Candido Godoi

While browsing on the internet I found an article about a city with a 10% rate of twins. That's unheard of. In a town of only 80 families, Candido Godoi, there are nearly 50 sets of twins. Most of which are blonde haired, and blue eyed. It is believed this is due to experiments by Dr.Mengele, he worked at Auschwitz before coming to Candido Godoi. It brings up a strong ethical question, of tampering with people genetics. Would you choose to change someone's genes?
