if we imagine all life on earth on a phylogenetic tree, it is proven that there is a difference in intellect between species driven by genetics
if we zoom-in to a very fine level, where we can see individual humans, it is self-evidently obvious that there is a difference in intellect between individual humans which has substantial heritability
but if we partially zoom out to the Walsh and Yun level of genetic population clusters corresponding to the traditional anthropological categories, we are beaten with the ostensible factoid that ALL difference disappears
by what mechanism do you propose that it disappears, save that of ideology?
by strict logic, population clusters must differ in frequencies for alleles associated with polygenic traits like intellect
but there's no special biological mechanism that erases differences precisely at the population-cluster / racial level
ergo, the mechanism is ideological: selective emphasis, framing, and suppression, in order to maintain a socially-acceptable narrative
the reality—despite your unwillingness to accept it—is that there are racial differences in intellect, exactly as there are at the special and individual levels

somebody being dead doesn't make them retroactively less human
claiming that culture alone drives human evolution is reductive—I think they're widely considered to be symbiotic
genes aren't passive, and they play a significant role in enabling civilisation-forming cognitive, social, and physical abilities
if a population cluster wholly lacks genes we associate with higher intellect, and they consequently have lower neuronal density, lower cranial capacity, a cerebral geometry which under-emphasises the PFC, and they don't have an advanced civilisation, is that BECAUSE they don't have a civilisation, or because they lack the abilities to create one on a mental (and thus genetic) level?
