Final answer:
The Zhou dynasty is at a similar age to the Zhoukoudian site in the Chinese sequence, which represents a significant period of agricultural and technological advancements, along with territorial expansion of the Zhou settlements.
Step-by-step explanation:
The site that is at the similar age of Zhoukoudian in the Chinese sequence is likely associated with the Zhou dynasty, which coexisted with the Shang dynasty towards the end of its reign. This period was marked by numerous developments, including advances in agriculture, increased use of iron following the discovery in the local mountains, and the spread of Zhou settlements throughout the eastern plains. The Zhoukoudian site is noted for its archaeological significance, particularly with regards to the appearance of Homo erectus and can be paralleled historically with the Zhou dynasty era considering similar timing in the broad scope of Chinese prehistory and early historical record.
