A 2012 paper studied the DNA sequence of around 6,500 Americans of European and African descent and confirmed earlier work indicating that the majority of changes to a single letter in the sequence (single nucleotide variants) were accumulated within the last 5,000-10,000 years. Almost three quarters arose in the last 5,000 years or so.
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.
Scientific papers have been categorised into ten types. Eight of these carry specific objectives, while the other two can vary depending on the style and the intended goal. [4] Papers that carry specific objectives are: [4] An original article provides new information from original research supported by evidence.
Happiness, or the state of being happy, is a human emotional condition. The definition of happiness is a common philosophical topic. Some define it as experiencing the feeling of positive emotional affects, while avoiding the negative ones. [328] [329] Others see it as an appraisal of life satisfaction or quality of life. [330]
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 ...
Fragment of the Histories by Herodotus, an Ancient Greek historical text, found in Egypt. The word history comes from the Ancient Greek term ἵστωρ (histōr), meaning ' learned, wise man '. It gave rise to the Ancient Greek word ἱστορία (historiā), which had a wide meaning associated with inquiry in general and giving testimony.
A further view, taken by archaeologists such as Francesco d'Errico [28] and João Zilhão, [34] is a multi-species perspective arguing that evidence for symbolic culture, in the form of utilised pigments and pierced shells, are also found in Neanderthal sites, independently of any "modern" human influence.
Human evolutionary genetics studies how one human genome differs from another human genome, the evolutionary past that gave rise to the human genome, and its current effects. Differences between genomes have anthropological , medical , historical and forensic implications and applications.
