El pasado mes de septiembre nuestro artículo colaborativo "Paleogenómica y Bioarqueología en México" fue publicado en la revista Cuicuilco de la Escuela Nacional de Antroplogía e Historia de México. El mismo cuenta también con la participación de los investigadores Miriam J. Bravo López, Miguel A. Contreras Sieck y Kelly E. Blevins. Es el primer artículo reseña sobre ADN antiguo en español que conocemos hasta el momento. En el mismo reseñamos la larga trayectoria de investigación con ADN antiguo en México, y sus aplicaciones a la bioarqueología, con especial énfasis en los estudios de historia poblacional humana y paleopatología. También discutimos la necesidad de llevar a cabo estudios de ADN antiguo de forma ética y sustentable en América Latina; y concluimos con una reflexión sobre el prometedor futuro del campo de la paleogenómica en México. El artículo esta disponible de forma gratuita en el portal de la revista Cuicuilo.
My role in this work was featured in the following press coverage: 1) El Nuevo Día I was interviewed for the article Expuesto el origen de los primeros pobladores written by AAAS Mass Media Fellow Kevin Alicea Torres for El Nuevo Día, Puerto Rico's main newspaper (available for download here). This article describes how our work and the work of other colleagues are changing understanding of Puerto Rico's pre-contact history. 2) ASU Now Anne C. Stone and I were interviewed by Taylor Woods for her article New data unveils ancestry of first peoples to inhabit Caribbean published in ASU Now Letter to the Editor now published in Science: Pandemics' historical role in creating inequality7/3/2020
A preprint based on my doctoral research "Ancient DNA reconstructs the genetic legacies of pre-contact Puerto Rico communities” is now available on Bioarxiv here. In this work we use paleogenomics to reconstruct the genetic diversity of ancient Indigenous peoples from Puerto Rico and examine their origins, their relationships to other ancient Caribbean communities and their genetic links to present-day Puerto Ricans. This work was conducted with an interdisciplinary team including anthropologists, archaeologists and genomic scientists based in Puerto Rico, the United States and Australia. I describe the main points of our work in this twitter thread which you can also access through thread reader here. I am very excited to see this project come to fruition! **Update Jan 2020**: This study is now published in Molecular Biology and Evolution Our paper developing strategies for Y-chromosome enrichment in ancient samples is out now in BMC Genomics! This work was led by Maria C. Avila-Arcos (LIIGH) and includes collaborative work from colleagues at Stanford University and University of Bern. Special congratulations to first author, doctoral student extraordinaire Diana I. Cruz-Davalos (University of Bern). To see the previous version of this paper posted on Bioarxiv click here.
Our paper on successful enrichment of whole mitochondrial genomes from ancient dental calculus collected from human remains at the Norris Farms site is available on Open Access from the American Journal of Physical Anthropology.

This work was conducted in collaboration with researchers at University of Oklahoma and Penn State. |
