A new paper by a team of researchers led by University of Notre Dame biologist Jeffrey Feder could herald an important shift in thinking about the genomics of speciation. Titled "Widespread genomic divergence during sympatric speciation," the paper appears in today's edition of the Proceedings of the National Academy of Sciences. The prevailing assumption among scientists about how the genomes of newly forming species should differ during the earliest stages of divergence with gene flow...

A genetic study of island lizards shows that even those that have been geographically isolated for many millions of years have not evolved into separate species as predicted by conventional evolutionary theory. Professor Roger Thorpe and colleagues Yann Surget-Groba and Helena Johansson, at Bangor University, UK, reveal their findings April 29 in the open-access journal PLoS Genetics. Since Darwin's study of the Galapagos Islands, archipelagos have played a central role in understanding how...

Feeding birds in winter is a most innocent human activity, but it can nonetheless have profound effects on the evolutionary future of a species, and those changes can be seen in the very near term. That's the conclusion of a report published online on December 3rd in Current Biology, a Cell Press publication, showing that what was once a single population of birds known as blackcaps has been split into two reproductively isolated groups in fewer than 30 generations, despite the fact that they...
