1. When Did Humans Start Cooking Food?
Humans likely started cooking food around 400,000 to 2 million years ago. While pinpointing an exact date is challenging due to the scarcity of physical evidence, the controlled use of fire for cooking marks a significant turning point in human evolution, profoundly influencing our biological and social development.
The absence of extensive physical evidence suggests that early humans made minimal modifications to fire control and cooking techniques for hundreds of thousands of years. This is quite astonishing, considering their concurrent advancements in hunting tools and the emergence of cave art around 64,000 years ago. Initial cooking methods likely involved placing food on heated stones.

2. What Were the Earliest Cooking Methods?
The earliest cooking methods included roasting food directly over fire and heating food on hot stones. These simple techniques laid the groundwork for more advanced culinary practices.
Around 30,000 years ago, “earth ovens” emerged in central Europe. These were large pits dug into the ground and lined with stones. Hot coals and ashes heated the stones, and food, likely wrapped in leaves, was placed on top, then covered with earth for slow roasting. Bones from various animals, including mammoths, have been discovered in and around these ancient ovens, indicating a significant improvement over rapid roasting.
Slow cooking in earth ovens allowed the collagen in tough connective tissue to break down into gelatin, making the meat more tender, flavorful, easier to chew, and digest. This process requires several hours or longer, depending on the animal’s age and the meat’s origin. Cuts like shoulders and hindquarters, which have more connective tissue, benefit significantly from slow cooking, similar to modern barbecue methods.
3. What is Wet Cooking?
Wet cooking, or boiling, involves cooking food in water, which proved advantageous for starchy root tubers and rendering fat from meat.
Archaeological findings suggest that smaller earth ovens lined with hot stones were used to boil water for cooking meat or root vegetables as early as 30,000 years ago, during the Upper Paleolithic period. Some researchers propose that water was boiled in perishable containers, such as those made from bark, wood, or animal hides, placed either over the fire or directly on hot ashes or stones, well before this time. This is plausible because even flammable containers can withstand open flames as long as liquid inside dissipates the heat through evaporation.
Evidence of sophisticated cooking utensils appears around 20,000 years ago with the advent of fired clay pottery. Chemical analysis of pottery shards found in Japan reveals fatty acids from marine sources, indicating that these heat-resistant pots were used to boil seafood.
4. Why Did Cooking Methods Evolve So Slowly?
The slow evolution of cooking methods can be attributed to the nomadic lifestyle of early humans, who were constantly on the move in search of food.
Jacob Bronowski, in his book The Ascent of Man, suggests that early nomads, such as hunter-gatherers, were perpetually searching for food, leaving little time for innovation. Their daily life revolved around survival, with each day resembling the last and each morning signaling the start of another journey. The constant movement made it impractical to carry heavy cooking utensils, even if they had been invented.
Around 10,000 years before the last ice age ended, creativity and innovation began to flourish as the climate warmed, making food more readily available. This allowed early humans to gather food more easily and reduce their need to move constantly.
5. How Did the Agricultural Revolution Impact Cooking?
The Agricultural Revolution, beginning around 12,000 years ago, profoundly impacted cooking by enabling settled lifestyles and fostering innovation.
The discovery that seeds from wild grasses, such as emmer wheat and two-row barley, could be gathered, saved, planted, and harvested the following season marked the dawn of agriculture. This transformation first occurred in the Fertile Crescent, encompassing regions of Jordan, Syria, Lebanon, Iraq, Israel, and parts of Iran. The ability to harvest enough food in just three weeks to last an entire year transformed nomadic life into sedentary living.
Settling in one place necessitated the construction of immovable structures for food storage and protection, leading to the establishment of permanent settlements. This agricultural revolution subsequently spread to other parts of the world over several millennia.
6. What Role Did Domestication Play in Early Cooking?
Domestication of plants and animals played a crucial role in the development of new foods and cooking methods.
Pioneering research by Russian scientist Nikolai Vavilov in the 1930s and American scientist Robert Braidwood in the 1940s revealed that people in seven independent regions of the world domesticated crops and animals indigenous to their regions over several thousand years. Vavilov’s research was unfortunately cut short when he was imprisoned in 1940 for his evolutionary views.
