World History#1¶

Info

信息1：So fifteen thousand years ago, humans were foragers and hunters. Foraging meant gathering fruits, nuts, also wild grains and grasses; hunting allowed for a more protein-rich diet so long as you could find something with meat to kill.
信息2：By far the best hunting gig, in the pre-historic world incidentally was fishing, which is one of the reasons that if you look at history of people populating the planet, we tended to run for the shore and then stay there. Marine life was: A. abundant, and B. relatively unlikely to eat you.
