Fallacy
Humans evolved canine teeth to tear flesh, and this means it is natural and normal for us to eat meat.
Response
When humans eat flesh, we don't actually tear it with our cuspids. Instead, we soften meat with cooking and then pre-tear it with utensils before grinding it down with our flattened molars, which are particularly well-suited for chewing vegetation.
Using dentition as an indicator of diet is a hard case to make. Domestic cats and dogs have similar dental structures, but cats are obligate carnivores and dogs can be vegan. Gorillas are herbivores with long canines. Our own teeth are closer to those of herbivores than carnivores, but we are capable of digesting the flesh and secretions of other species, which means that we can choose to eat plants, animals or both. So it's clear that a species' teeth are not a reliable determinant of its dietary requirements.
