This chapter presents some of the main issues relating to language diversification in South America. How to explain the large number of genealogical units (107–118) in the continent, in view of its relatively recent human settlement, probably around 15,000 years ago? First the chapter presents the major language families such as Arawakan and Tupian. Then the chapter describes the major typological patterns characterizing the continent and their geographical distribution in terms of linguistic areas and the putative Andean-Amazonian divide, which is questioned here. A number of potential explanations for the diversity are presented: few large empires, geographical barriers, late development of food crops, possible effects of European invasion, ethos of ethnic boundary maintenance, and low population densities until recently. There is no conclusive evidence yet for any single explanation. The chapter concludes with a brief summary of the chapters in the book regarding South America.

Abstract Purpose of Review In this review, we report on the state of knowledge about human Q fever in Brazil and on the Guiana Shield, an Amazonian region located in northeastern South America. There is a contrast between French Guiana, where the incidence of this disease is the highest in the world, and other countries where this disease is practically non-existent. Recent Findings Recent findings are essentially in French Guiana where a unique strain MST17 has been identified; it is probably more virulent than those usually found with a particularly marked pulmonary tropism, a mysterious animal reservoir, a geographical distribution that raises questions. Summary Q fever is a bacterial zoonosis due to Coxiella burnetii that has been reported worldwide. On the Guiana Shield, a region mostly covered by Amazonian forest, which encompasses the Venezuelan State of Bolivar, Guyana, Suriname, French Guiana, and the Brazilian State of Amapá, the situation is very heterogeneous. While French Guiana is the region reporting the highest incidence of this disease in the world, with a single infecting clone (MST 117) and a unique epidemiological cycle, it has hardly ever been reported in other countries in the region. This absence of cases raises many questions and is probably due to massive under-diagnosis. Studies should estimate comprehensively the true burden of this disease in the region.
