Why do early humans switched from hunting and gatheringto agriculture?

Lions and wolves communicate well enough to hunt as a group. Bees can tell each other where the best pollen is.
For almost the whole of human history, from at least 3 million years ago, mankind has lived by carrying out these two basic acitivities of hunting (or fishing) and gathering edible items of any kind (from fruit to insects). We are unusual among animals in combining the two functions, and we have been greatly helped in both by the development of language. But basically, as hunter-gatherers, we have lived by doing what comes naturally.
It is true that human beings have dignified both activities with elaborate ritual and with much attention to the spirits of nature. And it is true that in human societies the business of hunting and gathering has involved specialization, with men doing the hunting and women much of the gathering. And humans, unlike most animals, carry the food home and share it, rather than consume it there and then.
But all this is a result of our ability to communicate, to speculate, to rationalize. It does not alter the fact that for 3 million years Stone Age man, the hunter-gatherer, engages in an activity as natural as the swoop of a hawk or the grazing of a horse.
The Neolithic Revolution: 10,000 years ago
The change comes a mere 10,000 years ago, when people first discover how to cultivate crops and to domesticate animals. This is the most significant single development in human history. It happens within the Stone Age, for tools are still flint rather than metal, but it is the dividing line which separates the old Stone Age (palaeolithic) from the new Stone Age (neolithic). It has been aptly called the Neolithic Revolution.
The strange thing is that this revolution occurs independently in separate parts of the world - the Middle East, for example, and America. How can this unlikely coincidence occur?
Part of the reason may be the ending of the most recent cold phase of the present ice age (see Ice Ages). This creates new temperate regions, in which humans can live comfortably. By contrast many of their main victims in the chase cannot survive in the changed climate.
Herds of bison move to colder regions. Mammoths become extinct. But plants of all kinds grow more easily in the new temperate zones.
It is not hard to imagine, in these circumstances, a strong human impulse to abandon the pursuit of the bison and to stay, instead, in a region where edible plants are now growing in sufficient profusion to seem worth encouraging and protecting (by weeding around them, for example). Some human groups adapt to a new way of life. Others go after the bison.
If the impulse is to settle, there is also a strong incentive to ensure that animals remain nearby as a supply of food. This may involve attempts to herd them, to pen them in enclosures, or to entice them near the settlement by laying out fodder.
The first farmers: from 8000 BC
From weeding around a plant, or perhaps watering it in a dry spell, it is a small step to collecting its seeds and planting them in a protected spot where they will have a better than average chance of growing. From penning in animals, to kill them when needed, it is a small step to keeping them until their offspring are born.
In any one place the process will be gradual. Cultivated crops or domesticated animals form at first only a small part of a community's diet, most of it coming still from hunting and gathering. In each place where the change happens, its pattern is no doubt different. But in the Middle East, in America, in China and southeast Asia, the change does occur.
