He had found them in prehistoric lake deposits along with the bones of extinct animals and concluded that they were made by people "who had not the use of metals" and that they belonged to a "very ancient period indeed, even beyond the present world".

His ideas were ignored by his contemporaries however, who held a pre-Darwinian view of human evolution.

They lived by gathering plants and hunting wild animals.

The earliest user of Acheulean tools was Homo ergaster who first appeared about 1.8 million years ago.

Some researchers prefer to call these users early Homo erectus.

Now it is realised that stone tools were used much earlier (3.3 million years ago) and that was definitely before the genus Homo had evolved.

It is not known for sure which species actually created and used Oldowan tools. Early Homo erectus appears to inherit Oldowan technology and refines it into the Acheulean industry beginning 1.7 million years ago.

They are first developed out of the more primitive Oldowan technology some 1.8 million years ago, by Homo habilis.

It was the dominant technology for most of human history.

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.

The geological period which corresponds to the Palaeolithic is the Pleistocene.

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.
