[15] In 1926, Louis Bolk described neoteny as the major process in ...
Neoteny is the retention of juvenile traits well into adulthood. In humans, this trend is greatly amplified, especially when compared to non-human primates.
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.
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.
The main processes involved in the embryonic development of animals are: tissue patterning (via regional specification and patterned cell differentiation); tissue growth; and tissue morphogenesis.
In the neoteny entry there are many references to a similar process, progenesis. A short description: - neoteny: the retaining of early characters (usually embryonic) in the adult. - progenesis: the earlier acquisition of sexual organs and gonads which can lead to sexually mature larval stages such as the ones mentioned in the neoteny entry.

Predisposition is the capacity humans are born with to learn things such as language and concept of self. Negative environmental influences may block the predisposition (ability) one has to do some things. Behaviors displayed by animals can be influenced by genetic predispositions.
