    We've had our first missing link of 2010.  What, you ask?  Was the missing link not discovered twice even last year?  Well, yes, if you read the mainstream media it happens quite often.  And it is happening again this week so look for plenty of news reports.

    But just in case you are out there and need to write one of your own, here is a handy template you can use, based on my experience.

    **********

    The Mainstream Media Missing Link Article Generator

    University of ________ scientists say they’ve found a “missing link” that could help to rewrite the history of human evolution. 

    Experts called it (exciting/wonderful) and said it fills a crucial gap in the fossil record.  The ___ million-year-old creature was not a direct ancestor of modern humans but will allow scientists to answer key questions about what our early ancestors looked like, said researcher ________.    If it is confirmed as a missing link between __________ and __________, it would be of immense scientific importance, helping to fill in a gap in the evolutionary history of modern man.

    Professor _____ _____, an eminent _______ at ______  University who wasn’t involved in the research, welcomed the find.  “The discovery is the most important find since ________ and fills a critical evolutionary gap,” he said.  

    _______ and ______ experts have remained silent about the exact details of what they have uncovered, but the scientific community is already (abuzz/alight/aflutter) with anticipation of the announcement of the find when it is made on ________.

    Clever, right?   Well, I am not the first one to do it.   Science detractors have created dozens of these because the mainstream media makes it so darn easy by claiming finds of unconfirmed lineage and composed of numerous skeletons are 'missing links'.   It's really a disservice to the public because it erodes confidence in science.

    So what do we know about this new find, other than headlines like Missing link between man and apes found in The Telegraph?   Well, not much.   It has no name - and we know that can be a problem - and few have seen it outside Professor Lee Berger's team from the University of the Witwatersrand, who found it a limestone cave known as Malapa cave in the Sterkfontein region of South Africa near Johannesburg.

    The Telegraph describes is as an "almost-complete fossilised skeleton" but people need to understand this is a not a preserved skeleton, instead it is a composite of individual fossils found in the same area.    We also know that "a major media campaign with television documentaries is planned" which is a red flag for scientists but doesn't disqualify the significance of a find.  Disclosing there will be a documentary before it even has a name is odd.

    Obviously fossils with convenient links between Australopithicus (Australopithecus anamensis, Australopithecus afarensis and Australopithecus africanus), 4 million years old or so, and modern humans (Homo habilis some 2.5 million years ago) would be terrific, though not really necessary.  Paleontology is not some Supreme Court of science in which nothing is valid unless a fossil is found.  Fossilization is a tricky process, after all and doesn't happen in convenient linear timestamps.

    And there are debates about where a 'missing link' would fit anyway - some hominins have been found that are older than the youngest common ancestor our gene clock says should exist on the time between the split of humans and chimpanzees.   But the debates are the strength of science, not a weakness and biology will converge on better answers to crucial questions - it does not take a 'paleo-anthropologist' to confirm it.

    So enjoy the media hype this week.   For every skeptic who uses the media frenzy without any independent confirmation as a weapon against science, dozens more will be fascinated by the search - the destination may be unknown but science is a terrific road to travel.

    Remember that examples of the Neanderthals had cranial cavities exceeding 2200 cc.s

    One has to ask the question, Hank is the "missing link" from a human perspective an infinite regression that will never end?

    Patrick,

    You might not be too far off the mark. According to a recent documentary (and lord knows how much of their homework they did) Ghenghis left no monuments but did leave a huge DNA footprint.

    He slept his way through much of the female population during his reign and is related to one in two people in Asia or some fantastical number.

    That's interesting, Heidi. Talk about promoting your own genes! Looks like he was working over time! LOL ;-)
    It's funny. I was just joking around with my wife about how the media always makes that big "missing link" slpash every time yet another hominid fossil is discovered - heck, any fossil of a new species of anything. It's as if the media is still veinly beating their collective head against the wall trying to convince creationists of evolution. I have some news for them: Ain't gonna happen. We have all the "links," and more than enough evidence all told, to positively and undeniably assert the fact we humans are products of evolution just like everything else in this changing universe. So, while it's great when we have more finds like these to help fill in the blanks, unless we fill in every blank ever, find the fossils of every living thing that ever existed, we'll never change the minds of the creationists. Instead of "missing link," they should just call it what it is: Yet MORE Proof of Our Evolution.

    Doesn't matter how many "intermediate forms" get dragged out of the ground, nothing will convince the stubbornly Unconvinced. Took me a lot of reading to get over the "personal incredulity" hump that eroded my confidence in the Doubt Peddlers. Of course now I understand the technical nuances that Cretinists use to raise Doubt and, more importantly, I distrust the whole "faith process" that plays on our tribal instincts. Do I have to "just believe" any claimant to "absolute truth"? Nah. Scientific method means I can put them all under the microscope... including the method itself. Guess which one loses?

