The most controversial archaeological finding was the Kennewick Man. The skeletal remains of the ancient man were found in In the summer of 1996 when 2 students happened to stumble on the remains that ended up being the most controversial in history. The skeleton was 8,500-years old and was a Native Americans on Native American soil. That sparked a big debate between Native Americans and scientists. The Native Americans wanted to rebury the remains but as you can imagine, that was not going to happen.
Where does science and history trump the values and traditions of cultures of people? This is a good example and the perfect answer to that question. Whenever the modern day archaeologist feel the object is more important than the values of the people, they will overrule and such is the case for the Kennewick Man. In the past, Native American graves have actually been looted and many other horror stories abound about the disregard for the Native American cultural beliefs about their dead as well as that of other cultures too.
