Should We Boycott the Brainless?

Tuesday, September 23rd, 2008

Note: This is one of the places that I learned the lesson I am trying to share with other self-proclaimed skeptics today. So, if your kids are fearing sculptures of DNA, now’s your chance to learn well the lesson of Poe Read below for more details.
(Article Updated below!)

I’ve advocated boycotting stores that support evangelical right-wing fundamentalist entities,1 and I firmly believe in doing everything possible to remove the taint of religion from the decision-making process of government and its presence in our law, public schools, and courthouses. I’ve also asked the question, how far should we rational thinkers go in countering religion?2

Today, I ask, should we also figure out who the brainless are, and boycott them, even if they’re not politicians or evangelists or school board members?

What if you were fond of a certain actor’s work, and you read an interview where that actor was asked, “When was the earth created?”, and the actor responded, “about 4000 B.C., but possibly 10,000 years ago”? Would you seriously consider not watching movies in which that actor starred? Take, for example, Tom Cruise, who, at least publicly, asserts the belief in the existence of an alien being god-equivalent, and all the other nonsense with which Scientology brainwashes its victims.3 Certainly, he got some heckling and negative reaction to his odd behavior and beliefs, but that didn’t incredibly diminish his standing as a Hollywood A-Star. Where he truly got criticized, though, is when he tried to tell others how to live their lives — don’t take pharmaceuticals; don’t see psychiatrists, etc. That imposition on his part was the equivalent, to many, of an offense.

Something gave me a slight shock today. It was the same shock I endured when I read about Ben Stein (whom I actually enjoyed as the brainiac on Win Ben Stein’s Money) extolling the virtues of his pro-Creationist movie Expelled. I had thought to myself, “This must be a joke.” After I was convinced that it wasn’t, I told myself that I’d do my best to avoid ever sending that man a dime. Today’s shock was similar, and I’m curious as to whether there is or should be a distinction that would discourage me from employing the same reaction.

Q. When was the earth created?

A. Archbishop James Usher, working out a chronology from the Bible, calculated in 1654 that the earth was created on the night of October 23, 4004 B.C. Other timetables reach back as far as 10,000 years.

Who answered this way? A priest? An evangelist? Sarah Palin? It could have been any of those, and more. But what’s shocking is that it was uttered, as it were, by the Pulitzer Prize-winning American film critic and screenwriter Roger Ebert.

“What about oil and coal…?”, he’s asked. “They are evidence of a Great Flood,” he replies. Apparently he firmly believes that a fossil claimed to be 200 million years old shows a shoe print, proving that all layers of sediment were laid down all at once, about 4,400 years ago.

Neanderthal and Cro-Magnon Man? “Created at the same time as man.”

And 600-year-old Noah had an Ark filled with pairs of 5,400 land-based mammal species, plus eight people (from whom we are all descended). Dinosaurs walked the earth with man, but drowned in the Flood. 4

At first, again, I thought this was a joke. This couldn’t be Roger Ebert’s own website! I opened a new browser window, typed in “rogerebert.com” and clicked my way back to the Commentary. Okay, it could be a hack attack, sure, but this time, there’s no Rickroll, and it coincided with Ebert’s Roman Catholicism. Fine. He’s a young-earther. The question, though, is whether I should ever listen to the man’s suggestions again. It’s not like I was previously an Ebert fan, but I did occasionally catch his show and I listened. Now he has books and other writings about movies.

Should my rejection of his beliefs as being brainless give me reason to reject everything about him? If yes, then is it my responsibility to determine the world view of anyone with whom I interact, in order to accept or reject that person? If no, then where do I draw the line, and why? I know that when I see a Televangelist, I reject that person by changing the channel (and usually by griping). Someone like Sarah Palin, who is oh so objectionable for many other reasons, I initially reject based on her biblical literalism. Even if she appeared experienced and wise in other matters, I probably wouldn’t want her visiting my home or serving as Vice President if she outwardly (and more frighteningly inwardly) believed in and advocated belief in Creationism.

