The Effects of European Colonization: Analysis of Genetic Admixture in the Canary Islands and Mauritius

Date and Time: 
Thursday, May 22, 2014. 05:00 PM - 06:30 PM
Meeting Location: 
Archaeology Center, building 500, seminar room
Meeting Description: 

Rosa Fregel aims to understand ancient and historical migration processes by the analysis of human remains and its comparison with modern populations. An important part of Fregel's research has consisted of the temporal evolution of human inhabitants of the Canaries by comparing prehispanic, historical and modern populations. Fregel is interested in the effects that the conquest and posterior European colonization had on the Canarian aboriginal people and on determining if there are differences in maternal and paternal parental populations’ contributions to the modern population. 

One of Fregel's current projects deals with the study of human migrations related with the transoceanic slave trade and the indentured laborers in Mauritius. This project is in collaboration with the Mauritian Archaeology and Cultural Heritage project and Stanford University. Fregel is analyzing historical human remains from two archaeological sites: Le Morne (slavery period) and Bois Marchand (indentured laborer period), and modern human samples in order to determine the temporal evolution of the genetic composition of Mauritius.

In this workshop Fregel will review how Genetics could unravel migratory processes and help to study the effect of European colonization and slave trade in two different admixed populations: the Canary Islands and Mauritius.

Speaker bio: Rosa Fregel's research expertise is focused on human population genetics, principally using mitochondrial DNA and Y-chromosome markers on ancient and modern DNA samples. Fregel obtained her bachelor's degree in Biology from University of La Laguna in 2003. She completed her PhD in 2010, funded by the Canarian Government and awarded with the PhD European award and the Excellent PhD prize of University of La Laguna. During 2010-2014 she has worked as a postdoctoral researcher in Las Palmas de Gran Canaria and La Laguna universities, and now at Bustamante Lab in Stanford University.
