A new study in Science reveals that seals and sea lions have independently evolved brain structures remarkably similar to humans and songbirds, enabling volitional vocal control and learned sound production.

A new fossil from southern China reveals that a meter-long bony fish from 425 million years ago had unique clusters of spiky teeth on soft tissue 'cushions' — a jaw design never seen before.

A Science study reveals that unrelated animal species independently evolved nearly identical molecular mimics of the pain-causing peptide bradykinin as a defensive weapon.

A new study reveals the human chin is not an adaptation but a byproduct of evolutionary changes to our face, solving a century-old anthropological mystery.