So, is my line a finely drawn one, based exclusively on whether a person is using belief to infringe upon my way of life, or is it a broader, grayer line that also includes rejection based on affiliation as well as infringement? Is the latter sort of line an acceptable one for someone who purports to be a rational thinker? Perhaps I favor the latter because the mere existence of those who believe in such nonsense are a potential threat, whether direct or indirect (I mean, they make lots of babies, and they indoctrinate those babies in “the way,” so the threat of suffocation by superpopulation could warrant some reaction). I think I honestly could use a bit of guidance on this issue.

UPDATE:

Invisible Quotation Marks

This seems to be a Poe’s Law trend. I wonder why.

Apparently, on his online journal, Roger Ebert has written a scathing rebuttal to the criticism and misunderstood responses filling the web full of vitriol over his pro-Creationism FAQ, stating that his purpose in writing the apparently facetious FAQ was to “to discuss the gradual decay of our sense of irony and instinct for satire, and our growing credulity.”5

Bravo?

It seems Ebert was more than disappointed with evolutionists, who took him at his word (how dare we!), when he concluded, “The adventure with the Creationism article has been enlightening, and a little depressing. I expected better from evolutionists.”

To his credit, however, he did admit not being aware of that little nugget of emoticonology that would have made the distinction between what’s commonly accepted as blind faith and extremely subtle satire, described by Poe’s Law. Ebert wrote, “A postscript and confession. As I said, everyone has blind spots. Many of my supporters cited Poe’s Law, which I was completely unfamiliar with.”

So, the scoreboard for Roger Ebert looks a bit confusing. +10 for decent movie reviews, -10 for wacky Creationist rhetoric (without even a hint of invisible quotation marks visible to anyone but six of his loyal readers?), -10 for insulting the rest of us for not “getting it”, +10 for admitting that maybe we had a pretty good reason for not “getting it” (via our dutiful nod to Poe’s Law), and perhaps +5 for taking the time to explain his reasoning in a lengthy and descriptive journal entry. So, Mr. Ebert, I leave you with +5. And I probably won’t boycott you, since I think your intentions were ultimately good.

One thumb up, one thumb kinda sideways, unsure of where to point.

What’s even more enlightening is the variety of responses to Ebert’s journal entry, ranging from “Oh, I knew what you were doing,” to “I honestly thought you might be telling the truth.” I’ll quote a few excerpts (all from the same page):

As you mention in your article, I did see the quotation marks in your article. But it was based on a ridiculously thorough reading of your previous writings (I haven’t taken the time to search your reviews for the term ‘Creationism’ but I am positive you’ve slighted the concept previously). I knew enough to think “This is so inherently ridiculous that Roger does not need to add any text stating so.” But I will confess that if I stumbled upon the article without a diploma in Ebertology, I’d have been duped. The old adage “Consider the source” made me look smart.

Oh, and in later the same thread, I bemoaned your use of an emoticon as the fall of the last bastion of grammatical holdout. Now I see that it may have been a concession to the above. -Mike S.

Mr. Ebert:

Point taken.

You actually had me going for a while.

However, the problem as I see it is that your satire was indistinguishable from the real thing. Creationists actually believe this nonsense, and they repeat it constantly.

As such, there was reason to believe that you actually believed what you wrote. Especially for someone like me, who had no idea about your actual position on the matter.

You could of course counter with “why didn’t you research it, then?”, to which I reply: Because, again, what you wrote was what a creationist would have written. -Wapper

The problem with the article is that it mimics claims made by Creationists perfectly. That’s not satire. Satire contains an element of the absurd; Creationism is already absurd, recited with a straight face.

By your own standards, we should regard Ben Stein’s EXPELLED as satire. After all, we have a preconceived notion of Stein from his Comedy Central game show. Shouldn’t we expect him to be reasonable? I did. I think my preconceived notion of Stein was valid, which explained the almost universal surprise when his movie came out. Nobody expected Stein to take up such an insane stance. My reaction to your own article was the same: I can’t believe it, but I’ve seen smart people say the same dumb things before. -John W.

