A WTF Moment in Texas

| 13 Comments (new) | No TrackBacks

I’ve just started reading Kenneth Miller’s Only A Theory in which he is attempting to make the case that the current assault on science, orchestrated by organizations like the Disco ‘Tute, is a “threat to our ‘scientific soul’ – the healthy skepticism and rational respect for truth that has fueled our remarkable scientific advances” (from the dust cover copy).

One might imagine that Miller is being alarmist, but then one encounters this. At the current hearings of the Texas State Board of Education on its new science standards, Jonathan Saenz, a functionary in an affiliate of Family in Focus, made this extraordinary remark:

Darwin was from England and Einstein was from Germany. The elitism and arrogance that has been going on is not what Texas is about.

That’s the kind of abject stupidity that could convince me that Miller is right. How many Pastor Ray “We’ve been attacked by the intelligent, educated segment of the culture” Mummerts are there?

From Homeroom: An education blog, via John Pieret.

Wes Elsberry has a good summary post with links on the hearings that the Texas State Board of Education held yesterday on the crypto-creationist “strengths and weaknesses of evolution” language in some drafts of the new standards. The overwhelming public testimony was in favor of teaching the best science available, i.e. evolution as a well-confirmed, central theory of modern biology, without the presence of crank creationist propaganda. But many members of the board are fundamentalist creationists and just can’t bear the thought that Texas science classes should teach standard science. Instead they repeatedly launched into traditional, hackneyed, long-refuted, ignorant creationist/ID talking points. A short list from Wes (I can confirm that I heard all of these while listening to the live audio):

Piltdown man (Ken Mercer)

Haeckel’s embryos (Ken Mercer)

Macroevolution not observed (Ken Mercer)

Argument from authority (Terri Leo)

Evolution is only a theory (various)

“Academic freedom” (Ken Mercer)

Evolution is not a fact (witness)

Eminent scientists are rejecting evolution (Cynthia Dunbar) [this was largely waving around the Discovery Institute “Dissent from Darwin” list…no discussion of the statement’s incredible vagueness, the dubious expertise/scientific status/noncreationist status of many on the list, or of how many Steves were on it – Nick]

When does a theory become a law? (Don McLeroy)

Evolution critics are censored (Ken Mercer)

Polystrate fossils/Lompoc whale (Gail Lowe)

…so those are the folks determining science education in the second biggest population state in the country. What century is it again?

Only two weeks remain, and there is a lack of nominations from the Panda’s Thumb. Your mission, readers, is to find our best articles from the last year and nominate them from the Panda’s Thumb. The rumor I’m hearing is that anti-anti-evolution blog posts are going to get the shiv this year, so try to focus on posts that are not responses to the stupidity that is (“intelligent design”) creationism.

The Luskin Follies, Part MCMLVIII

| 30 Comments (new) | No TrackBacks

Last month PvM posted on Casey Luskin’s misconceptions based on some remarks reportedly made by Catherine Boisvert in a news story on the resolution of the distal radials of Tiktaalik.

However, as PvM pointed out, Boisvert’s research using MicroCT scans, discussed in that news article, actually resolved those elements of a Tiktaalik:

The disposition of distal radials in Panderichthys are much more tetrapod-like than in Tiktaalik,” Boisvert wrote. “Combined with fossil evidence from Tiktaalik and genetic evidence from sharks, paddlefish and the Australian lungfish, it is now completely proven that fingers have evolved from distal radials already present in fish that gave rise to the tetrapod.

Now Chris of A Free Man, a geneticist in Australia, has interviewed Boisvert about Luskin’s misuse of her remarks and her work with the specimens. The money quote:

As you know, the “Discovery” Institute tactic is not to go to the primary literature in order to understand it but rather to use quotations from secondary, even tertiary sources, reorganise or use them out of context opportunistically to their own convenience. In this case, they used an article where the journalists unfortunately misunderstood me. Tiktaalik’s material is in fact exquisite, it is very well preserved, basically uncrushed and can be prepared out to be examined in three dimensions. I never said the quality was poor. I have simply explained that the morphology of the fin of Panderichthys is more tetrapod-like than that of Tiktaalik, which has nothing to do with the quality of the material.

That pretty much settles it, I’d say.

As a follow-up to P.Z.’s post on evolution and entropy, I have added some context to the thermodynamics argument in this post over at EvolutionBlog (comments may be left there.)

Oberlin College physicist Daniel Styer has published a brief, but very useful, article in The American Journal of Physics showing that even under very conservative assumptions the change in entropy of the biosphere as the result of evolution is negligible compared to the entropy flux of the Earth that results from the Sun’s heating. Sadly, I know from personal experience that this sort of thing tends to leave creationists unimpressed. This is because their arguments use only the language, but not the substance, of thermodynamics. Their assertion that evolution violates the second law is not really an invitation to carry out entropy calculations. Rather, it is just another incarnation of ye olde argument from incredulity, in which they express the difficulty they have in believing that fully naturalistic processes can explain the growth in complexity in organisms over time.

