I understand they used the concept of root races and genetics didn't exist yet, which is why individual ancestry was important. But obviously someone had done the racial research which allowed, for example, honorary aryan, or more precisely, asiatic-aryan status, for the Japanese. Is there anything available which provides their racial analysis of the various peoples? Or was it as simple as, if a swastikas appears in their past, they are worthy of consideration? Status? Whatever? How did they account for population migrations and complete demographic replacements over time?
