متن کاملInterrogating 11 fast-evolving genes for signatures of recent positive selection in worldwide human populations.

Here, we identify genes showing signatures of ancestral positive selection in the human lineage and investigate whether some of those genes have been evolving adaptatively in extant human populations. Specifically, we compared more t...
