Skull discovery sheds light on early humans

A skull dating back 1.8 million years has offered new insights in to the story of human evolution.

It has long been believed that several species of human originally emerged from Africa, but now a perfectly preserved skull and other remains unearthed in Georgia appear to suggest that our ancestors had actually emerged from the continent as a single species.

The skull was found along with the remains of four other individuals and several stone tools in a region believed to have been part of the route used during the earliest human migrations from Africa. At the time the area would have been covered in humid forests where dangerous creatures such as sabre-tooth tigers would have roamed.

By analyzing the skulls, scientists were able to determine that the variations in each individual were no greater than what would be expected in five individuals of any single primate species such as chimpanzees or modern humans.

"There are these jaw-dropping moments in the life of a scientist," said neurobiologist Christoph Zollikofer. "You can feel in your brain how all these preconceived ideas you had start falling to pieces."

I read this a couple days ago. What struck me is that even if the skulls of the various homonid species do fit within the current level of physical diversity, in the specific areas and timelines, the traits of specific "species" were consistant. The physical diversity appears, from what I've read, to have been low within these groups.

I would be careful with this article, it seems to be a tad bit sensationalized. All I got from it was H. erectus left Africa 200k years before originally thought and that their features varied as you would expect a populations features to.

Yeah, I'm a little skeptical about this as well. Not saying that it might not be true, just that I don't think there is enough evidence for conclusion.

As for rewriting textbooks, that should've happened like a hundred times in the past 20 years, only it NEVER happens. One of my colleagues is a history teacher, graduated from Cambridge, but she's never even heard of Gobekli Tepe, even though it's been being excavated for almost 20 years and dates back 10.000 years. Or Puma Punku for that matter. That's world class education. And you want these in textbooks? Gimme a break..

having read the article in detail, my conclusion is, they do one or two more similar discoveries and realize that a chimp one day pushed out a sapiens with an atom smasher crammed up his a*s

New textbooks come out all the time with all the latest confirmed knowledge. If it doesn't happen to have your particular slant, then maybe there is something wrong with your slant.
