Mark Merlin , an ethnobotanist and cannabis historian at the University of Hawaii at Manoa, says the wide diversity in cannabis around the world today is a testament to how long people have been involved with the plant and harnessed its many uses.

In fact, the human cultivation of cannabis had such a strong effect on the genetic evolution of cannabis that researchers suggested the pure wild ancestors of cannabis sativa have gone extinct.
Therefore, the human hand may have effectively engineered the most controversial plant into existence. Why it matters — Due to the controversial and illicit nature of cannabis, which remains illegal in many countries and states in the U.
This study takes a remarkable first step in tracing the evolutionary origins of modern cannabis, especially at a time when many lawmakers are reconsidering whether or not to legalize the drug. Through their research, the scientists were able to trace the genetic differences between hemp and psychoactive cannabis, with differences in gene sequences that code for the cannabinoid CBD in hemp and THC in other strains, respectively.
Although the scientists found genetic divergence in the expression of THC and CBD genes in all cannabis strains studied, they also found five hemp samples that contain more genetic complexity than we previously thought. The evolutionary findings challenge the traditional legal divide between hemp and pot, suggesting it might be more arbitrary than scientific in reason.
