North Africa is the result of a multitude of migrations as a result of its strategic position between three continents: separated from the rest of Africa by the Sahara desert, united with Europe through the Mediterranean, and connected with the Middle East through the peninsula. Arabic. The constant migrations over thousands of years have caused the genetics of its inhabitants to be very heterogeneous. Now, researchers from the Institute of Evolutionary Biology ( IBE ) in Barcelona, ​​a joint center of the Higher Council for Scientific Research ( CSIC ) and UPF, have published an article where they analyze the differences between Berbers and Arabs, and study large migrations at the national level. genetic. Each individual has their genetic pedigree in which you can see what percentage of DNA comes from sub-Saharan, European or Asian ancestors. In addition,

A team of scientists, led by IRTA researchers, and in which the CRAG (Center for Research in Agrigenomics) and the University of Granada have collaborated, have carried out a project Dubai Email List financed by MINECO, which is the first genetic, phenotypic study and of geographic adaptation carried out until today using traditional varieties of durum wheat from the Mediterranean. Durum wheat, which is used mainly for the production of pasta and semolina, is a typically Mediterranean crop that requires moderately dry environments with high temperature and radiation during the growth of the grains, in order to obtain optimum yield and quality. Domesticated during the Neolithic Revolution in the Fertile Crescent (Syria, Turkey and Lebanon), like bread wheat, it spread more than 10,000 years ago through the Mediterranean basin until it reached the peninsula,

leaving several varieties in its path through each region. traditional local genetically closer to wild varieties as they are closer to their center of origin. The cultivation of these traditional varieties began to decline from the second half of the 20th century as a result of the green revolution and the replacement with new semi-dwarf varieties, more productive but not genetically uniform. Despite this, the researchers are convinced that these landraces represent an important group of genetic resources that are very useful for breeding, especially in conditions of water scarcity. The researchers have evaluated in the field (phenotyping), during 3 years, a collection made up of 172 traditional varieties of durum wheat from 21 Mediterranean countries, grown together with 20 modern varieties in 6 environments in the north and south of Spain.
