New research has highlighted a fascinating link between human outer ears and the gills of ancient fish. Gene-editing ...

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 ...

This made us wonder whether the cartilaginous outer ear may also have arisen from some ancestral fish structure.” The first clue toward cracking this mystery was the team’s discovery that gills and ...
