This article reports on recent archaeological findings that raise interesting questions about accepted theories of human evolution and, in particular, about when human ancestors first moved out of Africa. Paleontologists have discovery ancient human remains — dating back some 1.8 million years — in modern Georgia, near the Caucuses. The remains are significantly smaller in physical size, and brain size, than previously identified Homo Erectus remains, and are by far the oldest proto-human remains found out of Africa.
Previously, the prevailing view was that human ancestors first journeyed out of Africa 1 million years ago and began to colonize the world. This discovery suggests that the human diaspora began much earlier — and may even indicate that there are significant issues about where certain human species actually originated. The story of human evolution is a fascinating one, and much remains to be discovered and written.
