the key invention of the neolithic era was the development of
Neolithic Traditionally considered the last part of the Stone Age or The New Stone Age, the Neolithic followed the terminal Holocene Epipaleolithic period and commenced with the beginning of farming, which produced the "Neolithic Revolution". It ended when metal tools became widespread (in the Copper Age or Bronze Age; or, in some geographical regions, in the Iron Age). The Neolithic is a progression of behavioral and cultural characteristics and changes, including the use of wild and domestic crops and of domesticated animals.[a]
Acheulean Acheulean (/əˈʃuːliən/; also Acheulian and Mode II), from the French acheuléen, is an archaeological industry of stone tool manufacture characterized by distinctive oval and pear-shaped "hand-axes" associated with early humans. Acheulean tools were produced during the Lower Palaeolithic era across Africa and much of West Asia, South Asia, and Europe, and are typically found with Homo erectus remains. It is thought that Acheulean technologies first developed in Africa out of the more primitive Oldowan technology as long as 1.76 million years ago, by Homo habilis. Acheulean tools were the dominant technology for the vast majority of human history.[3][4][5]
