Nova:  Mystery of the First Americans

 

1. Forensic scientists (anthropologists), archeologist, but also specialists in medicine, dentistry, and genetics.

 

2. In the case of Kennewick Man, evidence for severe injuries suggested that the man lived many of his 40-plus years in frequent if not chronic pain.

 

3. 40 years old (middle aged)

 

4. The Corps has kept Kennewick Man locked up under tight security in a museum at the University of Washington, pending the outcome of court battles over what should be done with the bones.

 

5. The U.S. Army Corps of Engineers

 

6. Several Indian tribes on the Columbia Plateau, led by the Umatilla, hope to win the right to rebury the skeleton, which they consider an ancestor.

 

7. When it seemed likely that the Indians would achieve their goal under the Native American Graves Protection and Repatriation Act -- a law that enables tribes to file claims to remains to which they can demonstrate a cultural affiliation

 

8. A group of eight leading American anthropologists, fearful that invaluable information on the first peopling of the Americas could potentially be lost, sued the federal government for the right to study the remains.

 

9. ANSWERS WILL VARY

 

10. It's a way to determine the age of organic remains such as bone, teeth, and seeds by finding out how much carbon-14 is left in the remains.

 

11. 9,000-year-old

 

12. So every plant contains a certain percentage of carbon-14. And so do those things that eat plants. And so do those things that eat the things that eat plants.

 

13. The carbon-14 within every once-living thing will someday turn back into nitrogen-If we knew the amount of carbon-14 a once-living thing had while it was alive and the rate at which it changed (i.e., how fast it changed) back into nitrogen, then we could figure out how long ago it lived.

 

14. Carbon-14 has a half-life of 5,730 years.

 

15. 5,730 years ago.

 

Tri-City Herald Virtual Center: Kennewick Man eats

18. 25-30 people which included children

 

19. far north as Spokane, east and west to the Cascades and Blue mountains and south to the Hermiston area

 

20. 475 to 500
