<p>Australopithecus anamensis (Lucy) was somewhere between 4.1 to 3.9 million years old. Lucy is one of the oldest known hominids to have walked upright, and she was found in Kenya.
<p>This skull is supposed to be evidence for the "multi-regional" theory of human evolution. Homo erectus evolved in Africa and supposedly migrated outward into the world around 1.5 million years ago. But there are 2 competing theories on how exactly Homo sapiens evolved from Homo erectus.
<p>One theory, "The Replacement Theory", says that Homo sapiens evolved in Africa and migrated to other regions around 400,000-125,000 years ago, replacing the less efficient Homo erectus that had migrated.
<p>Another theory, "The Multi-Regional Theory", says that Homo sapiens evolved from Homo erectus, but seperately in many different regions around the world.
