Fossil Primate Ardipithecus Ramidus Described (Finally)

Omomyid writes "I wasn't actually aware that Dr. Tim White of UC Berkeley had been 'sitting' on A. ramidus but apparently he has (I remember the original flurry of interest back in the '90s when it was announced), but now Dr. White and others have assembled a nearly complete skeleton of the 4.4mya specimen and the descriptions being carried by the NY Times and the AP are intriguing. Ramidus is clearly differentiated from the other Great Apes and also more primitive than A. afarensis (Lucy), providing a nice linkage backwards to the last shared ancestor between humans and chimpanzees. According to the NY Times, a whole passel of papers will be published in tomorrow's Science magazine describing A. ramidus." Update — 10/01 at 22:05 GMT by SS: Reader John Hawks provided a link to his detailed blog post about Ardipithecus, which contains a ton of additional details not covered in the above articles.

why is it so interesting to study where humans have come from and why exactly monkeys? Yeah they maybe look the most of us from all the animals, but intelligently and in other ways they're totally different.
This is exactly what's mentioned in one of the articles: "Ardi has many traits that do not appear in modern-day African apes, leading to the conclusion that the apes evolved extensively since we shared that last common ancestor."
It makes sense, if we evolved from the common ancestor in six million years, it's only reasonable to assume monkeys and apes also evolved. Think of the common ancestor not as an ape, but something that's as different from modern apes as it's different from humans.
