Irreducible complexity reduced

YouTuber QualiaSoup has produced a very nice, concise, refutation of the “irreducible complexity” argument used by intelligent design creationists against evolution; check it out:

More from Inside Nature’s Giants

Two more episodes from the excellent television series Inside Natures Giants are now available for viewing on YouTube. As I wrote in a previous post, this is a fascinating zoology program wherein the bodies of various large animals are dissected to demonstrate the details of their anatomy. This is combined with discussions of the living animals and their natural history with occasional incites from Richard Dawkins about evolutionary biology.

First of the newly available episodes is a two for one in which both a lion and tiger are examined, contrasted and compared. Here is part one of four:

A play list for the rest of the parts can be found here.

In my previous posting on this series I wished for them to focus an episode on something like a giant squid so as to show something on invertebrate anatomy and my wish has come true. Here is part one of five:

I couldn’t find a play list for this episode so here are individual links to the different segments: part 2, part 3, part 4, and part 5.

As before I really cannot speak more highly of this program. It is fascinating television for anyone with even the slightest curiosity about the natural world and a absolute must see for anyone interested in biology, zoology and evolution.

Gush, gush, gush!

[Thanks to P.Z. (squee) Myers over at Pharyngula for the heads up on the squid episode and to the WhyEvolutionisTrue YouTube channel for hosting the videos!]

Rush Limbaugh’s clueless rant about evolution

This last week I had the misfortune to hear Rush Limbaugh flapping his yap attempting to defend Christine O’Donnell’s ignorant comments about evolution. Unsurprisingly his comment were a grab bag of typical creationist nonsense. Here is the audio of the beginning of his diatribe:

Vodpod videos no longer available.

Paraphrasing from the audio: “If humans evolved from monkeys then why are there still monkeys?”

This is logically exactly the same thing as asking “if my cousin and I are actually related, then why does my cousin still exist?”

Inside Natures Giants

I recently stumbled upon (on YouTube) a BAFTA award winning British TV series titled Inside Natures Giants and I’ve fallen in love. What we have here is a television show in which various large animals, all vertebrates so far, are dissected on camera (and often in front of a live audience of students)  by a team of biologists in order to show the details of their anatomy while presenting elements of their physiology, natural history and evolution (including commentary by evolutionary biologist Richard Dawkins).

So far the show has dissected an Asian elephant, a fin whale, a Nile crocodile, a Rothschild giraffe, a great white shark, a Burmese python, and most recently (unfortunately not yet available on YouTube) a two for one, lion and tiger combination.

I’m hoping they work in a ostrich or emu in there sometime soon and maybe a giant squid or octopus to show some invertebrate anatomy as well.

These programs deal with the dissection of actual animals in graphic detail so if you’re squeamish at all you might find them difficult to watch, however this show is an absolute must see for anyone interested in zoology and evolution.

Of particular interest was the dissection of the giraffe. Among the various interesting adaptations towards tree top browsing is a classic example of one of the cloven hoofprints of evolutionary history, the recurrent laryngeal nerve; the dissection of which has apparently not been done (according to one of the scientists in the show) in a giraffe since the 1830’s.

Here is the first episode of the first series on the Asian elephant:

A play list of all the videos available on YouTube can be found here, and I really cannot recommend them more highly.

Go watch them… NOW!

but there is a whole series of videos showing several different large animals being dissected while their anatomy, physiology, and how these evolved are discussed. A must see for those interested in zoology and evolution.

One more time with Biele

Creationist Arthur Biele responded to my response, to his response of my critique of something he wrote on horse evolution [inhales abruptly].

Thankfully he respected my wishes that he not post another book length set of arguments in the comments to my post. He has of course taken this as a blanket refusal on my part to allow him to respond:

Biele: Since you refuse me a full response to your article…

Mr. Biele, I only asked that you not post another extremely lengthy response, in the comments section of my blog and indeed this is a rule of mine, one not restricted to you. If you look at my comments policy you’ll see that this is a  request I make of everyone who comments on my blog. Still, I welcomed you to respond to one or two specific points, which we could then discuss further; something which I think would be a more productive way to continue our debate.  And I also specifically mentioned other options you could take if you wanted to respond at length.

