You know the guy, Otsi, the 5000 year-old mummy found in the Italian Alps back in 1991? Well now we know that the fellow ate wild goat, plus some wheat grains--in fact the ancestor to today's wheat grains--before being shot in the back with a stone arrow. He ate a hearty meal, at least 1/2 pound of food, apparently. And what he ate perfectly described his era--a combo of hunted food and gathered food, possibly even cultivated food.
Isn't archaeology/anthropology grand?
