Summary
Innovation is the key to evolution in biological and social systems. The process appears to be formally identical in both cases. Because an excessive innovation rate can be disruptive, both systems have tools to filter it to evolutionary quasi optimal levels. In social systems these filters are of different nature. The most visible one is the last, when an innovation comes to practice, expressed as «social opposition».
Language and culture can be considered as the last evolutionary step of DNA, as an information storing-testing-processing system. For this reason, from an evolutionary standpoint, it is inevitable that this level will try to take control of the hierarchically lower strata contained in DNA. This points to genetic engineering as inevitable in spite of current opposition. Theologians and philosophers can only strive to show it is also ethic.
