The double dangerous game of Whiggish What-if? history is on the table in this debate that inexorably invokes hindsight bias, along the lines of “Was Thomas Jefferson a racist because he had slaves?” Adjudicating historical belief and behavior with modern judicial scales is a fool’s errand that carries but one virtue—enlightenment of the past for correcting current misunderstandings. Thus I shall endeavor to enlighten modern thinkers on the perils of misjudging Alfred Russel Wallace as an Intelligent Design creationist, and at the same time reveal the fundamental flaw in both his evolutionary theory and that of this latest incarnation of creationism.

Wallace’s scientific heresy was first delivered in the April, 1869 issue of The Quarterly Review, in which he outlined what he saw as the failure of natural selection to explain the enlarged human brain (compared to apes), as well as the organs of speech, the hand, and the external form of the body:

In the brain of the lowest savages and, as far as we know, of the prehistoric races, we have an organ…little inferior in size and complexity to that of the highest types…. But the mental requirements of the lowest savages, such as the Australians or the Andaman Islanders, are very little above those of many animals. How then was an organ developed far beyond the needs of its possessor? Natural Selection could only have endowed the savage with a brain a little superior to that of an ape, whereas he actually possesses one but very little inferior to that of the average members of our learned societies.

(Please note the language that, were we to judge the man solely by his descriptors for indigenous peoples, would lead us to label Wallace a racist even though he was in his own time what we would today call a progressive liberal.) Continue reading…

Consider the graph above (from the website Calamities of Nature). It shows the relationship between the acceptance of evolution (here defined as “humans beings, as we know them, evolved from earlier species of animals”, a reasonably good metric of true acceptance of evolution) in various countries around the world versus their relative wealth (as measured by GDP adjusted for Purchasing Power Parity). The main trend of countries form a well defined cloud with a reasonable curvilinear fit. At the top are a well-defined cluster of northern and western European nations (plus Japan), with the southern European nations just behind them. Near the bottom are the former Soviet bloc countries of eastern Europe, which still suffer the effects of decades of backward Soviet educational and economic policies. (China, South Korea, and Singapore are not shown, but on other surveys, they all rate high on the acceptance of evolution scale. so they would plot high on the ordinate or Y axis, no matter what their GDP).

The same relationship could be shown if you consider any of the recent surveys that measure science literacy on an international scale. The northern and western European nations (especially Germany and the Scandinavian countries plus Iceland) nearly always come out near the top, along with Japan, Singapore, South Korea, and sometimes China. The exact order differs from survey to survey, but they only shuffle within the top 10 or top 15. In other words, the acceptance of evolution in these countries is a very strong predictor of overall science literacy.

Now look at the position of the U.S. It is a striking outlier on the graph shown here, because its low rate of acceptance of evolution relative to its national wealth (and the same would be true if you plotted it against the money spent on education per student). It falls down near the bottom of the curve on evolution acceptance along with Islamic nations like Turkey, which spend much less per student. What is this telling us?

I have written frequently in these blogposts about the numerous forms of denial of science and reality that are out there, from global warming denialism, to AIDS denialism, anti-vaxxers, and creationism. They all have a lot in common, from their insular exclusionary attitude that refuses to accept evidence that doesn’t fit their world view, to the various strategies they use to reduce cognitive dissonance and fight against reality, all borrowed from the Holocaust deniers. These include: quoting out of context (“quote-mining”) to dishonestly suggest that the quoted person agrees with them, cherry-picking data to show the exact opposite of what the data really show, making phony lists of “experts” who agree with them, picking on the small differences within the scientific community as evidence that the “science is not settled”, picking on one small factoid (usually misinterpreted and out of context) as evidence that the whole of science is false, and so on. Usually, these obvious strategies to deny an overwhelming body of evidence are so transparently self-delusional that we can laugh at them.

But then I ran into something that staggered even my sense of how low these people can go. We are all familiar with how creationists use ad hoc explanations and special pleading to rescue the absurdities of their world view, from trying to cram all of the animals into Noah’s ark and dismissing the huge numbers problem through their non-biological concept of “created kinds”, to doing all sorts of violence to the geologic record to justify the Noah’s flood story, to even insisting that men have one less rib than do women (the last one is easy to check, but they don’t). As I have discussed in several previous posts, the more extreme Biblical literalists also believe in a flat earth and reject the heliocentric solar system. But I was flabbergasted to read of a whole group of extreme creationists who deny that dinosaurs existed! Usually, the creationists not only come to terms with the evidence of dinosaurs, but many have even tried to co-opt their popularity with kids under 10 by making them a prominent part of their propaganda (as does Ken Ham of the “Answers in Genesis” ministry and the “Creation Museum” in Petersburg, Kentucky). With something as widely accepted and exciting and popular as dinosaurs, which anyone can see for themselves in their local museum, how could any person in the 21st century argue they are not real?

