Researchers have traced cell origins critical to vertebrate evolution by studying a group of primitive, bloodsucking fish called lampreys. When you purchase through links on our site, we may earn an ...

The same regulatory landscape which influences the development of fingers is present in fish, despite their distinct lack of digits. When researchers used CRISPR (a common gene editing tool) to fiddle ...

A living fossil fish just proved we've misunderstood a major chapter in the story of evolution. For decades, the coelacanth — an ancient fish species that first appeared 400 million years ago — was ...

The sea lamprey looks like it’s from another planet, but this ancient creature has a surprising amount in common with humans ...

A tiny fish fossil found far inland in Canada reveals new insight into the evolution of catfish, carp, and 2/3 of all ...

Yara Haridy, an evolutionary biologist at the University of Chicago, likes to stun people by telling them that our skeletons evolved from a jawless fish. "Much of what we have today has been around ...

A team of researchers at the Georgia Institute of Technology have zeroed in on an amphibious fish species to better understand the evolutionary pressures that molded blinking in land-dwelling ...

A trade-off between tooth size and jaw mobility has restricted fish evolution, Nick Peoples at the University of California Davis, US, and colleagues report in the open-access journal PLOS Biology.

For 150 million years, gars—a group commonly derided as “trash fish”—have mostly stayed the same, a rare consistency not even seen in sharks, a new study says. A longnose gar swims through Florida's ...

It's not what you do, it's how readily you do it. Rapid evolutionary change might have more to do with how easily a key innovation can be gained or lost rather than with the innovation itself, ...
