If humans were adopted to a purely or even largely vegetarian diet, humans would have small chests an an enormous distended belly with miles of digestive track in which plant matter can linger and ferment, sort of like cows, or like gorillas with their cone shaped rib cage sitting atop a big sack of a belly.

They do. Not miles, but our digestive tracts do match those of natural herbivores. More information here.

They don't. More information
