A study published in Nature Communications describes evolutionary changes in Neanderthal morphology through the analysis of ...
Middle ear appeared in amphibians ... As development progresses, the vesicle assumes the complicated shape of its adult form and is called the labyrinth. Labyrinth is filled with fluid endolymph.
In order to reduce these reflections and maximize the transfer of sound energy from the air filled environment to the fluid filled inner ear, land animals evolved external ears as sound collectors and ...
and Mercedes Conde-Valverde from the Cátedra de Otoacústica Evolutiva de HM Hospitales y la Universidad de Alcalá led a team of researchers who analyzed the semicircular canals — the fluid-filled ...
New research on the inner ear morphology of Neanderthals and their ancestors challenges the widely accepted theory that Neanderthals originated after an evolutionary event that implied the loss of ...
