Human Footprints Found in Mexico: 40,000 Years Old
Not sure how I missed this one, but CNN is reporting that fossilized human footprints have been found volcanic ash in Mexico. The volcanic ash has an age of 40,000 years! If this is true, this blows away the previous theory that humans arrived in North American as recently as ~13,000 years ago! Gonzalez said the footprints were preserved as trace fossils in volcanic ash along what was the shoreline of an ancient volcanic lake. “Climate variations and the eruption of the Cerro Toluquilla volcano caused lake levels to rise and fall, exposing the Xalnene volcanic ash layer,” Gonzalez said.
