Fossil footprints stir debate about earliest Americans

Science

In July a team of English researchers reported the discovery of human footprints in Mexico that appeared to be 30,000 years older than when most scientists believe humans arrived in the Americas.

Researchers commonly accept that humans came to the Americas some 11,500 years ago. But new dating of the Mexican find suggests that the features are in fact 1.3 million years old.
