The genomic landscape of rapid repeated evolutionary adaptation to toxic pollution in wild fish
Description: Many organisms have evolved tolerance to natural and human-generated toxins. The authors of this paper performed a genomic analysis of killifish, geographically separate and independent populations of which have adapted recently to severe pollution. Sequencing multiple sensitive and resistant populations revealed signals of selective sweeps for variants that may confer tolerance to toxins, some of which were shared between resistant populations. Thus, high genetic diversity in killifish seems to allow selection to act on existing variation, driving rapid adaptation to selective forces such as pollution. [Source: Science / AAAS]
