Homo erectus lived in Northern, Eastern, and Southern Africa; Westerner Asia (Dmanisi, Republic of Georgia); East Asia (China and Indonesia). They lived between about 1.89 million and 110,000 years ago. Homo erectus is considered to possibly be the longest lived early human species-about nine times as long as our own species, Homo sapiens, has been around. On the other hand, Homo sapiens came into the picture some 300,000 years ago and we are still here now. Homo sapiens evolved in Africa and are now worldwide.
