The evolution of the mammalian ear and the comparative research with the ears of humans.

Introduction

In order to understand the evolution of the human ear, we must trace its origins and comparison in the mammalian lineage. Therefore, to identify the changes in the hearing capacity of the evolution of humans, a comparison had to be made to the evolution of other mammals (Masterton et al. 1968). It was concluded that high frequency hearing (>32 kHz) is a trait that characterizes mammals. This was due to the short distance of their ears, and the result for the selective pressure to know the accurate source of brief sounds. Sounds with a low frequency (<1 kHz) is a trait that characterizes all mammals, especially humans (Masterton et al. 1968).

The Eutherian Mammalian Ear

Regarding the evolution of the eutherian mammalian ear, Manley (2017) distinguished that during the Paleozoic era (>250 million years ago), the synapsids were no longer under the stem...
