Engineering analysis of Thrinaxodon fossils uncovers unexpectedly advanced hearing in early mammal kin
One of the most important steps in the evolution of modern mammals was the development of highly sensitive hearing. The middle ear of mammals, with an eardrum and several small bones, allows us to ...
