I guess going with straight history and biographies just aren't enough for the average viewer.
What was wrong with “Hitlers Jurrasic Zoo on the “American Heroes Channel”?
It was actual history about something the nazis actually did try to do and one more example of the nazi progressivism. The project was overseen by overseen by Herman Goring. Lutz and Heinz Heck were the brothers who did the actual work.
They were trying to recreate “the forest primeval” in Poland by attempting to breed animals like the Aurochs Bull back into existence for stocking in the forests that had been cleansed of people. They also bred super agressive dog/wolf crossbreeds for the forest. They also bought bison from the USA for breeding with the local species. Goring had dreams of recreating an extinct species of wild horse as well as a subspecies of mammoth that once lived in the area.
