New research is suggesting yet another twist on how evolution creates itself. The research tells us more about epigenetics, so first we need to review how epigenetics has already falsified much of evolutionary theory. I’ve written this before but it bears repeating. The adaptation of species to environmental pressures would seem like obvious evidence for evolution. But in recent years we have begun to understand the enormous complexity of adaptation. It is not a story of natural selection acting on undirected biological variations (that is, variations that are blind to environmental pressures). This sort of undirected process has been the evolutionary dogma for the past century. In what was known as the Modern Synthesis, biological adaptation was described as resulting from blind variations resulting, for instance, from genetic rearrangements or unguided mutations. No thanks to evolution we are now beginning to understand the real version of biological adaptation. What we are seeing is an incredibly complex adaptation machine that tweaks the designs of organisms in response to environmental pressures. Read more
