An archaeological study shows us that investigating the genetics of our ancestors helps us to carry out hereditary checks that are difficult to prove in other ways. Jaime Mata-Míguez made a monitoring of the Aztec and Otomí culture by means of DNA samples. The anthropologist from the University of Texas observed a sudden change in culture during the fifteenth century, where it is appreciated that the citizens of Xaltocan, and suddenly they disappear, finding only vestiges of the Aztecs.
In just 40 years, the city passed from Otomi hands to Aztec possession, the place was repopulated by them in 1435, a rather strange fact since there is no evidence that the Otomi settled in other lands, or were exterminated.
Thanks to this arduous investigation, based on the genetics observed in the mitochondria samples extracted from DNA, it has been proven that some Otomi did not leave their home, and they mixed with this new culture. The elements studied were collected from 25 bodies found in various excavations at Xaltocan.
Since the mitochondrion of DNA is inherited only from mothers to children, to complete the study and solve the new enigmas posed, research will be necessary that focuses on a cell that men can delegate.
The details of this study on genetics have been published in the American Journal of Physical Anthropology, which helps to shed some light on the enigma of disappearance of the Otomí culture. The tests are heading towards the idea that they did not disappear completely. The DNA of the bodies dating from the year 1240, the date on which it is proven that they inhabited Mexican soil, and the one extracted from 1521, show certain similarities.
Probably the invading people mixed with the already settled and the result was the appearance of a new cultural line. Over time the Otomi vestiges disappear.
As countless findings reveal, the Aztec empire was formed thanks to the union of many peoples who lived together in what is now the Mexican country, which in 1428 were grouped in the denomination of Triple Alliance. We now know that the Otomi also participated in the writing of the history of the Aztecs.
I study journalism and law, and for both subjects history is fundamental. It is the basic pillar of our life. As a mother I try to introduce my son to the roots of our origin. I love to tell you stories about how our ancestors lived and interesting anecdotes that pique your curiosity. An exciting world that we will learn together here in Redhistoria.
