Scientists: Americans older than thought
Footprint discovery suggests humans were on continent 40,000 years ago

LONDON, England (AP) -- British scientists claimed on Tuesday to have unearthed 40,000-year-old human footprints in central Mexico, challenging previous studies that put the arrival of the first humans in the Americas at about 13,500 years ago.

Scientists Silvia Gonzalez, from Liverpool John Moores University, and Matthew Bennett, of Bournemouth University, found the footprints in an abandoned quarry close to the Cerro Toluquilla volcano in the Valsequillo Basin, near Puebla, south of Mexico City in 2003.

Gonzalez said the footprints were preserved as trace fossils in volcanic ash along what was the shoreline of an ancient volcanic lake.

Wow. I would have never guessed that the first americans were that old.
