This week we discuss two separate regions in South America. We discuss the hunter gatherer groups living in Argentina and how they had been genetically isolated from the rest of the continent. We also discuss the various groups of peoples who had migrated from the Orinoco River valley to occupy the Guianas to become prolific hunter gatherer fishers and would begin to travel up and down other rivers into the Amazon Basin and how they would being to colonize the Caribbean.

This week's episode we discuss the site of Monte Verde in southern Chile and some recent controversy surrounding the site's dating. We also talk about the brutal Atacama Desert and how this environment led the fishers moving through the region to develop several forms of mummification throughout their long history in the region. For this season that covers natural mummification as well as the black mummy method.

This includes the river valleys of the Sechin/Casma, the Rio Grande of the Ica Region, and the water basin of Lake Titicaca. We also cover some of the cave art being painted in Andean rock shelters in what is now Bolivia.
