Archaeological studies suggest the theory
• Homo sapiens, the first modern humans, evolved from their early hominid predecessors between 200,000 and 300,000 years ago. They developed a capacity for language about 50,000 years ago. The first modern humans began moving outside of Africa starting about 70,000-100,000 years ago. Thus it cannot be said that human societies emerged at the same me in all the continents. Hence statement (a) is incorrect. • As per archaeological studies, hunting and gathering societies emerged before the farming societies. Hence statement (b) is incorrect. • The earliest human evolved in the Rift valley in East Africa. Hence statement (c) is correct. • The wheel was invented in the 4th millennium BC in Lower Mesopotamia (modern-day Iraq), where the Sumerian people inserted rotating axles into solid discs of wood. Hence statement (d) is incorrect.
