Chimpanzees often engage in bullying, murder, stealing, deception for personal gain (especially in sex)...etc...Bonobos much less. (Bonobos use sex to defuse potential conflicts "Make love, not war!" )
It is not clear whether this involves DNA/hard-wiring, evolution, or a primate type of situational ethics. Perhaps a little of each. We certainly see aspects of ourselves when we observe them. Since 98% or so of our genes are the same, who is surprised?
