A University of Chicago doctoral candidate has shown that the evolution of the flatfish was much more gradual than previously thought.
'Bad is good as a mating strategy' (NewScientist PDF | plain text). "Nice guys knew it, now two studies have confirmed it: bad boys get the most girls."

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.
What Is A Species? "To this day, scientists struggle with that question. A better definition can influence which animals make the endangered list."
The aquatic ancestry of elephants Scientists believe they have discovered why elephants have trunks - they used them as underwater snorkels. New research suggests that the animals evolved from mammals like the sea cow. [more inside]
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."
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.
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."

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.
You Walk Wrong. "It took 4 million years of evolution to perfect the human foot. But we’re wrecking it with every step we take." [Via]
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."
Suspending Life. "If almost every species on Earth was killed some 250 million years ago, how did our ancient ancestors survive and evolve into us?"
Biomimetics: Design by Nature. "Burs on a dog's coat led to the invention of Velcro. That's an example of biomimetics—the young science of adapting designs from nature to solve modern problems. Now it may be coming of age."
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...

Dinner With Darwin. Scientists from various disciplines weigh in on what kind of dinner conversation they envision themselves having with Charles Darwin. Via.
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.

Fears that malevolent aliens will tune into this week's broadcast of The Beatles' song "Across the Universe" have been voiced by scientists.

Humans are evolving more rapidly than in the distant past, according to a new study published in PNAS. "The massive growth of human populations has led to far more genetic mutations, and every mutation that is advantageous to people has a chance of being selected and driven toward fixation. We are more different genetically from people living 5,000 years ago than they were different from Neanderthals", says lead author John Hawks. [more inside]
Dinosaurs preach Young Earth creationism. "The Fossil Finders are a group of eight homeschooled children on a search for the [Biblical] truth on fossils." (This shorter excerpt cuts to the main argument, involving the discovery of flexible T. Rex tissue. Scientists remain interested in the find.) The video was produced by World's Biggest Dinosaurs, the people who now own the roadside landmark, Cabazon Dinosaurs -- and have turned it into a creation museum. [Previously]

Judgment Day: Intelligent Design on Trial. Tonight on NOVA, a documentary on the six-week trial of Kitzmiller v. Dover. [Full transcripts of trial] The court's decision [PDF] by Judge John E. Jones III, chastised the defense's dishonesty and the "breathtaking inanity" of the Dover School Board's policy. Eugenie Scott of the National Center for Science Education recounts the the trial here. According to Salon, the Discovery Institute is not quitting -- preferring now to "teach the controversy," as part of their ongoing attack on naturalism. [Previously 1 2]
Be a Music Faun Yourself. A sign of the popularity of this operation is that in big cities so-called Faun-Clubs are founded one after another, where entrance is only allowed with pointed ears. The reverberating success of this new look is supported by more and more celebrities with pointed ears, amongst whom we can find not only musicians, but, for example, models, as well. via

Ben Stein, actor, game show host, economist and White House speechwriter has embarked upon a heroic and, at times, shocking journey in the new documentary Expelled to confront the world’s top scientists, educators and philosophers, regarding their 'persecution' of the academics who support the non-science that is Intelligent Design. Richard Dawkins and PZ Myers amongst others claim they were duped into appearing in the film believing it to be a film that was to be titled Crossroads (no not that Crossroads, nor this one) that would be a debate about creationism versus Darwinism. No wonder Ferris took a day off from school with this guy as his teacher (NSFW).
"From a review of the anthropological and evolutionary literatures [Edge.org]... there were three best candidates for being additional psychological foundations of morality [embedded video], beyond harm/care and fairness/justice. These three we label as ingroup/loyalty (which may have evolved from the long history of cross-group or sub-group competition...); authority/respect (which may have evolved from the long history of primate hierarchy, modified by cultural limitations on power and bullying...), and purity/sanctity, which may be a much more recent system, growing out of the uniquely human emotion of disgust, which seems to give people feelings that some ways of living and acting are higher, more noble, and less carnal than others.

Darwin's Deadly Legacy illustrates how Charles Darwin caused the Holocaust. This documentary, from the late Dr. James Kennedy and his Coral Ridge Ministries, features not only rare, Bigfoot-esque glimpses of the notoriously camera-shy Ann Coulter, but also Francis Collins, the head of the Human Genome Project. Of course, Dr. Collins hates everything about the documentary and claims that his footage was simply spliced in under false pretenses, and even Michael Behe distances himself from the entire production, disagreeing as he does with its central tenets. Oh, and the ADL is pissed, but when aren't they? Anyway, not even arch-conservative websites with "We Need Alan Keyes For President" interstitial ads think the documentary is worth very much. And it seems that Hitler himself had a grand old time pimping out Christianity and denying that we came from apes. (More, more.) So watch the fucking trailer and learn yourself some history.
