These sites attest that early Homo erectus have crossed the North African tracts, which are usually hot and dry. [4]: 2 There is little time between Homo erectus' apparent arrival in South Caucasus around 1.8 Ma, and its probable arrival in East and Southeast Asia.
The researchers believe Homo erectus became isolated on the island around 1 million years ago and underwent a dramatic reduction in body size during a period of around 300,000 years.
Peking Man (Homo erectus pekinensis) is a subspecies of H. erectus which inhabited what is now northern China during the Middle Pleistocene.
