Replying to @JayMan471
Again,
(a) all substantial reproductive differences in HSS are endocrine (developmental).
(b) All variations in endocrine expression are environmental (geographic) and reproductive (demand).
(c) Primary selection is depth and rapidity of maturity(masculine) vs neoteny (feminine).
(d) groups can rapidly select for endocrine expression made possible by geographic (env.) selection, rapidly altering distribution.
(e) In times of opportunity or crisis groups have demonstrated rapid selection through concentration of male dominance or scarcity.
(f) resulting differences in current racial and sub-racial groups are determined by time of fork, oppy for population expansion, selection for maturity or neoteny, and distribution of dimorphism between male and female endocrine traits.
For these reasons my opinion is that you have been and remain, counter-signaling the wrong argument (often) out of cognitive frame bias.
Group Selection by shifts in demand for reproductive rates of different traits demonstrably exists. Hence 5’3″ brunette rates of birth.
