Ken Ham, who runs a tax-exempt nonprofit and has received various tax breaks and subsidies from the city and the state, writes,

“The Nation’s T. Rex” will be a centerpiece for the Smithsonian–a museum funded by our tax dollars. In reality, then, the government is imposing the religion of evolution and millions of years on children visiting the Smithsonian, while also claiming a supposed separation of church and state! Our tax dollars are funding the religion of naturalism (atheism) and its evolutionary story to be exhibited in the Smithsonian in the nation’s capital!

I occasionally get books for review unsolicited, and many of them are not worth noticing. However, Kostas Kampourakis' Understanding Evolution is a wonderful resource for students of all kinds, including biology students.


Once again, desperately dissing Avida

| 56 Comments (new)

One of the characteristics of a pseudoscience is repeating discredited arguments as though they were new. And sure enough, once again an Intelligent Design Creationist is flailing around trying to discredit research in digital evolutionary models that shows that structures displaying IDC’s central concept, irreducible complexity, are evolvable via Darwinian processes. I have previously looked at earlier attempts to discredit that research; see here and here for examples.

Now it’s happening again. This month, Winston Ewert, affiliated (according to the paper) with the Discovery Institute’s Biologic Institute (though he doesn’t appear on their published list of personnel), published a review and critique of several computer models of evolution in the DI’s captive journal Bio-Complexity. Ewert was a graduate student of Robert Marks at Baylor, where he was associated with Marks’ and Dembski’s Evolutionary Bioinformatics Lab. He now has a Ph.D. from Baylor, the first in Baylor’s combined electrical engineering and computer science graduate program.

In his critique Ewert looks at five programs: Avida, Tom Schneider’s Ev, Dave Thomas’s Steiner tree GA, Suzanne Sadedin’s geometric model, and Adrian Thompson’s “digital ears”, a program realized in field programmable gate arrays. Here I will analyze Ewert’s critique of Avida; I am less familiar with the other models Ewert discusses. However, given the errors I find in his discussion of Avida, I am very dubious with respect to his analysis of the other programs. If he does so badly with something I know pretty well, why should I trust his judgement in areas I don’t know so well?

After repeating an introduction to Avida that I wrote some years ago, I will follow (roughly) Ewert’s analysis, in which he first describes all five programs and then criticizes them. Hence, I’ll look at Ewert’s description of Avida, and in particular note several errors in it, and then I’ll evaluate his criticisms. I find that his description is faulty and his critique ill-founded.

Branta canadensis

Branta canadensis – Canada goose on nest, Walden Ponds, Boulder, Colorado, 2014. The nest is on a small island in the middle of a pond. The goose sat on her (?) nest for most of the hour or so that we hung around. Then she got up, apparently cleaned the nest, and took off for a tryst or something with her boyfriend. We could see no sign of eggs or babies, but we thought we heard a high-pitched chirping coming from the nest when the parents were gone. The geese came back a little while later, and one of them immediately sat down on the nest. We plan to check on our newfound friends every week or so and will report back if there is anything to report.

It’s a 3-part series with Neil Shubin, the paleontologist who discovered Tiktaalik. The series begins tomorrow, Wednesday, April 9, at 10 p.m. Eastern Daylight Time. You can see a preview here.

Rocky Mountain PBS says about the series

Anatomist and paleontologist Neil Shubin sees evidence of our ancient past in our anatomy and in our DNA. Join him as he journeys to meet our ancient animal ancestors, while revealing the impact those animals have had on our bodies

and they have an interactive webpage here.

The second and third episodes are called “Your Inner Reptile” and “Your Inner Monkey.”

Update, April 9: An AP release yesterday afternoon notes that PBS will also premiere a 3-part Nova series tonight. Tonight’s episode: “Inside Animal Minds.” These 2 series, along with Nature, exemplify PBS’s new “Think Wednesday” schedule, which AP characterizes as “a three-hour prime-time block of nature, science and technology programs” anchored by Nature and Nova.

My, how time flies.

