I finally stumbled across a constant that may explain a high female to male birth rate among certain remote peoples of the world.
In and around Iquitos, Peru at the headwaters of the Amazon, it’s said that the birth ratio is 3:1, but my observation of thousands of people on the paths & streets is that it’s closer to 2:1, nonetheless statistically significant. Explanations offer everything from soil to diet to genetics, but I think it has to do w/ a high genocide among the recent past population from e.g. combat, malaria, cannibalism & so forth. Now here in Lake Toba, Sumatra among the Batak people there is also a remarkably high ratio. I was told it’s 3:1, but in observing perhaps 1000 Batak of Lake Tabo it’s closer to 4:1.
Yesterday I motor biked the 100km ring track at 10mph around the remote Toba island that’s the center of the Toba tribe, and by rough count among the 500 school children who each yelled gleefully, ‘hello meester’, the ratio was 5:1. the locals offer no explanation, but complain of the male dearth. I’ve been beleaguered to get married, and to their friends. The locals believe the birth factor lies in the female rather than male, though I was taught that genetically males choose the sex.
The cafe owner where I just ate has a string of 5 female children, and it is common to run to 7 before a male is produced. Everyday a husband runs off with another woman in hopes of producing a son to carry on his family name; if she doesn’t birth a male after a few, then he tries another. I won’t get married, but am not shy about exploring other aspects of the situation. No solid explanation emerges from the talks, but there are definite constants among both the Peruvian, Amazonians and the Batak for the disportionate birth ratio. It so happens that each race is at the top of the world (in the 100+ countries traveled) for hardiness– I stated this before discovering the birth ratio. By hardiness, I mean strong physical superiority, with a slight mental one also (being related to physiology). The Batak kids look like Arnold Schwarzenegger at age 8, and then grow up. Both sexes among the Peruvians & Batak, but particularly the females, are perfectly proportioned, comely, and among the hardest workers in the world. Their stamina and resistance to discomfort at work or play is outstanding, and I trained for decades to reach that level that the kids of both places own. Diet, soil and water are not commonalities, nor exactly is environment, for the Peruvians live in a low jungle & the Toba Batak in a high jungle surrounding a volcanic lake. Both races are highly sexual, however the Amazonians are relatively promiscuous while the Batak don’t practice much before marriage. The only constants, besides strong physical appearance & beauty, appears that each race emerged from cultures that in recent history had a high death rate for various reasons. For the Peruvians it’s malaria & jungle beasts, while for the Bataks it’s fleeing from the mainland to a remote harsh burg. Both recently practiced cannibalism.
Somehow it all seems to have made the female more fertile for female births, like calico cat where only a few males may service a female preponderance to propagate the race. It makes sense evolutionarily, but not genetically unless one looks at calicos where a male birth is rarer.
