Ethiopia has often been called the original home of mankind because of various humanoid fossil discoveries like the Australopithecine Lucy. Northeastern Africa, and the Afar region in particular, was the central focus of these claims until recent DNA evidence suggested origins in south central Ethiopian regions like present-day Addis Ababa. After analysing the DNA of almost 1,000 people around the world, geneticists and other scientists claimed people spread from what is now Addis Ababa 100,000 years ago. The research indicated that genetic diversity decreases steadily the farther one's ancestors travelled from Addis Ababa, Ethiopia.
