Why Did Humans Begin Farming Around 10,000 Years Ago? — Here’s What Scientists Think Happened

For nearly the entirety of human existence, our ancestors were hunter-gatherers. A lifestyle that most hominin species adapted for millions of years, until about 10,000 years ago, when humans started farming. So, why did people stop hunting for food and start growing it instead in their lands?

It was one of the biggest changes in human history and has contributed greatly to who we are today. Instead of looking for food and moving around, humans planted seeds and grew crops. A shift that ignited the beginning of more complex societies with larger populations, such as villages, towns, and eventually, civilizations. So, let’s explore what led to this revolutionary step for humanity.

When Did Farming Begin?

Scientists called this great shift from being hunter-gatherers to farmers the Neolithic Revolution. It began around 11,700 to 10,000 years ago. Just about when the Ice Age that engulfed the planet ended. Before this estimated time, the modern human species, Homo sapiens, had been existing for 200,000 to 300,000 years, which meant that for more than 90% we were hunter-gatherers.

Interestingly, the transition to farming did not just happen in one place. China, certain parts of Africa, the Middle East, and the Americas all separately began the Neolithic Revolution. Cultures that had not met for thousands of years began settling down and growing food instead of hunting and gathering.

Why Did Humans Start Farming?

What Were Humans Doing 10,000 Years Ago?

Instead of just one particular reason, scientists have several ideas on why humans suddenly began settling down and planting crops about 10,000 years ago. The first and more significant reason is the warmer climate after the ice age. Not only did the temperature go up to a level suitable for farming, but it also stabilized.

This scenario also made the environment more abundant and productive, allowing hunter-gatherer groups to have the opportunity to become more sedentary and experiment with planting crops. There were even some recorded groups who started settling down, even before farming was common. The environment and climate becoming ideal to try another lifestyle was one of the biggest reasons for this change.

The second reason was intensive foraging long before the ice age ended. Before they even tried planting seeds, hunter-gatherers were already harvesting plants and animals intensively. It is a more systematic way of gathering resources, which leads to domestication and eventually gives rise to agriculture.

Some of the methods were weeding to ensure wild plants grow properly, deliberately limiting the harvest to make sure the remaining plants could reproduce, and even protecting these food sources from predators. Over time, these plants evolved together with humans. In other words, seeds that stayed in place, grew faster and easier, and had a lot more yield were chosen and domesticated.

From here on out, the jump to the actual farming was smaller than originally thought. Also, it could mean that the Neolithic Revolution was a gradual process and not a sudden end of the hunter-gatherer lifestyle.

Another reason was population density and pressure. Intensive foraging and abundance of wild sources of food could support a group of people, but only up to a certain degree. This necessity created a loop where they started leaning more into farming and agriculture to sustain more people, leading to a higher population, and therefore increasing the need for more land and farms, and then the cycle repeats until complex societies and civilizations are born.

What Changed After Farming Began?

Once farming started, hunter-gathering became rarer, and human lives were changed forever. The farmers, needing to tend to their crops and seeds, settled in the same land, creating a permanent home. After several groups, towns and villages started to be formed.

With an abundance of food, more babies survived into adulthood, the population increased, and human capital went into different aspects of life. Not everyone needed to farm all the time, so new jobs and skills were created. Some made old necessary tools, and some crafted new technology. Over time, societies become more diverse, with a lot more organization about their roles as individuals.

Additionally, with a more reliable source of food, communities expanded quickly, and people began trading with each other as they owned more items. Over time, they built bigger structures and organizations, and civilizations began to grow, filled with ambition, arts, new technology, and shared ideas.

Were There Downsides to Farming?

The Agricultural Revolution: Crash Course World History #1

Farming brought a lot of good into the world of early humans, but it also has some downsides. First and foremost is probably the hardest daily work. Before, in hunter-gatherer societies, people travelled, looked for food, and hunted. But with farming, there is constant labor, even if food is abundant at the moment. Planting, weeding, and harvesting took a lot of their time, strength, and human capital.

The diets were less diverse, as in the beginning, farmers were often planting the same crops they were familiar with over and over again. It took time until different strategies and techniques that gave birth to more varied crops were learned, but before then, their diets were thought to be less nutritious than those of hunter-gatherers.

Another downside is more infectious diseases. As communities lived together near each other and with different animals, sickness spread faster. This reason, combined with the less diverse and nutritious diet, meant early farmers had shorter lifespans compared to the hunter-gatherers.

Author's Final Thoughts

Farming began around 10,000 years ago, and our lives as human beings were forever changed. Because of a warmer climate, an increasing population, and a growing need for more stable food sources, people began to farm. They stayed in one place, planted crops, and grew more food, increased their population even more, and built the foundation that will soon give birth to the human civilization we are living in today.
