Stone Age

The Stone Age is a broad prehistoric period during which humans widely used stone for toolmaking. Stone tools were made from a variety of different sorts of stone. For example, flint and chert were shaped (or chipped) for use as cutting tools and weapons, while basalt and sandstone were used for ground stone tools, such as quern-stones. Wood, bone, shell, antler (deer) and other materials were widely used, as well. During the most recent part of the period, sediments (like clay) were used to make pottery. A series of metal technology innovations characterize the later Chalcolithic (Copper Age), Bronze Age and Iron Age.
The period from 2.9 million years ago  encompasses the first use of stone tools in Gona, Ethiopia and its spread and widespread use elsewhere soon thereafter. It ends with the development of agriculture, the domestication of certain animals, and the smelting of copper ore to produce metal. It is termed prehistoric since humanity had not yet started writing—the traditional start of history

Mesolithic age

The Mesolithic (Greek: mesos "middle", lithos stone) or "Middle Stone Age" was a period in the development of human technology in between the Paleolithic or Old Stone Age and the Neolithic or New Stone Age, in which farming appeared. The term was introduced by John Lubbock in his work Pre-historic Times, published in 1865. The term was, however, not much used until V. Gordon Childe popularized it in his book The Dawn of Europe (1947). The start and end dates of the Mesolithic vary by geographical region. In some areas, such as the Near East, farming was already in use by the end of the Pleistocene.

Neolithic age

The Neolithic Age, Era, or Period, or New Stone Age, was a period in the development of human technology, beginning about 9500 BC in the Middle East that is traditionally considered the last part of the Stone Age. The Neolithic followed the terminal Holocene Epipalaeolithic period, beginning with the rise of farming, which produced the "Neolithic Revolution" and ending when metal tools became widespread in the Copper Age (chalcolithic) or Bronze Age or developing directly into the Iron Age, depending on geographical region. The Neolithic is not a specific chronological period, but rather a suite of behavioral and cultural characteristics, including the use of wild and domestic crops and the use of domesticated animals. New findings put the beginning of the Neolithic culture back to around 10700 to 9400 BC in Tell Qaramel in northern Syria, 25 km north of Aleppo. Until those findings are adopted within the archaeological community, the beginning of the Neolithic culture is considered to be in the Levant (Jericho, modern-day West Bank) about 9500 BC. It developed directly from the Epipaleolithic Natufian culture in the region, whose people pioneered the use of wild cereals, which then evolved into true farming. The Natufians can thus be called "proto-Neolithic" (12,500–9500 BC or 12,000-9500 BC). As the Natufians had become dependent on wild cereals in their diet, and a sedentary way of life had begun among them, the climatic changes associated with the Younger Dryas are thought to have forced people to develop farming. By 9500–9000 BC, farming communities arose in the Levant and spread to Asia Minor, North Africa and North Mesopotamia. Early Neolithic farming was limited to a narrow range of plants, both wild and domesticated, which included einkorn wheat, millet and spelt, and the keeping of dogs, sheep and goats. By about 8000 BC, it included domesticated cattle and pigs, the establishment of permanently or seasonally inhabited settlements, and the use of pottery.

Civilization

Civilization  refers to either: 1) the procession of human societies generally toward more development and use of more complex technology, higher population densities, increasing per capita gross domestic product, and other significant advancements; or 2) any human society (for example, "Ancient Greek Civilization") associated with any particular geographical location at a particular time, historical or current. (When used in this second sense, the word is often restricted to apply only to societies that have attained a particular level of advancement, especially the founding of cities, with the word "city" defined in various ways.) The level of advancement of a civilization is often measured by its progress in agriculture, long-distance trade, occupational specialization, and urbanism. Aside from these core elements, civilization is often marked by any combination of a number of secondary elements, including a developed transportation system, writing, standards of measurement (currency, etc.), contract and tort-based legal systems, characteristic art styles (which may pertain to specific cultures), monumental architecture, mathematics, sophisticated metallurgy, and astronomy.
