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]
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.
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.

Desmond Collins, who was an Extension Lecturer of Archaeology at London University, [8] said that the lengthened youth period of humans is part of neoteny. [9] Physical anthropologist Barry Bogin said that the pattern of children's growth may intentionally increase the duration of their cuteness. Bogin said that the human brain reaches adult ...
In 1928, the English embryologist Walter Garstang showed that tunicate larvae shared structures such as the notochord with adult vertebrates, and suggested that the vertebrates arose by paedomorphosis (neoteny) from such a larva. The proposal implied (if it were correct) a shared phylogeny of tunicates and vertebrates, and that heterochrony was ...
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.
