Human evolution’s biggest mystery, which emerged 15 years ago from a 60,000-year-old pinkie finger bone, finally started to ...

A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...

Tiny genetic variations between humans, Neanderthals and Denisovans might not be all they were cracked up to be.

Charles Darwin's theory of evolution generated scientific debate and discussion not only in Darwin's own time, but for decades afterward. In the latter part of the nineteenth century and the until the ...

A study in fruit flies suggests an internal genomic arms race may be driving rapid evolution in proteins that still perform an essential, unchanging job: protecting chromosome ends.

Evolution is slow, but with the right experimental set-up—and enough time to spare—you can watch nature do its methodical ...

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe. Using advanced analysis based ...

Woodrats weigh less than half a pound but can survive venomous rattlesnake bites that would hospitalize, or even kill, a full ...

MPN-BP transformation is driven by sequential mutations disrupting genomic stability, with TP53 mutations being strong predictors of progression. TP53 mutations confer a selective growth advantage, ...

How did horses become some of the greatest athletes in the animal kingdom? Researchers at Johns Hopkins Medicine may have found the answer, pinpointing a genetic mutation and evolutionary process that ...
