The obesity epidemic/ Example 1: a physical manifestation of psychological neoteny. Paedogenesis – the retention of juvenile traits in mature adults – is one result of neoteny. This process has gone so far that individuals are turning their bodies into “big babies” as an external display of infantile narcissism. Helplessness is the dominant theme, just as it is with infants. This “faux baby” body is achieved through lifestyle choices, not evolution.
Extreme neoteny epidemic/ Example 2: skull does not develop into that of an adult but retains infant – child proportions. This is the result of domestication-through sexual selection. Modern social humans are the product of domestication for “tame” behavior, and like puppies, genetically-linked traits are preserved.
