Peking Man is a term used to describe a group of hominids who lived in China approximately 750,000 years ago. The term has been used for many years and has since been replaced by newer and more accurate terminology. There are several synonyms for the term "Peking Man," including Homo erectus pekinensis, Sinanthropus pekinensis, and Yuanmou Man. These terms are more specific and provide a clearer understanding of the characteristics of the hominids that lived during that time. Using updated nomenclature helps to clarify scientific research and create a more accurate understanding of early human history.