PZ reminds us that today is the 10th anniversary of Paul Nelson’s promise to deliver an operational definition of “ontogenetic depth.” Nelson said it would be forthcoming “tomorrow.” When I was about four years old it struck me that tomorrow never comes.

And I can’t resist re-publishing this:

Concerning Richard B. Hoppe and his requests for Paul Nelson to provide support for his Intelligent Design claims about Ontogenetic Depth:

Paul Nelson’s “depth” tales sounded tall.
Richard Hoppe thought, “it’s past time to call
Nelson’s ontogenetic-
clad apologetic.”
Quoth Richard, “So where’s the beef, Paul?”

I doubt that he’ll find satisfaction,
nor even a lucid reaction.
Behind the smoke screen
there’s an ID machine
building weapons of media distraction.

A meal of Intelligent Design
when served with the fruit of divine
is lacking in beef,
which supports my belief
that it’s tripe marinating in whine.

Yeah, yeah, I know: Schizophrenia is a specific medical diagnosis, and it does not mean holding two views at the same time. But its etymology does imply something like split mind, and I cannot think of a better way to describe this:

The Creation “Museum” has put on display the Allosaurus fossil that we reported on here. And they are tickled pink. Their house geologist, Andrew Snelling, who used to do real geology (or his doppelgänger did) said of their Allosaurus,

Geranium richardsonii

Geranium richardsonii – wild geranium, Pearl Lake, Colorado.

Since everyone is all het up about Noah, I thought I would resurrect (sorry) a narrative I wrote 15 years ago for my book on science and religion. The “Friedman” I cite is Richard Elliott Friedman, author of Who Wrote the Bible? I used the section primarily to explain why scholars are convinced that the Hebrew Bible is a composite of two different but related methodologies (the documentary hypothesis), but it also shows the utter incoherence of the Bible when read as a literal history. The excerpt may be found below the fold.


Well, AiG’s Ken Ham has seen the movie “Noah” starring Russell Crowe, and boy, is he steamed!

Friends, I just arrived home after seeing the Hollywood (Paramount) movie NOAH tonight. It is MUCH much worse than I thought it would be. Much worse.

The Director of the movie, Darren Aronofsky has been quoted in the media as saying NOAH is ‘the least biblical biblical film ever made’, I agree wholeheartedly with him.

I am disgusted. I am going to come right out and say it-it is disgusting and evil-paganism! Do you really want your family to see a pagan movie the has Noah as some psychopath who says if his daughter-in-law’s baby is a girl, he will kill it as soon as it’s born. And then when two girls are born, bloodstained Noah (the man the Bible calls righteous Noah-Genesis 7:1), brings a knife down to one of the baby’s heads to kill it and at the last minute doesn’t do it-and then a bit later says he failed because he didn’t kill the babies. How can we recommend this movie and then speak against abortion! Psychopathic Noah sees humans as a blight on the planet and wants to rid the world of people.

I feel dirty-as if I have to somehow wash the evil off me.

Aythya americana

Aythya americana – redhead, Walden Ponds, Boulder, Colorado, 2014. A stray widgeon insisted on getting into the picture. (The person with the biggest binoculars told me that they were cinnamon teals, but that does not look right. Someone with a good pattern-recognition system please correct me if necessary.)

Cygnus columbianus

Cygnus columbianus – tundra swan, Walden Ponds, Boulder, Colorado, March, 2014. A single swan, presumably the same one, has been showing up here for the last few years. I looked for the people with the biggest binoculars and the longest focal-length camera lenses and asked how come there was only one? I got several answers, all of which begged the question why the bird is not in a flock: (1) They mate for life, and maybe this one lost its mate. (2) They mate for life, but maybe they don’t always hang around together. (3) Maybe this one is a juvenile, not old enough to have a mate.

I finally watched a tape of the first installment of the new “Cosmos” series the other day. I thought it was a bit overdone and maybe a little slow, and I thought the cartoons were ghastly. (Also, there were gobs of commercials; why oh why is this series not showing on PBS?) Never once did I imagine that anyone would accuse such a completely innocuous television program of being propaganda for materialism. Yet according to a Salon article by Andrew Leonard, the far right has accused the program of being precisely that. Ironic that is showing on the Fox network!

