A new study of African genetic variation yields a more accurate picture of the genetic exchanges between ancient Africans and Neandertals 250,000 years ago.
An intriguing new study tries to tabulate the ages of genetic variants associated with human phenotypes, but its claims about recent brain evolution may not pan out.
Even with whole genomes, scientists can't say very precisely what pattern of skin, hair, and eye pigmentation was in ancient populations like the Neandertals.
Natural selection reduced the variation on human X chromosomes in populations with the most Neandertal and Denisovan mixture. It may have been meiotic drive.
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
I look into arguments by the geneticist Steve Jones that human evolution has stopped. It hasn't.
I run through our 2007 work on evidence for recent natural selection across the human genome.
