Cavemen Didn't Die at 30. So How Did Ancient Kids Reach 15?

Cavemen didn't die at 30 — but for a Stone Age kid, just reaching 15 was a coin toss. Meet Tak, a hunter-gatherer boy, and follow him from two days old to fifteen: weaning, fevers, campfires, rivers, snakes, a hungry big cat… and the crew that kept him alive. Why do humans wean their babies years earlier than chimpanzees? Why did grandmothers and older siblings matter so much? Did fathers make as big a difference as we think? Are human kids really safer than chimp kids? And what was the one enemy no grandmother could stop — and what finally beat it? To find out, we lean on research with living hunter-gatherers like the Hadza of Tanzania — the closest comparison we have, not a time machine. ▶ Part 1 — Did Cavemen Really Die at 30?:    • Why Ancient Humans Didn't Actually Die at 30   CHAPTERS 0:00 Meet Tak: the kid who made it to 15 1:02 When the milk runs out: weaning 2:53 The camp kid: fire, rivers and snakes 4:20 The forager: kids who feed themselves 5:46 The crew: grandmothers, siblings and dads 7:03 Are human kids safer than chimp kids? 7:31 The invisible enemy: what really killed kids 8:12 Not alone SOURCES Gurven, M. & Kaplan, H.
