Evidence of widespread straying in Prince William Sound is fueling calls for the Alaska Board of Fisheries to limit hatchery ...

The tiny Amazon molly (Poecilia formosa) has always fascinated researchers because, according to the rules of evolution, it shouldn't have survived as a species, let alone thrive as a species for over ...

The Amazon molly reproduces without sex. A genomic copy-and-paste trick called gene conversion may explain how it avoids evolutionary meltdown.

Amazon mollies don't need a man, and never will. A new study finds they can purge and repair genetic mutations that would otherwise plague a self-cloning species.

Skeletal development in fish is a multifaceted process involving a finely tuned interplay between genetic determinants, nutritional status and environmental conditions. Recent advances have elucidated ...
