This weeks question has to do with the discussion concerning
carnivores, herbivoves, and omnivores. What we wonder is if there has
ever been any observation of mollusks changing their behavior, in
responce to changing environment. That is, do they change when
polution changes their environment, or storms upset their biome? Is
there evidence that separated populations of the same species behave
differently due to differences in their environment?
    It seems that such an ability would aid ones evolutionary
possibilities. Just wondering.
