The categorisation of the past into discrete, quantified named blocks of time is called periodization. [1] This is a list of such named time periods as defined in various fields of study. These can be divided broadly into prehistorical periods and historical periods (when written records began to be kept).
Human 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.
Estimates for yet deeper prehistory, into the Paleolithic, are of a different nature. At this time, human populations consisted entirely of non-sedentary hunter-gatherer populations, with anatomically modern humans existing alongside archaic human varieties, some of which are still ancestral to the modern human population due to interbreeding ...

[1]A civilization (also spelled civilisation in British English) is any complex society characterized by the development of the state, social stratification, urbanization, and symbolic systems of communication beyond signed or ...
Tools found in the Dhofar Governorate correspond with African objects from the so-called 'Nubian Complex', dating from 75 to 125,000 years ago. According to archaeologist Jeffrey I. Rose, human settlements spread east from Africa across the Arabian Peninsula. [16] Africa, Central Africa: Democratic Republic of the Congo: 90: Katanda, Upper ...
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.
Scientific polygenism is a set of hypotheses resulting from the use of the scientific method to attempt explanation of the differences in traits between humans who live in different regions. Over the course of many centuries, polygenistic hypotheses have been dismissed by more accurate scientific theories.
