Zombie Science! On the Evolution of Zombie Populations

From coalesced:

T-Rex thinks he's eliminated zombies with logic. The basic idea: Zombies depend on human brains to survive, but they also must bite humans (turning them into zombies) to create more zombies. If zombies were really good at catching humans and eating their brains, there would be no more humans and the zombie population would die off. Conversely, if the zombies had trouble getting to the human brains, they could convert humans into zombies (by biting them without eating their brains), but they would starve due to brain deprivation.
