A nice example of the so-called Baldwin Effect, or "phenotypic plasticity" - in which the same genome can result in differing phenotypes, depending on the local environment. Any future genetic mutations that have an effect on cecal valves or bite strength or so on, will thus be selected for (or against) much more strongly than they would otherwise be.