Once again, you are free to start your own blog (they’re free) or web page and post as long a response to me as you like. Alternatively you could post your comments to the Talk Origins Newsgroup (or some other similar open forum), and simply leave a link in my comments as to where your response could be found (and then I might respond further here).

So it is really your choice.

Now, despite your complaints, you did in fact make a comment of a limited nature about punctuated equilibrium which I am happy to respond to.

Biele: …the PE’s views that theory is not at all complementary to Darwinisn evolution, but was meant to replace it.

Yes, I am aware that this is the caricature of punctuated equilibrium that antievolutionists like you believe in; the problem is it is a caricature, not reality. You see, Mr. Biele, for someone who has some understanding of both the neo-Darwinian synthesis and PE (and who has read the relevant literature), your portrayal of the situation is nonsensical.

Biele: In the plaeontologists views, evidence for Darwin’s gradualistic theory of evolution is refuted by the fossil record.

In some paleontologists’ views, the evidence for what Eldredge and Gould referred to as “phyletic gradualism” is refuted by the fossil record. Not Darwinian evolution as a whole, just what they termed its supposed phyletic gradualism. Furthermore, there are many, including myself, that think that Eldredge and Gould fashioned a bit of a straw-man in their characterization of the main-line synthetic theory.

Biele: The PE theory was a means to save The General Theory of Evolution by proposing a new means by which evolution occurs. Of course that theory of evolution also has its’ critical faults too.

[Sigh] I’m sorry Mr. Biele, but this is simply nonsense. Once again, Stephen Jay Gould:

Faced with these facts of evolution and the philosophical bankruptcy of their own position, creationists continually rely upon distortion and innuendo to buttress their rhetorical claim.  If I sound sharp or bitter, indeed I am – for I have become a major target of these practices.

I count myself among the evolutionists who argue for a jerky or episodic, rather than a smoothly gradual, change of pace.  In 1972, my colleague Niles Eldredge and I developed the theory of punctuated equilibrium.  We argued that two outstanding facts of the fossil record —geologically “sudden” origin of new species and failure to change thereafter (stasis) — reflect the predictions of evolutionary theory, not the imperfections of the fossil record. In most theories, small isolated populations are the source of new species, and the process of speciation takes thousands or tens of thousands of years.  This amount of time, so long when measured against our lives, is a geological microsecond.  It represents much less than one percent of the average lifespan for a fossil invertebrate species – more than 10 million years.  Large, widespread, and well-established species, on the other hand, are not expected to change very much.  We believe that the inertia of large populations explains the stasis of most fossil species over millions of years.

We proposed the theory of punctuated equilibrium largely to provide a different explanation for pervasive trends in the fossil record.  Trends, we argued, cannot be attributed to gradual transformation within lineages, but must arise from the differential success of certain kinds of species.  A trend, we argued, is more like climbing a flight of stairs (punctuations and stasis) than rolling up an inclined plane

Since we proposed punctuated equilibria to explain trends, it is infuriating to be quoted again and again by creationists – whether through design or stupidity, I do not know – as admitting that the fossil record includes no transitional forms.  Transitional forms are generally lacking at the species level, but they are abundant between larger groups.  Yet a pamphlet entitled: “Harvard Scientists Agree Evolution Is a Hoax” states: “The facts of punctuated equilibrium which Gould and Eldredge . . . are forcing Darwinists to swallow fit the picture that Bryan insisted on, and which God has revealed to us in the Bible.” – Gould (1983) “Evolution As Fact And Theory” in Hen’s Teeth and Horses Toes, pp.253-262, (Emphasis mine)

And now, 27 years later, Arthur Biele continues the distortion.

Biele: I was preparing a reply in my mind as I read each of your arguments and noting the many sophistical defenses you used in your long awaited reply. A long reply deserves an equal response, And it would have taken me a few days due to my busy schedule. But as you told me what amounts to be ‘take a hike’, that your site is reserved for your own views and accolades, I will honor your wishes. I indeed do plan to actually ‘take a hike’ as it would be good for my health.

