In the termite Kalotermes flavicollis, neoteny is seen in molting females. [42] In other species, such as the northwestern salamander (Ambystoma gracile), environmental conditions – high altitude, in this case – cause neoteny. [43] Neoteny is also found in a few species of the crustacean family Ischnomesidae, which live in deep ocean water ...
Neoteny is the retention of juvenile traits well into adulthood. In humans, this trend is greatly amplified, especially when compared to non-human primates.
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.
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.
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.
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 ...
Neoteny is the term for reaching sexual maturity without undergoing metamorphosis. [ 35 ] 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. [ 36 ]
