A paleolithic woman would have had her 3rd kid at around 20 years old tops. Seeing that kid to adulthood is still less than 40 years old. Age-related eye problems don't usually show up until you're over 40.
- jessaustin 9y agoOh I thought the proposed expectancy was 30; 40 is more plausible. Also, a third viable child produced by 20 indicates a fairly rosy local situation. Every viable child would have nursed for at least two years. Infant mortality was much higher. Menarche took place later than in modern humans. Famine was more common. One might think that would simply mean that fertility was lower than I'm proposing, but if you look at what paleolithic humans did that is simply impossible. On foot, they occupied every part of every continent save Antarctica. That required fertility significantly above replacement.
