Native American History Being Told by Archeology

An article in the magazine Liberalis published by Utah State University College of Humanities and Social Sciences says some interesting things.  It looks at the work of Dean Patricia Lambert.  She studies bones.  She started studying the Native populations of Santa Barbara Channel Islands (Island of the Blue Dolphin) and discovered that this society was not always peaceful; there were times of violence and conflict.  She discovered that 22 percent of male deaths from AD 600 to 1350 were attributable to violence.  Less than half that for female deaths.  She also found that periods of drought, there was a higher rate of violence.
She has since turned her studies to ancient civilizations of the four corners area.  She found a similar pattern.  She also noted that there were periods of genocide, where one group or culture would try to eliminate another, so as to reduce competition for resources.  He also provided evidence that cannibalism was also a trait of some of these cultures. This she discovered by studying the bones, but also excrement from these ancient people.
Putting together the story of PreColumbian peoples is hard.  There is hardly no written evidence.  However the bones are giving details as to their lives.
I recommend this article if you have the chance.
