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.

    Now, as you can clearly see, there are TWO gaps in the fossil record, where before there was only one!

    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.

    If you had read the article - you would know that there were pieces of a large number of individuals found.

    You can assume carbon testing was done, it's routine.

    There's also the issue of associated plant and animal material in the fossil layer - which tends to give credence to the find.

    why is it so interesting to study where humans have come from

    How could you NOT be interested in knowing where humans came from?

    and why exactly monkeys?

    Because both the fossil record and DNA say that chimps are humans' closest relatives, with 96% identical DNA.

    intelligently and in other ways they're totally different

    The intelligence is only a matter of degree, and in many (perhaps more) ways that matter more than intelligence they are the same as us.

    Monkeys have come from somewhere too

    Monkeys and apes (including us; we are an ape species) have the same anscestors, for reasons mentioned above.

  7. Birthers, deathers, and other wingnuts by spun · · Score: 5, Informative

    Birthers are a group of clueless, angry white people who firmly believe President Obama was born outside the US. Deathers are a group, nearly identical in membership, that believes President Obama wants to enact 'death panels' that will deny needed health care to seniors. Most birthers are deathers, and vice versa. They also tend to believe that they either need to secede from the union, or stage a military coup, as the country has now become a communist dictatorship. Hope that helps.

    The human tailbone is most certainly vestigial. Vestigial does not mean useless; it means that it once had a given function (external tail in this case) but no longer performs that function, but does not mean that it doesn't perform a different function. In humans, our coccyx is usually comprised of 3-5 vertebrae, which are usually fused into two or three segments. Not all function in muscle attachment, as is unsurprising given the variability in the structure. People have been born with nine calcified bones in the coccyx (plus cartilaginous structures), and external tails complete with articulating vertebrae (five's the record as far as I know) have been reported in the medical literature. People have also been born without a coccyx at all, although like external tails this is rare. Removal of the coccyx is called a coccygectomy (say that to your five year old!) and can be done on the whole or just a part of the structure with little or no side effects.

    Truly a touching story about Nancy Reagan.

    You might recall that John Hinckley was a seriously deranged young man who shot President Reagan in the early 1980's.

    Hinckley was absolutely obsessed with movie star Jodie Foster, extremely jealous, and in his twisted mind, loved Jodie Foster to the point that to make himself well known to her, he attempted to assassinate President Reagan.

    There is speculation Hinckley may soon be released as having been rehabilitated. Consequently, you may appreciate the following letter from Nancy Reagan to the staff at the mental facility treating Hinckley reports to have intercepted:

    To: John Hinckley

    From: Mrs. Nancy Reagan

    My family and I wanted to drop you a short note to tell you how pleased we are with the great strides you are making in your recovery. In our fine country's spirit of understanding and forgiveness, we want you to know there is a nonpartisan consensus of compassion and forgiveness throughout.

    The Reagan family and I want you to know that no grudge is borne against you for shooting President Reagan. We, above all, are aware of how the mental stress and pain could have driven you to such an act of desperation. We are confident that you will soon make a complete recovery and return to your family to join the world again as a healthy and productive young man.

    Best wishes,

    Nancy Reagan & Family

    P.S. While you have been incarcerated, Barack Obama has been banging Jodie Foster like a screen door in a tornado. You might want to look into that.
