The outer ears that sit on the sides of your head share an unexpected genetic heritage with the gills of fish. According to ...

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 ...

A collaborative team of scientists recently found that there is no physiological evidence supporting a leading theory -- which involves the surface area of fish gills -- as to why many fish species ...

Evolution is a master recycler. It often uses old structures (or ancient genes) for new jobs. The mammalian ear is a perfect example. Over the eons, the jawbones of our fish ancestors became three ...
