DNA helps to track Native American history

It all began with a tiny, brave band of people who strode across the land bridge connecting Asia to Alaska and into the unknown. Within a few millennia they would conquer the Americas, laying the groundwork for civilizations as varied as any in the world — the prehistoric creators of Clovis points; the Pueblo, who cut palaces straight into the sheer faces of cliffs; the mound builders of the Mississippian culture; the vast empires of the Incas and the Maya.

Their diversity was enshrined in their DNA: A new study of mummies and other remains from across the Americas found at least 84 genetic lineages from the pre-Columbian period.
