The Appearance of humans

Fossils along with evidence of fire and other activities indicate that humans appeared during late Pliocene (8-10 million years ago) in Africa , a region of relatively warm climate , and by the late Pleistocene (about 500,000 years ago) humans migrated northward from Africa into Europe and eastward into Asia.

Paint engineering in prehistoric times (cave painting)

Many cave paintings of prehistoric times were discovered in Europe , Africa and Asia.
The cave drawing and paintings were done by people who lived by hunting animals and gathering wild plants that were suitable to be eaten.