People love to touch old objects and feel a connection to the past, whether it be the Wailing Wall in Jerusalem, ancient ruins in China or India or Egypt or Europe, pieces of fossil bone on display in a museum, or the oldest objects known, the 4.6 billion-year-old meteorites. Each time I travel to do research in historic old museum collections, it feels a bit like time travel. In my field, the original specimens first described by the founders of my profession, 19th-century paleontologists like Edward Drinker Cope, O.C. Marsh, and Joseph Leidy, are still essential parts of our research. We must examine these “type specimens” to determine whether fossil species these people named and described over 100 years ago are still valid today, when we have much better and more complete and abundant specimens. When I visit the Academy of Natural Sciences in Philadelphia, I can examine type specimens first named by Leidy in the 1850s. At Yale, nearly every specimen I looked at was first studied by Marsh in the 1870s and 1880s. At the American Museum of Natural History in New York, I worked not only on fossils first studied by Cope in the 1870s and 1880s, but the Osborn Research Library in the Department of Paleontology even has Cope’s  geology pick where any visiting scientist can touch it, or one can sit down at Cope’s original desk. Cope’s skull (donated to science, along with his entire skeleton) has floated around various museums, and many paleontologists have handled it as well (with lots of jokes about the odd situation).

Vertebrate paleontology is also such a small profession with so few practitioners in its mere 150 years of existence that we’re all connected by our graduate advisors to just a handful of men who founded the profession over a century ago. When I was a student, I shook the hand of Ned Colbert, who was Henry Fairfield Osborn’s assistant in the 1920s, and Osborn bragged that he had shaken both Darwin’s and Huxley’s hand when he did post-graduate study in Europe. So I’m only 3 degrees of separation from Darwin himself. (I also have a friend who was in the cast of the original “Footloose”, so I’m 2 degrees from Kevin Bacon).

When I visited the American Museum this fall to continue my research on fossil peccaries or javelinas (American pig-like creatures only distantly related to Old World pigs), I was keeping a close watch for one specimen in particular. Everyone who has fought in the evolution-creation wars has heard of it, and I wanted to finally see and touch the specimen for myself. It is the tooth that caused a sensation in the 1920s, and has since become something that creationists harp on excessively, even though their version of the story is full of lies and myths. It is the tooth known as Hesperopithecus haroldcooki (“Harold Cook’s western ape”). Continue reading…

In my October 26 post, I discussed the efforts of creationists to run “stealth” field trips at the annual meeting of the Geological Society of America in Denver in 2010. There were no such attempts at the Minneapolis meeting on Oct. 9-12 that I attended last month, but instead they did something  they often do at professional meetings like GSA: stealth abstracts. I saw a bunch of posters from people at Cedarville University, a fundamentalist Baptist institution in Ohio. These posters pretended to be legitimate research about the deposition of the Permian dune sand unit, the Coconino Sandstone. This famous unit in the upper part of the Grand Canyon is clearly formed in wind-blown dunes and not a deposit of  Noah’s flood (or of any kind of fluid other than wind). Since their dogma insists that the entire sequence in the Grand Canyon is laid down by Noah’s flood, the Coconino is a particular problem for them, and they focus their attention on it. (See the evidence and discussion in Chapter 3 in my book Evolution).

The posters were stuck in a session with a bunch of other posters presenting more conventional research into sandstones, and they looked professional enough that no one would notice. Other than their Cedarville affiliation, there was no clue about their creationist agenda, and there was no mention at the end of the abstract, or the conclusions section of the poster, that they were shilling for anti-scientific creationist views. I repeatedly walked past both posters during the day they were up, but never once found the authors defending it, even during the time that the GSA demands that “Authors will be present”.

