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.
Natural selection reduced the variation on human X chromosomes in populations with the most Neandertal and Denisovan mixture. It may have been meiotic drive.
New DNA evidence is revealing the genetic relationships of ancient groups from southern China, showing how they were connected to living people across the region.
A child's skull from Mount Carmel gives an occasion to look at the history of ideas about population mixture.
Describing the results of genomic work by Michael Westbury and collaborators, including ancient hyena genomes from Eurasia and North America.
An analysis by Melissa Hubisz and coworkers finds that mtDNA is not all that Neandertals received from our African ancestors
Examining a paper that uses Alu insertions as a probe for ancient reticulation in the papionin tree of relationships.
A quote from Loren Eiseley, one of the best known writers about anthropology and human origins.
Should we be surprised if Neandertals, Denisovans, and modern humans didn’t form stable hybrid zones?
A geneticist asks why we don't see more persisting hybrid populations, and I find an answer in the theory of population source-sink dynamics.
Addressing a widespread misconception about what geneticists are really measuring when they look at population mixture.
