Kung San who live similarly to their Paleolithic predecessors. Most known hominin fossils dating earlier than one million years before present are found in this area, particularly in KenyaTanzaniaand Ethiopia. Southern Caucasus was occupied by c. By the end of the Lower Paleolithic, members of the hominin family were living in what is now China, western Indonesia, and, in Europe, around the Mediterranean and as far north as England, southern Germany, and Bulgaria.
Ancient grains Map of the world showing approximate centers of origin of agriculture and its spread in prehistory: Gordon Childe to describe the first in a series of agricultural revolutions in Middle Eastern history. The period is described as a "revolution" to denote its importance, and the great significance and degree of change affecting the communities in which new agricultural practices were gradually adopted and refined.
Recent archaeological research suggests that in some regions such as the Southeast Asian peninsula, the transition from hunter-gatherer to agriculturalist was not linear, but region-specific.
The most prominent of these are: However, today this theory has little support amongst archaeologists because subsequent climate data suggests that the region was getting wetter rather than drier.
This required assembling large quantities of food, which drove agricultural technology. The Demographic theories proposed by Carl Sauer  and adapted by Lewis Binford  and Kent Flannery posit an increasingly sedentary population that expanded up to the carrying capacity of the local environment and required more food than could be gathered.
Various social and economic factors helped drive the need for food. Starting with domestication by protection of wild plants, it led to specialization of location and then full-fledged domestication.
Peter RichersonRobert Boydand Robert Bettinger  make a case for the development of agriculture coinciding with an increasingly stable climate at the beginning of the Holocene. The postulated Younger Dryas impact eventclaimed to be in part responsible for megafauna extinction and ending the last glacial periodcould have provided circumstances that required the evolution of agricultural societies for humanity to survive.
Leonid Grinin argues that whatever plants were cultivated, the independent invention of agriculture always took place in special natural environments e. It is supposed that the cultivation of cereals started somewhere in the Near East: So Grinin dates the beginning of the agricultural revolution within the interval 12, to 9, BP, though in some cases the first cultivated plants or domesticated animals' bones are even of a more ancient age of 14—15 thousand years ago.
In "A Reassessment of the Neolithic Revolution", Frank Hole further expanded the relationship between plant and animal domestication. He suggested the events could have occurred independently over different periods of time, in as yet unexplored locations.
He noted that no transition site had been found documenting the shift from what he termed immediate and delayed return social systems. He noted that the full range of domesticated animals goatssheepcattle and pigs were not found until the sixth millennium at Tell Ramad.
Hole concluded that "close attention should be paid in future investigations to the western margins of the Euphrates basin, perhaps as far south as the Arabian Peninsulaespecially where wadis carrying Pleistocene rainfall runoff flowed.
Plants with traits such as small seeds or bitter taste would have been seen as undesirable. Plants that rapidly shed their seeds on maturity tended not to be gathered at harvest, therefore not stored and not seeded the following season; years of harvesting selected for strains that retained their edible seeds longer.
Several plant species, the "pioneer crops" or Neolithic founder cropswere identified by Daniel Zoharywho highlighted the importance of the three cerealsand suggested that domestication of flaxpeaschickpeasbitter vetch and lentils came a little later. Based on analysis of the genes of domesticated plants, he preferred theories of a single, or at most a very small number of domestication events for each taxon that spread in an arc from the Levantine corridor around the Fertile Crescent and later into Europe.

Selectively propagated figswild barley and wild oats were cultivated at the early Neolithic site of Gilgal Iwhere in  archaeologists found caches of seeds of each in quantities too large to be accounted for even by intensive gatheringat strata datable to c.
Some of the plants tried and then abandoned during the Neolithic period in the Ancient Near East, at sites like Gilgal, were later successfully domesticated in other parts of the world. Once early farmers perfected their agricultural techniques like irrigation, their crops would yield surpluses that needed storage.
Most hunter gatherers could not easily store food for long due to their migratory lifestyle, whereas those with a sedentary dwelling could store their surplus grain.
Eventually granaries were developed that allowed villages to store their seeds longer.
So with more food, the population expanded and communities developed specialized workers and more advanced tools. The process was not as linear as was once thought, but a more complicated effort, which was undertaken by different human populations in different regions in many different ways.The main differences between the Paleolithic and the Neolithic periods; Scope of time - The Palaeolithic covers an immense time span; around million years ago - around 12, years ago.
The Neolithic Revolution The anthropologists found evidence in which the scholar divided the prehistory in two ares, the first one was called the old Stone age or the Paleolithic perio and the Neolithic period in which people made important advances in technology.
The Paleolithic Age is considered the “Old Stone Age” while the Neolithic Age is the “New Stone Age.” During the Paleolithic era, humans had more of a nomadic lifestyle and tended to move with the herds. Dating to approximately B.C.E. and set on Salisbury Plain in England, it is a structure larger and more complex than anything built before it in Europe.
The Neolithic Revolution, also called the Agricultural Revolution, marked the transition in human history from small nomadic bands of hunter-gatherers to larger, agricultural settlements and early. The Neolithic revolution took place in several stages. First, people settled down in permanent communities (“sedentism”), and afterwards they developed food production. Paleolithic – before 10, BCE – nomadic hunter-gathers of the Pleistocene (Ice Age). paleolithic - neolithic eras Together these developments are called the Neolithic Revolution and they allowed the development of urban centers (towns and, later, cities), trade and most of the other things we consider to be components of "civilization.".
Stonehenge is an example of the cultural advances brought about by the Neolithic revolution—the most important development in human history. The Paleolithic Period was also called the Old Stone Age. Neolithic is the later part of the Stone Age, when ground or polished stone weapons and implements prevailed.
The Neolithic Period was also called the New Stone Age. The Neolithic Revolution was the world’s first traditionally, provable revolution in . This region kick-started the Neolithic Revolution. Dates for the domestication of these animals range from between 13, to 10, years ago.
Genetic studies show that goats and other livestock accompanied the westward spread of agriculture into Europe, helping to revolutionize Stone Age society.
