Nearly 500 years after the death of Christopher Columbus, a team of genetic researchers are using DNA to solve two nagging mysteries: Where was the explorer really born? And where the devil are his bones?

Debate about origins and final resting place of Columbus has raged for over a century, with historians questioning the traditional theory that he hails from Genoa, Italy. Some say he was a Spanish Jew, a Greek, a Basque or Portuguese.

Even the location of his remains is the subject of controversy. The Dominican Republic and Spain both stake claims as the final resting place of Columbus, who died in May, 1506.

The Spanish-led research team, which includes Italians, Americans and Germans, sampled DNA from the known remains from Columbus' brother and son, and then compared them to fragments attributed to Columbus in Seville.

Although the official announcement is expected later this year, Italian researchers say they are confident based on the evidence gathered so far that Columbus' supposed remains in Seville are likely authentic.
