“neoteny”的概念、定义、翻译、参考文献-科学参考

neoteny

Biology

The retention of the juvenile body form, or particular features of it, in a mature animal. For example, the axolotl, a salamander, retains the gills of the larva in the adult. Neoteny is thought to have been an important mechanism in the evolution of certain groups, such as humans, who are believed to have developed from the juvenile forms of apes. Most strikingly, adult humans retain a skull shape that closely resembles that of an infant, giving a large brain case, whereas in the closely related chimpanzees, the skull undergoes a dramatic change of shape into adulthood, with a much smaller brain case. See also heterochrony.

Geology and Earth Sciences

Slowing down of bodily development, so that sexual maturity is achieved while the organism still looks like a juvenile; this leads to paedomorphosis. Since the juvenile stages of many organisms are less specialized than the corresponding adult stages, such shifts allow the organisms concerned to switch to new evolutionary pathways. The word comes from the Greek neos (meaning ‘youthful’). Some features of human evolution have been ascribed to neoteny.
