The language is given to the
human being by God or a
divine divinity.
The Nature Sound Source
The first primitive words were made through
the imitations of the natural sounds that the
human being listened to around him.
Onomatopoeia
The Social Interaction
Source
Language develops in a social context.
The Physical
adaptation source
As the body is evolving,
language is also evolving /
changing at the same time.
The Tool-making
source
The tool-making involved the ability to take two, let's say rocks, and put them together to
create something. The same ability may have been used to put sounds together to create a
new tool - language.
The Genetic source
It is thought that a crucial mutation that took place over a short
period caused a genetic change that made it possible for
humans to create a language.
