Population genetics of Latin America and Oceania

Genetic data is transforming the understanding of our own species and refining historical chapters at different scales around the globe. However, despite the globalization of biotechnologies to analyze the human genome, indigenous populations from the Americas and Oceania remain underrepresented in large-scale genomic studies. In this talk, I will discuss recent efforts to characterize the genetic profile of Indigenous Americans throughout the analysis of ancient and modern DNA, as well as their relationship within and beyond the continent, including the possibility of prehistoric contacts with Pacific Islanders. This topic poses challenges and opportunities to adequately study human diversity not only for the benefit of genetic research and science, but also for the benefit of the local communities, which are bearers of a unique evolutionary history that has been recorded in their DNA. This rapidly evolving field also raises questions about the best practices when studying the DNA of underrepresented ancestries while conducting cutting-edge science in a more equitable way.
