Blacks are actually adapted for super high population turnover. High birthrate, fast maturation time. Blacks typicaly have sex much younger, are more sexually aggressive in general, they have a shorter maturation time (mustaches by like age 12), a shorter gestation time (on average born several weeks earlier), the offspring are typically lighter weight, with smaller size. They have very loose and chaotic family structure completely different from the pair-bonded families you see with more northern populations. They are prone to dying in large numbers and have little regard for human life since it's easily replaced by their super high birthrate.
This population is basically evolved to be super high-turnover, high-birthrate population. That's because they evolved in a tropical environment with abundant food resources where this style of reproduction is rewarded. This is called r-selection, when a population promotes "quantity over quality". More focused on generating lots of offspring rather than high quality offspring.
The story is different in more northern latitudes where food is scarce. They prioritize having only a few offspring, but ensuring those few have super high parental investment.
As a result, the babies have a longer gestation time, they take longer to mature, life is more precious (super high prohibitions against things like murder and theft), super tight knit pairbonded family structure. The babies also typically have much larger heads, in fact baby heads got so large that large numbers of women died in childbirth, and thus needed to develop wider hips. African hips are very narrow by comparison.
K selected populations are associated with high civiliation, high intelligence. Hence why the more northern Japanese, Korean, and Chinese civilizations outclass the darker skin civilizations of Southeast Asia and the Aboriginal Austrlians who are heavily r-selected.
Blacks actually have a much higher incidence of twins than whites or asians. About 8x higher than whites and 16x higher than asians.
