For most of the 20th century, the solution to the mystery of the original Americans-- where did they come from, when, and how?--seemed as clear as the geography of the Bering Strait, the climate of the last ice age, and the ubiquity of finely wrought stone hunting weapons known as Clovis points. According to the ruling theory, bands of big-game hunters trekked out of Siberia sometime before 11,500 years ago. They crossed into Alaska when the floor of the Bering Strait, drained dry by the accumulation of water in a frozen world's massive glaciers, was a land bridge between continents, and found themselves in a trackless continent, the New World when it was truly new. The hunters, so the story went, moved south through a corridor between glaciers and soon flourished on the Great Plains and in the Southwest of what is now the United States, their presence widely marked by distinctive stone projectile points first discovered near the town of Clovis, New Mexico. In less than 1,000 years, these Clovis people and their distinctive stone points made it all the way to the tip of South America. They were presumably the founding population of today's American Indians. Now a growing body of intriguing evidence is telling a much different story. From Alaska to Brazil and southern Chile, artifacts and skeletons are forcing archaeologists to abandon Clovis orthodoxy and come to terms with a more complex picture of earliest American settlement. People may have arrived thousands to tens of thousands of years sooner, in many waves of migration and by a number of routes. Their ancestry may not have been only Asian. Some of the migrations may have originated in Australia or Europe. 1. What is the main idea of this passage?
