Prehistory means history of a time before any written record. In such cases, it is very difficult to tell anything definite about the prehistory of China or any other country. Even then, historians believe some facts about the China of that period. About a million years ago Homo erectus, an early human species, lived in China. Later, about 65,000 years ago, modern human beings Homo sapiens reached China from Africa. For food, they hunted wild animals. They also began to pick and gather fruits, eventually resulting in the Chinese learning to farm by 5000 BC. They had started cultivating rice and possibly other types of grains. By 2500 BC, the Bronze Age had come to China. A ruling class with kings and queens had come into society.
