[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; they are not linked in wild populations, suggesting artificial selection is the cause of complete neoteny in laboratory and pet axolotls. [ 37 ]
Known for his work in the fields of descriptive anatomy and histology, he eventually became associated with studies involving evolutionary theory, developmental history and anthropology. In 1884 Kollmann introduced the term "neoteny" to define the transformation process where animals such as newts mature sexually while still in the larval form. [3]
Louis Bolk. Lodewijk 'Louis' Bolk (10 December 1866, Overschie – 17 June 1930, Amsterdam) was a Dutch anatomist who created the fetalization theory about the human body. [1] ...
