Scientists looking for Columbus' origins with DNA

Spanish scientists are trying to learn more about Christopher Columbus' early years by studying the DNA samples taken from those bearing the explorer's name.

Since multiple theories of Columbus' origins have been proposed, the experts hope that cheek swabs will shed new light on his heritage. Among theories put forth are the son of a weaver from Genoa, the illegitimate son of a Portuguese prince, the son of converted Jews, or a rebel in the medieval kingdom of Catalonia. DNA samples are being collected from those with the names Colon and Columbo.
