Beijing ? A Mongolian professor of history has said America was discovered by the Mongolians and not Christopher Columbus, as is popularly believed, the Xinhua news agency reported late on Thursday.

Professor Sumiya Jambaldorj from the Genghis Khan University in the Mongolian capital, Ulan Bator, performed a study proving the similarity between American place names and words in the Mongolian language.

“About 8,000 to 25,000 years ago, Mongols with stone tools crossed the Aleutian Islands and arrived in America,” Jambaldorj was reported as saying.

The academic said that over 20 place names in the Alaskan Aleutian Islands could be Mongolian.
