People often talk about homosapien evolving from chimpanzees but really it is that we share a common ancestor. I just wondered whether there was a name for this common ancestor species and if there isn't perhaps there really aught to be.

I suggest a quick google search on human evolution. We aren't descended from chimps. We diverged from a common ancestor.
Or did you really mean "chips"? We and chips evolved from er ... ahhh... Fish and Chip shops.

Some Googling indicates that the timeline is still in debate, but may be in the 5-7 MYA range. I think they'll need to nail down the time more closely before they can name a species.

Hmm, I always thought that was called the "Missing Link." Or has that link been found?

um... its my understanding that "chips" evolved from silicon...

They found it, but it just made two more missing links, one on either side.Hmm, I always thought that was called the "Missing Link." Or has that link been found?

Sorry Frog march I thought you wrote that we evolved from chimps. Sorry I cant give you a name.
Seems the latest studies are saying we are so close that proto humans and proto chimps interbred.
http://www.sciencenews.org/articles/20060520/fob4.aspClues to ancient interbreeding lie on the X chromosome, Reich and his coworkers say. People and chimps exhibit far more similarity on that sex-linked DNA strand than on any of the other 22 chromosomes. Genetic detachment of human ancestors, or hominids, from chimps seems to have occurred on the X chromosome about 1.2 million years later than it did on other chromosomes, the scientists report.
A partial genetic cleavage of hominids and chimp ancestors, followed by interbreeding that reshaped the sex chromosomes, then a conclusive split, best explains these findings, in the researchers' view. If they're right, then presumed hominid fossils from more than 6 million years ago (SN: 7/13/02, p. 19: http://www.sciencenews.org/articles/20020713/fob1.asp) would have preceded the final split and actually come from hybrid creatures.

Yep. I haven't seen identified the species from which both chimpanzees and humans evolved.
Wikipedia: Hominini:
Genera within tribe Hominini include:Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Primates
Superfamily: Hominoidea
Family: Hominidae
Subfamily: Homininae
Tribe: Hominini
I suspect it might be a miracle to discover the actual species from which we both arose. It might even be a miracle to discover a member of a genus from which we both arose.Subtribe Paninina :: Pan (chimpanzees)
Subtribe Hominina :: Homo (humans)

A species can't be given a name unless enough actual body parts
(or nowadays, perhaps, genetic material) exists to compare with
related species, and identify it as a distinctly different species.
As Zero One indicates, we have no such body parts, and there is
no way to know if any will ever be found.

No, no. He means CHiPs, the old TV show about the two motorcycle cops.um... its my understanding that "chips" evolved from silicon...

We're scientists here!! We are about the truth no matter how ugly it might turn out to be!!!

Correct me if I am wrong (As usual lol ) But I am sure I saw an updated family tree that suggested we may have split away before the chimps

A controversial subject, even among scientists, as evidenced by this Nat'l Geographic article.
...biologists at Wayne State University School of Medicine in Detroit, Michigan, provide new genetic evidence that lineages of chimps (currently Pan troglodytes) and humans (Homo sapiens) diverged so recently that chimps should be reclassed as Homo troglodytes. The move would make chimps full members of our genus Homo, along with Neandertals, and all other human-like fossil species.

This is just plain silly. We should get rid of this homo nonsense and put us in Pans where we belong.

This site from yale.edu was a real find:
The developing discipline of molecular evolution suggests a divergence of hominids away from pongids as recently as five million years ago. The earliest known anthropoids are 40 million year old (Eocene) forms, found in 1978 in Burma by Russell Ciochon and Donald Savage. Amphipithecus and Pondaungia are believed to be at or near the point of divergence of apes and monkeys. A possible 40millionyear separation in development for apes and monkeys is to be compared with a possible 5 million year separation of the apes and hominids.

Would that then make us Pan sapien?

By a Fortean Coincidence, last month's Scientiifc American included a review of the book, "The First Human: The race to discover our ealiest ancestors" by Ann Gibbons (really! Nominative determinism again?). I haven't read the book, but the review mentions Sahelanthropus tschadensis, "currently the oldest known hominid" at seven million years old. So grandad to both Chimps and humans?

Recent fossils point to MoLarCur as our ealiest ancestor here.
