Human Middle Ear Evolved From Fish Gills, Study Suggests

According to a new study of a 438-million-year-old fossilized fish brain, the middle ear of humans evolved from fish. 'Newsweek' reports that scientists managed to recreate seven virtual casts of the fossilized braincase of an ancient Shuyu fish. The team from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) studied the spiracle, slits behind the eyes which allow some species to breathe.
