Coordinates: 27°57′S 54°46′W / 27.95°S 54.767°W Country Brazil Region South State Rio Grande do Sul Founded September 10, 1963 Government - Mayor Valdi Luis Goldschmidt (PMDB) Area - Total 246.275 km2 (95.1 sq mi) Elevation[1] 322 m (1,056 ft) Population (2007) - Total 6,934 - Estimate (2008) 6,762 - Density 26.5/km2 (68.6/sq mi) Time zone UTC-3 (UTC-3) - Summer (DST) UTC-2 (UTC-2) Postal code [2] Cândido Godói is a municipality of 6,641 inhabitants in the state Rio Grande do Sul, Brazil near the Argentinian border, famous for the high number of twins born there. The twin phenomenon is centered in Linha São Pedro, a small settlement in the city of Cândido Godói, in an ethnically homogeneous population of German descent.[3]

Twinning rate
The rate of twin births in Cândido Godói is 10%, significantly higher than the overall 1.8% rate for the state of Rio Grande do Sul.[3] This rate is unusual, exceeding the highest observed national twinning rate (4.5-5% for southwestern Nigeria[4]). Half (8 of 17) of twins examined in one study were monozygotic (identical) twins, a few more than the average of 30%.[3] Twin births were noted from the early twentieth century, when the first colonists included seventeen sets of twins, and have been observed through several generations in the latter part of the twentieth century.[5]
The population is largely of Polish or German ancestry, with many tracing ancestry to the Hunsrück region of Germany, which has a higher than average twinning rate.[5]. The rate in Cândido Godói could reflect genetic founder effect: rare genetic traits occurring by chance among a small group founding a community will be more common among their descendents than in the population at large.
Theories
The notorious Nazi doctor Josef Mengele, who had conducted twin studies in Germany, is known to have fled to South America as the Allies were closing in on the Nazi German regime. The Argentinian historian Jorge Camarasa has proposed the theory that Mengele conducted experiments on women in the area, which could be responsible for the high ratio of twins.[6][7] About the time of Mengele's arrival in southern Brazil in 1963, the incidence of twins began to increase, leading to the current rate of twinning at 1 in 10, over half of whom are dizygotic (fraternal).[3][8] However, such speculation has been disputed by local historian, Paulo Sauthier, who says Mengele did not study twins during his time in Brazil. Moreover, according to geneticists, the most likely explanation for the high frequency of twins is genetic isolation and inbreeding.[3][8][9] Records indicate that the high frequency of twins predates Mengele's arrival to South America.[10]
This phenomenon of a large number of twin births is not unique to Cândido Godói, and has also been observed in the town of Igbo-Ora in Nigeria and the village of Kodinji in India.
