 In response to this sort of objection, it has been proposed that the correct explanation of a rabbit’s evolutionary success with, say, “X”, is not that this enables the rabbit to avoid dog-look-alikes, but that it enables them to avoid dogs. It is dogs, but not mere dog-look-alikes, that prey on rabbits. (This sort of response is developed in Millikan (1991) and Neander (1995).) Yet, the rejoinder is that if we really want to get at the correct explanation of a rabbit-cum-“X” system, then we should not suppose that “X” means dog. Instead, we should say that it is in virtue of the fact that “X” picks up on something like, say, predator of such and such characteristics that the “X” alarm system increases the chance of a rabbit’s survival. (This sort of rejoinder may be found in Agar (1993).)
