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 ...

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

Have you ever wondered why our ears look the way they do? That soft, curved shape we rarely think twice about might actually carry a hidden story– one that traces all the way back to life under the ...

When you and I take a deep breath, we pull air into our lungs. That’s because humans are mammals. But fish aren’t mammals. They usually don’t breathe air. They usually don’t have lungs. That’s what I ...

Fish induce production of a particular antibody in their gills in response to pathogen exposure, researchers report at the conclusion of work that could lead to improved fish vaccines for aquaculture.

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 ...

The middle ear of humans evolved from fish gills, according to a study of a 438 million-year-old fossil fish brain. Scientists discovered the fossil of the braincase of a Shuyu fish. Despite its skull ...
