  • Life Expectancy



    Upper Paleolithic 33 yrs

    Neolithic 20 yrs


    Someone pointed this out to me the other day apropos of human history and asked why there is such a disparity between the average life expectancy of Neolithic man and Paleolithic man.

    The paper referenced from Kaplan et al doesn't explain the difference. Anyone have any insight into this?

    My guess is around 10,000 B.C. some big enviromental changes started to occur, warming of the planet and likely a lot of things were changing. As temperatures warm up disease and bacteria are more prevelant, which could of lowered the age. This is my educated guess.

          The really *bad* communicable diseases (think smallpox, cholera, dysentary) are species jumps from domesticated animals. Easily spread from person to person within a village or city whose population isn't the best nourished. Now that's really going to lower life expectancy.
