So I was on a panel discussion about micro vs. macroevolution…

Several weeks back I get an email from Phil Calderone, a member of one of the local atheist/agnostic/freethought groups (I.E.A.A.), asking if I would like to act as a fill in on a (then) upcoming “believers vs. non-believers” panel discussion on the subject of micro vs. macroevolution. Apparently, one of the persons originally invited was not going to be able to participate and he needed a fill in and was pointed towards me by Dr. Brad Hughes, who many years ago I had helped (along with others) prepare for a debate with “Dr.” Kent Hovind.

After some trepidation—due to having never done any public speaking before—I agreed to participate as long as it was understood that I was unlettered and neither a paleontologist or biologist but rather a mere amateur naturalist who has had a bit of experience in the creation/evolution debate. 

The format of the discussion was meant to be a relatively informal back and forth between four people with two on each side. One the “believers” side there was a gentleman named Kelly Clemensen, of something called the Areopagus Project, and Dr. Paul Giem of Loma Linda University (see also Giem’s web page here). On the non-believers side was myself and Phil Calderone who was to moderate but had to fill in the second non-believers chair for another person who couldn’t make it.

I will not go into any more description of the event as it was recorded on video and you can watch the proceedings for yourself below. However, truth and honesty before all I will be addressing at least two places where I know I screwed up in the discussion below the video.

Please feel free to point out any other mistakes I made, or address the many points made by the creationists that went unaddressed by either Phil or me during the discussion. I know there are whole bunches of things that our opponents said that was missed or deserved more in depth dissection.

Now that you have, hopefully, watched the video there are two places that I realized I messed up pretty much right after the debate. One was minor memory failure, misattribution about punctuated equilibrium. The other was a more significant—at least in my opinion—point were I brought up a group of fossil organisms that was really something of a red-herring—though I committed the fallacy out of partial ignorance—and should have known better from other statements I myself had made at other points in the same discussion!

Creationism Nit: Archaeoraptor?

So the other day I found myself near one of the local Bible book stores and since I had the time wandered in to see what creationist fare they might have in their apologetics section. As it turned out not a lot, however in the homeschooling section they did have this little tome titled, Exploring the world of biology: From mushrooms to complex life forms (2009) by a John Hudson Tiner and published by Master Books (which as far as I know is still a subsidiary of the Institute for Creation Research):


I am not sure why Mr. Tiner—who is apparently a math teacher—chose to start with mushrooms in his “exploration” but even leaving out simpler organisms makes his exploration a tall order when he only has 160 pages to work with.

Regardless, I am not here to critique the entire book, or even the section from which I have drawn my nit (I couldn’t do so in good faith anyway, as I only flipped through the book and took a couple quick photos). I am only here for the nit, nit, nit!

And the nit is this from page 133:

archaeoraptorHere we have a black and white photo of a fossil which is labeled Archaeoraptor liaoningensis.

Huh, yeah, it is just that the problem is the picture is not of that notorious fraudulent fossil. See for yourself; compare the picture above with following illustration of the actual Archaeoraptor: 

(Pickrell 2015)

You don’t have to have a degree in comparative anatomy to tell these two specimens apart.

What Tines has done is publish what is clearly a cropped photograph of the Berlin specimen of Archaeopteryx siemensii perhaps the single more famous and recognizable fossil in the worldand mistakenly labeled it as Archaeoraptor.

So, yeah, “oops!” Mr. Tines may want to familiarize himself with Archaeopteryx before he opines on the state of the fossil evidence for the evolution of birds from other dinosaurs (let alone starts writing books that might fall into the hands of impressionable children).

Secular Museum Blunder

To demonstrate once again that I am an equal opportunity critic, here is a nit I have to pick with a secular museum, namely the Riverside Metropolitan Museum located in downtown Riverside, CA. It is a small museum and most of its limited public floorspace is taken up by displays dealing with Native American culture and artifacts. However it also has a number of displays on natural history, primarily that of the mountains & deserts in Riverside County. It is near some of these displays I found the following stuck to a wall:


And here is the lone label seen in the bottom right-hand corner:


It reads, “Baron Cuvier’s Pterodactyl“, apparently a reference to the fact that it was the “father of paleontology” Georges Cuvier who dubbed one of the earliest discovered pterosaur fossils “Ptéro-Dactyle”.

