An analysis of ancient and modern DNA suggests the extent of convergent evolution in different peoples around the world is ...

Humans and Neanderthals cozied up from time to time when they lived in the same areas tens of thousands of years ago. But we don’t know much about who got with whom, or why.

Life is precious, and many of us try to do everything “right” to live longer. We eat better, move more, avoid pollutants, guard our sleep, manage stress, and take supplements. The prevailing belief is ...

A new study reveals that habitat fragmentation can lead to sudden "tipping points" where a species' genetic health ...

Scientists have discovered a potential path out of devastating genetic bottlenecks that could help these Australian animals, ...

Koalas’ population comeback may be doing more than boosting numbers—it could also be rebuilding their lost genetic diversity.

Smithsonian researcher Sarah Johnson studies bison specimens to understand how the species’s genetic diversity changed after its decline ...

Interbreeding Direction Solves Neanderthal X Chromosome Mystery Homo sapiens females unions with Neanderthal males explain X chromosome DNA gap ...

Scientists have uncovered 6,000-year-old human remains in Colombia whose genetic code matches no other known population, ancient or modern.

The researchers also found that Neanderthals had far more human DNA on their X chromosomes than expected. This confirms the theory that Neanderthal men had more involvement with human women than the ...

The pairings were more often female humans with male Neanderthals. How exactly this happened remains a huge question mark. Did human women venture into Neanderthal populations, or were the Neanderthal ...
