Mexico City ? A scientific reconstruction of one of the oldest sets of human remains found in the Americas appears to support theories that the first people who came to the hemisphere migrated from a broader area than once thought, researchers say.

Mexico’s National Institute of Anthropology and History on Thursday released photos of the reconstructed image of a woman who probably lived on Mexico’s Caribbean coast 10,000 to 12,000 years ago.

Anthropologists had long believed humans migrated to the Americas in a relatively short period from a limited area in northeast Asia across a temporary land corridor that opened across the Bering Strait during an ice age.

But government archaeologist Alejandro Terrazas says the picture has now become more complicated, because the reconstruction more resembles people from southeastern Asian areas like Indonesia.

“History isn’t that simple,” Terrazas said. “This indicates that the Americas were populated by several migratory movements, not just one or two waves from northern Asia across the Bering Strait.”