The Geological Society of America (GSA) is one of the largest organizations of geologists in the world (over 24,000 members). It holds not only an annual meeting every fall in a different city, but also five regional meetings around the U.S. regions (Northeast, Southeast, Midwest, Rocky Mountains, and Cordilleran) throughout the year. Although 97 different countries contribute members, it is composed mostly of U.S., Canadian, and some Central American geologists. The GSA focuses on the cutting-edge and pure research aspects of geology, performed mostly by academics and government geologists. Thus, it is very different from meetings of petroleum geologists or mining geologists or engineering geologists, who tend to be employed in for-profit enterprises and focus on purely practical local problems. The annual GSA meeting routinely draws 6000 or more people for a four-day session, so there are over 2000 talks and posters in at least 30 different sessions with talks every 15 minutes in at least 30 different rooms scattered around some  huge convention center. There SO much to see and hear for a broadly trained and wide-ranging geologist/ paleontologist like myself that I can’t even catch a fraction of what I want to see and hear. For me, it is crucial to make the annual meeting each year to keep up with the latest developments, as well as see old friends that I see only at the meetings, and also to keep up with my geology textbooks and my other books sold in the gigantic exhibits area. I attended my first meeting in 1978 in Toronto, and I have not missed a national GSA since then. I just returned from this fall’s meeting in Minneapolis October 9-12, which was my 33rd in a row.

Most of the time when I attend the meetings, there are plenty of controversial topics and great debates going on within the geological community, so the profession does not suppress unorthodox opinions or play political games. This is the way it should be in any genuine scientific discipline. I’ve seen amazingly confrontational knock-down-drag-out sessions about particularly hotly debated ideas, but always conducted in a spirit of honest scientific exchange and always hewing to rules of science and naturalism. To get on the meeting program, scientists must propose to organize sessions around particular themes, along with field trips to geologically interesting sites within driving distance of the convention city, and the GSA host committee reads and approves these proposals. But every once in a while, I see a poster title and abstract with something suspicious about it. When I check the authors, they turn out to be Young-Earth Creationists (YEC) who claim the earth is only 6000 years old and all of geology can be explained by Noah’s flood. When I visit the poster session, it’s usually mobbed by real geologists giving the YECs a real grilling, even though the poster is ostensibly about some reasonable geologic topic, like polystrate trees in Yellowstone, and there is no overt mention of Noah’s flood in the poster. But the 2010 meeting last year in Denver took the cake: there was a whole field trip run by YECs who did not identify their agenda, and pretended that they were doing conventional geology—until you read between the lines.

I’ve posted frequently (see my July 24 post) on the religious kooks who insist that Galileo and Copernicus and all later astronomers were wrong  and that the earth, not the sun, is the center of the solar system. They base this weird notion on their own version of biblical literalism, since there are many passages in the Bible (e.g., Isaiah 11: 12, 40:22, 44:24; Joshua 10:12-14) which clearly present a geocentric world viewpoint (as was widely held in almost all ancient cultures and not overturned until the 1500s). Many are actually renegade Catholics who not only insist that Galileo was wrong and that the Church was right, but what the Inquisition did to Galileo was justified. Naturally, the Catholic Church is not too happy about these revisionists, since it has long come to terms with Galileo and scientific reality, and even apologized for its treatment of him. They don’t spend a lot of unnecessary time trying to repudiate or excommunicate these renegades who want to drag us back to the 14th century. I guess the Church is busy with other problems….

Recently, the Los Angeles Times ran an article on the latest version of the Catholic geocentrist movement. The article says:

“I have no idea who these people are,” said Brother Guy Consolmagno, curator of meteorites and spokesman for the Vatican Observatory. “Are they sincere, or is this a clever bit of theater?”

Those promoting geocentrism argue that heliocentrism, or the centuries-old consensus among scientists that Earth revolves around the sun, is a conspiracy to squelch the church’s influence.

“Heliocentrism becomes dangerous if it is being propped up as the true system when, in fact, it is a false system,” said Robert Sungenis, leader of a budding movement to get scientists to reconsider. “False information leads to false ideas, and false ideas lead to illicit and immoral actions — thus the state of the world today.… Prior to Galileo, the church was in full command of the world, and governments and academia were subservient to her.”

Two weeks ago, I did a whirlwind 39-hour trip to the Bay Area to give two different talks (one to the Bay Area Skeptics in their Chilean restaurant hangout) and also to study some fossils at the University of California Museum of Paleontology for my ongoing peccary research. It was great hanging out in the People’s Republic of Berkeley again, enjoying the incredible ambiance of Telegraph Avenue, the colorful characters on Shattuck, the amazing array of ethnic restaurants block after block, the classic “woo” of all the Eastern mystic temples, and palmistry and naturopathy and New Age shops, the chirping cross-walk warnings, and PC reminders everywhere—and seeing all the homeless people rooting through the garbage. It’s like a time warp for me, reminding me of when I first visited as a student in the 1970s—except that the hippies are still here, a bit older and grayer, but now becoming psychedelic relics. Many parts of town still have the spirit of the “Summer of Love” while others are punk or goth or hip-hop. It’s eye-opening to see the sign at the city limits proclaiming Berkeley a “nuke-free zone”(not that it matters, since there are no nuclear reactors or military bases there, and the nuclear physics is done out at Lawrence-Livermore lab).  Every time I go to one these college towns where the Sixties never ended and lots of hippies have gone to live (not only Berkeley, but also Eugene, Boulder, and Santa Cruz), I have an incredible rush of memories of that time, and the dreams my generation fought for. As a Boomer myself and child of the Sixties, it’s great to see that not every aspect of it has been forgotten or dismissed (especially not the music, of course, which has remarkable resilience).

