Our DNA It doesn’t come from where we thoughta University of Granada study reveals we have more in common with Norwegians than we thought. DNA is that book of instructions that determines our entire being. Its discovery completely changed some investigations, but it also became a source of data that took us to the origin of humanity. We can know exactly where we come from and what elements we share with the people who have inhabited the earth for centuries.
In Spain we have been the cradle of cultures and civilizations that have spread throughout the territory. We are a land that welcomes other people from far away who will eventually become one of those who make us pay attention to everything that is happening around us. Therefore, perhaps this recent study will end up giving us more information about what we are and were in the past, this mixture of elements that is here to stay and which gets richer as we go along. time passes and we discover other elements that we did not have until now. imagined.
Spanish genetics turned upside down
Now is the time to start preparing for what is to come and what we may encounter in the days ahead. Our DNA is a letter that makes us describe not only our own body, but also those who preceded us in those genes that are present, but that we do not see.
We Spaniards have greater genetic wealth than we imagine. We are the gateway to Europe and this means that we will have to be aware of certain elements that we may not have considered until now. Now is the time to put some key elements into practice.
Our researchers did not hesitate to discover first-hand what we may be facing, with some fundamental details that we may not have even imagined until now. We will need to know at all times what awaits us and how to deal with it.
It’s time to find out what this Spanish genetics hides that could end up giving us signs of changes, more than we imagine. It’s time to bet clearly on those details that we may not have even imagined until now.
Our DNA doesn’t come from where we thought it did
THE The University of Granada revealed to us that we have DNA it comes from a part of the world we didn’t expect. Despite the proximity to Africa and the historical links that we have maintained, we are confronted with a series of revelations that make our hair stand on end.
Following an article from this aforementioned University: “Without ‘Out of Africa’: a genetic study reveals that the population of the south of the Iberian Peninsula has practically no African DNA.”
A statement that explains itself: “Researchers from the University of Granada (UGR), belonging to the Genetic Identification Laboratory, have discovered that the Y chromosome DNA of populations from the south of the Iberian Peninsula (Granada, Malaga and Almería) has a very small component of DNA from North Africa, similar to that which exists in other places in Spain and other Mediterranean countries. These results, published in the prestigious Scientific Reports (from the Nature group), reveal that, despite the fact that the Arabs occupied the Iberian Peninsula for more than 800 years, they did not leave more genetic heritage in these Spanish provinces than in other regions. where they spent much less time. This is the first time that a specific study of these three Spanish populations (provinces) on the genetic markers of the Y chromosome has been published, and it is compared with the rest of Spain, Europe and North Africa . Researchers warn of the strong contrast that exists between the genetic heritage left by the Arabs in the Iberian Peninsula, which now appears rare, and the enormous cultural heritage, if we consider the great Andalusian heritage.
Continuing with the same explanation: “The similarities between the population of Granada, Malaga and Almería and the European population, or more specifically other Spanish populations, make it very difficult to identify possible existing differences, despite the fact that the Y chromosome is one of It is the smallest chromosome in the human genome, approximately 60 MB (million bases) in size, and is inherited directly from parents to children. By genetically characterizing variations of the human Y chromosome, it is possible to build a tool to understand the genetic contribution of these variations and their evolution. This information can be applied to different scientific fields, such as anthropology, forensics and many others in biomedicine. In the study carried out at the UGR, male individuals from the populations of Granada, Málaga and Almería were genetically characterized to determine the possible genetic inheritance of the populations that formed the ancient kingdom of Granada present in current populations. “Our results reveal that no African component remained in the population of the southern Iberian Peninsula, despite its occupation for 800 years,” says Saiz. The presence of typically African haplogroups in the population of Granada, Malaga and Almería is not significant compared to their frequencies in European populations, both Mediterranean and Northern European.
