Bogin points out that Kollmann had intended the meaning to be "retaining youth", but had evidently confused the Greek teínein with the Latin tenere, which had the meaning he wanted, "to retain", so that the new word would mean "the retaining of youth (into adulthood)". [15] In 1926, Louis Bolk described neoteny as the major process in ...
Neoteny of the human body is indicated by glabrousness (hairless body). [3] Neoteny of the genitals is marked by the absence of a baculum (penis bone); [1] the presence of a hymen; [1] and the forward-facing vagina. [1]
Neotenic complex syndrome (NCS) is a syndrome that presents as an extreme form of developmental delay, with the defining characteristic being neoteny of the patient. It was named in 2017 by Dr. Richard F. Walker, who discovered several genes implicated in the syndrome.

Steven J. Gould discussed the presentation of neoteny with "terminal additions" in humans. [8] Neoteny is defined as the delayed or slowed development in humans when compared with their non-human primate counterparts. The "terminal additions" were extensions or reductions in the rate and scope of stages of development and growth.
Mutation and selection. The concept of sexual selection was introduced by Charles Darwin as an element of his theory of natural selection. [1] Sexual selection is a biological way one sex chooses a mate for the best reproductive success.
In other words, predispositioning is a method responsible for creation of a predisposition. Randomness is a formation of inconsistent linkages between the stages of the system's development. In this context, for instance, Darwinism emphasizes the exclusive role of chance occurrences in the system's development since it gives top priority to ...
Neoteny is the term for reaching sexual maturity without undergoing metamorphosis. [ 36 ] The genes responsible for neoteny in laboratory animals may have been identified; however, they are not linked in wild populations, suggesting artificial selection is the cause of complete neoteny in laboratory and pet axolotls.
