Lutz and Heinz Heck were zoologists and curators of the zoos in Berlin and Munich in the 1920’s, who successfully took varieties of cattle from across Europe and back-bred the ones which looked most like the bulky shouldered and long-horned (forward) auroch cattle much seen in European paleo cave art, to “revive” that “species” which reportedly was achieved, so the Heck brothers probably knew all humans are of one syngameon, as all of those cattle types are of another, thus Hitler’s “aryan race” but a branch of the progeny of the eight on Noah’s Ark, which provably would not have been music to Hitler’s ears.
