The cichlid fish of Africa's Great Lakes have formed new species more rapidly than any other group of vertebrates. A new study shows that the ease with which these fish can develop a biological ...

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 ...

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 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.

Why do you think giraffes have such long necks? It’s a question that has perplexed scientists for years. Do you think giraffes have long necks to reach food in high places? Maybe you are onto ...

The coelacanth is known as a "living fossil" because its anatomy has changed little in the last 65 million years. Despite being one of the most studied fish in history, it continues to reveal new ...

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 ...

An international, multi-university research team, including scientists from Columbus State University, has unearthed a crucial new piece of the puzzle in the evolution of sharks. A recent study ...

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, ...
