What theory is the Kennewick Man linked to?
Forensic anthropologist Douglas Owsley, who later led the scientific team that examined Kennewick Man’s skeleton in 2005, discovered that the bones in Kennewick Man’s arms were bent. Owsley theorized that this was the result of powerful muscles built up over the course of a lifetime of hunting and spearfishing.
What race was Kennewick?

Who won the Kennewick Man case?
With Wednesdays ruling, the three-judge Appeals Court panel upheld the decision to allow scientists to study Kennewick Man. The researchers contend that analysis of the remains will help answer questions about how humans came to populate North America.
Why was the Kennewick man so important?

Native American tribes said that the bones were the remains of an ancestor and moved to reclaim them in order to provide a ritual burial.
How do scientists extract DNA from bones?
We drill into the bone and collect the bone powder. We soak the bone powder overnight in an extraction buffer, a substance that melts the bone and collagen and releases the DNA into the solution. Now that the DNA is in solution, we need to get it out. To do that, we do what’s called a silica extraction.
Is the Kennewick Man Polynesian?

Can DNA be extracted from teeth?
Extraction of DNA from teeth samples yields sufficient amounts of good quality DNA useful for PCR-based diagnostic methods. The teeth could serve as a reliable source of DNA for amplification-based forensic methods in sex determination. DNA could be obtained from any tooth, regardless of the age of subject.
Can DNA be extracted from fingernails?
In forensic analysis, fingernail material can serve as an important source of DNA. 1, 2 Because of the special composition and structure of fingernails that embody DNA in keratinized cells, DNA extraction procedures are more complex than usual protocols applied for fresh somatic cells.
What is the history of the land bridge theory?
The theory of a land bridge has fueled the imagination of explorers and scientists for centuries. In 1590, the Spanish missionary Fray Jose de Acosta produced the first written record to suggest a land bridge connecting Asia to North America.