I provide some details in my post. Enjoy!

Daniel J. Phelps is President of the Kentucky Section of the American Institute of Professional Geologists and Chairman of the Geology Section of the Kentucky Academy of Science. He is also founder and President of the Kentucky Paleontological Society, a well-respected amateur paleontological organization.

Dan is also among the most active scientists in debunking Answers in Genesis’ Creationism Museum, to the point that AIG whines about it. Dan has been tireless in critiquing the museum and the faux “science” it promotes.

Now Dan has been named Distinguished Professional Scientist in a Non-academic Position by the Kentucky Academy of Science. Congratulations to a committed supporter of science and honest science education!

Entropy and evolution

Blogging on Peer-Reviewed Research

One of the oldest canards in the creationists' book is the claim that evolution must be false because it violates the second law of thermodynamics, or the principle that, as they put it, everything must go from order to disorder. One of the more persistent perpetrators of this kind of sloppy thinking is Henry Morris, and few creationists today seem able to get beyond this error.

Remember this tendency from order to disorder applies to all real processes. Real processes include, of course, biological and geological processes, as well as chemical and physical processes. The interesting question is: "How does a real biological process, which goes from order to disorder, result in evolution. which goes from disorder to order?" Perhaps the evolutionist can ultimately find an answer to this question, but he at least should not ignore it, as most evolutionists do.

Especially is such a question vital, when we are thinking of evolution as a growth process on the grand scale from atom to Adam and from particle to people. This represents in absolutely gigantic increase in order and complexity, and is clearly out of place altogether in the context of the Second Law.

As most biologists get a fair amount of training in chemistry, I'm afraid he's wrong on one bit of slander there: we do not ignore entropy, and are in fact better informed on it than most creationists, as is clearly shown by their continued use of this bad argument. I usually rebut this claim about the second law in a qualitative way, and by example — it's obvious that the second law does not state that nothing can ever increase in order, but only that an decrease in one part must be accompanied by a greater increase in entropy in another. Two gametes, for instance, can fuse and begin a complicated process in development that represents a long-term local decrease in entropy, but at the same time that embryo is pumping heat out into its environment and increasing the entropy of the surrounding bit of the world.

It's a very bad argument they are making, but let's consider just the last sentence of the quote above.

This represents in absolutely gigantic increase in order and complexity, and is clearly out of place altogether in the context of the Second Law.

A "gigantic increase in order and complexity" … how interesting. How much of an increase? Can we get some numbers for that?

The Museum of Science at Boston has a fantastic interactive web resource on the origins of life. Exploring Lifes Origins has a timeline of lifes evolution (with sliders), and pages on understanding the RNA world and building protocells, with a nice animation of protocell replication. The pages have been made in collaboration with ribozyme guru Jack Szostak and his laboratory, and there is a handy resources page for educators.

If you are interested in our current understanding of the origin of life, this is a very handy starting off point. You can explore ribozymes in more detail with proteopedia.

We Are SVP - the Movie

| 1 Comment (new) | 1 TrackBack

The Society of Vertebrate Paleontology has come up with a very well-produced video introduction to the Society.

The Society’s website says

WE ARE SVP is a 33-minute video that tells the inside story of the Society of Vertebrate Paleontology – who we are, what we do, and why our work is important for science and society. The video is introduced and narrated by Sam Waterston, the long-time star of “LAW & ORDER.”

While the whole video is worthwhile, some of you may want to go straight to Chapter 4, “Evolution Vs. Creationism.” It’s got Kevin Padian and more., Go ahead - you know you want to.

Cheers, Dave

Innovative Teaching of Evolution

I made reference to this in a comment, but thought I’d promote it. The Guardian has a video up on innovative approaches to teaching evolution to secondary school students in Great Britain. It also interviews Martin Reiss, the recently resigned/ousted Education Officer of the Royal Society.

Added in edit: John Pieret has a post on a survey associated with the show. (Though I apparently can’t send a trackback there.)

Over on UD Denyse O’Leary is complimenting Alfred Russel Wallace for his 1907 critique of Percival Lowell’s claims that Mars was inhabited by intelligent, canal-building Martians. She says:

What made Wallace so unpopular compared to Darwin is that he insisted that in science, evidence matters. Carl Sagan-style proclamations like “They’re out there! How could we be so arrogant as to think we are all alone!” do not become science just because they are proclaimed by scientists.

