Race realism. Autistic = racialy white behavior
First of all, race is absolutely real, with anthropologists able to tell someone's race just by looking at their skull.
1. Carnivores tend to have orbital hypotelorism.
The eyes are closer together. Obligate carnivores have their eyes closer together, whereas herbivores like deer have eyes on the sides of their head. Reason: in order to have better depth perception be able to catch prey.
2. Carnivores tend to have smaller mesiodistal tooth dimensions. Reason: carnivores need small, sharp teeth to tear flesh, whereas herbivores have larger teeth to grind fibrinous vegetation.
3. Carnivores have microchelia.
Reason: Lips are tactile organs, one function of which is to grasp long stalks of vegetation. Herbivores have bigger lips.
4. Carnivores tend towards brachycephalism. Obligate carnivores (such as cats) have a shorter skull shape than herbivores such as horses, with omnivores such as dogs and bears in between (a long head interferes with predation).
5. Obligate Carnivores have "autistic behavior." This is like the behavioral difference between cats and dogs, or wolves and dogs. Autism as we know, is a pseudoscientific disorder amongst a wider spectrum of what is considered normal. Or at least normal for a predatory species.
