Researchers found genetic differences that likely resulted from humans killing aggressive bears, leaving docile individuals ...

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, ...

Amphidromous fish – which migrate between freshwater streams and the sea – can move between habitats thanks to ocean currents. Since island streams are generally small and vulnerable to human impact, ...

Trout living in rivers polluted by metal from old mines across the British Isles are genetically 'isolated' from other trout, new research shows. Trout living in rivers polluted by metal from old ...

GANSBAAI, SOUTH AFRICA - OCTOBER 19: A Great White Shark is attracted by a lure on the 'Shark Lady Adventure Tour' on October 19, 2009 in Gansbaai, South Africa. The lure, usually a tuna head, is ...

A groundbreaking study published in Nature Ecology & Evolution unveils a fascinating aspect of human prehistory, showing that ancient populations in Papua New Guinea were remarkably isolated from each ...

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 ...

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 ...

In a DNA sequence, an individual carries two copies of the genetic material – one from the mother, one from father. If one is damaged, the other copy is used. A combined effort of scientists and the ...
