^ This is the correct answer. If you look at the amount of DNA we share with other primates, like, say, the Bonobo, it is clear humans could be re-classified to more accurately reflect our close genetic ties to them.

But, here is the thing: It is we humans who define the categories into which we group genus/species, etc. And we really love to think of ourselves as extra special. So, the idea of including ourselves with a group of non-human animals goes against the grain of society, no matter how genetically accurate it would be.

This is the correct answer. In my years working in wildlife rehabilitation, I handled multiple rabies positive animals, primarily infected bats and fox and one skunk. Each of them displayed symptoms typical of distemper, which, in many wild animals, can cause neurological disorders.

They are often confused, are incapable of fleeing and are therefore, more likely to bite because they are more likely to come in contact with humans.
