Complete answer:
Peking man was formerly known as the Sinanthropus pekinensis. They belong to the homo erectus. They are considered to be the ancestors of the Chinese people. Their age is estimated to be 750,000 and 300,000 years old.

Additional information:
- Australopithecus is known to be a common ancestor of humans and apes. They were found in the southern African regions. They lived 4.4 million years ago. They were very human- like as they walked on the lower limbs and they had small brains which is a feature similar to the ape. Their teeth were similar to the ape and their cheeks were larger than the modern human indicating a larger jaw.
