The outer portion of the external ear reflects sound towards the ear canal. Once in the ear canal, the pressure waves are aligned so they strike the ear drum at right angles. The reflection of sounds ...
Scientists have traced the evolutionary origin of humans' outer ears to the gills of ancient fish through a series of gene-editing experiments.
A recent study has uncovered the surprising evolutionary origin of the mammalian outer ear ... the elastic cartilage of gills moved to the ear canal, which the scientists demonstrated in a ...
