Superiority of the human feces


" Human feces reveal much about ancient human
dietary practices. The oldest know are from
Homo erectus at Terra Amata (France) that may
date to 300,000 ya.
"Fossilized feces" are called coprolites.
How can you tell if they are human? Human
coprolites soaked in trisodium phosphate
solution for 72 hours turn brown to black. No
other species produces this effect. "

(Note in a reader, from "The Evolution of Human
Nutrition" by Barry Bogin.)
