DomesticationSelective breeding of plants and animals to serve humansDogs and sheep were among the first animals to be domesticated, at least 15,000 and 11,000 years ago respectively.Rice was domesticated in China, some 9,000 years ago.Domestication is a multi-generational mutualistic relationship in which an animal species, such as humans or leafcutter ants, takes over control and care of another species, such as sheep or fungi, to obtain from them a steady supply of resources, such as meat, milk, or labor.
AgricultureCultivation of plants and animals to produce foods, fibers, fuels, and raw materialsModern agriculture: a center pivot irrigation system on a fieldAgriculture is the practice of cultivating the soil, planting, raising, and harvesting both food and non-food crops, as well as livestock production. Broader definitions also include forestry and aquaculture.
Hunter-gathererPeoples who forage or hunt for most or all of their foodA painting by Pierre Barrère of a Kalina hunter-gatherer couple in French GuianaCentral African foragers in the Congo Basin in August 2014A hunter-gatherer or forager is a human living in a community (or according to an ancestrally derived lifestyle) in which most or all food is obtained by procuring naturally occurring edible items from the local wildlife and vegetation via hunting, fishing and/or gathering fruits, seeds and other plant parts (collectively known as vegetables) as well as edible fungi such as mushrooms.

The Neolithic saw the invention of agriculture.The Neolithic (from Greekνέοςnéos 'new' and λίθοςlíthos 'stone'), or New Stone Age, is an archaeological period, the final division of the Stone Age in Asia, Europe and Africa (c. 10,000 BC to c. 2,000 BC).
NomadNomads are communities without fixed habitation who regularly move to and from areas. Such groups include hunter-gatherers, pastoral nomads (owning livestock), tinkers and trader nomads. In the twentieth century, the population of nomadic pastoral tribes slowly decreased, reaching an estimated 30–40 million nomads in the world as of 1995.

PlantPlants are the eukaryotic organisms that constitute the kingdom Plantae (/'plænteɪ/). They are predominantly photosynthetic or came from photosynthetic ancestors, meaning that they obtain their energy from sunlight by using the green pigment chlorophyll in their chloroplasts to produce sugars from carbon dioxide and water. Over the course of time, some plants have evolved to be parasitic, meaning they take energy from other organisms.
SedentismTransition from nomadic lifestyle to a society that remains in one place permanently In anthropology, sedentism (sometimes called sedentariness; compare sedentarism) is the practice of living in one place for a long time. As of 2026, the large majority of people belong to sedentary cultures.
CropA crop is a plant or plant product harvested for human use. Crops are cultivated at scale to produce food, fiber, fuel, and other products. Crops have been central to human civilization since the first agricultural revolution, a key stage in the broader history of agriculture, when early societies domesticated plants for food and trade. Today, a small number of staple crops such as rice, wheat, maize, and sugarcane account for the majority of global production.
ForagingForaging is searching for wild food resources. It affects an animal's fitness because it plays an important role in an animal's ability to survive and reproduce. Foraging theory is a branch of behavioral ecology that studies the foraging behavior of animals in response to the environment where the animal lives. Behavioral ecologists use economic models and categories to understand foraging; many of these models are a type of optimal model.
Afro-EurasiaAfro-Eurasia (also known as Afroeurasia, and Eurafrasia) is a landmass, occasionally described as a supercontinent, comprising the continents of Africa, Asia, and Europe. The terms are compound words of the names of its constituent parts. Afro-Eurasia has also been called the "Old World", in contrast to the "New World" referring to the Americas plus sometimes Oceania and Antarctica.
Geologic time scaleThe geologic time scale or geological time scale describes how geologic time is divided into standardised intervals. It uses the rock record together with the principles of chronostratigraphy to place rock sequences into their relative age positions, and geochronology techniques, such as radiometric dating, to precisely date the boundaries between them.*As an Amazon Associate I earn from qualifying purchases.
