The Paleolithic or Palaeolithic (c. 3.3 million – c. 11,700 years ago) (/ ˌ p eɪ l i oʊ ˈ l ɪ θ ɪ k, ˌ p æ l i-/ PAY-lee-oh-LITH-ik, PAL-ee-), also called the Old Stone Age (from Ancient Greek παλαιός (palaiós) 'old' and λίθος (líthos) 'stone'), is a period in human prehistory that is distinguished by the original development of stone tools, and which represents almost ...
North American archaeological periods divides the history of pre-Columbian North America into a number of named successive eras or periods, from the earliest-known human habitation through to the early Colonial period which followed the European colonization of the Americas.
The term Paleo-Indians applies specifically to the lithic period in the Western Hemisphere and is distinct from the term Paleolithic. [note 1] Traditional theories suggest that big-animal hunters crossed the Bering Strait from North Asia into the Americas over a land bridge . This bridge existed from 45,000 to 12,000 BCE (47,000–14,000 BP). [1]
Human history or world history is the record of humankind from prehistory to the present. Modern humans evolved in Africa around 300,000 years ago and initially lived as hunter-gatherers. They migrated out of Africa during the Last Ice Age and had spread across Earth's continental land except Antarctica by the end of the Ice Age 12,000 years ago.
The Lower Paleolithic (or Lower Palaeolithic) is the earliest subdivision of the Paleolithic or Old Stone Age.It spans the time from around 3.3 million years ago when the first evidence for stone tool production and use by hominins appears in the current archaeological record, [1] until around 300,000 years ago, spanning the Oldowan ("mode 1") and Acheulean ("mode 2") lithics industries.
Lower Paleolithic – earliest subdivision of the Paleolithic or Old Stone Age. It spans the time from around 2.5 million years ago when the first evidence of craft and use of stone tools by hominins appears in the current archaeological record , until around 300,000 years ago, spanning the Oldowan ("mode 1") and Acheulean ("mode 2") lithic ...
The Upper Paleolithic (or Upper Palaeolithic) is the third and last subdivision of the Paleolithic or Old Stone Age. Very broadly, it dates to between 50,000 and 12,000 years ago (the beginning of the Holocene), according to some theories coinciding with the appearance of behavioral modernity in early modern humans. It is followed by the ...
The Stone Age was a broad prehistoric period during which stone was widely used to make stone tools with an edge, a point, or a percussion surface. The period lasted for roughly 3.4 million years [1] and ended between 4000 BC and 2000 BC, with the advent of metalworking. [2] It therefore represents nearly 99.3% of human history.
