Why are humans evolving to lack their wisdom teeth?
The frequency of M3 agenesis varies greatly among human populations. It may have to do with agricultural diets, but anthropologists aren't sure.

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