"Why is so much of Nature at war with other parts of Nature? Because there isn't one Evolution directing the whole process. There's as many different "evolutions" as reproducing populations. Rabbit genes are becoming more or less frequent in rabbit populations. Fox genes are becoming more or less frequent in fox populations. Fox genes which construct foxes that catch rabbits, insert more copies of themselves in the next generation. Rabbit genes which construct rabbits that evade foxes are naturally more common in the next generation of rabbits. Hence the phrase "natural selection"."
