Skydiving? The statistical increase in spousal abuse during pregnancy... starving a child to death for not saying "amen" after mealtime prayers?

Once again; nature tests the adaptations, whether the adaptation is to over come an environmental issue, a disease, a mutation or competitor, if the animal does not succeed the consequences can be swift but not necessarily. In the end who is the better survivor is filtered. If spousal abuse can not be addressed by society and it causes a survival crises then that society will die. If the consequences are indifferent, which means the animal lives long enough to reproduce and care for offspring to maturity, then the behavior does not interfere with survival. E.g. Male chimpanzees are very abusive to female chips but the behavior does not interfere with survival of the species...
In the end, despite humanities intellectual prowess, the process of chaotic systems converging on social order is no different than any other animal and no different than any other chaotic system that converges to an ordered system. So long as the behavior of the elements (individuals) in a system exchange information where they affect one another the system will order itself. Such chaotic phenomena is rooted in mathematics and is not a product of intellectual awareness or invention. This is a consistency thought out nature, from sub-atomic particles, atoms, molecules, DNA, neurons, animals, solar systems, galaxies and the universe.
