The origin of language, its relationship with human evolution, and its consequences have been subjects of study for centuries.Scholars wishing to study the origins of language draw inferences from evidence such as the fossil record, archaeological evidence, contemporary language diversity, studies of language acquisition, and comparisons between human language and systems of animal ...
Note-taking has been an important part of human history and scientific development. The Ancient Greeks developed hypomnema, personal records on important subjects.In the Renaissance and early modern period, students learned to take notes in schools, academies and universities, often producing beautiful volumes that served as reference works after they finished their studies.
In Larry Niven's 1980 short story "The Green Marauder", [6] an alien over 700 million years old (due to relativistic travel) tells a human about the last time it visited Earth, and the hopeless plea from Earth's anaerobic civilization for help against the growing environmental threat of chlorophyll.
Hominini: The latest common ancestor of humans and chimpanzees is estimated to have lived between roughly 10 to 5 million years ago. Both chimpanzees and humans have a larynx that repositions during the first two years of life to a spot between the pharynx and the lungs, indicating that the common ancestors have this feature, a precondition for ...
Both dates consequently vary widely from region to region. For example, in European regions, prehistory cannot begin before c. 1.3 million years ago, which is when the first signs of human presence have been found; however, Africa and Asia contain sites dated as early as c. 2.5 and 1.8 million years ago, respectively.

[112] [113] In September 2019, scientists reported the computerized determination, based on 260 CT scans, of a virtual skull shape of the last common human ancestor to modern humans (H. sapiens), representative of the earliest modern humans, and suggested that modern humans arose between 260,000 and 350,000 years ago through a merging of ...
A researcher claims to have found evidence of humans in Chesapeake Bay over 22,000 years ago. The assertion is yet another recent announcement claiming to push the arrival of humans in North ...
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.
