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 ...

An ancient, well-preserved fish brain analyzed recently by University of Michigan scientists could unlock new discoveries about evolution and the formation of fossils. The brain, which the university ...

A recent study has uncovered the surprising evolutionary origin of the mammalian outer ear, linking it to the gills of ancient fish and marine invertebrates. The research reveals that both structures ...

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 ...

Antibodies—proteins that are produced by our immune system to protect us—are crucial for recognizing and getting rid of unwanted substances, or antigens, in our body. Although their role is universal, ...

Humans' outer ears may have evolved from the gills of prehistoric fish, a new study finds. Gene-editing experiments indicate ...

Before animals crawled out of the sea and spread onto land, the appearance of jaws marked a significant time in the development of nearly all living vertebrates, including humans. A scientist is shown ...

Antarctic notothenioids represent a remarkable evolutionary radiation of fishes that have flourished in the extreme cold of the Southern Ocean. Their unique adaptations — including specialised ...
