Twins

NY Times:

...

Like so many in this farming town, populated almost entirely by German-speaking immigrants, Mr. Grimm, 19, believes that something in the water — a mysterious mineral, perhaps — is responsible for the town’s unusual concentration of twins.

“It can’t all be explained by genetics,” said Mr. Grimm, himself a twin.

Geneticists would like to disagree with him, but even they have no solid explanation for the 38 pairs of twins among about 80 families living in a one-and-a-half-square-mile area.

The mystery has persisted for decades, attracting international attention and inspiring books and investigations by geneticists. It is one reason locals are in no hurry to try to prove their water theory. They are too busy posing for journalists and marketing their town to tourists as the “twins capital of the world.”

Some researchers have suggested the darker possibility that Josef Mengele, the Nazi physician known as the Angel of Death, was involved. Mengele, residents say, roamed this region of southern Brazil, posing as a veterinarian, in the 1960s, about the time the twins explosion began. In a book published last year, an Argentine journalist, Jorge Camarasa, suggested that Mengele conducted experiments with women here that resulted in the higher rate of twins, many of them with blond hair and light-colored eyes. The experiments, locals said, may have involved new types of drugs and preparations, or even the artificial insemination Mengele claimed to know about, regarding cows and humans.

My maternal grandmother was a twin. She was also was of German extraction. She had 11 children none of which were twins, but one of her daughters had twins. We have always suspected that it was genetic and passed only to daughters. That is an area of study they should apply to the German immigrants in this community. I think it is a more reasonable explanation than the water or Doctor Death.
