5000 years ago pastoralists in Kenya created a burial site with a specific plan.\nFor at least the next 400 years, possibly as long as 800 years, over 500 people\nof all ages and classes were buried with amazing precision and care. With no\nsystem of writing it's unclear how they accomplished this. Dr. Elizabeth\nSawchuk, one of the researchers on the project, gives us some insight into life\naround Lake Turkana 5000 years ago and about the people buried there.
