How do the size and shape of human canines compare with chimp canines

Human canines are blunt and small in size, while chimps have big and sharp canines.

Explanation:

Chimps' mouths are larger than humans' mouths. Chimps have a flat palate; and bigger and sharper canines than humans. Also, there is a space between these teeth and the teeth at the front of the mouth. On the other hand, humans' mouths are smaller, which leads to smaller and less sharp canines, and there is no space between these teeth and the teeth at the front of the mouth.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
