ScienceBlogling Mike Dunford reminds us that Michael Egnor's creationist stupidity, like Camus' plague, never disappears, but only wanes. Egnor has unleashed his formidable stupidity on the concepts of artificial and natural selection.
So many fucking morons, so little Mad Biologist. Fortunately, I've written about this before:
The difference between artificial selection and natural selection isn't that the selective agent (e.g., pesticides) is a result of human activity. The difference is in what determines what is the 'fittest': a person's decision as to what traits are preferable, or…
gregladen | March 10, 2008You may have noticed that I've been entirely silent about the movie Expelled. This is because of something that I do: Utterly ignore certain aspects of reality because my level of interest does not exceed my level of annoyance. I also ignore entire chunks of reality because I find them too interesting yet don't have the available time or energy to invest at the moment. Like the Maya. I've totally ignored the Maya for this reasn.
But, here's the thing: If you go to my old blog, which is a dormant archive, I've got a few Google ads set up, and they tend to display ads for Ben Stein,…

Yesterday I took John Wilkins to the Feathered Dinosaurs and the Origin of Flight exhibit at the Arizona Natural History Museum. It was a wonderful opportunity to see 30+ fossils from China along with assorted models and recreations, particularly of Deinonychus (above, particularly cool), Therizinosaurus, Microraptor, Cryptovolans, Confuciusornis, Caudipteryx, and Shenzhouraptor. Some of the exhibit can be seen here [pdf] in a brochure by the Utah Dinosaur Museum. While John and I were a little puzzled at some of the statements on the accompanying descriptions, the exhibit overall comes…
gregladen | March 9, 2008There are two books called "Icons of Evolution." One is by Jonathan Wells. The best way to learn about Well's Icons of Evolution is to watch Randy Olson's Flock of Dodos. It is an anti science piece of dreck.
The other is a more recently published is Icons of Evolution [Two Volumes]: An Encyclopedia of People, Evidence, and Controversies (Greenwood Icons), and it is an entirely different book. I have heard about this book, but not read it. Since it came up in a comment I thought I'd give you a direct link and a little bit of information. Info from the publisher:

gregladen | March 8, 2008Creationism's Trojan Horse: The Wedge of Intelligent Design is a must read for those interested in the Evolution - Creationism controversy. In particular, this volume is an essential part of the personal library of every science educator, for reasons that I will describe below. If you know a Life Science Teacher, this is a perfect birthday present. If you have a child in the public K-12 education system in the US, or the analog somewhere else, donate a copy of this book to the appropriate life science teacher!
In this important book published by Oxford University Press in 2004, Forrest…
gregladen | March 7, 2008Scott Rowed published an Op Ed piece in the Calgary Herald last October that has just come to my attention. It is about evolution in schools in Canada, and provides an interesting perspective.
Should we reward them with taxpayers' money to pass on these wonderful insights to the next generation? Should our future leaders learn to smother their critical thinking and make decisions based on faith rather than evidence and reason? From Canada, we don't have to look too far south to see how tragic these faith-based decisions can be.
Read the whole thing here.

gregladen | March 7, 2008.... Have you ever had this happen: You are minding your own business, teaching your life science course, it's early in the term. A student, on the way out after class (never at the beginning of class, rarely during class) mentions something about "carbon dating." This usually happens around the time of year you are doing an overview of the main points of the course, but before you've gotten to the "evolution module" (more on the "evolution module" another time ... or come to the Bell on Friday to hear me rant about that in person).
Jeanne d'Arc was a very influential 10th grader. I…
pharyngula | March 7, 2008My last column in Seed is now online for you cheapskates (OK, you're forgiven already) who don't subscribe. It's called "Eyeing the Evolutionary Past," and discusses a familiar topic around these parts — the evolution of eyes.

One of Gerhard Heilmann's color illustrations of Archaeopteryx that graced his classic book The Origin of Birds. For more of Heilmann's excellent artwork, see this website.
Birds are extant dinosaurs; it's a phrase that (while initially quite stimulating) has been expressed so often that it borders on being trite. There are dozens of technical papers, popular books, collections of scholarly essays, and feathered dinosaur toys to drive the point home, but I've often been led to wonder what ornithologists make of all this. Paleontologists have been the main architects that have strengthened…

There's not much to add in terms of rebutting intelligent design creationist Jonathan Wells' latest misappropriation of science that Larry Moran, Orac, and Ian Musgrave didn't already write. But Wells' latest screed demonstrates just how pathetically low intelligent design creationism has sunk. An argument that stupid is a tacit admission of defeat.
Essentially, Wells' argument can be summarized as "if evolutionary biology isn't cited in every single biology paper EVAH!, then evolutionary biology isn't relevant to biology." Never mind that every step in genomic biology involves…
clock | March 7, 2008News from SCONC:
On Thursday, March 27 at 4 p.m., the Zoology Department at NCSU will host a seminar from Patricia Brennan of Yale University entitled "The Biology of Avian Genitalia: Form and Function." Brennan's work on the genital anatomy of waterfowl has revealed the existence of a "sexual arms race" between males and females. Unlike 97 percent of bird species, male waterfowl have a phallus, and it can range "from a half-inch to more than 15 inches long." The seminar will be held in 101 David Clark Labs. Refreshments will be served in the lobby at 3:45.

