I watch quite a lot of science programmes and read quite a lot of ideas on animal and human behaviour.
Some people seem to believe that all human instincts can be shown in the behaviour of animals. for example choosing a mate, or doing whats best for the individual and the grup etc.
but i don't believe this too be true, i think that as humans we are completely isolated from the animals. our highly developed brain yes retains our ancestors instincts but i think our ability to analyse and make moral decisions sets us apart completely from animals and nothing of what we do can be shown in the animal kingdom.
i'm probably going to get flamed for this post but its just my opinion on the matter.