I’ll admit, Mr. Ebert, I was so busy worrying about the thought that one of my favorite intellectuals had gone over to the academic dark side that I missed the quotation-marks. I think Poe’s Law is a very apt observation (second in importance to all-wise Godwin’s Law). When such an emotionally charged issue as fundamentalism vs. empiricism arises we tend find ourselves blinded by our gut reaction, forgetting there’s probably a “wink wink, nudge nudge” in there somewhere. In retrospect, I can look over the article and crack a grin at the absurdity of believing that you had jumped the fence. Comments like Noah’s age, and your “steadfast” belief in the story of the Ark, combined with your assertion that man and dinosaur had roamed the Earth at the same time should have slapped me into awareness given your past articles. -Gene D.

Do you really believe that any of what you have written is outlandish enough to pass as satire in an age when 67% of Americans believe in the existence of angels and you have a woman running for vice president who’s a member of a cult that speaks in tongues ?
I say you are entirely out of touch with the reality of relgious thinking in this country. -Issitoq

One need only look at the reaction to the recent New Yorker cover featuring the painting of the Obamas to see that we’re living in a world where irony, sarcasm, and satire are no longer appreciated. As an Obama supporter, I thought it was a brilliant counterattack against the types of people who believe and perpetuate the crazy rumors about the Obamas, and I was sure the readers of the New Yorker would feel the same. But, I quickly realized that many didn’t get the joke, and many of those who did were still incensed because they felt that the Obama detractors wouldn’t—and would just use the cover to further their own cause. I just sighed with disappointment as I wrote this. -Jason

so basically you were trolling. How “clever” of you. And yes, i meant you to see the quotation marks there. -Ian Rennie

Roger, I’ve been a devoted and regular reader of your site since I was 13 years old. I know full well what you think of creationism and your love of all things Darwin since you’ve mentioned it many times- and your article confused and shocked ME!

You really had me worried for a few minutes and I knew what you thought of evolution vs. creationism and figured it *had* to be satire- so you can’t blame other readers.

Now, I knew that you must have been being ironic since I knew you couldn’t possibly be serious but I didn’t see the joke, try as I could. It sounded like you were being serious.

Except for the moose line, that is.

It’s not a good joke if even people who know you have to be kidding don’t understand it. -Agatha

Ape to Man: a 300,000 Generation Family Reunion

Saturday, December 29th, 2007

Imagine, if you will, the diversity in that group photo! The History Channel’s 2005 documentary, Ape to Man, attempts to recreate just that in a handy, 100 minute film. We learn of the struggles of the dedicated men who sought to answer some of the most fundamental questions of human existence… Who are we? Who are our evolutionary ancestors? Where on Earth do we come from? As the film explains within the first few minutes, for ages, we had no scientific explanation for these questions. That is, until the discoveries made over the last century by the scientists who risked much to bring us such revelations.

The film highlights a number of fossil milestones that mark various points along the 3 million year procession from ape-like creature to human-like protoman. It also unearths the controversies faced by those that made the discoveries, and the social climate at the time of their introduction into the scientific world. The first fossil is discovered in 1856 by a limestone harvesting crew in a cave in the Neander Valley, Germany. What is originally thought to be a piece of skull of a modern day murder victim is brought to the foreman’s attention, and is, amazingly enough, almost discarded. At the last minute, though, he instead decides to show it to a teacher friend of his he believes might have some interest in the item. The “murder victim” turns out to be a 40,000 year old skull of the hominin that is later named (you guessed it!) Neanderthal.

The interesting part is the initial hesitance on the part of the Victorian scientific community to identify this find as a new species of man. The skull is, at first, thought to belong to a barbarian that fought the Roman legions, the victim of an unknown congenital deformity, even a lost Russian Cossack. The high school anatomy teacher that retrieved the skull fragment is the first to suggest it is an ancestor to man. To most of the population at the time, this idea was absurd. Three years later, Darwin’s “Origin of Species” is published, and popular opinion regarding Neanderthal begins to change. We begin also to attempt to flesh out our family tree, and the race is on to become the first scientist to discover the “missing link,” an animal more exactly between ape and man.

That is not to say human obstinance does not play its own part in hindering the scientific process… The desire to place this “missing link” in Europe leads to one of the biggest blunders of all time in the search for our true ancestor. Piltdown man, presented before the Royal Geographical Society in 1912 by Charles Dawson, was the ideal candidate for such a creature. Its brain was large, like a human being’s, and its jaw was primitive like that of an ape. Aside from that, it was discovered in England, which is what seems to have primarily cemented its place in history. This meant our origins could be traced back to Europe, not Asia, as was previously thought, and therefore appealed to the British scientific minds of the time. Because the find was so popular, little digging was done to verify its authenticity. Decades pass before the truth is realized.

