Archeology of the Americas

Until recently, the most widely accepted interpretation of the archaeological evidence suggests a series of migrations from Siberia over a land bridge near the end of the last ice age. However, recent finds in Brazil have changed the way archeologists think about how the Americas were settled. Among these finds is a 12,000 year-old skull which is closely related to the aboriginal peoples of Australia and Melanesia. Cave paintings show images of giant armadillos, which died out before the last ice age. They also show the oldest painting of a boat anywhere in the world. Archaeologists speculate that the first Americans drifted unknowingly from Australia.

There are various alternatives to that theory, and unconventional, unrelated diffusionist theories abound. These alternative theories generally are based upon less evidence and lack a large following.

In the United States, physical anthropology (archeological investigations based on the study of human remains) is complicated by the Native American Graves Protection and Repatriation Act, (NAGPRA), which provides for the bodies of Native Americans and grave goods to be turned over to their tribe. In some cases, notably, that of Kennewick Man, this has affected human remains many thousands of years old which seem to have no connection to the modern tribes which are requesting relief under the act.
