Things in the present are different from the way things were in the past, so they had to change. During historical times species of animals have become extinct and new breeds of domesticated animals have been created. Even those creationists who believe that the world was created 6000 years ago by a God who created fake fossils just to make fools of paleogeologists admit that things have changed since.
The creationists just don't like the idea that things changed by natural processes. They want natural things to have changed according to God's specific orders, not by themselves through a process that can be understood by science.
Evolution was a scandal from the beginning, when the popular churches were more credible. The traditional Christians thought it heretical to say we were related to the apes because that wasn't spelled out in the bible. The landed aristocracy thought it was worse than heretical; they thought it was in bad taste.
But the new-rich middle class found that the idea of evolution could justify their upward social mobility, so they preached a "Social Darwinism" that said that rich Anglo-American businessmen were the endpoint toward which evolution had been driving. But as soon as the entrepreneurs themselves became the establishment they dropped evolution as too conducive to leveling, which they equated with labor unions, socialism and anarchism.
Evolution became an intellectual scandal again in the 1920s in the "monkey trial" when the teaching of evolution was criminalized in the Bible Belt as dangerous to the status quo. It might, after all, imply that we were all human despite the color of our complexion.
But World War II made us more sophisticated. In the post-World-War-II era evolution was generally accepted by the educational bureaucracy as part of the worldview that gave bureaucrats upward social mobility.
Since the 1960s there's been a growing populist revival of Christian and Islamic fundamentalism. The fundamentalist Moslems have had "the West" and Zionism as an external enemy to stir up emotions and maintain control over their followers. In a similar way the fundamentalist Christians are using evolution as the stalking horse to attack the educational bureaucracy at the point they are weakest.
This kind of persistent attack from religious and social conservatives has made the academic bureaucracy defensive. The Darwinians have taken the tack that there is a consensus of academics who agree that evolution is "scientific fact".
Of course evolution is an abstraction, and not any kind of "fact". But leaving that aside, when you consider all the other foolish notions that have gained the consensus of academics and all the new paradigms that academics have rejected, it is clear that the evolutionists have really only stated that evolution is a dogma of the contemporary biological academic bureaucracy. That makes their position morally and philosophically equivalent to that of the creationist fundamentalists and leaves a vacuum in which a new paradigm has room to be born.
