I'll take the opportunity to insert some thoughts from metaphysics here. It says that the evolution of humanity begins with total unity, and just as total lack of reason: if one was to lose a finger, others would feel the pain, but wouldn't understand why. In order to develop reason, humanity descends into individualism. The extreme social division today is the sign of passing the midpoint of evolution when mind is fully developed, but the sense of unity is lost. After that the course of evolution will take us back, but we'll get to keep the skill of reasoning. Returning to the origin will be forced by shared hardships: the divisiveness will die off under their pressure.
