What ate the Theories behind the domestication of animals in the neolithic age?

 V.Gordon Childe (1952)

Who suggested that environmental changes at the end of the pleistocene were the stimulus towards food production.

 Childe contended that around 10,000 years prior, the environment in pieces of West Asia became drier due to a toward the north shift of the mid year downpours.

This drying up (i.e., evaporating) prompted a concentration of individuals, plants, and creatures near water assets like waterways and oases.

This implemented closeness in the long run prompted new connections of reliance between

people, plants, and creatures, bringing about training.

 

Robert J. Braidwood (1960)

who rejected environmental change as a crucial factor contributing to agriculture. He highlighted that environmental changes also occurred in the Pleistocene and had not led to agriculture. Braidwood argued domestication was the root cause.

 

As a result of human experimentation as well as people becoming more familiar with their environment, domestication probably happened in such areas. However, this theory does not explain the pressures or incentives that may have led to domestication. There is ethnographic evidence of many hunting-related pressures.

Lewis R. Binford (1968)

he rejected Braidwood's theories, arguing that they could not be archaeologically tested, and there must be some specific, concrete factors that could explain the beginnings of agriculture.

Environmental change and demographic (population) growth can upset the balance between people and food. Binford identified two kinds of demographic stress - internal and external.In the context of the origins of agriculture, Binford stressed external demographic stress, which is the result of immigration into an area by people from another area.

Kent Flannery (1969) instead examined the process of food production itself, rather than attempting to identify a single event that led to the beginnings of food production.Negative-feedback food procurement systems involve the balanced exploitation and use of food resources within an area and discourage any change. Positive-feedback food procurement systems encourage the exploitation and use of resources.The genetic changes resulting from crossbreeding increased the productivity of this resource, and once people recognized this increased productivity, they increasingly domesticated maize. This explains why people found agriculture useful.

The key may indeed lie in environmental change, although not the type suggested many years ago by Childe. The decline of big game in Europe was not really a factor in zones of early agriculture such as West Asia.
