Sad but real. Necessity breeds unity, however as creatures of natural selection, we are evolved to all make ourselves more fit and more successful for selection. We compete, have wars and are in conflict because it is woven into our basic biology. Unity exists in biology only as an anomaly, because the complexity of your biological existence from your brain to your arms, hand and feet exist because your ancestors triumphed over others.
