View Full Version : Fossils plug gap in human origins

"Three partial skulls excavated in eastern Africa, dating to between 154,000 and 160,000 years ago, represent the oldest known fossils of modern people, according to the ancient skulls' discoverers. The new finds of Homo sapiens fossils, unearthed near an Ethiopian village called Herto, fill a major gap in the record of our direct ancestors. Modern H. sapiens fossils previously found in Africa and Israel date to about 100,000 years ago. A skull excavated in Ethiopia of a not-yet-modern, so-called archaic H. sapiens is roughly 500,000 years old. "

So how strong are the boundaries between modern man and archaic man anyway?

Are the scientists continuously widening up the limits of what can be called "modern man"?

It seems sometime in the last half a million years, a radical change occured, spawning modern man. Hmm.

There is a long series of relatively serious changes from early man to modern man. Length of jaw, teeth, facial area and brain pan size all change from archaic to modern man. In the spine and pelvis we see some serious changes also... the evolution from archaic to modern man sees a widening of the pelvis and some changes in the spine (and leg and feet bones) that help adapt modern man to fully bipedal stature.

This is so wild. It's amazing to me how much the science of archeology has grown just in the last 20 years. When I was in school, we were taught that Homo sapiens as a species is no more than 10,000 years old. They've already multiplied that estimate more than ten-fold.
