Experts who study prehistoric life and the development of language think that language developed gradually, beginning as an imitation of sounds in nature, such as the barking of certain animals and the howling of the wind.
The first steps towards written language were paintings and drawings, also known as paleolithic art. Prehistoric artists began to use a series of pictures to tell a story, such as the story of a good hunting trip or a violent storm.
Gradually, people developed a system of small pictures that stood for most common objects and ideas. Such a system is known as pictographic writing.
