Evolution through natural selection is taught in Biology class because that is what Biologists think is the theory that explains the facts. It is in fact the only Scientific theory of Biological change that has not been falsified. If and when a better theory or a refinement of the theory comes along it will be embraced if and only if it is a better explanation for the facts (such as punctuated equilibrium and the neutral mutation theory).
There are no men in Black Robes setting down dogma for the Temple. There are thousands of individuals worldwide who know the data, do research in the field, and try to come up with something novel or revolutionary. This is how the community of Science works. If what you say is “hot” and people who listen to you find “new hotness” then you will be listened to. If what you say is bovine excrement and the people who listen to you find a dead end, you will be ignored as a cook or a crank. Guess where all the Flood Geologists ended up? How about the Lamarkian Evolutionists? The Geocentrists? (Ooops, are you still agnostic about Heliocentrism? Sorry.) The Flat earthers? The Alchemists?

You are correct. They wear White Robes...and they are quite open about setting down dogman for the temple. Either tow the party line or face the consequences:
