As such, the terms become less applicable when their markers correlate less with cultural evolution. Therefore, the Neolithic and the Neolithic Revolution have little to do with the Americas , where several different chronologies are used instead depending on the area (e.g. the Andean Preceramic , the North American Archaic and Formative periods).
Beginning of animal evolution. [54] [55] 720–630 Ma Possible global glaciation [56] [57] which increased the atmospheric oxygen and decreased carbon dioxide, and was either caused by land plant evolution [58] or resulted in it. [59] Opinion is divided on whether it increased or decreased biodiversity or the rate of evolution. [60] [61] [62 ...
This is a list of dates associated with the prehistoric peopling of the world (first known presence of Homo sapiens). The list is divided into four categories, Middle Paleolithic (before 50,000 years ago), Upper Paleolithic (50,000 to 12,500 years ago), Holocene (12,500 to 500 years ago) and Modern ( Age of Sail and modern exploration).
Overview map of the peopling of the world by early humans during the Upper Paleolithic, following the Southern Dispersal paradigm. The so-called "recent dispersal" of modern humans took place about 70–50,000 years ago. [60] [61] [62] It is this migration wave that led to the lasting spread of modern humans throughout the world.
The purpose of prehistoric archaeology is to explore and understand civilisations that existed before writing systems; including the Stone, Bronze and Iron Age societies across the world. Within its early origins prehistoric archaeology had a focus on gathering artefacts and treasures to display in museums and private collections often to bring ...

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.
The period when a culture is written about by others, but has not developed its own writing system, is often known as the protohistory of the culture. By definition, [ 2 ] there are no written records from human prehistory, which can only be known from material archaeological and anthropological evidence: prehistoric materials and human remains.
