About 28 million years ago, a small plant emerged on the slopes of the ancient Tibetan Plateau that was destined to change the course of human history.
Cannabis is one of the most mysterious and controversial plants on Earth, and its evolutionary history is far more astonishing than you might imagine.
In this video, we'll explore the complete evolution of cannabis: from its origins in the high steppes of Asia to its emergence as a companion plant 12,000 years ago—long before wheat, corn, and potatoes. You'll learn how plate tectonics literally created the conditions for this plant's emergence, why cannabis and hops (the basis of beer brewing) turned out to be genetically related, and how a groundbreaking 2021 study involving whole-genome sequencing has revolutionized scientists' understanding of marijuana's origins.
But the most intriguing question is: why is cannabis capable of altering our consciousness? The answer lies in the endocannabinoid system, an ancient biological network that has existed in animals for 600 million years—we even share it with sea urchins.
A plant that evolved to protect itself from UV rays and herbivores accidentally created a molecule that perfectly fits receptors in our brain. We'll talk about the Scythians and Herodotus, ancient rituals in the Chinese mountains, the secret breeding of cannabis in 20th-century basements, and how humans turned the plant's defense mechanism into a source of pleasure.
This is a story about how geology shapes biology, and biology shapes culture.