When a true contender to the throne, Taung child (or Australopithecus africanus) from South Africa was discovered by Australian anatomist Raymond Dart in 1924, it nearly devastated his career. The initial introduction of the first human ancestor to come from Africa known at the time (and earliest, at over 2,000,000 years old,) was met with much opposition. The small brain and fine teeth of Taung did not fit the mold of what scientists wanted. One London scientist who reviewed Dart’s find placed it in the same family as gorillas without having actually seen the fossil for himself. 25 years pass until Dart and his fossil gain the recognition they deserve.

In 1953, 40 years after Pildown’s ascension to the role of “missing link,” the fossil is examined scientifically for the first time. It is finally proven to be the hoax that it has been all along. The celebrated jawbone, is, indeed from a modern ape that has simple had its teeth filed down.

The tale told of our rich history (both ancient and modern) in this film is both fascinating and, well, humorous! It goes to show that even in the face of some our greatest discoveries, human selfishness has the ability to be one of our greatest downfalls. Even the most scientifically inclined among us fall victim to this kind of behavior. We are reluctant to change, we don’t like to have our conventional beliefs challenged, and we are afraid of what we don’t know. We often favor our ideas even if they aren’t the best idea going, and we don’t appreciate someone else trying to steal our thunder. What evolutionary need there is for these traits remains to be speculated. To the author, though, it’s an endearing, if annoying aspect of all of us. Perhaps one day we shall, as a species, overcome these feelings, and embrace the truth more readily, just as our ancestors overcame their fears in order to harness the power of fire. Or maybe that sort of thing will have to be up to the next species that springs from our primitive loins.

Lucy, You Got Some ‘Splainin’ To Do

Tuesday, November 20th, 2007

This is the conclusion of my interview with Dirk Van Tuerenhout, Ph.D., Curator of Anthropology at the Houston Museum of Natural Science. The first half of the interview is titled I Love Lucy.

Dirk, here’s a question from an associate; he mentions that creationists usually say that none of the other hominin species we know about today have anything to do with humans. According to them, fossils like Lucy are not the remains of a related species, let alone a direct human ancestor, but merely “some ape gone extinct”. So how do scientists arrive at the genealogical trees we all know from biology text books?

This is a question that requires an extensive answer. This question has shades of a favorite creationist line to critique/attack on Darwinian evolution. “Darwin says we all came from monkeys. Can you believe that?!”

Here is what we can say to that:

  • Darwin never said we evolved from monkeys.
  • However, we do share with other apes a common ancestor (ultimately also with monkeys, but much more remotely in time).
  • We are as humans also part of the family of Great Apes.

In order to ascertain what links might exist between us and Lucy, we need to define what constitutes a modern human and then see which traits if any we can find with Lucy. Scientists have identified four traits that define a modern human:

  • Walking upright all the time (a.k.a. habitual bipedalism)
  • Making and using tools (complex tools especially)
  • Having a large brain compared to one’s body size
  • Having the ability to communicate (especially complex communication)

Having these traits make us modern humans human. When, however, do we see these traits appear in the fossil record?

Take Lucy, at 3.18 million years ago. She only had one of these traits: she walked upright all the time. In other words, Lucy, like us, was a habitual bipedal creature. That is a significant trait to have and one that separates her from the other apes (living or extinct), because they did not.

Moreover, and equally important: genetic data help us make that distinction more clear cut as well: based on comparing DNA from modern human beings and that of our closest non-human primate relatives (a complicated way of saying: chimps, gorillas and orangutans) we differ very little with these guys. The genetic difference between us and a chimp is about 1% in our DNA. Scientists have calculated that it may have taken about 7 million years for that 1% difference to accumulate over time.

While this number is certainly subject to revision and further study (nothing is black and white in science, there is a continuous questioning of what we know), based on what we know today we can say this:

  • Lucy is a habitual bipedal creature (we know this because of her hips, hip and knee joints) and so are we.
  • Lucy dates to 3.18 million years ago. This postdates the split between our lineage and that of the other Great Apes by about 3 to 4 million years. So in that regard Lucy also belongs on our side of the tracks.

