Mystery Race Here Before Indians
New radiocarbon testing on 27 skulls that were found in Mexico 100 years ago shows some of them are almost 13,000 years old, the oldest found so far in the Americas. Domestic tools 14,500 years old have been discovered in Chile, but no human remains were found with them. The two oldest skulls are long and narrow, while more recent skulls are short and broad, like those of American Indians.

Before this, archeologists thought Indians were the first people to arrive on the continent, by way of a temporary land bridge from Asia.
