Deer have affects. Their brains arent that different. What they probably do not have, are the understanding for, andthe capacity to dothe advanced interpretations of the incoming perceptions thatwe can.This does not mean that they comprehend the familything, like we do, and they sure arent likley to share our beliefs of what is right and wrong.
Its no coincidence that so much of medical research is made on rats and ferrets. Even so when psychofarmaceutical drugs are conerned.Should this mean that we should not hunt them. Well not in my opinion anyway.
