First Americans...1.3 million years ago?

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.

If the new dates are correct, the footprints could be among the most incredible hominid traces ever discovered—or, more likely, not footprints at all.

"One-point-three million years is a lot older than I expected," said Paul Renne, director of the Berkeley Geochronology Center at University of California, Berkeley.

Lotsa controversy there. Read more here.