First, the idea that Wallace was ever wildly unpopular is ridiculous, he was a grand old man of evolution and British science when he died. Second, if Wallace insisted that evidence matters and O’Leary likes this, then I guess she considers this a strong vote for common ancestry and natural selection, both of which Wallace defended as vigorously as anyone. We evolutionists win I guess. Third, let’s have a look at what Wallace actually said about Lowell’s hypothesis that intelligent designers were the best explanations for the patterns he thought he saw on Mars:

Equus asinus — Donkey

The site of Dmanisi in the Republic of Georgia has produced four superb hominid skulls ranging in size from 600 cm3 to 780 cm3. These sizes range from the lower end of Homo erectus downwards into the Homo habilis range. The fossils contain a mixture of anatomical features from erectus and habilis. They could arguably be considered to belong either to primitive H. erectus (or H. ergaster), or to a new species, Homo georgicus. Vekua et al 2002 concluded:

The Dmanisi hominids are among the most primitive individuals so far attributed to H. erectus or to any species that is indisputably Homo, and it can be argued that this population is closely related to Homo habilis (sensu stricto) as known from Olduvai Gorge in Tanzania, Koobi Fora in northern Kenya, and possibly Hadar in Ethiopia.

These skulls are intermediate in both anatomy and size between Homo erectus and H. habilis, and as a result are exceedingly difficult for creationists to classify. Creationists therefore either ignored them (the usual reaction), or were forced into the absurdity of claiming that the biggest skull is human but the smallest two are apes (Lubenow 2004), or the almost equally implausible suggestion that all of them are human (Line 2005).

In 2007, further light was thrown on the Dmanisi hominids with the announcement that a substantial number of bones from below the skull had been discovered (Lordkipanidze et al 2007). These included a right femur, tibia and kneecap (the most complete known lower limb of early Homo); an ankle bone, part of a shoulder blade, three collar bones, three upper arm bones, five vertebrae, and a few other small bones. Some of these bones were associated with some of the previously discovered skulls.

Analysis of the bones shows that the Dmanisi hominids definitely walked bipedally and upright. However, the bones show a number of differences from modern humans and have some features associated with Homo habilis. The upper body differences lead the authors to suggest, with some caution, that “the Dmanisi hominins would have had a more australopith-like than human-like upper limb morphology”.

Their final conclusion was:

Freshwater Day 6: Another student, another cross

| 33 Comments (new) | 1 TrackBack

Day 6 of the Freshwater administrative hearing was on October 31, 2008. Testifying were Paul Souhrada, an editor of the Columbus Dispatch and the parent of a student in Freshwater’s class; Souhrada’s son Simon; Richard Cunningham, chairman of the high school science department; Katie Beach, a middle school intervention specialist; Kerri Mahan, a middle school special education teacher; and Katherine Button, a former student in Freshwater’s 8th grade science class.

Important note: I did not get to the hearing in time to get a seat for the morning session. My summary of the morning (Paul and Simon Souhrada, Cunningham, and Beach) is based on an hour-long interview later that day with two people who were at the morning session and who took notes. So it’s second-hand information to me and third-hand to you. I did have a seat for the afternoon session (Mahan and Button). For another view on that morning’s testimony see the Columbus Dispatch story. I’ve used that story and the Mount Vernon News story as additional sources for the Friday morning session. Reporters Dean Narcisco (Dispatch) and Pam Schehl (News) were at the morning session.

More below the fold.

The last two days of this installment of the hearing on John Freshwater’s appeal of the decision of the Mt. Vernon City Board of Education were on October 30 and 31. Once again I’ll summarize rather than try to present a sequential account of questions and answers. This post is Day 5; the next will be Day 6. I hope to have Day 6 written and posted sometime tonight.

Previous posts on the hearing: Days 1 & 2 and Day 3 and Day 4.

See also the coverage of Day 5 in the Mount Vernon News.

Day 5 saw the completion of cross examination of Bill White, Principal of the middle school in 2007-2008, and the testimony of Kathy Kasler, the high school Principal; David Levy, M.D., an expert witness; and Bonnie Schutte, a high school science teacher.

Politics impacts science. From which research emphases get funded to which school board member to vote for, science and politics often cross paths. PT’s supporters come from all walks of life and bring to the pro-evolution discussion opinions on other matters that span everything from conservative to liberal. To the extent possible, PT tries to avoid overtly being political, partly because we don’t want to needlessly alienate those supporters, but mainly because it’s beyond the charter of this website and that there are many other blogs that serve that purpose better than ours. Occasionally, though, this blog encounters a crossroads between science and politics, entailing posts that necessarily make political statements. This is one.

During this election, there is a difference between the candidates running for president. Palin is a creationist of the first water. Her disbelief that money spent in support of autism research was going to labs in France that used fruit fly models, reported at Pharyngula, speaks volumes.

