Can we find a sort of "moral" behavior in the animal field? Darwin recognized for first that animals which are as well as human being "social creatures" inevitably acquire something like a moral sense or a conscience. We don't know if animals feel pain for others but some more recent experiments have shown some similarities with human hallmarks. A quite violent example dated 1964 had as protagonist a chimp. It had learned to pull a chain. When It pulled the chain it received food but at the same time, another monkey(the same race) had an electric shock. The majority of these chimps within this experiment stopped of eating for 12 days, until the end of the experiment. It would probably be been the same behavior of each of us. This empathy rises when the others are members of our family or social group. In another experiment always a monkey, in this case, cappuccino race, gained food for a work. It should have split the food with a mate. If the other was a member of the same group the division was equal; if not, the monkey didn't care about the right amount. Scientists haven't still now proofs on moral concerns in the animal kingdom but we can't ignore some basic-inner social instincts that they possess.
