These tools are the first cultural products which have survived.
The Palaeolithic age began when hominids (early humans) started to use stones as tools for bashing, cutting and scraping.
They were made by all previous members of the genus, starting with relatively crude tools made by Homo habilis and Homo erectus.
In Europe, the large-brained Neanderthal Man (Homo neanderthalensis) made tools of high quality, and was in turn outshone by the many tools made by our own species.
Stone tools were not only made by our own species, Homo sapiens.
In individual regions, this dating can be considerably refined; in Europe for example, Acheulean methods did not reach the continent until around 400 thousand years ago and in smaller study areas, the date ranges can be much shorter.
Numerical dates can be misleading however, and it is common to associate examples of this early human tool industry with one or more glacial or interglacial periods or with a particular early species of human.
John Frere was the first to suggest in writing a very ancient date for Acheulean hand-axes.
In 1797 he sent two examples to the Royal Academy in London from Hoxne in Suffolk.
More than a million years ago Acheulean tool users left Africa to colonize Eurasia.
