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).
Prehistoric demography, palaeodemography or archaeological demography is the study of human and hominid demography in prehistory. [ 1 ] More specifically, palaeodemography looks at the changes in pre-modern populations in order to determine something about the influences on the lifespan and health of earlier peoples.
From the 1970s onward, the dominant scientific perspective of gendered roles in hunter-gatherer societies was of a model termed "Man the Hunter, Woman the Gatherer".Coined by anthropologists Richard Borshay Lee and Irven DeVore in 1968, it argued, based on evidence now thought to be incomplete, that contemporary foragers displayed a clear division of labor between women and men.

This timeline of prehistory covers the time from the appearance of Homo sapiens approximately 315,000 years ago in Africa to the invention of writing, over 5,000 years ago, with the earliest records going back to 3,200 BC. Prehistory covers the time from the Paleolithic (Old Stone Age) to the beginning of ancient history.
The difference in life expectancy between men and women in the United States dropped from 7.8 years in 1979 to 5.3 years in 2005, with women expected to live to age 80.1 in 2005. [87] Data from the United Kingdom shows the gap in life expectancy between men and women decreasing in later life.

While the human life span has increased markedly since the 19th century, new research shows that despite recent advancements in medicine, we may have reached our longevity peak—and most of today ...
The word "prehistory" first appeared in English in 1836 in the Foreign Quarterly Review. [16] The geologic time scale for pre-human time periods, and the three-age system for human prehistory, were systematised during the nineteenth century in the work of British, French, German, and Scandinavian anthropologists, archaeologists, and antiquarians.
