Bullshit. Africans tend towards r-selection. This isn't neccessarily going to guarantee predators. Gracility in the more agriculturally-tending Yaruba offshoot tribes can be seen in many of the effete physiological attributes of continental Blacks. Sure, it may translate into low frustration tolerance and aggressiveness, but without the other qualities of predation and dominance like the appropriate physiology to engage in persistence hunting (better a speciality of the physically dissimilar Khoisan than any Negroid), and an ability to translate those into any targeted focus, it's basically tantamount to impotent tard-rage.
In European miscegenation with Blacks over the last century and a half, heterogenization effect might've enhanced previously unpredatorial characteristics, but prior to the point of European ancestry say of a mullato, the Black is generally speaking a weakling, prone to flight upon confrontation, with craniofacial metrices like outturned ears to ensure they aren't being spotted as prey by oncoming predator, etc.