The terrifying fortress headquarters of the "Evil Empire"

After finishing my research on the fossils, I  had a bit of spare time, so on invitation from Steve Newton and Josh Rosenau (who attended my Bay Area Skeptics talk), I decided to pay a visit to another cultural landmark: the headquarters of the National Center for Science Education. This is the chief non-profit organization in the U.S. that helps local school boards and scientists and teachers when creationism threatens their classrooms. If you read the creationists’ literature and the posts on the ID creationist Discovery Institute’s (DI) website, the NCSE is this monstrous organization which exerts mind-control over every scientist in the country, and forces them to robotically chant “I accept evolution.” According to the creationists, the NCSE is pure evil, suppressing the creationism message with its enormous staff and budget and power over all of U.S. science. In Ben Stein’s crappy little creationist propaganda film Expelled, Ben pays a visit to the gleaming  headquarters of the Discovery Institute in Seattle, which occupies a vast amount of floor space in a brand-new office building downtown, and has a huge staff. Over and over again the DI staffers complain about how they scientific establishment is against them, and how the NCSE has so much more power, money, and influence than they do.

The continuing problem of creationists and their efforts to hamper science education and research in this country never seems to abate. Some people throw up their hands in resignation and say, “We can never change their minds, so let’s just ignore them.” As I pointed out in my book Evolution: What the Fossils Say and Why it Matters, we cannot afford to ignore the creationist threat to science. Not only do they undermine the proper teaching of biology in our schools, but they have made no secret that their goal is to suppress any science that is not consistent with their literalistic view of the Bible. Good bye, astronomy and cosmology. Good bye, physical anthropology and human paleontology. Good bye, geology (and forget finding oil or coal or gas ever again). Good bye molecular biology, and its evidence for evolution. And forget all the benefits that these sciences provide us, or the richer perspective on life that we gain by understanding our true place in the universe, rather than the version handed down by some Bronze Age shepherds.

But a bigger problem is the fact that in some cases, denial of evolution is dangerous or even deadly. Evolution keeps happening all the time, whether creationists want to believe it or not. Yet if we deny the fact that evolution is happening in viruses and bacteria and in other pathogens and pests, it only makes the problem worse when they evolve resistance to whatever we throw at them. If creationists ran the labs that produce these protective chemicals, do you think we would have a chance when the next deadly pest hits us? Continue reading…

Whenever I read about the conventions held by creationists, it is always staggering to see so much ignorance of science and scholarship on display. If you read through one of their programs or peruse the abstracts, your mind is boggled at the bizarre thinking and intellectual contortions these people must attempt, from weird ideas of how to fit all living thing into Noah’s ark to odd explanations of where the flood waters came from and where they went, to even weirder ideas of why the universe appears to be 13.7 billion years old (but is only really 6000 years old), or why radiometric dating doesn’t work or how to explain the complex geologic history of the earth with Bronze Age myths of superstitious shepherds. One paper after another is replete with special pleading, ad hoc and supernatural “explanations”, none of which would pass muster in even an introductory physics or geology class. As I discussed in my book Evolution: What the Fossils Say and Why It Matters, these people are profoundly ignorant of real science and proud of it, because their faith comes first. Sadly, they have about 40% or so of the American public believing their anti-scientific view of the world.

No matter how weird their ideas seem to the outsider, we can at least understand their motivation. To the fundamentalist creationist, a literal interpretation of their version of the Bible is a life-or-death, salvation-or-damnation matter, which is why they invest so much energy confusing people with their distorted ideas about sciences like evolution, geology, anthropology, and astronomy.  If one truly believes that Darwinism will lead you to hell’s door, we can see what makes them think this way, no matter how wrong it seems to us. But, as we smugly assert, they are just fringe religious fanatics, and they are only fighting the most recent scientific battle over evolution (that still rages 152 years later). Surely, the great victories of science, such as the Copernican system of astronomy and the Einsteinian revolution in physics, are no longer disputed and even religious fanatics accept them. Right?
