Lack of vital microelements, such as iodine, magnesium and iron, can affect human evolution, leaving Hetq in our DNA. This conclusion was scientists from the University College of London (UCL). The results of the study were published in the magazine of "American Genetics" (AJHG).
Scientists have analyzed 276 genes associated with 13 main minerals, including zinc, selenium, calcium and potassium. Scientists have noticed changes in genes related to their absorption or among the population less than the population.
The genes responsible for the development of these materials were made to a positive choice. This means that the natural choice has preferred the options for genes that help the body to better overcome the mineral imbalance.
For example, genetic adaptations of receptors hanging from iodine have been found near the people of the Central African Mbut, a short group of Iodine deficiency lands. Similar changes have been found in the Mayan of Central America. In these areas, a relatively low prevalence of the magnification of the thyroid gland was also registered. Scientists believe that a reduction in height may be a part of the defensive adaptation to the lack of iodine.
In South and Central Asia, where lands may contain excess magnesium, changes in FXYD2 and Mecom genes related to magnesium absorption have been found. These mutations may have reduced the risk of toxicity, limiting the absorption of the element.
"In almost all studied populations, we have discovered evidence of adaptation to at least one mineral," said the head of the project Jasmine Ris. "This implies that microelements have been an important evolutionary factor through human history."
