===Concept of the Stone Age===
The terms "Stone Age", "Bronze Age", and "Iron Age" are not intended to suggest that advancements and time periods in prehistory are only measured by the type of tool material, rather than, for example, [[social organization]], [[food sources]] exploited, adaptation to climate, adoption of agriculture, cooking, [[Human settlement|settlement]], and religion. Like [[pottery]], the typology of the stone tools combined with the relative sequence of the types in various regions provide a chronological framework for the evolution of humanity 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 [[stone tool]]s to determine their typology, function and technologies involved. It includes the scientific study of the [[lithic reduction]] of the raw materials and methods used to make the prehistoric artifacts that are discovered. Much of this study takes place in the laboratory in the presence of various specialists. In [[experimental archaeology]], researchers attempt to create replica tools, to understand how they were made. [[Flintknapper]]s are craftsmen who use sharp tools to reduce [[flint]]stone to [[Flint (tool)|flint tool]].

In addition to lithic analysis, field prehistorians use a wide range of techniques derived from multiple fields. The work of archaeologists in determining the paleocontext and relative sequence of the layers is supplemented by the efforts of geologic specialists in identifying layers of rock developed or deposited over geologic time; of paleontological specialists in identifying bones and animals; of palynologists in discovering and identifying pollen, spores and plant species; of physicists and chemists in laboratories determining ages of materials by [[carbon-14]], [[K–Ar dating|potassium-argon]] and other methods. The study of the Stone Age has never been limited to stone tools and archaeology, even though they are important forms of evidence. The chief focus of study has always been on the society and the living 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, depending upon the region in question. While it is possible to speak of a general 'Stone Age' period for the whole of humanity, some groups never developed metal-[[smelting]] technology, and so remained in the so-called 'Stone Age' until they encountered technologically developed cultures. The term was innovated to describe the [[archaeological culture]]s 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-gatherer]]s used stone for tools until European [[colonisation]] began.

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 could be used to illustrate the way of life and beliefs of the people exercising a particular Stone-Age technology. As a description of people living today, the term ''Stone Age'' is controversial. The [[Association of Social Anthropologists]] discourages this use, asserting:<ref>{{cite news | title=ASA Statement on the use of 'primitive' as a descriptor of contemporary human groups | newspaper=ASA News | date=27 August 2007 | publisher=Association of Social Anthropologists of the UK and Commonwealth | url=http://www.theasa.org/news.shtml#asa | access-date=31 October 2011 | archive-url=https://web.archive.org/web/20111114155909/http://www.theasa.org/news.shtml#asa | archive-date=14 November 2011 | url-status=dead | df=dmy-all }}</ref><blockquote>To describe any living group as 'primitive' or 'Stone Age' inevitably implies that they are living representatives of some earlier stage of human development that the majority of humankind has left behind.</blockquote>
