Islam and Evolution

Bracing for Islamic Creationism (PDF). "To avoid a vast rejection of evolution in the Muslim world, scientists can present the theory as the bedrock of biology and can stress its practical applications." [Via]

The unfortunate burden of genius

Medical studies have indicated that high intelligence is often synonymous with the likelihood of alcoholism and suicidal tendencies. Animal studies have suggested that being smarter can actually be bad for animals...and it's not always an advantage for humans either. There should be a point here, but I'm a little fuzzy on what it is.

What Good Is Half A Machine?

One of the classic arguments against evolution by natural selection is "what good is half an X?" where X is an eye, a wing or some other complex body part or system. Directly responding to the implicit challenge some researchers have been not just figuring out how X could have evolved, but actually evolving new complex machines (previously). The basic ideas are so simple that web versions (explanation and discussion) have been popping up.

Otoliths

The Orienting Stone. "A snowy white stone that gives shape to the universe: as it happens, we all carry within our skulls the vestige of such a thing, a kind of existentially reversed qibla (this one perspectival, the other metaphysical) that gives us our sense of being at the center of things, the sense that we are upright at the origin point of a three-dimensional space..."

Making Tracks

"We were looking for pretty animals that have eyes, are coloured, or glow in the dark; instead, the most interesting find was the organism that was blind, brainless, and completely covered in mud." Some of the oldest fossil records may need to be reconsidered: Dr. Mikhail Matz of the University of Texas has discovered Gromia Sphaerica, a species of protist, making tracks.... [more inside]

Darwin, extended

The "blind watchmaker" may not be as blind as we thought. A team of scientists at Princeton University discovers that organisms are not only evolving, they're evolving to evolve better, using a set of proteins to "steer the process of evolution toward improved fitness" by making tiny course corrections.

Victorians, eminent and otherwise

The Victorian Web is your one-stop resource for England in the Victorian era (1837-1901). The site is much too extensive to give but a flavor. It is divided into 20 categories, including Technology, Gender Matters, Economic Contexts, Authors, Political History, Theater and Popular Entertainment, Science and Genre and Technique. Here are a few examples of the articles inside: Inventions in Alice in Wonderland, The Role of the Victorian Army, Earth Yenneps: Victorian Back Slang (and a glossary of same), Algernon Charles Swinburne and the Philosophy of Androgyny, Hermaphrodeity, and Victorian Sexual Mores, Evolution, progress and natural laws and, of course, Queen Victoria.

Natural selection observed in a lab

In the 1980s, Richard Lenski hypothesized that his research team should be able to watch random mutations and natural selection taking place in a lab by observing a bacteria population over many generations. In 1988, beginning with a single bacterium, he started several replicate colonies. Recently, after 33,127 generations, his team has observed natural selection.

3 to 10 classroom hours

16% of US science teachers believe human beings have been created by God within the last 10,000 years. 25% of science teachers spend some time teaching about creationism or intelligent design. 12.5% teach it as a "valid, scientific alternative to Darwinian explanations for the origin of species". 2% say they do not cover evolution at all. Teachers who have taken more science courses themselves devote more time to evolution - "This may be because better-prepared teachers are more confident in dealing with students' questions about a sensitive subject."

Is life on Mars a good sign for us?

The "Great Filter" is a hypothetical barrier to explain why civilisations are so unlikely to progress to the point of inter-stellar colonisation that we have not encountered any in 40 years of looking. Maybe humanity has already negotiated the filter - as some massive evolutionary improbability - or perhaps it lies in our future as an almost-certain threat to our existence? We should hold our breath as we look for evidence of life on Mars.

Jerry Fodor, on Why Pigs Don't Have Wings

Rutgers professor of philosophy Jerry Fodor created a bit of a stir last October when he wrote an article for the London Review of Books arguing that natural selection may not be such a great theory after all, and that a "major revision of evolutionary theory... is in the offing." Not many fellow philosophers and academics agree, it seems. Fodor responds to his critics here and here. Six months later, it's still not entirely clear whether his argument is, as Justin E.H. Smith put it, "irresponsible and stupid or so subtle that none of his adversaries, defending a status quo interpretation of the theory of natural selection, have been able to get it yet."

"Big Bird says it's time to wake up..."

A new round of genetic tests has confirmed it: The 'big lizards' of our childhood fantasies were more likely 'big birds.' In fact, they probably even had feathers, and looked more like this than this. Mind blowing, I know, but I guess this demonstrates that, despite what some may think, science really doesn't have a problem admitting that it got something wrong when new evidence comes to light.

No Intelligence Allowed, indeed.

Ben Stein's Expelled: No Intelligence Allowed, a pro-Intelligent Design, anti-evolution polemic, arrived in theaters Friday to overwhelmingly negative reviews and anemic ticket sales. In response to the claims made in the film comes Expelled Exposed, a website which seeks to "show you why this movie is not a documentary at all, but anti-science propaganda aimed at creating the appearance of controversy where there is none."

Spinoza and Biology

Public concern over ecological damage inflicted by human activity has led to growing recognition of the general importance of issues relating to biological science. Unfortunately, the dispute between creationists and upholders of the theory of evolution tends to overshadow public discussion of other more pertinent matters. Specifically, there are significant but relatively unpublicized initiatives underway to promote holistic approaches to biology. The Nature Institute in New York is one such initiative...

Neanderthal-Human Babies

Any admixture would have to be driven by male Neanderthals. Two years ago we discussed morphological evidence of nontrivial interbreeding. Since then Neanderthal DNA has been examined for genetic support for this model of human evolution, largely contradicting the belief in Neanderthal contribution to modern humanity. Indeed any contribution from the Neanderthal gene pool to the evolution of modern humans might be very rare and indeed it appears that the best candidate gene thus (MC1R) far likely was a result of convergent evolution.
