Evolution Extravaganza

It's everything evolution in the science section of the New York Times. A lead article focuses on the combination of evolutionary and developmental biology ("evo-devo") and findings that a relatively small number of genes can give rise to tremendous difference in an organism's form. If you're looking for more, here's a video on the growth of the evo-devo field, and this essay written by scientist Douglas Erwin says some researchers are calling for an "upgrade" to Darwin.

This article profiles Richard Lenski, the scientist known for his collection of 40,000 generations of E. coli and the evolutionary studies that that has enabled.

Another article checks into the evolution that's taken place in human DNA since the migration from Africa -- something that has helped scientists understand the path humans took, as well as the changes that have occurred within them. And this story looks into the elucidation of the human "family tree" through the studies of DNA.
