The biological origin of the Tainos is one of the most controversial issues regarding the population history of the Caribbean. The archaeological evidence suggests an early arrival from Mesoamerica and later arrivals of Arawak speaking groups from the Amazon to the Greater Antilles. We sequenced the control region of 171 Hondurans mtDNAs, 140 of which were of Native American origin, including 119 belonging to haplogroup A2, 20 to B2 and one to C1. We then chose Puerto Rico and Dominican Republic...
Assessing the genetic diversity in the extant Chachapoya population from northeastern Peru using uniparental DNA markers (mtDNA and Y-chromosome) (2015)
The aim of the study is to elucidate the origin and population history of the human communities from northeastern Peru, with both contemporary and ancient DNA data. For the first phase of the study, contemporary Y-chromosomal (23 STRs) and mitochondrial (HVR1 and HVR2 sequences) data from four populations (Chachapoya=276; Jivaro=47; Huancas=21 and Cajamarca=34) distributed in the northeastern region of Amazonas (Peru), was assessed. At haplogroup level, the markers showed differential...
Preliminary ancient DNA analysis suggests a complex origins scenario for pre-contact Puerto Rican populations (2016)
Recent archaeological research suggests that indigenous groups in Puerto Rico stemmed from multiple and continuous migrations of continental indigenous populations. This view is supported by contemporary genetic studies, which have found evidence of genetic affinity between multiple modern Native American groups and the native ancestry components of modern, admixed Puerto Ricans. Overall, these findings challenge the traditional single-migration model for the peopling of Puerto Rico, and suggest...
