The Trojan male method relies on genetics to collapse invasive populations. Unlike wild males that have one X and one Y chromosome, these specially bred fish have two Y chromosomes.

Herring from different parts of the Baltic Sea belong to distinct populations genetically adapted to local differences in salinity and temperature. However, these populations can also mix with each ...

In Lake Malawi, hundreds of species of cichlid fish have evolved with astonishing speed, offering scientists a rare opportunity to study how biodiversity arises.

The Amazon molly is an evolutionary enigma: an all-female fish that reproduces by cloning itself. Because it doesn’t mix its DNA with a mate’s, Darwinian logic holds that harmful mutations should pile ...
