Answer:
Homo erectus appeared about two million years ago and, in several early migrations, it spread throughout Africa (where it is dubbed Homo ergaster) and Eurasia. It was likely the first human species to live in a hunter-gatherer society and to control fire.
The evolution of modern humans from our hominid ancestor is commonly considered as having involved four major steps: evolving terrestriality, bipedalism, a large brain (encephalization) and civilization.
The first stage occurred hundreds of thousands of years ago, when our hominid ancestors began to migrate out of Africa. The second stage was the evolution of Neanderthals, while the third stage brought about the Atapuerca humans, who finally evolved into our modern body shape.
Modern period is the longest period in human history. Prehistory is the period before written history and early human migration in the lower palelithic saw home which erectus spread across the 1.8 millions of years ago.