I (and apparently Jim Lippard) went to see Dawkins' talk based on his The God Delusion, which I have critiqued before. I was impressed at the technique. It was definitely the very best Revivalist Sermon I have seen. I was not impressed by the content, nor by the fact that Dawkins was playing for laughs, applause and identification of Us versus Them.
In particular I was annoyed that those of us who do not condemn someone for holding religious beliefs were caricatured as "feeling good that someone has religion somewhere". Bullshit. That is not why we dislike the Us'n'Themism of TGD. We…
pharyngula | March 6, 2008Teachers, come to Minneapolis this summer! Not for the Republican convention, but for the other great big important meeting that will be taking place: Evolution 2008.
Teachers in particular get a really good deal: a special workshop is planned, specifically on the teaching of evolutionary biology in the schools. We've got some good speakers (and me) lined up, and the registration cost of a mere $20 not only gets you into the workshop, but into the regular meetings as well. Here are the details:

evolgen | March 6, 2008Olivia Judson (aka, Dr. Tatiana) has a blog at the NYTimes website. It's usually a good read, but she has been known to go off the deep end. In this week's entry, Judson posts on how bones are not the only fossils. What other fossils does Judson write about? Genomes.
Judson's focus is on genome size. She's clear that differences in genome size are the result of stuff other than genes, but she doesn't want to call that extra stuff "junk". Here's why:
I don't like "junk," which suggests the DNA is useless: even if it doesn't hold the instructions for making proteins, it may still serve a…
razib | March 6, 2008Genetic evidence and the modern human origins debate:
A continued debate in anthropology concerns the evolutionary origin of 'anatomically modern humans' (Homo sapiens sapiens). Different models have been proposed to examine the related questions of (1) where and when anatomically modern humans first appeared and (2) the genetic and evolutionary relationship between modern humans and earlier human populations. Genetic data have been increasingly used to address these questions. Genetic data on living human populations have been used to reconstruct the evolutionary history of the human species…
gregladen | March 6, 2008There is a new paper out suggesting that the Flores hominids, known as Hobbits, were "human endemic cretins."
From the abstract of this paper:
... We hypothesize that these individuals are myxoedematous endemic (ME) cretins, part of an inland population of (mostly unaffected) Homo sapiens. ME cretins are born without a functioning thyroid; their congenital hypothyroidism leads to severe dwarfism and reduced brain size, but less severe mental retardation and motor disability than neurological endemic cretins. We show that the fossils display many signs of congenital hypothyroidism, including…

Yes, this is O157:H7, not ExPEC. Bully for you.
One thing regarding popular accounts of antibiotic resistance I've noticed is that there is an overemphasis on the evolution of resistance, and an underemphasis on the spread of resistant bacteria. While the evolution of resistance is important, most of what we see in a hospital is not the de novo change of a sensitive strain into a resistant one (i.e., evolution), but, instead, the survival and spread of already resistant bacteria in this antibiotic-laden environment.
What this means is that changes in the frequency of resistant organisms,…
laelaps | March 5, 2008In July of this year, 16 hand-picked scientists will meet at the Konrad Lorenz Institute in Altenberg, Austria to discuss the current state of evolutionary theory. The papers presented at the meeting will be published next year and I'm sure it will generate some amount of discussion, but I have to wonder just how significant this event is going to be. We shouldn't expect 16 scientists to get together, pick each others brains for a bit, and then emerge from the meeting carrying with them a shiny new "Extended Evolutionary Synthesis" that will rewrite everything. The development of the "Modern…
pharyngula | March 5, 2008I and a diverse group of people got a question in email, one that we are supposed to answer in a single sentence. The question is,
What is evolution?
You know, Ernst Mayr wrote a whole book to answer that question on a simple level, and I'm supposed to have the hubris to answer that in one sentence? OK, knowing full well that it is grossly inadequate, here's my short answer:
Evolution is a well-confirmed process of biological change that produces diversity and coherent functionality by a variety of natural mechanisms.
Go ahead, you people try to answer it in one sentence in the comments.…
