The study of experimental evolution in Escherichia coli has provided unprecedented insights into the mechanisms of adaptive mutations, elucidating how populations diverge and optimise their fitness ...

Scientists report adaptive divergence in cryptic color pattern is underlain by two distinct, complex chromosomal rearrangements, where millions of bases of DNA were flipped backwards and moved from ...

“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 ...
