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 ...

“The ubiquity of adaptive variation both within and between species means that a more comprehensive theory of molecular evolution must be sought,” Kern and Hahn wrote in their recent article. Matthew ...

A significant study has mapped the genetic complexity of Populus cathayana, an ecologically and economically valuable poplar species. By creating a detailed genome assembly and analyzing genetic ...

A large-scale population genomic study has shed new light on the evolutionary and domestication history of the button ...

Researchers have significantly expanded the catalogue of known human genetic variation. The resulting datasets, shared in two back-to-back publications in the journal Nature, constitute what may be ...

Researchers at the University of Maine are theorizing that human beings may be in the midst of a major evolutionary shift—driven not by genes, but by culture. "Human evolution seems to be changing ...

Humans were isolated in southern Africa for about 100,000 years, which caused them to "fall outside the range of genetic variation" seen in modern-day people, a new genetic study reveals. The finding ...
