As fish in different parts of the world adapted to live in fresh water, the same sites in the genome were changed time and again. Three-spine sticklebacks aren't as pretty as many aquarium fish, and ...

Theories of evolution were developed without an understanding of genetics, and while our ability to study genes has advanced tremendously, those advancements have happened only in the past few decades ...

Researchers have identified the genetic basis of rapid adaptation using a native fish species. They compared threespine stickleback fish from different habitats in the Lake Constance region. Their ...

SEATTLE – Evolution is supposed to inch forward over eons, but sometimes, at least in the case of a little fish called the threespine stickleback, the process can go in relative warp-speed reverse, ...

A group of researchers from the University of Helsinki used novel and powerful methods to disentangle the patterns of parallel evolution of freshwater three-spined sticklebacks at different geographic ...

The three-spined stickleback (Gasterosteus aculeatus) is a teleost fish that has undergone rapid adaptive evolution and speciation within the last 15,000 years. The benthic species has greatly reduced ...
