South American genetic and cultural diversity, connections between linguistic and genetic patterns at a global scale
Global diversity of Genes and Languages
The relationship between cultural and biological diversity was examined to better understand population origins, diversification, and interactions. Instances where linguistic and genetic variations do not align are often dismissed as exceptions to the norm. But how frequently do these discrepancies occur? To answer this, we compiled a new genetic database and integrate it with relevant qualitative and quantitative linguistic and cultural data.
The Inca expansions and the diffusion of Quechua
The history of the Inca offers a compelling case study for understanding the development and expansion of complex societies, as well as the connections between archaeological and linguistic evidence. The Incas led the final major phase of the Quechua language family’s spread, but did they achieve this through population movement, cultural assimilation, or a complex combination of both? Additionally, to what extent has the current distribution of languages been shaped by more recent European contact?
Rethinking the genetic history of the Southern Cone
After their initial migration from Beringia, the first settlers of the Americas journeyed southward until they reached the Southern Cone. Although this timeline is widely accepted, archaeological evidence points to surprisingly early dates for the earliest human remains in this area. Recent ancient DNA studies reveal a complex population structure that challenges our current understanding of early migration patterns. Could the Southern Cone represent more than just the final chapter in the peopling of the Americas? How does this history connect to the indigenous heritage of the region?
Human spread and collapse in the Americas
The Americas, shaped by recent waves of population movement and post-colonial transformations, offer a unique opportunity to explore the genetic imprints of these significant demographic shifts. The continent’s complex history of migration and diversification has given rise to some of the world’s richest cultural and linguistic diversity. Can we uncover these historical pathways within the genetic makeup of the diverse populations that inhabit various regions, environments, and speak myriad languages today?
