Neoteny and reduction in skull size – grey wolf and chihuahua skulls. When the role of dogs expanded from just being working dogs to also being companions, humans started selective breeding dogs for morphological neoteny, and this selective breeding for "neoteny or paedomorphism" "strengthened the human-canine bond."
Intelligence played a role in the acquisition of food, through the use of tool technology such as stone anvils and hammers. [ 10 ] There is no direct evidence of the role of nutrition in the evolution of intelligence dating back to Homo erectus , contrary to dominant narratives in paleontology that link meat-eating to the appearance of modern ...
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.
It has been suggested that sexual selection played a part in the evolution of the anatomically modern human brain, i.e. the structures responsible for social intelligence underwent positive selection as a sexual ornamentation to be used in courtship rather than for survival itself, [4] and that it has developed in ways outlined by Ronald Fisher ...
This probably relies on the evolution of non-coding genomic regions. The consequence of the neoteny could be an extension of the period of synaptic plasticity and therefore of learning. A human-specific duplicated gene, SRGAP2C accounts for this synaptic neoteny and acts by regulating molecular pathways linked to neurodevelopmental disorders. [25]
Advocates of EDP assert that evolutionary psychologists, while acknowledging the role of the environment in shaping behavior and making claims as to its effects, rarely develop explicit models (i.e., predictions of how the environment might shape behavior) to support their claims . [5]
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.
