There is no fundamental truth to evolution. There is no how, there is no observation, there is not even a stable theory like in most sciences. All there is is a lot of verbiage. Evolution is not science, it is an ideology. An atheistic/materialistic ideology which like all other ideologies has to back up its tenets with force instead of facts. That is why it must tyrannize everyone that disagrees with it - because the evo emperor has no clothes and if people start saying it the whole hoax will be over and the prostitutes of evolution will be out of work.
Indeed. So much, in fact, that even the biggist critics of the creationist and ID movements concede that evolution has become a secular religion.