Yeah, the problem is though the cast of the fossil accompanying the label is very clearly not of the genus Pterodactylus named by Cuvier. Rather it is a cast of a RhamphorhynchusHere for comparison is the holotype specimen of Pterodactylus:


The red arrow points to Pterodactylus’ rather diminutive tail, which stands in rather stark contrast to Rhamphorhynchus’ long kite-like tail which ends in a diamond shaped vane (see above). 

Amusingly this is not the first time that these two genera have been confused. Apparently Rhamphorhynchus was originally misidentified as a species of Pterodactylus but after a few rounds of reclassification finally ended up as its own genus by the hand of Richard Owen 1861.

So a wag of my finger to the Riverside Metropolitan Museum; you need to fact check your displays.

Consilience and whale evolution

Way, waaay back in December of 2005 (ye gods has been ten years already?!) I wrote a Feedback response on the Talk Origins Archive to a question about the vestigial pelvic bones found in modern whales. In this case the questioner did not believe them to be truly vestigial, no doubt due to holding erroneous beliefs regarding the subject. In my response I of course took the time to correct their faulty views, however I also used the opportunity to talk about the concept of consilience wherein multiple independent lines of evidence converge on a single explanation, giving us greatly increased confidence that those explanations (hypothesis/theories) are likely to be accurate reflections of reality, i.e. “true”. 

I have now and again thought of going back and using that post as a spring-board for a more detailed examination of this subject and who knows, I may still do so someday. In the meantime however, here is a great video from Stated Clearly that I ran across on Facebook recently that uses the same topic—whales—to essentially do the same thing I did all those years ago; make a point about the consilience of evidence pointing to a pretty definite conclusion with regards to not just the ancestry of cetaceans but the evolution of life in general. Better they include more details than I did and it has animations.

I miss answering the feedback question on Talk Origins…

Some Xmas gifts plus

Just wanted to share a couple fun Christmas presents I got this year and a couple of gifts I got earlier in the year that I have been meaning to post some pictures of but had not yet got round to doing so.

The first is an amusing caricature of yours truly, drawn by Gabriel Corral (who was, until recently, one of my co-workers):

A caricature of me riding a sauropod while waiving a Darwin-fish flag. The caption reads: "Not scientifically accurate".

He drew caricatures of each of us who work, or worked, at AFS Printing as Christmas gifts.

Next is a painting by my sister, Kindra Pizarro, of a skeleton tree:

Very cool (be sure to check out her Etsy store: Voodoo Kitty Handmade Oddities).

Finally a couple of neat dinosaur statuettes given to me by my friends Don and Gaynell Frack, I think for my last birthday (or maybe even last Christmas, can’t recall):

A Stegosaurus statuette.

A Stegosaurus statuette.


A Triceratops statuette.

Apparently they bought them, for a very reasonable price, at an art sale put on by a Buddhist temple. Both are very cool, though I think I like the Triceratops best. The only problem is my ever finding a place to display them where the cats won’t be able to destroy them (first world problems).

So that’s it for now, thank you so much Gabriel, Kindra, Don and Gaynell for the thought and the gifts!

Memories of Peking Man at the American Museum of Natural History

Jon and I outside The Academy of Natural Sciences in Philadelphia of Drexel University, PA (photo by Don Frack).

While looking through some old photographs, for something else I am working on, I came across some snap shots I took back in 1998 when my friend Don Frack and myself flew back to the East coast to attend the DinoFest 98 symposium (a combination dinosaur fossil exhibition and gathering of dinosaur paleontologists) in Philadelphia, PA.

We figured that to make going really worth our while (and our money), we would make a couple of side trips. We planned to arrive a couple days early, rent a car and drive up to New York for a day and go to the American Museum of Natural History (we were joined on this leg of our journey by our friend Jonathan Woolf who we knew from back in the CompuServe forum CvE debates). We would then

return to Philadelphia and attend the three day symposium, after which Don and I would drive down to Washington D.C., go to the Smithsonian National Museum of Natural History and fly home from there.

It was at once a fun, fascinating and frustrating trip, which I won’t get too much into now. Let’s just say the both of us a life-long Californians experienced a combination of a bit of culture and geography shock.

Anyway, since we were going to go to the American Museum, Don thought he might contact a couple of the scientists who worked there to see if we could go behind the scenes and get a closer look at some of the material in their collection. In this case material that is of particular interest to those of us involved in the creation/evolution debate, namely their casts of the original “Peking Man” (a.k.a. Sinanthropus pekinensis but now recognized as Homo erectus) material. The fossils represented a number of individual H. erectus‘, unearthed in China at a site known as Zhoukoudian (or Choukoutien) near Beijing in the late 1920’s and early 30’s.
