i thought i’d start running through pinker’s “war deaths chart” to see if i can work out any/some of these populations’ mating patterns. already posted about the semai (low violence rates, outbreeders) and the yąnomamö (greater violence rates than the semai, inbreeders).
as you can see, the kato are at the top of pinker’s list. (in the 1840s, the kato were fighting the yuki, so remind me to post about them, too.)
from The North American Indian. Volume 14 [pg. 11]:
“Marriage was arranged between the two persons concerned without consulting anybody else. Having secured a girl’s consent her lover went clandestinely that night to sleep with her, and at dawn he stole away. The secret was preserved as long as possible, perhaps for several days, and the news of the match transpired without formal announcement, even the girl’s parents learning of their daughter’s marriage in this indirect fashion. His marriage no longer a secret, the young man might then erect a house of his own. The bond was no more easily tied than loosed, for either could leave the other for any reason whatever, the man retaining the male children and the woman the female. Children were not regarded as belonging any more to the paternal than to the maternal side. When adultery was discovered, the only result was a little bickering and perhaps an invitation to the offender to take up permanent relations with the new love.”
sounds like cousin marriage was not insisted upon in kato society. otoh, sounds like there were no proscriptions against it, either. so matings in kato society could’ve been close — at least some of the time.
from Native Americans: An Encyclopedia of History, Culture, and Peoples [pgs. 156-57]:
“Marriage was generally a matter between the couple involved, although girls were generally prepubescent when married. The Cahto practiced polygyny as well as the taboo that prevented a man from addressing his mother-in-law directly. Divorce was easily obtained for nearly any reason.”
again, no apparent insistence upon, or prohibitions against, cousin/other close marriage. however, from here [pg. 247] we learn that the pre-contact kato population was ca. 1,100 individuals. that’s not very many! with such a small population, it would be very difficult, indeed, to avoid inbreeding. (don’t forget, too, because native americans went through a bottleneck coming to the americas, they’re all relatively related to one another — genetically speaking. so any inbreeding would be even more inbred than in other populations — if that’s the right way to put it [i know it's not!].)
interestingly, from Handbook of North American Indians, Volume 8: California [pg. 244]:
“The Cahto lacked a true tribal organization. During precontact time there are estimated to have been 50 villages, with the permanent settlement situated in the three valleys where the town of Cahto once stood, and the towns of Branscomb and Laytonville now stand.”
another question is whether or not the kato married non-kato people. they were, apparently, on quite friendly terms with the pomo indians and many of them spoke pomo. did they marry out? dunno.
so, the kato? i’m gonna call it: probable inbreeding.
kato lady (she looks nice!):
