The research traces the origins of the cannabis plant 28 million years ago on the Tibetan Plateau



A fascinating new study, published in the journal Vegetation History and Archaeobotany on May 14, details the work of a research team from the University of Vermont, providing evidence that the cannabis plant has developed 28 million years ago in a specific area on the Tibetan Plateau. "

The study, titled" Cannabis in Asia: Origin and Early Cultivation Based on a Synthesis of Subfossil Pollen and Archaeobotanical Studies ", aimed to establish the oldest common ancestor of the cannabis plant. Under the direction of John McPartland of the University of Vermont, the research team analyzed data on the distribution of wild-type plants, including 155 studies on fossil pollen.

Anxious to determine the unknown origins of the modern cannabis plant, which has been known to thrive in dry steppe-like conditions caused by the tectonic formation of the northeastern Tibetan Plateau near Qinghai Lake about "28 million years ago" were caused. This corresponds to the first steppe community that has developed in Asia, the team said with cannabis pollen visually resembles the hop pollen. The researchers have distinguished both species and found that hops and cannabis share a common ancestor.

Where has the cannabis plant taken root?

Humans have used cannabis plants for at least 27,000 years. This new study provides a broader understanding not only of when the first cannabis plants developed, but also of when humanoids began to use them as medicines and in ritual environments. A Live Science article states, "While it has long been believed that this medicinal and psychotropic plant developed in Central Asia for the first time, scientists were uncertain about their exact location."

The central source of origin in this new publication Cannabis is only a few hundred kilometers away from the Baishiya Karst Cave, which researchers recently announced in an article by New Scientist once inhabited by an elderly relative of Homo sapiens, the Denisovans. DNA testing revealed that a jawbone found in this Tibetan cave came from a Denisovan. And now the oldest traces of cannabis have been found in or around the same area.

It is thought that "in the middle of the Ice Age, the earth transported cannabis seeds from another location," supported by cannabis pollen discovered in other Denisovan-inhabited caves.

Modern flowers with ancient origins

According to another article from Live Science, cannabis reached Europe about 6 million years ago and had spread to eastern China 1.2 million years ago. Over the millennia, cannabis migrated all over the world, passing through Africa to South America in the early 1900s, where Mexican immigrants fled the 1910-1911 Mexican Revolution.

After 28 million years of growth and nearly 30,000 years of proven use by humans Cannabis sativa L . and Cannabis sativa were banned in Utah in 1915, and until 1931 it was illegal in 29 states. Until 1937, the marijuana tax law imposed cannabis on the Drug Enforcement Agency's regulation and criminalized possession of the plant across the country.

At the beginning of this century, however, these laws collapsed under pressure from the American people, and according to Business Insider's report "The legalization of marijuana is going through the States". It seems that while the richest and most technologically advanced country in the world brings our future, there remains a hardcore population that prefers the old methods, the Denisovan method, in which the magical plant is a dietary one social staple food was.
