natural selection
How much of human evolution was due to polygenic adaptation?
This has been an eventful week for those of us who study the dynamics of recent selection in humans. The most significant event was the publication of a paper describing genetic analysis of a long selection experiment in Drosophila. Although the experiment differs from most natural instances of selection in

Human evolution stopping? Wrong, wrong, wrong.
I look into arguments by the geneticist Steve Jones that human evolution has stopped. It hasn't.

Our new paper on why human evolution accelerated
I run through our 2007 work on evidence for recent natural selection across the human genome.
