New Study Suggests Humans Lived In North America 130,000 Years Ago (npr.org)

An anonymous reader writes: In 1992, archaeologists working a highway construction site in San Diego County found the partial skeleton of a mastodon, an elephant-like animal now extinct. Mastodon skeletons aren't so unusual, but there was other strange stuff with it. "The remains were in association with a number of sharply broken rocks and broken bones," says Tom Demere, a paleontologist at the San Diego Natural History Museum. He says the rocks showed clear marks of having been used as hammers and an anvil. And some of the mastodon bones as well as a tooth showed fractures characteristic of being whacked, apparently with those stones. It looked like the work of humans. Yet there were no cut marks on the bones showing that the animal was butchered for meat. Demere thinks these people were after something else. "The suggestion is that this site is strictly for breaking bone," Demere says, "to produce blank material, raw material to make bone tools or to extract marrow." Marrow is a rich source of fatty calories. The scientists knew they'd uncovered something rare. But they didn't realize just how rare for years, until they got a reliable date on how old the bones were by using a uranium-thorium dating technology that didn't exist in the 1990s. The bones were 130,000 years old. That's a jaw-dropping date, as other evidence shows that the earliest humans got to the Americas about 15,000 to 20,000 years ago. The study has been published in the journal Nature.

  1. Smithsonian Barbie by pipingguy · · Score: 5, Funny

    Thank you for your latest submission to the Institute, labeled “211-D, layer seven, next to the clothesline post. Hominid skull.” We have given this specimen a careful and detailed examination, and regret to inform you that we disagree with your theory that it represents “conclusive proof of the presence of Early Man in Charleston County two million years ago.” Rather, it appears that what you have found is the head of a Barbie doll, of the variety one of our staff, who has small children, believes to be the “Malibu Barbie”. It is evident that you have given a great deal of thought to the analysis of this specimen, and you may be quite certain that those of us who are familiar with your prior work in the field were loathe to come to contradiction with your findings. However, we do feel that there are a number of physical attributes of the specimen which might have tipped you off to it’s modern origin:

    1. The material is molded plastic. Ancient hominid remains are typically fossilized bone.
    2. The cranial capacity of the specimen is approximately 9 cubic centimeters, well below the threshold of even the earliest identified proto-hominids.
    3. The dentition pattern evident on the “skull” is more consistent with the common domesticated dog than it is with the “ravenous man-eating Pliocene clams” you speculate roamed the wetlands during that time. This latter finding is certainly one of the most intriguing hypotheses you have submitted in your history with this institution, but the evidence seems to weigh rather heavily against it. Without going into too much detail, let us say that:

    A. The specimen looks like the head of a Barbie doll that a dog has chewed on.
    B. Clams don’t have teeth.

    The car was co-invented by the German Mr. Daimler and the American Mr. Chrysler.

    The light bulb -- that's easy, that was invented by Henry Ford, the founder of the Ford Motor Company, where it was incorporated into their advertising as representative of "Ford has a better idea!", such as their innovative double-clutch transmissions conveying the necessary impression of cheapness for their small cars to encourage the sale of their Lincoln Navigator as being "more solid."

    Samsung in Korea invented the phone.

    The computer was invented in England by a guy we don't want to talk about.

    The steam engine? That's easy -- it was invented by Montgomery Scott, supported by his Irish-Jewish friend Cap'n Kirk.

    "Another problem is that due to interbreeding between "Native Americans" and Europeans who arrived within the past 500 or so years, many of today's "Native Americans" actually have significant European ancestry. "

    But just try to find a Native American who brags about being one-sixteenth Belgian.
