I’ve been reading lately about grave sites that were discovered near Lake Baikal. Most of the men buried there seem to have been around 35 years old at their death. (Women and children were also found there, in smaller numbers.) No cause of death was given in the reports I was reading.
So, you’re a hunter-gatherer. You’re living in a colder climate (the climate near Baikal then was roughly similar to today’s climate, by all accounts). But the food sources (mostly fish, plus some deer, seal, other small land mammals) are abundant. You have sophisticated stone and bone tools, fishhooks made of both materials, and even jewelry and other ornaments made from animal teeth, bone, or jade.
How did you likely die, at age 35?
I always assumed that such deaths for men would be caused by
(a) intertribal warfare (as is common in many of the remaining Amazon tribes)
(b) infection (specifically, infected wounds, etc., since many other deadly contagious diseases were byproducts of animal husbandry)
I have always thought (again, judging by some of the Khoi-San and other African “Bushmen” tribes, among whom anthropologists have met individuals who are in their 80s and 90s, and accounts of well-known ancients who lived into their 70s) that even though we always talk about “life expectancy” of human beings in the prehistoric (or, often, simply the premodern era) being about 35 years, that the number was derived based on (a) high infant mortality and (b) high rates of death from disease and war, and not from people somehow “aging” faster than they do now. In other words, I would expect a neolithic hunter-gatherer, who survived childhood and managed not to get killed in warfare or by an infected cut or from starving to death in a bad year, would live to be around 70.
Am I wrong, and the men of Baikal were elderly at 35? Or is it likely that they died young from infection/trauma?
