Like their prehistoric ancestors, these peoples live in small groups of 25-30: in the modern period, groups can be found in africa and south america. They survive as forager, hunter and fishers. Life expectancy is ~35 years: ~30% reaching 40+ years of age. Cave dwelling people may have not completely lived in the cave. Diseases of these groups include: intestinal parasites. Drinking water has eggs of parasites in it. Animals: salmonella, botulism, lice, wound/bone infections, pneumonia, zoonotic diseases. Pre-sapien humans did not have this problem.
