How much do we have in common?

The Chilean scientist, Mauricio Moraga, makes an interesting badysis of our present and our past. The comparison of ancient mitochondrial DNA, our ancestors, and modern, helps to better understand our origins.

The title of the study is "From the initial establishment of the continent to regional geographical differentiation: a diachronic study of maternal lineages in human populations of Chile", and as he has mentioned in El Mostrador, the central idea is to link the genetic traces of the lineages present in the Chilean Metis population with those found in ancient American samples.

The geneticist is part of the human genetics program of the Institute of Biomedical Sciences and their studies could provide relevant data to understand migratory movements inside and outside the country. Chile, for example, we could know more precisely when a territory was populated and how much we have of these aborigines, in addition to understanding the lineages of the original populations.

Mauricio Moraga mentioned to the same means that with this pro He continues his research on mitochondrial DNA and uses it as a marker to badyze the colonization of Chile and America. South:

"We want to find lines that have never been detected in the indigenous populations, which are few and which, the first mbadive exterminations of the Conquest, obviously its genetic variability is greatly diminished. as the crossover took place from indigenous women and Spanish men, the Chilean mitochondrial DNA was mainly indigenous.

Our idea is to examine this mitochondrial DNA in mixed race samples of the general population and to compare It results results with those we get from old samples, in order to see if they appear markers that are not in the native populations present them, but that are in the old, and so we can connect them.
