs. intelligent design ends with the judge ruling against the teaching of ID in the classroom because it violated the “constitutional ban on teaching religion in public schools”. “We find that the secular purposes claimed by the board amount to a pretext for the board’s real purpose, which was to promote religion.”

There’s a Charles Darwin exhibition at the Natural History Museum in NYC through May 2006. A tidbit not reported in the US press: the exhibition failed to attract corporate sponsorship because “American companies are anxious not to take sides in the heated debate between scientists and fundamentalist Christians over the theory of evolution”. Pussies.

Update: This letter sent into TMN throws some doubt on the whole lack of corporate sponsorship angle. (thx, chris)

Not only is Intelligent Design bad science,

Not only is Intelligent Design bad science, it’s also bad religion. “Self-defeating and incoherent, Intelligent Design is worse than useless, not only as science but also, one imagines, for religious folks who might be attempting to understand God by working backwards from the world as their body of evidence.”


Kansas is in quite a state

I know I’m not supposed to be paying attention to anything other than my Asia trip, but I read about the Kansas Board of Education approving the teaching of “theory” of intelligent design in public schools in the South China Morning Post this morning and…

AAAAAAAAAAAAAAAAAARRRRRGGH!!!!!!!!!

What the hell, Kansas? And those poor science teachers in Kansas public schools…what are they supposed to do? Teaching pseudoscience as real science, that’s like asking the math teachers to tell the kids that 2+2=5 because God said so. You can’t quit, because then those kids will really be lost. If you don’t teach that ID is valid science, you’ll probably get reprimanded or fired. So what to do? I have a couple of suggestions:

1) Teach your students about evolution, and then tell them about intelligent design, just as the state curriculum says. Then spend some time going over what science is, what a theory is, and so on. Apply the definition to each. That way, you’ve taught ID by the books and then demonstrated its relationship to science.

2) Or, as long as you’re teaching your students that a higher power designed the world/universe, why not take it a step further and tell them about your personal and scientific belief in The Flying Spaghetti Monster? As long as science can include anything now, why not a supernatural being made from pasta?

Update: There appears to be hope. In Dover, Pennsylvania:

In that small, relatively conservative Pennsylvania town, voters booted all eight Republican pro-intelligent design school board members who were up for re-election and replaced them with Democrats who oppose the curriculum policy. Dover is not some bastion of liberal politics; it’s more like Kansas than parts of Kansas are.

Why do people believe in God? Evidence

Why do people believe in God? Evidence suggests that it’s partially inherited. “The degree of religiosity was not strongly related to the environment in which the twin was brought up. Even if one identical twin had been brought up in an atheist family and the other in a religious Catholic household, they would still tend to show the same kind of religious feelings, or lack of them.”

The only debate on intelligent design that is worthy of its subject”. Hootingly funny. (And I have no doubt that someone from the other side of the debate could construct something equally as amusing, so…)
