If it's true that the social & environmental sciences are practiced with systemic bias for political reasons, it is a fortiori true of biology whenever it touches upon the theory of evolution. This is because the theory of evolution is not merely a hypothesis of interest only to biologists, but is rather the cosmological principle or founding myth of modern society. Modern society is built on an evolutionary cosmology as much as medieval society was built on a biblical one, and this is reflected in all aspects of our society (including politics, law, art, education, etc.) To do away with evolution would be to do away with modernity / modern society as such, which is why modern "scientists" cling to it so fiercely despite increasing evidence of its absurdity. To undermine the evolutionary cosmology would be to undermine the intellectual totalitarianism of the "scientific" establishment, seeing as their pride of place as educators of mankind rests on the assumption that the world is entirely material and can only be understood through material science.
