印度的本尼以色列社区居民有犹太人血统

A new study from Tel Aviv University, Cornell University and the Albert Einstein College of Medicine reveals genetic¹ proof of the Jewish roots of the Bene Israel community in the western part of India. They have always considered themselves Jewish. "Almost nothing is known about the Bene Israel community before the 18th century, when Cochin Jews and later Christian² missionaries³ first came into contact with it," says first author Yedael Waldman of both TAU's Department of Molecular⁴ Microbiology and Cornell's Department of Biological Statistics and Computational Biology. "Beyond vague oral history and speculations⁵, there has been no independent support for Bene Israel claims of Jewish ancestry⁶, claims that have remained shrouded⁷ in legend."

 

"Human genetics now has the potential to not only improve human health but also help us understand human history," says Prof. Eran Halperin of TAU's Department of Molecular Microbiology and Biotechnology and TAU's Blavatnik School of Computer Sciences, who together with Prof. Alon Keinan of Cornell University's Department of Biological Statistics and Computational Biology advised Waldman. The research was published in PLOS ONE on March 24, 2016. 

 

From folklore⁸ to science

 

According to their oral history, the Bene Israel people descended⁹ from 14 Jewish survivors¹⁰ of a shipwreck¹¹ on India's Konkan shore. The exact timing¹² of this event and the origin and identity of the Jewish visitors are unknown. Some date the event to around 2,000 years ago. Others estimate that it took place in 175 BCE. Still others believe their Jewish ancestors arrived as early as the 8th century BCE.

 

"In the last few decades, genetic information has become an important source for the study of human history," says Prof. Keinan, the study's senior author. "It has been applied¹³ several times to the study of Jewish populations across diasporas, providing evidence of a shared ancestry."

 

The research team, including members of Prof. Keinan's lab, Prof. Eitan Friedman of TAU's Sackler School of Medicine, and Prof. Gil Azmon and colleagues at Albert Einstein College of Medicine and the University of Haifa, based their study on data from the Jewish HapMap project, an international effort led by Prof. Harry¹⁴ Ostrer of Albert Einstein College of Medicine, to determine the genetic history of worldwide Jewish diasporas. They used sophisticated genetic tools to conduct comprehensive genome-wide analyses on the genetic markers of 18 Bene Israel individuals.

 

"We found that while Bene Israel individuals genetically¹⁵ resemble local Indian populations, they constitute a clearly separated and unique population in India," Waldman says.
