In natural populations, the mechanisms of evolution do not act in isolation. This is crucially important to conservation geneticists, who grapple with the implications of these evolutionary processes ...

ISLAND LIFE is famously idyllic, but it’s long been known that islanders tend to experience disproportionately high rates of some rare genetically transmitted diseases. Faroe islanders, for example, ...

I have spent years covering discoveries that nudge our origin story around the edges, but the sequencing of DNA from one of the very last Neanderthals does something different: it rewrites the center ...

The Y chromosome is unlike other chromosomes in the human genome. It does not regularly recombine with a matching partner, making it genetically isolated. Over evolutionary time, this isolation has ...

Geographical barriers and cultural differences can prevent people from mingling with their neighbors, leading to genetic isolation — and the phenomenon is more common than most people think. When you ...

New research in Indonesia shows that small islands, often considered extinction hotspots, can act as crucial refuges for rare mammals like the anoa and babirusa, which face severe threats from ...
