Question

Scientists suspect that human language evolved around _______ years ago.

Answer 1

Scientists suspect that human language evolved around 150000 years ago.
the human language is linked to the Homo Sapiens who lived around 150,000 to 200,000 years ago in eastern or perhaps southern Africa
The reason why scientists suspect this is by evidence of abstract and symbolic behaviour in the early modern humans, taking the form of engravings on red-ochre.
