Abstract
Summary of the research findings
This review synthesizes archaeological, linguistic and genetic evidence about the Tupi linguistic family, arguing that Tupi likely originated in the southwestern Amazon and subsequently expanded (with distinct Tupinambá and Guarani branches). The authors summarize demographic, cultural and biological patterns, discuss José Brochado's Tupi Expansion model (linking agricultural development and territorial expansion), and highlight outstanding questions about Tupi history and diversity.
