Abstract
Indigenous peoples have occupied the island of Puerto Rico since at least 3000 BC. Due to the demographic shifts that occurred after European contact, the origin(s) of these ancient populations, and their genetic relationship to present-day islanders, are unclear. We use ancient DNA to characterize the population history and genetic legacies of precontact Indigenous communities from Puerto Rico. Bone, tooth, and dental calculus samples were collected from 124 individuals from three precontact archaeological sites: Tibes, Punta Candelero, and Paso del Indio. Despite poor DNA preservation, we used target enrichment and high-throughput sequencing to obtain complete mitochondrial genomes (mtDNA) from 45 individuals and autosomal genotypes from two individuals. We found a high proportion of Native American mtDNA haplogroups A2 and C1 in the precontact Puerto Rico sample (40% and 44%, respectively). This distribution, as well as the haplotypes represented, supports a primarily Amazonian South American origin for these populations and mirrors the Native American mtDNA diversity patterns found in present-day islanders. Three mtDNA haplotypes from precontact Puerto Rico persist among Puerto Ricans and other Caribbean islanders, indicating that present-day populations are reservoirs of precontact mtDNA diversity. Lastly, we find similarity in autosomal ancestry patterns between precontact individuals from Puerto Rico and the Bahamas, suggesting a shared component of Indigenous Caribbean ancestry with close affinity to South American populations. Our findings contribute to a more complete reconstruction of precontact Caribbean population history and explore the role of Indigenous peoples in shaping the biocultural diversity of present-day Puerto Ricans and other Caribbean islanders.

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.
