Human Ear Evolved From Gills Of Ancient Fish, New Report Says
It turns out the human ear got off to a fishy start. Literally. A fascinating new study reveals that the mammalian outer ear has its evolutionary roots in the gills of ancient fish. This surprising discovery sheds light on how structures can adapt over millions of years to serve entirely new
Mammalian outer ear traced back to ancient fish gills
The outer ear is unique to mammals, but its evolutionary origin has remained a mystery. According to a study published in Nature from the USC Stem Cell lab of Gage Crump, this intricate coil of cartilage has a surprisingly ancient origin in the gills of fishes and marine invertebrates.
Mammalian Outer Ear Has Its Origins in Fish Gills
