WASHINGTON (Reuters) - While people and other vertebrates are color blind in dim light, some deep-sea fish may possess keen color vision to thrive in the near total darkness of their extreme ...

Despite the vast evolutionary gulf between humans and the three-spined stickleback fish, the two species have adopted a common genetic strategy to acquire the skin pigmentation that helps each species ...

Long-running evolutionary biology research on fish populations by UC Riverside scientist David Reznick has yielded new findings into how fish keep their gene pools healthy. Female fish tend to choose ...

A fisherman in Minnesota has caught a sunfish with a rare genetic mutation that makes its skin golden. Terry Nelson was fishing for sunfish and crappies on Lindstrom Lake, in Chisago County, when he ...

With help from a common aquarium pet and a recently released online database of human genetic variation, a collaborative team of Penn State researchers has found what could be the most important skin ...

The genetic underpinnings of pigmentation and colour patterning in fish encompass a complex interplay of gene regulation, cell fate determination and evolutionary innovation. Neural crest cells, which ...

Astyanax mexicanus cave fish have adapted to an incredibly tough environment: chilly, pitch-dark caves that flood about once a year, providing brief feasts separated by long periods of starvation.

When humans began to migrate out of Africa about 100,000 years ago, their skin color gradually changed to adapt to their new environments. And when the last Ice Age ended about 10,000 years ago, ...
