Comparisons between historical and modern data reveal a consistent decline in genetic diversity,” said Frances Cassirer, IDFG ...

The researchers identified regions with Neandertal ancestry in over 300 individuals. They assessed sharing of segments, inferred gene flow, and looked at variation to identify candidates for positive ...

Gene flow — the movement of genetic material between populations — is a powerful evolutionary force that shapes biodiversity, adaptation, and even our own human history. From pollen drifting on the ...
