Oldest Human Fossil Fills In 2.8-Million-Year-Old Gap In Evolution 94

GeekyKhan writes Archaeologists have unearthed a human jawbone—with teeth-- that is believed to be the oldest remains ever found from early humans. It belonged to the earliest specimen of Homo and dates back 2.8 million years. From NPR: "Although it's risky to say you've got the first or oldest of anything, Brian Villmoare, a paleoanthropologist at the University of Nevada, Las Vegas, is sure he and his team have the earliest specimen of Homo, the human genus. 'Oh, yeah, it definitely is,' he says. 'We were looking for it — and by miraculous chance we happened to find it.' Villmoare and an international team from the U.S. and Ethiopia found a lower jaw with five teeth in a region of Ethiopia called Afar. They were working a hill that was full of fossils. 'I was on the other side of the hill,' he recalls, 'and they said, 'Brian! Brian! Come over here.' The partial jawbone — just the left side – was lying on the ground, having eroded out of the hill. Several dating methods confirmed its age as roughly 400,000 years older than the previous record for a human-related fossil."

    This particular gap has become two gaps.

      Just like global warming the "scientists" keep changing the data and models. This is not science, science is only clear cut provable and reproducible common sense facts. How can anyone believe this is not just a huge scam from money-grabbing scientists.

      Well, to a creationist, the fact that there are no intermediaries between you and your parents is proof that you are not related.

        And the "logic" behind that "thinking" is risible.

        "Irreducible complexity" is the same as "I can't figure out how it happened so God must have done it!" As if the limits of one's intellect constrain reality. Talk about intellectual arrogance.

          Clarifying the argument: It is not merely "I can't figure out how it happened". It is "If *I* can't figure it out, no one can, because I am the brainiest, wickedly smart, scientist ever to have walked on this planet".

        To the religious fundamentalists, this is just more proof that Satan and his evil hoardes place false evidence to lure those whose faith is not solid away from Biblical truth.

          It is not just Satan who is planting all those evil evidence. Satan is being actively aided and abetted by the Omnipotent who is *not* removing the false evidence as soon as Satan does the planting. It am sure the Omniscient All Knowing God is just testing the faithful to find out how strong their faith is, which He already knows, by definition.

At just 4 surviving children per parents, using 33 years per "generation", you easily hit 8 billion in 1000 years.

        You mean that the best possible model is statistically significant? Wouldn't you think there is a higher possibility that the population growth is not exponentially at all times? Surely, there are lies, damn lies and statistics.

    • On the other hand, humans and dinosaurs cohabit right now. I'm looking at a Cyanocitta cristata (bluejay) out my back window right now.

      Yes, bluejays are dinosaurs, at least since they moved Aves into Dinosauria.

      Which makes the fundies right for the wrong reasons. It would drive them even more crazy if you pointed out that birds evolved from dinosaurs, eh?

    every time "missing gap" is used to discuss/describe evolution. We will never find all relevant fossils. Most intermediate iterations were never fossilized in the first place. The "fossil record" can never be complete. All we can do with the infinitesimally small percentage of fossils we do discover is use them to confirm, or refute, the theory of evolution as it currently exists, and, perhaps, revise the theory as required to account for new discoveries and observations. Science!
