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 timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.
Ancient history – Aggregate of past events from the beginning of recorded human history and extending as far as the Early Middle Ages or the Postclassical Era. The span of recorded history is roughly five thousand years, beginning with the earliest linguistic records in the third millennium BC in Mesopotamia and Egypt .
"A sharp rock", an Oldowan pebble tool, the most basic of human stone tools The harnessing of fire was a pivotal milestone in human history. Acheulean hand-axes from Kent. H. erectus flint work. The types shown are (clockwise from top) cordate, ficron and ovate. Venus of Willendorf, an example of Paleolithic art, dated 24–26,000 years ago
It took over two million years of human prehistory and history for the human population to reach one billion and only 207 years more to grow to 7 billion. [147] The combined biomass of the carbon of all the humans on Earth in 2018 was estimated at 60 million tons, about 10 times larger than that of all non-domesticated mammals. [139]
Reconstruction of early Homo sapiens from Jebel Irhoud, Morocco c. 315 000 years BP. Early modern human (EMH), or anatomically modern human (AMH), [1] are terms used to distinguish Homo sapiens (sometimes Homo sapiens sapiens) that are anatomically consistent with the range of phenotypes seen in contemporary humans, from extinct archaic human species (of which some are at times also identified ...
Cave paintings (such as this one from France) represent a benchmark in the evolutionary history of human cognition. Victorian naturalist Charles Darwin was the first to propose the out-of-Africa hypothesis for the peopling of the world, [39] but the story of prehistoric human migration is now understood to be much more complex thanks to twenty-first-century advances in genomic sequencing.
History (derived from Ancient Greek ἱστορία (historía) 'inquiry; knowledge acquired by investigation') [1] is the systematic study and documentation of the human past. [2] [3] History is an academic discipline which uses a narrative to describe, examine, question, and analyse past events, and investigate their patterns of cause and effect.