In other words, both her bones and modern DNA data make Lucy a distant relative of ours and not one of the extinct non-human apes.

So how does one put a family tree together?

Initially the family tree was put together based on observed similarities between organisms. Specifically, this led to the development of a family of Hominoidea, of which we are the only member as this time and the family of the Pongidae in which the chimps, gorillas and orangutans are placed. This classification, or taxonomy, goes back to that devised by Linnaeus. He classified based on what he could see.

Nowadays, we classify also based on genetics. That has resulted in the coning of the term hominin, rather than hominid, in which both humans and chimps are placed together (because they are so closely related genetically), with the gorillas and orangutans left in the remaining niche.

In image form, this is what we are talking about:

The traditional view first, based on observed similarities:

traditional

 

 

 

Here chimp, gorilla and orangutans are categorized together, because they look a lot more like each other and not that much like a human.

The more recent classification next, based on genetic relationships:Recent

How do we know that the various hominin species are related and, more importantly, how do we know in what way they are related to each other?

How do we determine the degree of relatedness among extinct hominins? While it is a human trait to want to see everything classified and neatly placed in a pigeon hole, it is not always possible to do this – at least not right away.We always work from the known toward the unknown. At this stage, when a fossil is found, it is compared against known fossils. “Known” here means that we know where they are from, how old they are and where they are placed in the family tree. A new fossil also has a location where it was found and eventually will also have a date assigned to it. What remains (far from simple) is to determine where your fossil fits in. Again you have to work with the known, or in this case: what did you find? If you have a complete skull, it might be much easier to make this determination than if you have found a foot or wrist bone. You compare morphologies and suggest degrees of similarities (and therefore old fashioned taxonomic relationships – see above) to establish a place in the family tree.

Remember, however: science will continue to subject any finding to future insights which might require revisiting and fine-tuning previous conclusions.

When we want to assign a fossil a spot in the genealogical tree, do we have to rely on inferences from bone morphology alone or are there other means of supporting our model?

Given that most fossils (with the exception of H. sapiens and Neanderthalers) do not have extractable DNA in them, we have to rely on morphology, place of discovery and dates to assign a place on the family tree (or family bush as we are calling it today).

What, on the other hand, would we expect to find under the creationists’ hypothesis?

The way in which this is phrased is too kind to creationism: hypothesis belongs in a scientific framework. Creationism or its “scientific” clone, I.D., does not work with hypotheses – no matter how much they would like to disagree with this. In the end, they already have their conclusion: an intelligent creator, or God made everything and here is the evidence for that line of thinking. Creationists/I.D. people are very good at casting doubts on scientist’s interpretations, producing a prodigious amount of materials everywhere to disseminate this perception that scientists do not really know what they are talking about. In reality what they are picking up on is the debate inherent in science on the manner in which evolution has proceeded in the past, not a discussion about the existence of evolution itself. Small detail with important repercussions.

In order to make the point that creationists do not really work with scientific hypotheses but that they prefer to cast aspersions on other people’s thinking to push their agenda, I refer to a point raised earlier: “creationists say Lucy is not an extinct human ancestor but rather an extinct ape.”

By framing the discussion a priori they have – in their mind – already won the battle. They have effectively removed Lucy from our lineage and so more doubt and scorn can be heaped on any arguments to the contrary. One needs to go back to the very crux of the matter and prove that their assertion of where Lucy belongs is wrong in the first place. Having reconstituted a level playing field, then you can proceed by proving that she is indeed an early human ancestor.

As best as I can tell then, a Creationist could not care less about what these fossils might look like and where they belong. In the end, they all see them as evidence of a creation by a Creator to confuse us or to make us marvel at the creation we live in. This is not a form of logic I can follow, but that seems to be their line.

Dirk Van Tuerenhout leverages his time to provide educational opportunities about the Lucy fossil to museum visitors while also teaching at the University of Houston-Clear Lake during the summer. If you are in the Houston area, I encourage you to visit the Houston Museum of Natural Science, and of course, Lucy.
