What was the life expectancy for a pre-civilization person?

by Westnest

By that, I mean pre-Neolithic revolution. We always hear that it's 20-25, but it t doesn't sound credible since somebody has to raise the offspring. It's most probably with counting the infant mortality, but what about people who survived into adolescence? How old would they expect to live into?

Hi, you might consider x-posting to our sister sub /r/AskAnthropology since the pre-Neolithic quite firmly prehistory. There are some anthropologists here, but more there who specialise in earlier time periods.
