Nestled in a remote area of Brazil lies the town of Cândido Godói's filled with blonde,
blue-eyed twins. The town of approximately 7,000 people has a 1,000 percent
higher rate of twins than the global average. Researchers say that the blonde,
blue-eyed features of these twins are not surprising as the town is largely
populated by German immigrant descendants; however, the frequency of twin
births is still a mystery.
Mengele in South
America
Many believe that former SS officer Josef Mengele roamed
South America posing as a physician and veterinarian. Argentine historian Jorge
Camarasa explains in his book, Mengele: The Angel of Death in South America,
that Mengele probably continued twin experiments from World War II while on the
run. Camarasa also says that interviews with local people say they remember a
traveling German doctor with mysterious potions. They recalled him by different
names, but all recognized his picture.
Twin Boom Occurrence
Before Mengele
Researchers looked to the town's baptismal records to get
some background on the exceptional twin birth-rate. These records date back to
1927 and cover about 75% of the children born. Even during that time, there was
an exceptional rate of twinning. The records also indicate that there was no
"surge" in the rate of twins in the 1960s.
There also continues to be a high rate of twin births, which
rules out Mengele completely. If Mengele had injected mothers to alter the
pregnancies, the twin rate should have stopped when his "work" ended.
Other Theories
The neighborhood of Linha São Pedro is home to 44 pairs of
twins. In the early 20th century, there were a mere 8 families;
today there are 80 households. Local residents suspect that there is something
in the town's water, food, or air that is causing the twin birth rate to be so
high.
Some cite the founder effect, where one or two members of
the founding families were predisposed to having twins. When small, isolated
groups settle in a region, the original settlers' predispositions are passed
down as families intermarry repeatedly. This is seen in a lot of isolated
towns, but they have not gotten publicity.
