Caught in the act: Study probes evolution of California insect

A first-of-its-kind study this week suggests that the genomes of new species may evolve in a similar, repeatable fashion -- even in cases where populations are evolving in parallel at separate locations. Evolutionary biologists used a combination of ecological fieldwork and genomic assays to see how natural selection is playing out across the genome of a Southern California stick insect that is in the process of evolving into two unique species.http://feeds.sciencedaily.com/~r/sciencedaily/~3/8...
