Nanjing Man cranium, front view. The Nanjing man (Homo erectus), was discovered in Tangshan cave near Nanjing in 1993 and is thought to be between 580,000 and 620,000 years old. It provides important clues to human evolution and has even cast doubt on the Out-of-Africa model, which states that Homo sapiens have a single origin in Africa and arrived in China about 100,000 to 200,000 years ago. This specimen was old enough to suggest that a human population in Asia could have had enough time to evolve in its own right.
