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 ...
The highly diverse Nilo-Saharan languages, first proposed as a family by Joseph Greenberg in 1963 might have originated in the Upper Paleolithic. [1] Given the presence of a tripartite number system in modern Nilo-Saharan languages, linguist N.A. Blench inferred a noun classifier in the proto-language, distributed based on water courses in the Sahara during the "wet period" of the Neolithic ...
A development as complex as the reconfiguration of the human vocal tract would have required much more time, implying an early date of origin. This discrepancy in timescales undermines the idea that human vocal flexibility was initially driven by selection pressures for speech.
The ability to share and compare results from many regions and enlist more people into the production of science soon led to the development of early modern science. [138] Books of medicine began to incorporate observations from contemporary surgery and dissections, including printed plates providing illustrations, to improve knowledge of ...
The great apes (Hominidae) show some cognitive and empathic abilities. Chimpanzees can make tools and use them to acquire foods and for social displays; they have mildly complex hunting strategies requiring cooperation, influence and rank; they are status conscious, manipulative and capable of deception; they can learn to use symbols and understand aspects of human language including some ...
Language development in humans is a process which starts early in life. Infants start without knowing a language, yet by 10 months, ...
In 2011, an article in the journal Science proposed an African origin of modern human languages. [10] It was suggested that human language predates the out-of-Africa migrations of 50,000 to 70,000 years ago and that language might have been the essential cultural and cognitive innovation that facilitated human colonization of the globe.

H. erectus is the first known species to develop control of fire, by about 1.5 Ma. H. erectus later migrates throughout Eurasia, reaching Southeast Asia by 0.7 Ma. It is described in a number of subspecies. [38] Early humans were social and initially scavenged, before becoming active hunters.
