The origin of agriculture marks a significant turning point in human history. While the exact details of how agriculture began are not fully known, researchers have proposed several theories based on archaeological evidence and studies of early human societies.
One widely accepted theory is called the Neolithic Revolution or the Agricultural Revolution. It suggests that around 10,000 to 12,000 years ago, in multiple regions around the world, humans transitioned from a hunter-gatherer lifestyle to settled farming communities.
The process of agricultural development likely occurred gradually and differed in various regions. Some key factors that contributed to the emergence of agriculture include:
1. Transition from Nomadic to Sedentary Life: As populations grew, some hunter-gatherer groups started settling in one place for longer periods. This shift was influenced by the availability of resources and favorable environmental conditions.
2. Domestication of Plants and Animals: Humans began to intentionally cultivate and breed certain plants and animals. They selected desirable traits, such as larger seeds or docile behavior, and gradually transformed wild species into domesticated varieties that were more useful for their needs.
3. Development of Agriculture Techniques: Early farmers experimented with different techniques, such as clearing land for cultivation, irrigation, and planting crops in organized patterns. These practices improved crop yields and facilitated the growth of agricultural societies.
4. Environmental Factors: Environmental changes, including climate variations and the end of the last Ice Age, may have influenced the availability and distribution of wild resources. These changes could have prompted humans to seek more reliable food sources through cultivation.
5. Social and Cultural Factors: The shift to agriculture brought about changes in social structures and cultural practices. People settled in communities, leading to the development of permanent settlements, division of labor, and the emergence of complex social hierarchies.
Overall, the development of agriculture was a transformative process that allowed humans to transition from a nomadic, subsistence-based lifestyle to settled communities with surplus food production. This shift provided the foundation for the growth of civilizations, the development of advanced technologies, and the shaping of human societies as we know them today.
Sometime around 12,000 years ago, our hunter-gatherer ancestors began trying their hand at farming.
First, they grew wild varieties of crops like peas, lentils and barley and herded wild animals like goats and wild oxen. Centuries later, they switched to farming full time, breeding both animals and plants, creating new varieties and breeds. Eventually, they migrated outward, spreading farming to parts of Europe and Asia.
The earliest farmers lived in the Fertile Crescent, a region in the Middle East including modern-day Iraq, Jordan, Syria, Israel, Palestine, southeastern Turkey and western Iran. And scientists had long assumed these early farmers were a homogenous group that traded and intermingled, swapping farming tools and tricks — as well as their genes. In other words, farming was long believed to have been started by one group of ancestral humans.
But a new study suggests something different — that multiple groups of people in the Fertile Crescent started agriculture, and these groups were genetically distinct from one another. That is, they didn't intermingle at the time, at least not for a few thousand years. "They lived more or less in a similar area, but they stay highly isolated from each other," says Joachim Burger, an anthropologist at the Johannes Gutenberg University Mainz, in Germany, and co-author of the new study.
Burger and an international team of scientists analyzed ancient DNA from the remains of four individuals who lived about 10,000 years ago on the eastern edges of the Fertile Crescent — the Zagros Mountains on the border between Iraq and Iran. They compared the DNA of these individuals with that of skeletons that were a couple of thousand years younger and had been found way on the other end of the Fertile Crescent.
