Life timeline and Nature timeline Modern Awash RiverEthiopia, descendant of the Palaeo-Awash, source of the sediments in which the oldest Stone Age tools have been found The Stone Age is contemporaneous with the evolution of the genus Homothe only exception possibly being the early Stone Age, when species prior to Homo may have manufactured tools.

The closest relative among the other living primatesthe genus Panrepresents a branch that continued on in the deep forest, where the primates evolved. The rift served as a conduit for movement into southern Africa and also north down the Nile into North Africa and through the continuation of the rift in the Levant to the vast grasslands of Asia.

All the tools come from the Busidama Formation, which lies above a disconformityor missing layer, which would have been from 2. The oldest sites containing tools are dated to 2.

Excavators at the locality point out that: The possible reasons behind this seeming abrupt transition from the absence of stone tools to the presence thereof include Fragments of Australopithecus garhiAustralopithecus aethiopicus [9] and Homo, possibly Homo habilishave been found in sites near the age of the Gona tools.

The first most significant metal manufactured was bronzean alloy of copper and tineach of which was smelted separately. The transition from the Stone Age to the Bronze Age was a period during which modern people could smelt copper, but did not yet manufacture bronze, a time known as the Copper Ageor more technically the Chalcolithic"copper-stone" age.

The Chalcolithic by convention is the initial period of the Bronze Age. The Bronze Age was followed by the Iron Age. The Americas notably did not develop a widespread behavior of smelting Bronze or Iron after the Stone Age period, although the technology existed.

In Europe and North America, millstones were in use until well into the 20th century, and still are in many parts of the world.

Concept of the Stone Age The terms "Stone Age", "Bronze Age", and "Iron Age" were never meant to suggest that advancement and time periods in prehistory are only measured by the type of tool material, rather than, for example, social organizationfood sources exploited, adaptation to climate, adoption of agriculture, cooking, settlement and religion.

Like potterythe typology of the stone tools combined with the relative sequence of the types in various regions provide a chronological framework for the evolution of man and society.

They serve as diagnostics of date, rather than characterizing the people or the society. Lithic analysis is a major and specialised form of archaeological investigation. It involves the measurement of the stone tools to determine their typology, function and the technology involved.

It includes scientific study of the lithic reduction of the raw materials, examining how the artifacts were made. Much of this study takes place in the laboratory in the presence of various specialists. In experimental archaeologyresearchers attempt to create replica tools, to understand how they were made.

Flintknappers are craftsmen who use sharp tools to reduce flintstone to flint tool. A variety of stone tools In addition to lithic analysis, the field prehistorian utilizes a wide range of techniques derived from multiple fields.

The work of the archaeologist in determining the paleocontext and relative sequence of the layers is supplemented by the efforts of the geologic specialist in identifying layers of rock over geologic time, of the paleontological specialist in identifying bones and animals, of the palynologist in discovering and identifying plant species, of the physicist and chemist in laboratories determining dates by the carbonpotassium-argon and other methods.

Study of the Stone Age has never been mainly about stone tools and archaeology, which are only one form of evidence.

The first stone

The chief focus has always been on the society and the physical people who belonged to it. Useful as it has been, the concept of the Stone Age has its limitations.

The date range of this period is ambiguous, disputed, and variable according to the region in question. The term was innovated to describe the archaeological cultures of Europe.

It may not always be the best in relation to regions such as some parts of the Indies and Oceania, where farmers or hunter-gatherers used stone for tools until European colonisation began.

The archaeologists of the late 19th and early 20th centuries CE, who adapted the three-age system to their ideas, hoped to combine cultural anthropology and archaeology in such a way that a specific contemporaneous tribe can be used to illustrate the way of life and beliefs of the people exercising a specific Stone-Age technology.
