    A 2-million-year-old flat-faced skull pulled from the sandstones of east Africa has shored up claims that at least three species of early humans once co-existed in an "evolutionary experiment" that saw an explosive increase in brain size paired with radically different faces, teeth, and jaws.

    While the new partial skull and two newly found jawbones look radically different from modern humans, they match an enigmatic, nearly complete skull found 40 years ago that paleoanthropologists have long struggled to fit into the human family tree.
    Distinct species

    Together, the new finds and the puzzling skull describe a species of early humans clearly distinct from two others known from fossils from the same period, said Meave Leakey, the 70-year-old paleoanthropologist who led the team that discovered the fossils.
    The "base of the human lineage was indeed diverse," Leakey said from her longtime home at the Turkana Basin Institute in northern Kenya. Her colleagues made the finds near there.
    The new fossil report is bound to stir up more controversy in a field long marked by contention.
    In an e-mail message, noted UC Berkeley anthropologist Tim D. White wrote: "We still don't understand Homo habilis because there are still too few fossils," referring to another group of early human fossils from the region discovered in the 1960s. "This is a field that continues to be plagued by practitioners unfamiliar with the degree to which individuals within species can vary."
    In 2007, an associate of Leakey's noticed a jawbone sticking out of a block of sandstone in the arid region. After hauling the block to their laboratory, the team whittled away with dental drills and revealed a face, its right cheek and upper jaw intact. The small fossil probably came from an adolescent, Leakey's team reports in this week's issue of the journal Nature.
    Partial jawbones

    Nearby, the team also found two partial jawbones that match both the new skull and the mystery skull.
    All of the fossils date between 1.78-million and 1.95-million-years-old.
    At that time, East Africa was a roiling hotbed of human evolution. Other fossil finds show that the long-lived species thought to be our direct ancestor, Homo erectus, thrived in the region, which was undergoing rapid changes in plant cover, rainfall and, in all likelihood, availability of various foods.
    Another, more primitive hominid species, called Paranthropus bosei, also lived in the region at the time. Stout-bodied and with giant molars, these creatures more closely resembled the more ape-like creatures known as the Australopitecines and are not thought to be human ancestors. Instead of evolving, they died out.
    But the new finds - and the mystery skull - clearly don't belong to any of these groups, said Leakey, who is also a National Geographic explorer-in-residence.

    Chronicle Science Editor David Perlman contributed to this report.

          Hobbits are specific to LOTR, elves and dwarfs are a universal constant, like someone born humble, but who really turns out to be a king/magic/only person who can weild the magical thingamejig and having to go on a long journey with a bunch of diverse characters with different skills and specialitites

                  Oh I know full well that Hobbits are ment to represent the architypal ennglish man, the shire is also an idealised english countryside. That they turn out to be the real heros is not in anyway related to JRRT being english either

                  I just don't have hairy feet and I'm 6 foot tall, maybe I'm 2 hobbits taped together and shaved

                          Well ... I'd think the Shire (insofar as it is anything other than itself) would tend to be more representative of the smaller West Midlands counties. That's the part of the country he grew up in. He also spoke of that particular countryside being "shabbily destroyed" -- meaning, I guess, not so much by the Great War, though that did shake things up, as simply by the advance of modernity.

                          It think it would be something of a sentimentality to see Britain as whole -- the political unit -- pre-1914 as the Shire, since at that time it was one of the most, possibly the most, powerful countries, militarily, industrially, and financially on the face of the globe. And I doubt Tolkien would have been guilty of sentimentality.

                          But it's certainly possible to read a lot of things into the book. I guess properly speaking it's his "legendary" material, and the myth proper is elsewhere, but it has something of the openness of myth -- it's not that anything "is" precisely anything else, but that you can see many echoes in it, some of which he probably intends to be there.

                          There are interesting echoes from Old Norse material, too. (Tolkien was a scholar of Old Norse, of course.) This is some of the same material that Wagner used. So we have "the ring". Interesting that it lengthens Bilbo's days while making him "thinner" -- more wraith-like. It's tempting to see the ring as suggestive of power -- particularly perhaps scientific/technological power. I think you could ask from a "Primal" perspective whether a person in a technologically advanced society kept alive by medical advances but living a not particularly full life from which a sense of purpose is vanishing is better off than a hunter-gatherer. And I don't think Tolkien would have been unsympathetic to that.

                          Nor, I'd suggest, would have been his friend Lewis. Lewis's Sci-Fi novel Out of the Silent Planet has some extremely funny parody of the incomprehension of technologically advanced but greedy and rather philistine people confronted by a harmonious and pious primitive society:
