Biological Scenarios For Language Evolution
Further information: Evolutionary linguisticsAll human populations possess language. This includes populations, such as the Tasmanians and the Andamanese, who may have been isolated from the Old World continents for as long as 40,000 years.
Linguistic monogenesis is the hypothesis that there was a single proto-language, sometimes called Proto-Human, from which all other vocal languages spoken by humans descend. (This does not apply to sign languages, which are known to arise independently rather frequently.)
The multiregional hypothesis would entail that modern language evolved independently on all the continents, a proposition considered implausible by proponents of monogenesis.

Famous quotes containing the words biological, scenarios, language and/or evolution:
“I am fifty-two years of age. I am a bishop in the Anglican Church, and a few people might be constrained to say that I was reasonably responsible. In the land of my birth I cannot vote, whereas a young person of eighteen can vote. And why? Because he or she possesses that wonderful biological attribute—a white skin.”
—Desmond Tutu (b. 1931)
“The taste for worst-case scenarios reflects the need to master fear of what is felt to be uncontrollable. It also expresses an imaginative complicity with disaster.”
—Susan Sontag (b. 1933)
“Repeat thy song, till the familiar lines
Are footpaths for the thought of Italy!
Thy flame is blown abroad from all the heights,
Through all the nations, and a sound is heard,
As of a mighty wind, and men devout,
Strangers of Rome, and the new proselytes,
In their own language hear thy wondrous word,
And many are amazed and many doubt.”
—Henry Wadsworth Longfellow (1809–1882)
“The more specific idea of evolution now reached is—a change from an indefinite, incoherent homogeneity to a definite, coherent heterogeneity, accompanying the dissipation of motion and integration of matter.”
—Herbert Spencer (1820–1903)