As I said it’s your choice. You have several options open to you to give as long a response as you might like to my previous post, and of course you are welcome to respond on the more limited issue of PE discussed here in the comments below, just keep it concise.

If not, it’s no sand off my beach.

Smithsonian Magazine Editor Responds

Someone named Laura, who identifies herself as being an editor at the Smithsonian Magazine, left a comment on my post about their mix-up of hominid pictures in a paleoanthropology time line published in the March edition of the magazine and I figured I’d move it up to post level where more people would likely see it:

Troy, thanks for your post about Ann Gibbons’ story on Hominid Evolution in Smithsonian. I’m an editor there who worked on the story. We decided whenever possible to use images that would be easy for readers to understand. The timeline, especially, had to show many small images of specimens that some of our readers are reluctant to consider their ancestors. For Java Man, we did go with the more complete skull from the same place and species. We’re trying to figure out what happened with the Neanderthal image–the source we used labeled it as Neanderthal, but your comparison with Turkana Boy makes a good case. We’ll let you know if we figure out where the photo was taken and which specimen it shows.

First let me say thank you Laura for responding on this.

Regarding the Java Man thing, as I admitted in my post, I was perhaps being a bit nit-picky, and I don’t consider the switch from one Indonesian Homo erectus skull to another to be too much of a problem. However swapping out a H. ergaster (from Africa) for a H. neanderthalensis (mostly European) is obviously a different matter.  And while I am not a paleoanthropologist  and while I don’t even play one on the interwebs, I’ll bet you a years subscription to your magazine that you’ll find that the picture that was used to show a Neanderthal is instead a photo of the Turkana Boy.

Funny how I don’t get this sort of response from the antievolutionists who I catch making much larger mistakes than this (and I know some of them read this blog). Ah well…

We need creationists lecturing us on evolution like we need another fenestra in the head

The Institute for Creation Research has presented the world with another taxonomic turd from the cat box of creationist wisdom. This time it comes from ICR’s “Senior Science Lecturer” Frank Sherwin. However before I get to the main event, I want to take a closer look at the litter in which Mr. Sherwin’s little jewel is nestled.

In the February (2010) issue of ICR’s monthly Acts & Facts Mr. Sherwin (whose background is in parasitology) graced us with an article titled “Darwinism’s Rubber Ruler” in which he argues that descent with modification is untestable and that “any and all scientific evidence” can be “stretched to fit” the theory.

The first thing that comes to my mind when reading this is to ask: if this is so, then how is it that I could have in my personal collection literally hundreds of books and pamphlets, many of them originating from Mr. Sherwin’s organization, that purport to contain absolutely scads of evidence that contradict evolutionary theory?

How about Dr. Duane Gish’s (the emeritus vice president of ICR) books Evolution the Fossils Say NO! (1978) and the update Evolution: the fossils STILL say NO! (1995)? How can the fossils say “no” to evolution if any scientific evidence (in this case fossils) can be “stretched to fit” the theory?

Epic Horse Exhaust

OK, it took me a while to get to it but I am, as promised, responding to creationist Arthur Biele’s lengthy comments left in response to my criticisms of his writings on horse evolution. For those interested I suggest you go back and read Mr. Biele’s article and my original critique first. Those that do I think will find that his response didn’t really answer any of my original criticisms. Instead what he did was dump a new load of barely coherent nonsense on me.

A warning though, this goes on for quite a bit (it sure felt like it while I wrote it), which is of course due to the well known fact that accurately and substantially responding to horseshit takes considerably more time and effort than it does to spewing it.

Biele: With regard to Eohippus, If you knew anything about the actual fossil record, Eohippus finds are many and that category has been a dumping ground for certain archaic partial skulls that defy any specific classification, nor are they known to be ancestors of any known ‘evolved’ descendants, and they are mostly from Europe.

While apparently attempting to impugn my knowledge of the “the actual fossil record” Mr. Biele clearly demonstrates his own ignorance of the subject at hand. Let’s break this down in order:
