The latest maps of independent origins of farming illustrate that agriculture did not emerge from a single “fertile crescent” in Southwest Asia, but from multiple independent centers of domestication spread across various continents. Publications that say otherwise in 2024 are no longer supported by current research. These independent regions contributed to the cultivation of a wide range of plants and animals, fostering distinct agricultural practices and diets worldwide.
From the Americas, agriculture focused on the domestication of crops like maize, cassava, beans, potatoes, cocoa, pumpkins, tomatoes, and chillies. Specifically, in North America, crops like artichokes, blueberries, cranberries, and sunflowers were domesticated, contributing to regional diets long before the Columbian exchange. Meanwhile, in South and Central America, maize, beans, and squash formed the backbone of many ancient American civilizations. Sweet potatoes, cassava, and cacao were also major crops, contributing to the complexity of diets in the Andean and Mesoamerican regions. This diversity contradicts the notion that staple crops such as wheat and barley dominated global agriculture.
In Africa, domesticated plants reflect a regional adaptation to different climatic and ecological zones. West African agriculture focused on crops like yams, melons, black-eyed peas, oil palm, and various millets, demonstrating the continent’s rich agricultural heritage. East Africa also contributed to global agriculture with crops such as coffee and teff, while animals like the donkey and dromedary camel played crucial roles in transportation and farming. These 2,000 crops and animals were cultivated and managed long before external influences from Eurasia reached Africa, indicating a rich, independent agricultural tradition.
Asia provides yet another example of multiple centers of crop domestication. In Southeast and East Asia, early farmers domesticated rice, millet, soybeans, and mung beans, while also managing animals like pigs, chickens, water buffalo, and ducks. The diversity of plant and animal life in these regions, from taro and bananas in Southeast Asia to buckwheat and cabbage in Central China, challenges the notion that agriculture spread from a single origin in the Levant. Instead, these centers reflect unique ecological conditions and evolving agricultural practices.
The Mediterranean, Southwest Asia, and Europe also represent agricultural innovation beyond the confines of the “Fertile Crescent.” While it is true that early farmers in Southwest Asia cultivated wheat, barley, and lentils, the domestication of dates, olives, and grapes demonstrates the variety of crops that emerged even within this region. In Europe, crops like oats and rye developed, adapted to the cooler climates of the continent, while pigs, cattle, and sheep were domesticated to support early agrarian societies.
The notion that the Fertile Crescent is the sole cradle of agriculture has long been abandoned by informed researchers in favor of a more nuanced understanding. The maps demonstrate that agriculture began independently across various ecosystems. These regions, adapted to local conditions, led to the domestication of a wide range of crops, many of which were perfectly suited to their local environments. For example, African sorghum, black-eyed peas and millet evolved in drier climates, while maize and potatoes in the Americas adapted to high-altitude and tropical conditions.
The timing and spread of farming were deeply influenced by the interaction of climate, geography, and environmental conditions. In regions where reliable rainfall or water sources were present, such as near large lakes in Africa or river valleys like the Tigris, Nile, Niger, India Valley, and Euphrates, farming could take root more easily. However, environmental variability, such as the desiccation of the Sahara or glaciation in Europe, shaped when and how populations adapted to agricultural practices. In areas facing significant climatic challenges, such as drought or extreme cold, populations were forced to adopt a diverse approach—combining farming with other subsistence strategies like pastoralism, proto-agriculture for new plants when migrating into new unfamiliar regions, fishing, hunting, and foraging. This mixture of food production methods highlights the flexibility and resilience of early human societies in response to changing ecosystems. In some cases, these pressures delayed the full adoption of farming, while in other regions, they spurred innovation, leading to the domestication of crops and animals that were well-suited to local conditions.
Additionally, the variability of ecosystems meant that different plants and animals were domesticated in different ways. A diversity of calendars starting at different times of the year had to be created from continent to continent, and region to region within continents. In many cases, humans initially managed wild plants or animals in what is called a “proto-agriculture” phase. This management could lead to full domestication when climatic conditions allowed, but in some cases, such as in the Sahara, dramatic ecological shifts forced populations to remain nomadic pastoralists rather than farmers, or various populations practicing multiple methods of food production—combining and mixing farming domesticated plants, proto-agriculture for new plants in new unfamiliar regions, fishing, hunting and pastoralism.
In conclusion, the process of agricultural domestication was far more global and diverse than once thought. Independent centers of plant and animal domestication emerged across all continents, each contributing to the development of agriculture. The timing of farming’s adoption was influenced by environmental factors, with various regions transitioning to full agriculture at different times depending on the interaction of climate, geography, and available plant and animal species.
