This is correct. The Expensive Tissue Hypothesis of brain/gut development pretty clearly shows that a switch to eating meat and hunting coincided with a shortening of our intestines and enlarging of our brain, making us human.

Incorrect. ETH postulates that there could be a correlation between gut length and brain development, the paper explicitly states that there could be an alternative methodology for how we manage the metabolic requirements for our brains. Back to the point on humans having canines. Herbivores also have canines to tear through fibrous plant material see (gorilla, baboon and hippo).
