One of the biggest mysteries of evolution is how species first developed complex vision. Jellyfish are helping scientists solve this puzzle, as the group has independently evolved eyes at least nine ...

While this scenario sounds apocalyptic for us, it's run-of-the-mill for blind Mexican cavefish (Astyanax mexicanus) as ...

The study was published in the Proceedings of the National Academy of Sciences (PNAS) by palaeontologists at the University ...

A fish thought to be evolution’s time capsule just surprised scientists. A detailed dissection of the coelacanth — a 400-million-year-old species often called a “living fossil” — revealed that key ...

A study published in the Nature journal alters how the evolution of fish has been historically understood. Fossilized fish and other sea creatures have often been pivotal in new scientific discoveries ...

Researchers in Alberta uncovered a fossil fish that rewrites the evolutionary history of otophysans, which today dominate freshwater ecosystems. The new species, Acronichthys maccognoi, shows early ...
