Missing link found?

From Missing Link: Scientists In New York Unveil Fossil Of Lemur Monkey Hailed As Man’s Earliest Ancestor from Sky News:

Scientists have unveiled a 47-million-year-old fossilised skeleton of a monkey hailed as the missing link in human evolution.

Ida - the missing link?

This 95%-complete ‘lemur monkey’ is described as the “eighth wonder of the world”

The search for a direct connection between humans and the rest of the animal kingdom has taken 200 years – but it was presented to the world today at a special news conference in New York.

The discovery of the 95%-complete ‘lemur monkey’ – dubbed Ida – is described by experts as the “eighth wonder of the world”.

They say its impact on the world of palaeontology will be “somewhat like an asteroid falling down to Earth”.

Researchers say proof of this transitional species finally confirms Charles Darwin’s theory of evolution, and the then radical, outlandish ideas he came up with during his time aboard the Beagle.

Sir David Attenborough said Darwin “would have been thrilled” to have seen the fossil – and says it tells us who we are and where we came from.

I’m sure this will be a hot discussion topic in the blogosphere.  But I have a few reservations, specifically about how this thing is being presented.

Were we really just missing one piece that would single-handedly prove the theory of evolution (at one point, the article’s author calls it the “final piece of Darwin’s jigsaw”)?  I’m sure it will be incredibly valuable for science, and it’s wonderful that it’s yet another prediction fulfilled for Darwin’s theory, but it seems to me that heralding this as the Proof of Evolution 1) trivializes too much perfectly good evidence already extant in favor of common descent and 2) overstates what science can and can’t do — namely, definitively “confirm” anything.  Most scientists I am familiar with never make such extraordinary claims, so I think this kind of talk within that article is probably mostly due to sensationalist, and badly informed,  journalism.  For instance, the title – “man’s earliest ancestor”?  Um…no…that would be a single-celled organism hundreds and hundreds of millions of years before Ida.

One thing’s for sure — even if the academic community accepts Ida for what Attenborough and the others in this article claim it to be, it won’t be convincing anyone who’s already decided for religious reasons s/he doesn’t want to be descended from primates.  But here’s hoping lots of interesting and useful information does arise from what definitely appears to be an important missing link in our ancestry.

[UPDATE: I found a much more scientific and measured description of this same fossil and its importance.  Check out this article from UPI and compare.]

    I agree with you 100%. We didn’t need this fossil to “confirm” common descent, I think that is pretty well settled. Indeed, from my totally paleontologically ignorant position, I don’t see why this fossil would add much at all to that picture. Anyway, statements like that are just asking for it, when we discover it is not an ancestor of ours, creationists will have a field day since this was our “one proof”.

    “Researchers say proof of this transitional species finally confirms Charles Darwin’s theory of evolution”

    Which researcher actually said this? And can I guess he was set up with an loaded question.

    Yeah, notice my update to the post in which I link to a much more sensible article talking about the same discovery in a much more reserved and scientific way: http://www.upi.com/Science_News/2009/05/18/Fossil-find-may-be-monkey-human-ancestor/UPI-19881242660948/

    I felt the same thing. These first articles were totally overhyped, almost to the point of being easy targets for the ICR, AiG, and RTB and DI crowds to portray evolutionists as “grasping for straws” — as if now we have it! All this thing shows, is what we have known for decades, that all primates (old-world/new-world) share a single common ancestor. Really? Can you say GULO mutation? This gun has been smoking for years.

    Very interesting. I’d love to see more discussion of why this fossil is considered such an obvious “link” and how it was dated and such. Because to me, and uneducated individual in this field, I find statements and statistics less than helpful because of the wildly sensationalistic nature of these kinds of claims.

    Is there more data on this thing?

    Guys…help me understand. The Sky News article dubs this fossil “the eighth wonder of the world” while the BBC News web site tells us that the fossil was “discovered in the 1980′s in a fossil treasure trove called Messel Pit, near Darmstadt, Germany…it has been in a private collection.” Knowing nearly nothing about the process of paleontology, why does something so significant take 20 years to debut? Pace of research? Or, are these types of links commonplace and not typically front page news (well…until a museum or a mayor want the coverage)?
    Just trying to be prepared for anti-evo friends and their comments…

    Gordon, re: looking like evolutionary science is “grasping for straws”, I think you’re right on. But if the scientific community awards this find the place Gingeric (who is no less significant than the president-elect of the (Paleontological Society of the United States) claims, it will make selling the tree a lot easier to those who have been told there is no trail of our ancestry in the fossil record.

    Luke, I found this, the original, serious article describing the find in detail. It might be a little technical, but maybe it’ll address some of your questions.

    Amy, the story was that after it was discovered by an amateur fossil hunter, it was sold to the “mystery German collector” and kept on display in his home; the buyer did not recognize its value or import for taxonomy and the ancestral tree of primates. I’m not sure why that alone should earn the scorn of anti-evo folks; it happens all the time with priceless art.

    You asked, “Or, are these types of links commonplace and not typically front page news (well…until a museum or a mayor want the coverage)?” That’s certainly the case. In this instance, because of its apparent significance, it was unveiled by a triple whammy consisting of a press conference, a TV documentary (coming out within a week, I think), and a book just released today.

    The term “missing link” bothers me for a number of reasons:

    1. It conjures up an image of an evolutionary chain, where organisms goes through various stages on their way to becoming human. That’s bad science.

    2. It makes it sound like there was just one thing we didn’t know before about human evolution, i.e., there was one gap in the fossil record. There are many such gaps, and finding new transitional forms plugs them up, but it’s not like the paleoanthropologists are all looking for a new job now that we’ve found the “missing link.” There’s a lot of work to be done.

    3. It doesn’t specify what level of taxa (or clade) the fossil links us to. Ida links us to more primative primates. Great. Now what about the links between those primates and the earlier mammals, reptiles, amphibians, etc.?

    AMW, agreed on all counts. More typical creationist obfuscation. The “no transitional forms” mantra is repeated ad nauseum, and every time we produce one, they invariably ignore it and ask for the missing link between that one and the next one. Of course, scientists look for such “links” as well, but at least they don’t automatically assume that pronounced gaps between transitional forms (if you want to call them that) are proof (?!) that there are no such forms.

    It would be impossible to tell if any given fossil belonged to a species that was ancestral to animals living today. And even then, it would be impossible to tell if any given fossil was the actual individual who provided genetic material that exists to this day. Indeed, I might be a direct descendant of said individual’s brother, and yet said fossil might have died without ever having any children.

    We can’t affirm it in the positive but I would think you can affirm it in the negative. Ida is NOT an early ancestor of ours. Ida died a juvenile and had no children.
