Fish represent one of the most diverse groups of vertebrates, exhibiting a wide array of physiological adaptations that have enabled them to colonise nearly every aquatic habitat on Earth. Central to ...

A new study published in Science Advances explores the unique evolutionary processes among certain genes in certain fish species that allowed them to develop electric organs (think: the electric eel).

A new study explains how small genetic changes enabled electric fish to evolve electric organs. The finding might also help scientists pinpoint the genetic mutations behind some human diseases.

Scientists show the extraordinary diversity of cichlid fish in Africa’s Lake Victoria was made possible by ‘genetic recycling’ - repeated cycles of new species appearing and rapidly adapting to ...

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 ...

Migratory birds, sea turtles and salmon have something in common: every year, they return to their birthplaces to reproduce. A study now published in the journal Science Advances shows that Atlantic ...
