Via Genetics and Health I came across this story:
But modern-day science often unearths secrets long buried. When the DNA results landed on Isaac Owusu's dinner table here last year, they showed that only one of the four boys - the oldest - was his biological child.... I'm not interested in the details of the story (immigrants who find out their putative children aren't their biological issue). Rather, whenever I bring up paternity I do note angry comments seem to emerge unbidden from regular readers who ordinarily seem placid. Why? The reality in the United States is that it is in the "child's best interest" to have a father, and whoever gets "tagged" with fatherhood has a lifetime's worth of bills. But I'm interested in some more "deep time" questions, because the issue of paternity is important to two threads we've discussed on this weblog of late: facultative homosexuality and selection in pre and post Neolithic societies. ![]() What does this mean for the evolution of human societies? We've alluded to the power of reproductive skew and within group variance being heightened after the transition to mass societies because of the spread of agriculture. We've also alluded to the possibility of metapopulation dynamics and within group dampening of status & reproductive variance in hunter-gatherer conditions. Though it is a rare individual who takes no interest in the fidelity of his putative mate, the study of small scale societies seems to suggest that the extreme tendencies of Arab cultures are not manifest within them. Rather, infidelity generates discord, irritation or anger, but there are no great material or status inheritances at stake. But once super-males arose with mass societies and the emergence of "men in groups" then the stakes were raised. Harems guarded by eunuchs are the logical end stage of the development of the super-male optimal strategy, but there are many small steps along the way. Pre-Neolithic societies were never "matriarchal" and "peaceful," and I suspect that Marijas Gimbutus' Old Europe was no such culture. But, Old, Old Europe might have been a bit less fixated on sexual paternity because the stakes across the generations were just not as large.
