Studies have suggested that genes under strong sexual selection tend to evolve rapidly, particularly those associated with ...

The study showed that populations don’t lose their “evolvability,” even if conditions remain the same for many generations.

Scientists discovered humans descended from two ancient populations, not one. These groups split 1.5 million years ago.

A longstanding question in evolutionary biology is how sexual selection influences how entire genomes develop. Sexual selection is where individuals ...

Yet despite this growing interest in consciousness, the million-dollar question remains: does the stoned ape theory have any ...

Evolution is the process of heritable change ... which can occur through mechanisms including natural selection, sexual selection and genetic drift. The 2005 finding of cells and blood vessels ...

They have done nothing less than witness Darwin's theory of evolution unfold before their eyes. That would have stunned Darwin, who thought natural selection operated over vast periods of time and ...

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.

Feb. 27, 2025 — Researchers examined dozens of bird species in museum collections looking for differences in the feathers and bodies between birds that can fly and birds that can't. They found ...

Absolute perfectionism is the belief that we ought to be perfect everywhere, all the time, and to everyone. Doing so is impossible, but a healthier version of perfectionism exists.

In March 1925, Tennessee became the first state in the country to ban the teaching of evolution in public school classrooms.

"Our history is far richer and more complex than we imagined," said human evolutionary geneticist Aylwyn Scally.