    Hank
    Indeed, they pick and choose aspects of the scientific method for no reason other than to raise doubt, and then colloquialize others, as when they say 'it is just a theory' without realizing what a theory in science is. The media do us no favors with these headlines but they are not anti-science. I have to assume Richard Gray, science correspondent at The Telegraph who is linked to above, can't be happy about his byline on that piece, other than getting paid to have his byline on anything they choose to edit and put up. Everyone is happy about getting a paycheck.

    I'm beginning to put "missing link" in the same category as "soul mate." I have friends who've dated five or six plus in their time. Just how many souls do you have?

    Great article. ; )

    p.s. Piggie DNA analysts working out the genetic similaries in the missing link model.. one more piece of solid science.
    Heidi,

    I don't think it's a question of the number of souls, but the number of mates, and you can find the answer using a simple equation.

    §+(ð*π)/ξ = 1

    where § = your soul
    ð = number of soul mates
    ξ = number of Bon Jovi songs you know the words to

    For women, you have to take the entire left side of the equation and multiply by two since most are two-faced (I kid?).

    I can't wait for the headline proclaming:

    "Missing Link Discovered to Not Really be Missing!"

    I see a competition looming:

    Missing Link Discovered_________

    The odds are, strictly speaking, against any fossil being ancestral to any living species, since most lineages go extinct. But try explaining that to Joe & Jane Public.

    The mainstream media certainly are to blame for much of the nonsense spewed forth about these finds, but you cannot blame the hype solely on the media. Science and Nature both encourage this ridiculous mulitplicity of human origins by featuring every new species--named by the authors/discoverers, and NOT the media--as the featured "cover article." How many times has either of these journals featured the discovery of "another" or the second find? The ultimate responsibility falls on the shoulders of the anthropologists engaging in the pseudoscience of cladism, trait analysis etc who insist on assigning every new specimen to a new, previously unknown, species. And when Henry Gee of Nature states (see the documentary on the Flores finds) "There are dozens of species out there for which we have no evidence" you simply can't fault the ill-educated media mongers. That's the head honcho of Nature making a statement publicly that even the Big Foot/Alien Abductee/Crop Circle morons would find to be bad science. Too bad, too, because it costs the students of human evolution a lot in terms of credibility and the human fossil record really does reveal a lot about the history of the human lineage. It just doesn't support the contention that there 15, 20, more species of humans overlapping in time and space. It doesn't help that individuals placed in powerful posts at respected museums (like Tattersall, for example) subscribe to this rank idiocy.

    Hank
    Nicely put.  Your comment is better than my article, actually.
    Spoken like a true Lumper. Of course if you found a fossil hominid would you name it a new species too? Or try to fit it in to a known one? Tim White, in the context of "Kenyanthropus" made an impassioned argument that it was a known species which had been distorted via matrix intrusion and expansion of the fossil - there's a lot of quite dramatic variation in living species, let alone fossil ones. Yet when "Ardipithecus" is unleashed on the world he's a "splitter" like everyone else. Maybe he's right with "Ardi" but it's a thin-line anthros tread when describing a new find.

    Your comment assumes that being a "lumper" or a "splitter" is the only choice available. I reject thedichotomy as a falsehood, every bit as much a straw man as the nature/nurture argument. You ask if I'd name a new species or assign a specimen to a known species. I don't have a pre-fabricated answer to that because I simply don't assume beforehand that there are dozens of "unknown" species out there. Why would I impose such a presupposition on a fossil that hasn't yet been found? This is what passes as science in paleoanthropology? And, I don't regard the elaboration of taxonomic relationships to be the sole, or even the principal. or even a particularly interesting goal of evolutionary biology--sorry, that may be too stringent a requirement, let me rephrase--I don't regard the elaboration of taxonomic relationships to be the goal of anthropology (there's so very little that's biological about these reports). So Mr. Berger reports a new species, Au. sediba. Great. But what, now, do we know about the processes of evolution that we didn't know before? How is our understanding of human biology, australopithecine biology, natural selection, of, well, anything, enhanced? What anatomical evidence is there in sediba which can be "read" to elucidate the mechanism by which this new species was isolated from all others? Explain the process to me by which this animal, coexisitng with god alone knows how many more Gee-Spoor-Leakey-species existed as a real and separate biological entity. What evidence is there that this new specimen possess traits which exceed the known ( and we don't know much) variation of, say, africanus? What genetic/developmental mechanisms will you invoke to explain the development of the traits assumed to be evidence of this new variation? That, of course, is too much to ask of an anthropologist. But,oh, right, we now have another new species. That's it? That's the discovery?The anthropological contribution to human understanding? It seems such a terribly impoverished intellectual discipline, hiding behind an impressive array of trait lists, and graphs depicting the loading of a molar cusp height on the third principal component, etc. The problem is that the issues of human evolution are still regarded as an anthropological problem instead of, as with every other organism on the planet, a problem of biology. This is nought but re-tooled archeology, replete with the typology of old; the same approach to fossil skulls that archeologists have applied to sorting out flint chips. Typological, pre/anti evolutionary, 18th century science, at best. With, maybe, a little outdated mendelianism thrown in, for the sake of looking scientific. Dig the fossils, man. Thanks for your fine work. Now go sharpen your shovels.
