Studies of pollen, plant remains, and the bones of animals and humans reflect significant shifts in food sources, notably the transition from hunting and gathering to farming (sometimes called the Neolithic Revolution). Biomolecular analysis of bones and other organic remains is providing new knowledge about diet and health, and ancient DNA is shedding new light on the domestication of plants and animals and on human migrations. Scientific analysis has also stimulated experimental...

The earliest geographic range of cannabis ( Cannabis indica , C. sativa ) is uncertain, but the plant's euphoric properties were apparently known as early as the Neolithic Age in Europe, and cannabis usage is documented in the ancient civilizations of Mesopotamia and the Indus River Valley. Some authorities believe cannabis was the divine soma plant of the Aryan culture in India and Central Asia. The stimulant khat ( Catha edulis ) is widely...
