The Neolithic period, often referred to as the New Stone Age, marked a significant transformation in human history, fundamentally changing how people acquired and consumed food. This era, beginning around 12,000 years ago, saw a gradual shift from a nomadic hunter-gatherer existence to a settled lifestyle based on early agriculture and animal domestication. This dietary revolution, moving towards deliberate food production, laid the groundwork for future societal developments.
The Agricultural Revolution
The shift from hunting and gathering to settled agricultural practices defines the Agricultural Revolution, a profound change that began around 10,000 to 12,000 years ago. This transition emerged independently in various parts of the world, with a primary center of origin in the Fertile Crescent, a region in the Middle East.
The warming trend after the last Ice Age, around 14,000 years ago, fostered the growth of wild wheat and barley, setting the stage for cultivation. This, alongside population growth, encouraged people to find more reliable food sources. Farming tools, crop breeding, and animal domestication allowed for a consistent food supply, enabling permanent settlements and supporting larger populations.
Staple Plant-Based Foods
The Neolithic diet saw staple plant-based foods become central to human sustenance, driven by the systematic cultivation of crops. Cereals were particularly important due to their high nutritional value and ability to be stored for extended periods. In the Fertile Crescent, early domesticated grains included emmer wheat, einkorn wheat, and barley.
Beyond these, other cereals like rice and millet were cultivated in Asia, with archaeological evidence of rice paddies in China dating back at least 7,700 years. Legumes also formed a significant part of the diet, with lentils, peas, and chickpeas being among the first domesticated pulses. Flax was another early cultivated plant, valued for both its fibers and oil-rich seeds.
Animal-Based Foods and Their Role
Domesticated animals played a significant role in supplementing the plant-based diet of Neolithic communities. Cattle, sheep, goats, and pigs were domesticated, providing meat and secondary products like milk. The earliest domestication of livestock occurred in Mesopotamia between 10,000 and 13,000 years ago.
Archaeological evidence from Neolithic ceramics indicates cheesemaking was practiced in Late Neolithic Poland, using milk from various animals. Early farmers processed milk into products like cheese or yogurt. Hunting and fishing also continued to supplement the diet, providing diverse protein sources.
Preparation and Preservation Techniques
Neolithic people developed various techniques to process and preserve their food, enabling year-round sustenance. Grinding grains into flour was a fundamental practice, often performed using querns. Early querns, known as saddle querns, involved rubbing a handstone back and forth over a stationary stone slab.
The flour was used to make early forms of bread, with evidence suggesting bread-making dates back over 14,000 years, predating widespread agriculture. Fermentation was also employed, particularly for dairy products like cheese and yogurt. Other preservation methods included drying, salting, and potentially smoking, which helped store food for longer periods.
Dietary Impact and Health
The shift to a Neolithic diet had notable effects on human health. While agriculture provided a more consistent food supply, supporting population growth, it also introduced new dietary patterns.
Reliance on a narrower range of staple crops, particularly cereals, could lead to nutritional deficiencies compared to the more varied hunter-gatherer diet. For example, iron deficiency likely became more common due to reduced nutrient bioavailability in cereal-heavy diets.
Dental health also changed significantly; while tooth wear decreased due to softer foods, increased carbohydrate consumption led to a rise in dental caries (cavities).
Living in denser, settled communities and close proximity to domesticated animals increased exposure to pathogens. This contributed to the emergence and spread of zoonotic diseases, such as brucellosis from goats, impacting human and animal health.
