Most anthropologists today hold with the theory that modern humans evolved in Africa. This theory has come to be known as the Out-of-Africa model and was first proposed by Chris Stringer and Peter Andrews. In this model, humans evolved from more primitive hominids into more or less the modern humans we are now and began migrating out of Africa around 200,000 years ago. Archaeological excavations in Africa have uncovered many examples of early human remains that are older than any found elsewhere in the world. The most famous of these findings is the fossil known as "Lucy," a female who lived in the region that is now Ethiopia. Donald Johanson, who discovered Lucy, says this about the Out-of-Africa theory:
"The one thing that all anthropologists have agreed on now is that the fossil record for humanity is so convincing, from the very earliest, very primitive stages, long before Lucy, going back as much as six million years in Africa, that this is really the cradle of humankind, Africa."
