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 ...
Paleoanthropology or paleo-anthropology is a branch of paleontology and anthropology which seeks to understand the early development of anatomically modern humans, a process known as hominization, through the reconstruction of evolutionary kinship lines within the family Hominidae, working from biological evidence (such as petrified skeletal remains, bone fragments, footprints) and cultural ...
The Lower Paleolithic period was the 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 hominids appears in the current archaeological record , until around 300,000 years ago, spanning the Oldowan ("mode 1") and Acheulean ("mode ...

The Initial Upper Paleolithic corresponds to the spread of a particular techno-complex in Eurasia, [6] to which possibly relates the European Châtelperronian. [17] But the Aurignacian complex (Protoaurignacian and Early Aurignacian) with its famous Cave art seems to correspond to another, later, human wave which spread through the Levant area. [6]
The evolution of eukaryotes, and possibly sex, is thought to be related to the GOE, as it probably pressured two or three lineages of prokaryotes (including an aerobe one, which later became mitochondria) to depend on each other, leading to endosymbiosis. Early eukaryotes lost their cell walls and outer membranes.
The evolution of human intelligence is closely tied to the evolution of the human brain and to the origin of language. The timeline of human evolution spans approximately seven million years, [ 1 ] from the separation of the genus Pan until the emergence of behavioral modernity by 50,000 years ago.
Expansion of early modern humans from Africa. 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.
