Competition among groups isn't a distinctly human characteristic. What is distinctly human on this planet is our capacity to become aware of our own mortality, and perhaps in turn react in a ruthless panicking behavior of delusion-reinforced conflict. However, we also have the capacity rise above the 'teeth and claw' and accept our impermanent existences and attempt to usher in a better world for our species through cooperation. Unfortunately, people are too attached to their delusions for the latter to come to fruition any time soon.
