Maybe you've been hit in the head by too many rocks? Viruses can attack an organism because their proteins fit into a "slot" on the surface of the cell. If humans had nothing physically to do with animals, why should they have such similar "slots" to those found in animals (specifically mammals in this case)?Are you a rock?
Explain why you get a headache if I hit you on the head with a rock if you aren't a rock?
