TimeTree is a public knowledge-base for information on the evolutionary timescale of life. A search utility allows exploration of the thousands of divergence times among organisms in the published literature. A tree-based (hierarchical) system is used to identify all published molecular time estimates bearing on the divergence of two chosen taxa, such as species, compute summary statistics, and present the results . . . For those interested in published summaries of relationships and divergence times of major groups of organisms (family level and above), see the authoritative synthesis The Timetree of Life.

Here are some examples to get you started: Humans and Chimpanzees diverged 6.3 MYA; Giraffes and Dolphins diverged 58.3 MYA; Cats and Mice diverged 95.2 MYA; and Dogs and Fleas diverged 777.8 MYA. [more inside]

On Friday, July 22, the Texas Board of Education voted 14-0 to support scientifically accurate high school biology textbook supplements, rejecting the proposed creationist materials. Instead of including such material, the education board voted to let Education Commissioner Robert Scott work with the publishing company Holt McDougal to find language that is factually correct and fits the standards adopted in 2009. "My goal would be to try to find some common ground," Scott said.

More than 300 heavily-annotated books from Charles Darwin's personal library have been digitized in a collaboration between Cambridge University, which holds the collection, and the Biodiversity Heritage Library, a project that has so far digitized nearly 50,000 titles from the natural sciences. And if you're looking for what Darwin wrote, rather than what he read, the University of Oklahoma has digitized the first edition of each of his 22 books.

A Mismeasured Mismeaurement of Man. Stephen Jay Gould's classic The Mismeasure of Man argues that 19th century scientist Samuel George Morton inflicted his own racial biases on his data to demonstrate that Caucasians had larger brains than other races. A new paper in the Public Library of Science: Biology debunks Gould's account by remeasuring the same skulls Morton used. Whatever biases Morton may have had, they are not reflected in the data.

Larry Gonick is a veteran American cartoonist best known for his delightful comic-book guides to science and history, many of which have previews online. Chief among them is his long-running Cartoon History of the Universe (later The Cartoon History of the Modern World), a sprawling multi-volume opus documenting everything from the Big Bang to the Bush administration. Published over the course of three decades, it takes a truly global view -- its time-traveling Professor thoroughly explores not only familiar topics like Rome and World War II but the oft-neglected stories of Asia and Africa, blending caricature and myth with careful scholarship (cited by fun illustrated bibliographies) and tackling even the most obscure events with intelligence and wit. This savvy satire carried over to Gonick's Zinn-by-way-of-Pogo chronicle The Cartoon History of the United States, along with a bevy of Cartoon Guides to other topics, including Genetics, Computer Science, Chemistry, Physics, Statistics, The Environment, and (yes!) Sex. Gonick has also maintained a few sideprojects, such as a webcomic look at Chinese invention, assorted math comics (previously), the Muse magazine mainstay Kokopelli & Co. (featuring the shenanigans of his "New Muses"), and more. See also these lengthy interview snippets, linked previously. Want more? Amazon links to the complete oeuvre inside! [more inside]

Big dust up about kin selection. Biologists E.O. Wilson, Martin Nowak, and Corina Tarnita publish a paper attacking kin selection, the idea that the reproductive success of a gene is influenced not only by its effects on its carrier, but also by its effects on related individuals (kin) carrying the same gene. 130 some odd other biologists respond. Richard Dawkins weighs in. Some talking bears offer a summary. [via]

Evolution Made Us All

Swimming around in a mixture of language and matter, humans occupy a particular evolutionary niche mediated by something we call 'consciousness'. To Professor Nicholas Humphrey we're made up of "soul dust": "a kind of theatre... an entertainment which we put on for ourselves inside our own heads." But just as that theatre is directed by the relationship between language and matter, it is also undermined by it. It all depends how you think it.

CreatureCast is a collaborative blog and podcast from evolutionary biologist Casey Dunn, who uses it as a teaching tool at the Dunn Lab at Brown University. The Lab investigates ways in which evolution has produced a diversity of life, and the blog includes neat, invertebrate zoology-related videos that may cover anything from "mating when you're stuck to a rock" to Flying with Squid to Multicellularity to Diving for Jellies.

Tibetans May Be Fastest Evolutionary Adapters Ever. "A group of scientists in China, Denmark and the U.S. recently documented the fastest genetic change observed in humans. According to their findings, Tibetan adaption to high altitude might have taken just 3,000 years. That's a flash, in terms of evolutionary time, but it's one that's in dispute."

An article in the June issue of Proceedings of the Royal Society of the Biological Sciences finds that "differences in reproductive strategies are driving individuals' different views on recreational drugs": namely, that views on sexual promiscuity are more closely related to views on recreational drug use than religion, political affiliation or other predictors. The study suggests attitudes against recreational drug use are an evolutionary attempt to promote reproductive stability.

Carl Zimmer on the duck's incredibly long, corkscrew-shaped, ballistic penis.
My tale is rich with deep scientific significance, resplendent with surprising insights into how evolution works, far beyond the banalities of “survival of the fittest,” off in a realm of life where sexual selection and sexual conflict work like a pair sculptors drunk on absinthe, transforming biology into forms unimaginable. But this story is also accompanied with video. High-definition, slow-motion duck sex video. And I would imagine that the sight of spiral-shaped penises inflating in less than a third of second might be considered in some quarters to be not exactly safe for work. It’s certainly not appropriate for ducklings.

Why is the penis shaped like that? [T]he human penis is actually an impressive “tool” in the truest sense of the word, one manufactured by nature over hundreds of thousands of years of human evolution. You may be surprised to discover just how highly specialized a tool it is. Furthermore, you’d be amazed at what its appearance can tell us about the nature of our sexuality.

Why would an evolutionary biologist study words? It turns out there is an astonishing parallel between the evolution of words in a lexicon and the evolution of genes in an organism. The word two, for example, has been around much longer than most, and will likely be with us for millennia, whereas the comparatively rare and recent word dirty has undergone many mutations, and will probably be extinct in a few hundred years. Professor Mark Pagel, an evolutionary biologist at the University of Reading, UK, tells us why on the Canadian Broadcasting Corporation's program As It Happens.

Although the evolution of the eye is often pointed to by evolution's skeptics as evidence of design, biologists have been quick to point out evidence to the contrary. Today, Julian Partridge of Bristol University's Ecology of Vision Research Unit has brought to light evidence of a Pacific fish that has evolved biological mirrors for navigating murky water.

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.
