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 ...

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 ...

Engineers at Cornell University have developed perforated, flexible panels modeled on fish gills that significantly improve heat transfer and chemical mixing in fluid environments. The work, led by ...

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 ...
