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 ...

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 ...

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 ...
