We didn't see much evolution of Homo Sapiens in the last 1000s of years.
We had a lot of shaping by selection of existing traits but not that much long term evolution. We're essentially "running on the same hardware" as these pre-house Homo Sapiens.
What allowed prehistorical Homo Sapiens to live for 50 years now lets us do so for 80.
- b112 3y agoLeaving aside modern evolutionary theory, your assertion about the same hardware agrees with my position. You need to look at life expectancy rates for the last 200 years. The big change is in the 1900s. Not when we first built warm, heated houses, thousands of years ago.
- thriftwy 3y agoI agree with you, though I believe that live expectancy was very uneven back then. You want either modern medicine and sanitation, or low population density. The latter is very hard to combine with low wear and tear. So it's really both medicine and comfort.
