ABSTRACT
This paper begins with a refutation of the orthodox model of final Pleistocene human evolution, presenting an alternative, better supported account of this crucial phase. According to this version, the transition from robust to gracile humans during that period is attributable to selective breeding rather than natural selection, rendered possible by the exponential rise of culturally guided volitional choices. The rapid human neotenization coincides with the development of numerous somatic and neural detriments and pathologies. Uniformitarian reasoning based on ontogenic homology suggests that the cognitive abilities of hominins are consistently underrated in the unstable orthodoxies of Pleistocene archaeology. A scientifically guided review establishes developmental trajectories defining recent changes in the human genome and its expressions, which then form the basis of attempts to extrapolate from them into the future. It is suggested that continuing and perhaps accelerating unfavorable genetic changes to the human species, rather than existential threats such as massive disasters, pandemics, or astrophysical events, may become the ultimate peril of humanity.
