A lot of midwit takes itt for an actually interesting question.
The book 'The Boys From Brazil' explore an interesting concept. Namely the idea that Mengele and other Nazis fled to Brazil and in the shadow of the Reich continued their human experiments with a specific look to manipulating the human genome. This idea spread in part because of actual Nazis that fled to smaller parts of Brazi and the unique case of the township of Linha Sao Pedro which has an extremely high occurrence of twins. It was later confirmed that Sao Pedros twins were not a result of genetic manipulation but the idea of Nazis using Brazil as a testing ground for what they learned playing God in the dark recesses of the death camps is genuinely interesting.

TL;DR: The Nazis would have used South America as a testing ground for their Übermench experiments entirely unchecked and created a race of beautiful Aryans with Big Brazil Butts®.