At least from the standpoint of science advocacy and at least to this PT contributor, the decision during this election appears straightforward. Nature’s endorsement is timely and appropriate.

PS - And novel! According to this post from DailyKos.com, it would appear that this is first time Nature has endorsed a candidate.

Day 5 of the Freshwater hearing was today, but my post on it won’t be up until tomorrow night at the earliest. Tonight my seminar on the history of the controversies surrounding the theory of evolution is going to a Chautauqua performance about Clarence Darrow, and then I’m going to bed.

As a consolation prize read Glenn Branch’s Zombie Jamboree in Texas in the Beacon Broadside. Texas is heading for a potential disaster in science education.

Freshwater Day 4: “Science can’t be trusted”

| 29 Comments (new) | No TrackBacks

Preceding posts: Day 3 and Days 1 & 2. This summarizes Day 4, October 29, 2008.

I’ll take a slightly different approach in this post for several reasons. First, I’m short of time and sleep. Second, much of the day was given over to cross examination of the middle school principal by Kelly Hamilton, Freshwater’s attorney, and Hamilton’s approach to cross examination does not lend itself to any sort of narrative flow. Therefore I’ll summarize the main themes of the testimony with some examples of Q&A rather than attempting to reproduce the exact sequence of questions through hours.

The bulk of the testimony today was from Bill White, Principal of the Mt. Vernon Middle School. Another student, a former student of Freshwater who is currently a senior at Mt. Vernon High School, also testified.

Freshwater Hearing: 3rd Day

| 34 Comments (new) | No TrackBacks

This is a summary of Day 3 of the administrative hearing to determine whether John Freshwater will be terminated as a middle school science teacher in the Mt. Vernon, Ohio, City Schools. Days 1 and 2 are here.

Three witnesses testified today, Zachary Dennis, the boy who was (allegedly) burned with a Tesla coil, his mother Jenifer Dennis, and Freshwater. We’re still in the stage where the Board of Education is presenting its case for termination; later Freshwater will be allowed to put on a defense.

Summaries below the fold.

The mother of the boy at the center of the Freshwater affair, Jenifer Dennis, has given her first interview to the Columbus Dispatch. Two excerpts:

Zachary Dennis, now a high-school freshman, told his mother that his eighth-grade teacher, John Freshwater, held his arm down Dec. 6 and used an electrical device used to test gases to burn a cross on his forearm during a science class demonstration.

“He said ‘Mr. Freshwater said this cross will be here for awhile; it’s like a temporary tattoo,’ “ recalled Jenifer Dennis, Zachary’s mother.

and

“We never intended to go in to get Mr. Freshwater in trouble,” said Mrs. Dennis. “I send my child to school and expect my child not to come home with an injury to his arm.”

I know the Dennis family, and know that they originally wanted only to assure the safety of Zach and the other children in Freshwater’s classes. Freshwater’s other behaviors at issue came to light in the aftermath of his burning the child and his subsequent publicity seeking via demonstrations outside the schools and on the Mt. Vernon public square.

The termination hearing on Freshwater resumes tomorrow (Tuesday). I’ll be there.

Information content of DNA

The information content of DNA is much harder to determine than merely looking at the number of base pairs and multiplying it by 2 to get the size in bits (remember that each site can have up to 4 different nucleotides, or 2 bits). However, this approach can provide us with a zeroth order estimate of the maximum possible information that can be stored in said sequence which for the human genome with 3 billion base pairs would amount to 6 billion bits or 750 Mbytes.

After 20 days, Religulous has grossed more than Expelled during its six months in US theatres.

Funny how despite give aways, pre-screenings and discounts, and much marketing to the religious, Expelled did not manage to attract more audience than Religulous. What is even more ironic is that Religulous outperformed Expelled from the opening weekend with half the theatre count.

In a hilarious posting on UcD, our dear friend Davescot, who is best known for his failed predictions 1, explains why recent research into the Lactose digestion of E. coli, undermines the findings of Lenski regarding E. coli evolving the ability to digest citrate. The reason? Our friend Davescot confused citrate with the Lac Operon

Davescot Wrote:

This is contrary to Lenski’s hypothesis that a series of dice throws, each making a small change towards ability to digest lactose citrate, accumulate until lactose citrate digestion is fully switched on. Darwinian gradualism is denied once again and we see a front loaded genome switch to a new mode of operation through a saltational event.

In other words, Davescot made two mistakes in a single posting: first he confused citrate with the Lac operon and secondly, he incorrectly claims that ‘Darwinian gradualism’ is denied once again, because, after all, a stochastic event affects whether E. coli can digest lactose versus glucose.

According to the ID ‘argument’, since chance and regularity can in fact explain the Lac Operon’s switch, any design inference has been prevented. Which is why Davescot, calls it ‘front loading’ or a ‘saltational’ event.
