It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Bioacoustics is a cross-disciplinary science that combines biology and acoustics. Usually it refers to the investigation of sound production, dispersion and reception in animals (including humans). [1] This involves neurophysiological and anatomical basis of sound production and detection, and relation of acoustic signals to the medium they ...

Neoteny is found more in modern humans compared to other primates. [6] In progenesis or paedogenesis, sexual development is accelerated. [7] Both neoteny and progenesis result in paedomorphism[8] (as having the ...
