1.	Wright a not on early societies
Answer» The first is about the beginnings of human existence, from the remote past, millions of years ago. You will learn how humans first emerged in Africa and how archaeologists have studied these\xa0early\xa0phases of history from remains of bones and stone tools.\xa0Sumer, located in Mesopotamia, is the first known complex civilization, developing the first city-states in the 4th millennium BCE. It was in these cities that the earliest known form of\xa0writing, cuneiform script, appeared around 3000 BCE.\xa0The first six civilizations–Mesopotamia,\xa0Egypt,\xa0Indus Valley\xa0(Harappa), Andes, China, and Mesoamerica– are supposed to have arisen independently of each other approximately 6,000 to 3,500 years ago.
