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 ...

Human evolution’s biggest mystery, which emerged 15 years ago from a 60,000-year-old pinkie finger bone, finally started to unravel in 2025.

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

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

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, ...

In tropical climates, lizards are everywhere. It can be a bit wild to see, and they come in all shapes and sizes. They seem a tad superfluous in such large varieties leaving one to wonder, what ...

Important, previously unrecognized genetic changes common to all ancient and modern Homo sapiens spread in Africa more than 300,000 years ago, a new study finds. After that, the same investigation ...

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

Human evolution may no longer be driven primarily by genetics, according to a new theory by researchers at the University of Maine which claims that cultural systems are now shaping the way humans ...

The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...
