Understanding the material basis of adaptive evolution has been a central goal in biology dating back to at least the time of Darwin. One focus of current debates is whether adaptive evolution relies ...

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 ...

A study published in Nature Ecology & Evolution reveals a surprising evolutionary insight: sometimes, losing genes rather than gaining them can help bacterial pathogens survive and thrive. The study ...

A new study reveals the surprisingly convergent evolution in the inner ear of mammals. An international research team showed that a group of highly divergent mammals known as Afrotheria and distantly ...

In Lake Malawi, Africa, fish known as cichlids have been evolving astonishingly fast—the lake hosts at least 800 species of them. Researchers who sequenced the genomes of these fish found that ...
