"Backing up this hypothesis is the fact that humans have relatively smaller large intestines than other primates. This indicates that our ancestors were eating food that was already partly broken down by fermentation."
IIRC another interpretation of the smaller large intestine is that early humans were eating more bioavailable food (i.e. meat) than other primates, which doesn't need to be broken down as much as more fibrous material (seeds, leaves, stalks etc). Can someone more knowledgable than me confirm or deny?
