Scientists have come closer to finding the common ancestor of all Earth life. The last common universal ancestor (LUCA) is an idea that goes back to Charles Darwin's On the Origin of Species and whose existence is supported by the fact that all Earth life is based on DNA. But the tantalizing search is getting closer, primarily based on the question, "Which features of the archaea, bacteria and eukaryotes can be traced back to their common ancestor, LUCA?"
How to hatch a dinosaur: 'So making a chicken egg hatch a baby dinosaur should really just be an issue of erasing what evolution has done to make a chicken. Every cell of a turkey carries the blueprints for making a tyrannosaurus, but the way the plans get read changes over time as the species evolves.' [via]

As an evangelical Christian, Rachel Held Evans often heard about the importance of practicing "biblical womanhood," but she didn't quite know what that meant. Everyone she asked seemed to have a different definition. Evans decided to embark on a quest to figure out how to be a woman by the Bible's standards. For one year, she has followed every rule in the Old and New Testaments. (FAQ) Her project is set to end today. [more inside]
Collective violence, extending from riots to warfare, presents a challenge to our ordinary understanding of free will. Actions that would rarely be taken by an individual on their own seem to be embraced when supported by a larger group. This can occur in societies ranging from the communist regime of Soviet Russia to the capitalist free market of modern day England. Given this commonality, perhaps the collective violence of a riot can be best understood as a biological event in which evolved cognitive responses encounter a unique environmental threat. And if that is the case, do individuals caught up in such incidents have any choice in the matter?Freedom to Riot: an evolutionary perspective on collective violence.

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]

Ants are one of the most abundant groups on earth, but, curiously, not a lot of things eat them. Yes, there are anteaters (who also eat a lot of termites), and some lizards specialize on ants, but the little critters are full of noxious chemicals and pheromones that put them way down on the list of predators’ preferred foodstuffs. Because of this, many other insects and arthropods have evolved to mimic ants, taking advantage of the aversion of predators to anything antlike. These mimics are called myrmecomorphs, and they’re the subject of a really nice eponymous feature in this week’s Current Biology.[via]

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]

Consider this animal, the newest fossil discovery from Jianni Liu in China. She calls it "the walking cactus." We have grasses and flowers and beetles in more varieties than you can imagine, and yet, in some deep architectural way, the developmental paths were set way back then, 500 million years ago. The Walking Cactus is just another souvenir of that crazy moment.

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.
Watch your computer design a 2 dimensional car. What happens when you give a computer, instead of a predefined function to run, a set of parameters, a goal, and the ability to mutate those parameters? You get a genetic algorithm. At its core, genetic algorithms can best be described as Darwinian evolution of computer functions. Is it better to use a streamlined, wide-wheel-base motorcycle to cross terrain, or something that looks like a cross between a fish and a tank? This simplistic simulation shows just what's going to cause the rise of Skynet.
