Evolution of Cannabis: A Gift of Nature to Humankind

Cannabis has gratified an abstruse role in the phase of human antiquity. The saga of human-Cannabis relationships has been a long, drawn-out affair, an epic association of people and a plant that has influenced history on many fronts in various regions of the world.

Hypotheses of foundation and dispersal based on archaeological0 and historical data are confirmed by botanical observations of Cannabis’s grass phenotypes and seed analysis. Until the late nineteenth century, Cannabis gene pools largely evolved independently of one another as a result of geographical, human cultural, and/or agricultural isolation. During the twentieth century, diverse Cannabis gene pools were introduced into Europe and North America

Origin and evolution:

Cannabis is particularly accomplished at naturalizing to a range of temperature and subtropical climates. Cannabis sativa or narrow-leaf hemp is found today growing as a weed along streams, effluent ditches, and in farm fields across temperate continental areas of North America where it was introduced from Europe in the seventeenth century. De Candolle (1967) explains that Cannabis occurs “wild” only south of the Caspian Sea, in Siberia near the Irtysh River, and in the Khirgiz Desert beyond Lake Baikal; additionally, he proposed that it was first cultivated in southern Siberia. The Indian Hemp Drugs Commission Report (1893–94; see Kaplan 1969) analyze a broad area encompassing the southern Himalayan foothills from Kashmir through Nepal and northeastern India as the region of spontaneous growth.

We know that the original angiosperms apparently evolved more than 140 million years ago when early humans appear to have evolved into Homo sapiens in Africa about 200,000 years ago and AMHs generate broadly conquered the Middle East during the uppermost Paleolithic about 45,000 to 40,000 years ago. 8,000 years ago, an enormous expanse of northern Eurasia had a commodious temperate climate for supporting climax broadleaf and delegate woodland greenery cover and allowing Cannabis to reproduce. We ascertain that humans enlarge Cannabis easily via their hunting and union actions and ultimately introduced it into their new agricultural settlements.

Variety & Earliest Uses of Cannabis:

“Marijuana” and “hashish” are common names for differing psychoactive Cannabis products. Hashish is a mechanically extracted, concentrated resin gland preparation. Seeded marijuana is merely the dried inflorescences from THC-bearing varieties of Cannabis. The popularity of hemp products has continued to grow as new uses arise in the fibre and food industries. Hemp products constitute a strong presence in international markets, and the hemp industry continues to grow, driven by the realization of Western consumers that hemp provides sensible alternatives to mainstream products. Since 1990, industrial hemp production has increased in many parts of the world resulting from both the rediscovery of traditional uses and the invention of new ones.

People have long been fascinated to Cannabis for its distinctive useful products— fibre, food, and drugs—some for economic reasons and others maybe for spiritual purposes. Some simple hypotheses can be advanced that also bear on the later evolution of Cannabis under human selection. “Cannabis sativa” was first used for its fibre and is “one of the oldest cultivated non-food crops.” Cannabis was certainly among the very first cultivated fibre and drug plants and thus provided a primary source of fibre and seed oil to northern temperate cultures for millennia. The use of wild Cannabis most likely predates the dawn of agriculture. Cannabis, the notorious provider of mind-altering Δ9-tetrahydrocannabinol (Δ9-THC) and other psychoactive substances, has been utilized for many purposes in addition to its common use as a religious and recreational drug plant. Its stalks can be used as a fuel source. Its nutrient-rich seeds feed humans and domesticated animals; the seed oil was also used for cooking and burning as lamp fuel. And of course, Cannabis has many medicinal applications.

Legalization:

In some places, the political conditions surrounding medical Cannabis legislation has become more informed, compassionate, and moderate. The localized approval of medical Cannabis use in many regions has blurred the line between recreational enjoyment and medical need, and marijuana and hashish use are de facto legal in parts of North America and Europe. However, in most of the world, recreational and medical Cannabis is only safely grown and used in the privacy of one’s own home. Now the United States has become a major marijuana supplier and use is higher than ever, while foreign governments search for differing legal solutions to their own situations.
