"Not particularly by us" OK then not particularly by anything by that logic, as we're very much included in the wide range of animals who's dietary needs have conditioned the evolution of fruit-based seed dispersal. Fact of the matter is we've been eating and pooping out seeds for the entire existence of our species and likely the entire existence of our mammalian lineage. We did evolve to eat fruit and they did evolve to be eaten by us.

We evolved to benefit from our own milk, too. Though only for the first year or so of life.
