Scientists who have studied the genetic past of an Icelandic family now claim the first Americans reached Europe a full five centuries before Columbus bumped into an island in the Bahamas during his first voyage of discovery in 1492.

Researchers said today that a woman from the Americas probably arrived in Iceland 1,000 years ago, leaving behind genes that are reflected in about 80 Icelanders today...

"As the island was practically isolated from the 10th century onwards, the most probable hypothesis is that these genes correspond to an Amerindian woman who was taken from America by the Vikings some time around the year 1000," Carles Lalueza-Fox, of the Pompeu Fabra university in Spain, said.
