New research challenges long-standing assumptions about human evolution, revealing that natural selection has been more ...

A system once tied to DNA organization in cyanobacteria has evolved into a structure that shapes the cell itself. This shift ...

Scientists analyze 22,000 genomes documenting hundreds of genetic changes due to natural selection over the past 10,000 years ...

The whole world could soon be seeing red. Instead of being the punchline, redheads will have the last laugh, as a new study ...

Scientists have uncovered surprising clues hidden deep in human DNA, and the findings are forcing experts to rethink a ...

The work demonstrates the power of ancient DNA to illuminate human biology and medicine in addition to history. A massive ...

When Charles Darwin first proposed how evolution works in 1859, it seemed plausible. Tiny changes stack up over time, eventually leading a species to become something entirely different. Aside from ...

Cyanobacteria—ancient microbes that oxygenated Earth and made complex life possible—are still revealing surprises billions of ...

Ancient DNA reveals how farming accelerated human evolution, driving genetic changes over the past 10,000 years.

Over the past 10,000 years, evolution in West Eurasia has selected for light skin, red hair and resistance to HIV in humans, ...

Evolution works over millennia. Climate change is moving far faster. That mismatch is killing some of the planet's most vital ecosystems, from California's towering redwoods to the seagrass meadows ...