Around 12,000 years ago, as the ice age ended, early humans in the Fertile Crescent were harvesting wild wheat and barley in quantity, but there was no evidence of domesticated plants and animals. Within approximately 300 years, between 10,000 and 9,700 years ago, the first signs of domesticated plants and animals began to emerge in the southern Jordan Valley, near the ancient settlement of Jericho.
During this brief period, seeds of plants like wheat and barley grew larger, while the bones of animals became smaller. This is because early humans selected larger seeds for planting, which stored more nutrients for faster growth. They also chose wheat plants with terminal clusters of seeds that retained kernels during harvest, rather than scattering them in the wind like wild varieties. Similarly, domesticated goats and sheep were selected for docility and adaptability to confined living, leading to their smaller size. These changes reflect the deliberate genetic modification of plants and animals through human intervention.
7. How Did Permanent Settlements Change Cooking Practices?
The shift from nomadic life to permanent settlements enabled significant advancements in cooking technology and practices.
The change to a settled lifestyle allowed humans to make significant achievements in technology and other areas. Small farming villages grew into larger permanent settlements and then small cities within a few thousand years. Jericho stands as one of the oldest permanent settlements, offering a detailed record of agricultural development between 10,000 and 9,700 years ago. Originally settled by hunter-gatherers around 11,000 years ago near a spring-fed oasis, early excavations revealed no signs of domesticated seeds or animal bones.
By 9,700 years ago, domesticated seeds of emmer wheat and barley began to appear, and the farming settlement had expanded to about 6 acres, housing approximately 300 people in mud-brick houses. By 8,000 years ago, Jericho had grown into a permanent agricultural settlement of around 3,000 people occupying 8–10 acres. Around this time, emmer wheat hybridized with a wild grass to produce bread wheat, containing higher levels of gluten-forming proteins essential for making leavened bread, marking the emergence of wheat in the form we still use today.
8. What are the Nutritional Benefits of Cooking Food?
Cooking food unlocks essential nutrients, making them more accessible and digestible, thus significantly enhancing our nutritional intake.
Cooking breaks down complex starches and proteins, rendering them easier for our bodies to digest. For example, cooking meat denatures proteins, making them less resistant to digestive enzymes. Similarly, cooking vegetables softens plant cell walls, releasing vitamins and minerals that would otherwise remain trapped.
Furthermore, cooking eliminates harmful bacteria and toxins present in raw foods, mitigating the risk of foodborne illnesses. This is especially crucial for meats and certain plants containing natural toxins that are neutralized through heat. The increased bioavailability of nutrients and reduced health risks have been pivotal in supporting human development and population growth.
9. How Has Cooking Influenced Human Evolution?
Cooking has played a pivotal role in human evolution by reducing the energy required for digestion and allowing for the development of larger brains.
The “cooking hypothesis” suggests that the advent of cooking allowed early humans to obtain more energy from their food, leading to significant biological adaptations. Cooked food is easier to chew and digest, reducing the energetic demands on our digestive system. This energy surplus was then redirected towards brain development, resulting in larger and more complex brains capable of advanced cognitive functions.
Additionally, cooking expanded the range of edible foods, enabling early humans to consume a wider variety of plants and animals. This dietary diversification provided a more balanced intake of nutrients, further supporting overall health and development. The combined effects of increased energy availability and dietary diversity have been fundamental in shaping human evolution.
10. What is the Future of Cooking?
The future of cooking is likely to be shaped by technological advancements, sustainability concerns, and a deeper understanding of nutrition.
Advancements in cooking technology, such as precision cookers, smart ovens, and automated cooking systems, are making it easier to prepare healthy and delicious meals. These innovations can help home cooks achieve professional-level results with minimal effort.
Sustainability is also becoming an increasingly important consideration in cooking. Chefs and consumers are seeking ways to reduce food waste, use locally sourced ingredients, and adopt more environmentally friendly cooking methods. Plant-based diets are gaining popularity, driven by concerns about the environmental impact of meat production.
Finally, a deeper understanding of nutrition is leading to more personalized approaches to cooking. People are increasingly aware of how different foods affect their health and are tailoring their diets to meet their individual needs. This trend is likely to continue, with personalized nutrition becoming a mainstream concept.
