"What keeps snails and flukes apart in evolution is their divergent future interests, and this is because they do not share reproductive propagules. What keeps host genes together with host genes — and parasite genes together with parasite genes - is that they do share future interests. Parasites, then, have led us to the solution to the paradox of the organism. The genes in an organism share desiderata lists. And this is simply because they submit to the same meiotic lottery and possess the same stochastic gametic destiny."