I have not looked at the primary sources, so I will have to take Leonard’s word for it, but they may be right about Giordano Bruno. The conventional wisdom is that Bruno was burned for supporting the heliocentric theory, but the historian Alberto Martinez, in his book Science Secrets, thinks that it may as well have been because of his theological views: doubting that Jesus was born of a virgin and denying that he was actually God. Bruno was, nevertheless, an early and vigorous supporter of the Copernican theory, and only an idiot or a conspiracy theorist (but I repeat myself) would think that Bruno was introduced into the program for nefarious reasons.

Acknowledgment. Thanks to Walter Plywaski for showing me the Salon article.

Paabo_2014_Neanderthal_Man_cover.jpgPeople have been sending me this, so I might as well blog it. In February 2014, Svante Pääbo, who led the Neanderthal genome project, published a popular book on the sequencing of the Neanderthal genome, and reactions to it.

I haven’t yet read the book, although I’m sure it’s great, based on talks I have seen by Pääbo. However, there is one passage that PT readers may find particularly interesting:

Svante Pääbo (2014). Neanderthal Man: In Search of Lost Genomes. Basic Books; First Edition (February 11, 2014), 288 pages[…]e/B00GJ9XR7O

p. 221:

There were many others who were interested in the Neanderthal genome – perhaps most surprisingly, some fundamentalist Christians in the United States. A few months after our paper appeared, I met Nicholas J. Matzke, a doctoral candidate at the Center for Theoretical Evolutionary Genomics at UC Berkeley. Unbeknownst to me and the other authors, our paper had apparently caused quite a flurry of discussion in the creationist community. Nick explained to me that creationists come in two varieties. First, there are “young-earth creationists,” who believe that the earth, the heavens, and all life were created by direct acts of God sometime between 5,700 and 10,000 years ago. They tend to consider Neanderthals as “fully human,” sometimes saying they were another, now extinct “race” that was scattered after the fall of the Tower of Babel. As a consequence, young-earth creationists had no problem with our finding that Neanderthals and modern humans had mixed. Then there are “old-earth creationists,” who accept that the earth is old but reject evolution by natural, nondivine means. One major old-earth ministry is “Reasons to Believe,” headed by a Hugh Ross. He believes that modern humans were specially created around 50,000 years ago and that Neanderthals weren’t humans, but animals. Ross and other old-earth creationists didn’t like the finding that Neanderthals and modern humans had mixed. Nick sent me a transcript from a radio show in which he [meaning Hugh Ross] commented on our work, saying interbreeding was predictable “because the story of Genesis is early humanity getting into exceptionally wicked behavior practices,” and that God may have had to “forcibly scatter humanity over the face of the Earth” to stop this kind of interbreeding, which he compared to “animal bestiality.”

Clearly our paper was reaching a broader audience than we had ever imagined.

Imagine that. anecdotal-oops.jpg

The above is the copy I got in an email.

Somebody spilled the beans, alas, and the corrected version with “antidote” has been posted.

Too late, we’ve gotten our belly laugh! Nyah Nyah, Discovery Institute, no memory hole is big enough to make this laughable faux pas go away.

I occasionally receive a request to print or post a photograph that has appeared on Panda’s Thumb, but this one takes the cake: A magazine called Creation Illustrated, which bills itself as “The Christian answer to National Geographic,” requested permission to publish this photograph


in its magazine. Fat chance!

Their e-mail was datelined, “URGENT - Matt Young’s photo of Table Mountain needed.” Needed, eh? I am afraid I was not very kind to them:

Thank you; I am glad you liked my photograph. Unfortunately, under no conditions will I allow this photograph (or any other to which I own the copyright) to be published in any creationist publication. So my answer is, “No.” Did you not notice that the website, Panda’s Thumb, where the photograph was published, is devoted to scientific reality, that is, evolutionary science? “Christian answer to National Geographic,” indeed!

Until now, I was blissfully unaware that National Geographic needed an answer of any kind.
