Is it time to put natural selection in its place? Jello Biafra once famously wrote that "If evolution is outlawed, only outlaws will evolve." But while it likely comes as no surprise to specialists working in the field or to those who've been following developments in evolutionary biology closely, there's an emerging view among experts that Darwin's view of natural selection as the primary driver of speciation and evolutionary change may be incorrect or at least drastically overstated. It's long been understood that non-adaptive evolutionary mechanisms like "genetic drift" and random mutation also play non-trivial roles in evolutionary processes, but a recent study (link to abstract with full-text PDF available) casts new doubts on the primary role of natural selection, finding that "Neutral models, in which genetic change arises through random variation without fitness differences have proven remarkably successful in describing observed patterns of biodiversity."

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.
The life and times of Tom Eisner, father of chemical ecology, photographer, musician and champion of environmental and human rights
Thomas Eisner, a Cornell biologist best known for his extensive work (PDF) with chemical ecology, passed away on Friday, March 25th, 2011. Eisner was more than a "bug guy," he was one of the "original guiding lights" in the study of chemical interactions of organisms, most often focusing on insects. He also was a photographer, pianist and occasional conductor (PDF), and conservation activist. More on his fascinating life inside. [more inside]
Misunderstanding Darwin: Natural selection’s secular critics get it wrong. Ned Block and Philip Kitcher review Jerry Fodor's (previously) and Massimo Piattelli-Palmarini's book What Darwin Got Wrong. Fodor and Piattelli-Palmarini respond: “Misunderstanding Darwin”: An Exchange.
Darwin the abolitionist. "The theory of evolution is regarded as a triumph of disinterested scientific reason. Yet, on the 150th anniversary of On the Origin of Species, new research reveals that Darwin was driven to the idea of common descent by a great moral cause." [Via]

A University of Chicago doctoral candidate has shown that the evolution of the flatfish was much more gradual than previously thought.

Darwin's Surprise. "There may be no biological process more complicated than the relationships that viruses have with their hosts. Could it be that their persistence made it possible for humans to thrive?" [Via Disinformation.]
