Abstract

Studies of Native American genetic diversity and population history have been transformed over the last decade by important developments in anthropological genetics. During this time, researchers have adopted new DNA technologies and computational approaches for analyzing genomic data, and they have become increasingly sensitive to the views of research participants and communities. As new methods are applied to long-standing questions, and as more research is conducted in collaboration with indigenous communities, we are gaining new insights into the history and diversity of indigenous populations. This review discusses the recent methodological advances and genetic studies that have improved our understanding of Native American genomics and population histories. We synthesize current knowledge about Native American genomic variation and build a model of population history in the Americas. We also discuss the broader implications of this research for anthropology and related disciplines, and we highlight challenges and other considerations for future research.
