Here's the puzzle: Homo sapiens have existed roughly 300,000 years, surviving at least four earlier interglacials with milder, predictable climates. None of those warm periods produced agriculture or cities. If earlier humans were equally intelligent and conditions were favorable, why didn't civilization emerge thousands of years sooner? 🤔
Multiple prior interglacials undermine climate as sole trigger for civilization
Key facts
- Homo sapiens is roughly 300,000 years old.
- Humans lived through at least four earlier interglacials with milder, more predictable climates.
- None of the prior interglacials produced agriculture, cities, or civilization.
- The argument is made that earlier humans of those warm periods were equally intelligent but never built cities.
