New assessments detail severe genetic diversity losses in cheetahs, North Atlantic right whales, and vaquitas, underscoring risks to fertility, disease resistance, and population resilience. By ...

A new study sheds light on one of the great enigmas of microbiology: why only certain strains of common bacteria become pandemic pathogens. The work, published in Proceedings of the National Academy ...

Newfound evidence reveals that the upsurge of the exotic Nile perch in Lake Victoria had long-lasting effects on the genetic diversity of various local cichlid species, report scientists from Tokyo ...

Pre-Neanderthals once roamed Eurasia around 500,000 years to 250,000 years ago. During the end of that period, pre-Neanderthals slowly began the evolutionary process into early Neanderthals, which ...
