[3] Kidder is considered an authority on human settlements in the Mississippi River Valley and has researched how they were affected by prehistoric global climate change.
Alfred Kidder, 2d's work focused on Andean archeology, pre-Columbian art and for almost 20 years, he moderated a CBS program called What in the World?
A significant part of Kidder's recent research has focused on using geoarchaeological and geomorphic analyses to understand the dynamics of human settlement in the Mississippi River Valley.
The emergence and decline of mound building among Middle and Late Archaic cultures in eastern North America is an example of the waxing and waning of seemingly complex behavior.
[6] Kidder is currently conducting research at the Chinese site of Sanyangzhuang, a farming village buried by a Yellow River flood 2,000 years ago.
