An international team of scientists collected 110 complete genomes of different types of cannabis and came to the conclusion that this plant was first domesticated about 12 thousand years ago in China.
The work was published in the journal Science Advances. The genomic history of cannabis is not well understood due to legal restrictions. Nevertheless, not only narcotic substances are produced from this plant, but also important medicinal compounds and textiles are obtained.
The cultivation of cannabis has a long and confusing history associated with the economic, social and cultural aspects of the development of civilization.
Scientists from the universities of Lanzhou (China), Lausanne (Switzerland), Qaid-i-Azam (Pakistan), Qatar (Qatar) and Oxford (UK) studied 110 cannabis samples from around the world and, using whole genome resequencing, were able to learn more about the history of domestication of the plant …
It turned out that the first domestication of hemp was in the early Neolithic, 12 thousand years ago. This happened in East Asia, namely, on the territory of China. All other varieties of this species of wild plants diverged around the world directly from here.
As a result of selection, ancient agronomists managed to obtain tall bushes with unbranched erect stems, which contain a large amount of plant fibers in the main "trunk" and low bushy stems with a large number of flowers necessary for the production of narcotic and medicinal substances.
