drink.

But this anthropologist says it may have offered a substantial source of calories and carbohydrates.

In fact, Professor Raven Garvey claims that a 1,000 pound bison would have provided enough

digesta for 25 adult foragers to meet the USDA's average recommendations for proteins

and carbs for three days.

I don't know what that says about the USDA's dietary recommendations, but I had no idea

the behavior of ice age humans.

If these folks could harvest their vegetables and protein from a single bison, a prehistoric

Walmart one-stop shop, it's possible that hunter-gatherer activities were less strictly
