Sexist sex-segregation again on the run at Harvard

The desperate search for evolutionary traces supporting sexist sex segregation prejudices (see From Klevius without love) is perhaps best exemplified by the notorious Lawrence Summers, the president of Harvard University, and his fanatic ideas abt innate sexism. Now a "researcher" at the same university, Coren Apicella, delivers the next stupidity on this path by wildly speculating ("We really don't know what is behind this yet") that males with deeper voice pitch are better breeders (made me think abt high pitch Somali males in Sweden with some ten kids each - yes, of course I know it's the same cultural sexism but in the shape of Islam). Apicella conducted her "research" by driving randomly in Tanzania and asking pygmy-like statured Hadza males abt their kids! But when there is a positive expectation/demand for a certain result, the quality of the research usually suffers. It's also noteworthy that human evolution during the last two million years has been precisely in the opposite direction, namely towards less, not more, sexual dimorphism, i.e. we (in general, - I don't know abt Summers) have distanced ourselves from Gorillas, Orangutangs etc! It may also be noted that according to Frank W Marlowe "Hadza men value fertility in a mate more than women do, and women value intelligence more than men do"! Furthermore, according to Klevius, one may also consider the effects of Bantu/Arab gene flow (not the least because of Bantu/Islamic slavery) on a pygmy-like population (or didn't she even control for the stature/pitch relation?!).
