As it turns out, the Nazi Ministry of Education published curricular guidelines in 1938, and the biology curriculum mandated extensive teaching about evolution.

I have examined numerous biology textbooks published in Nazi Germany, which were approved by the Nazi Ministry of Education, and they uniformly taught Darwinian evolution, devoting considerable attention to it in the higher grades.

If we examine the Nazi press, we find that the official Nazi newspaper, magazines, and journals occasionally published articles favorable to Darwinism. Der Biologe, the official journal for biology teachers, was taken over by the SS and regularly published articles promoting Darwinism and bashing creationism. One of these articles was by Konrad Lorenz, a later Nobel Prize winner, who argued that Darwinism was a firm basis for Nazi racial ideology. Articles against Darwinism were nowhere to be found in the Nazi press.
