Jupiter!

December 24, 2010 • 3:05 pm

This isn’t evolution, but it’s too amazing not to post.  It’s a movie of an entire rotation of Jupiter, made over several hours by Damian Peach in Barbados.  (Jupiter, huge as it is, rotates on its axis in a bit less than ten Earth hours.)  I found this at Bad Astronomy, where Phil Plait gives the details.  Peach’s website has even more photos and information.

Kitteh contest entry: Basil

December 24, 2010 • 6:35 am

Here’s another awesome entry, submitted by owner Tom. Check out the links.

So, here is my cat, Basil (oriental shorthair, solid grey, male, neutered), when he was still a kitten and just getting his adult fangs. Although he’s named after the herb, he also responds to Baz, and Fawlty Towers’ Sybil toned BaaSIIIILLLL! We also call him Basil the Rat. Our other cat is an oriental, ebony ticked mackerel tabby, Meeka (female, spayed), aka Sneekerpop, and ‘snake in a bear suit’. Baz came with us to Singapore from Australia, while Meeka was born here (SG). We don’t show them, but my wife and I both had orientals while we were growing up and reckon they’re obviously the best kittehs. Loud and talkative, extremely active, and affectionate.  Meeka is younger and more energetic, constantly delighting in giving baz a swipe as he’s wandering past. Sometimes he retaliates. Meeka is also the smart one, while baz likes to relax with a cold one at the end of the day.

Is that a nudibranch in your mouth, or are you just glad to see me?

2010’s new species

December 24, 2010 • 6:14 am

The United Nations declared 2010 “The Year of Biodiversity,” and as it draws to a close I wanted to highlight a few of the weird and interesting species found this year.  But remember that I’m just showing the bizarre or intriguing ones.  There are lots of less charismatic species discovered this year whose biology, when known, may be even more interesting.

A striped sea urchin, found by the remotely operated vehicle (ROV) Little Hercules during deep-sea dives off Indonesia in 2010.  You can see a stunning collection of photographs of fifty-odd creatures seen during the dives here.

A barrel sponge, also found by the Hercules:

This year also saw the discovery of the world’s longest insect, the phasmid Phobaeticus chani from Borneo. Exceeding the previous record holder (another stick insect) by 29 mm—a bit more than an inch—it was found in a private collection, and there are apparently just three specimens. Measurements: 14.1 inches (35.8 cm) head to tail, 22.3 inches (56.7cm) including legs (there’s a description and a lovely video from London’s Natural History Museum). Here’s the big specimen; the ruler is 30 cm long (11.8 inches):

Here’s a different species (I think it’s Australia’s titan stick insect, Acrophylla titan, but I’m not sure), showing how large they get.  Stick insects are now placed in the order Phasmatodea (they’re called “phasmids” by entomologists); they were previously put in the order Orthoptera with crickets and grasshoppers, but have now been separated.  

And a nice Attenborough video on stick insects, from the Life in the Underground series.  This species has a remarkable adaptation: it lays eggs that resemble seeds that are collected and eaten by ants.  The ants take the seed-mimic eggs to their nests, but don’t eat them.  There, protected from predators and the elements, the eggs eventually hatch—sometimes after as long as three years!—to produce a new generation of stick insects.

Two new proboscoidally challenged species were also discovered this year. One is the tubed-nosed fruit bat in the genus Nyctimene, found during an expedition to Papua New Guinea. I’m not at all sure why the nostrils are tubular; could it be to help them localize food?

For obvious reasons it’s nicknamed “the Yoda bat”:

The other is a long-nosed tree frog, also found on New Guinea:

L.A. Unleashed describes its discovery:

An international team of researchers was camping in the Foja mountains of Indonesia when herpetologist Paul Oliver spied a frog sitting on a bag of rice in the campsite.

On closer look it turned out to be a previously unknown type of long-nosed frog. The scientists dubbed it Pinocchio.

When the frog is calling, its nose points upward, but it deflates when the animal is less active.

“We were sitting around eating lunch,” recalled Smithsonian ornithologist Chris Milensky. Oliver “looked down and there’s this little frog on a rice sack, and he managed to grab the thing.”

Here’s a bizarre creature, also photographed in the deep waters off Indonesia by the Little Hercules, that I can’t identify.  Perhaps a reader knows what this is:

Finally, this doesn’t happen very often: a putative new species of primate, the snub-nosed monkey, was discovered in Myanmar.  I’m a bit dubious about this one since the species, Rhinopithecus strykeri, was apparently designated as new based on color differences from existing snub-nosed monkeys and the fact that the “species” (consisting of a few hundred invidividuals) was geographically isolated from others.  But that’s not a good way to name a new species:  as we know, different human groups (which were once geographically isolated) differ in pigmentation and other traits, but nobody claims that ethnic groups correspond to different species of humans.  This primate “species” could just be an ecotype.  Anyway, the BBC reports:

Evidence from hunters also suggested that the monkeys were particularly easy to find in the rain. The monkeys allegedly sneeze audibly when rainwater gets in their noses and local people said they could be found with their heads tucked between their knees on rainy days.

Here’s a digital reconstruction of the beast, which apparently has not been photographed close up:

To paraphrase Monty Python, “Every species is sacred.”  Each one has a tale of ecology and evolution to tell—a tale that’s lost forever if the species goes extinct.

The 100 most beautiful English words

December 23, 2010 • 6:34 pm

. . . at least according to linguist Robert Beard at alphaDictionary.  The first one on the list (“ailurophile”) is, of course, de rigueur for readers here, but my other listed favorites include conflate, desuetude (also a favorite of Hitchens), efflorescence, emollient, imbroglio, insouciance, lagniappe, languor, palimpsest, propinquity, scintilla and seraglio.

But where are kerfuffle, portentous, tendentious, rodomontade, mufti, and hauteur? (Note that several of these are taken from other tongues.)

What are your favorites not on the list?

Foul-weather footwear

December 23, 2010 • 12:06 pm

When it threatens to snow, as it does today in Chicago, it’s no good wearing fancy boots that can get wrecked by slush and salt.  But here’s a sturdy and inexpensive pair that stands up to the elements. Guess the hide (no prizes!)

UPDATE: Somebody finally guessed: see comment #47 and my reply.

Ruse: The gift that keeps on gibbering

December 23, 2010 • 8:30 am

UPDATE:  Over at EvolutionBlog, Jason Rosenhouse, the original inspiration for Ruse’s ire, has responded to his dumb Constitutional argument.

 

I try to keep this website classy, so, in response to Michael Ruse’s latest public display of stupidity, I’ll refrain from calling him a “clueless gobshite”.  Let’s just say that his brain has passed its sell-by date.  And just when you think his arguments can’t get any loonier, he comes up with a new one.  This time he argues that anyone who maintains that science and religion are at war, and are mutually exclusive constructs, is begging for the courts to ban science from public school classrooms.

Ruse’s piece is in response to a surprisingly strong article by David Barash, “NOMA? No thanks!” at his blog at the Chronicle of Higher Education.  Barash has no truck with the popular accommodationist view, made famous by Steve Gould, that science and religion are happily coexisting and non-overlapping magisteria (“NOMA”):

Rather, let’s acknowledge the truth: Science and religion overlap substantially, notably whenever religion makes “truth claims” about the world.  And when that happens, time and again, religion has a long track record of being simply and irretrievably wrong. . . of course it is possible to argue that God created evolution by natural selection—presumably, along with Newton’s Laws, relativity, quantum mechanics, the 2nd law of thermodynamics, coordinate covalent bonds, and so forth—and then backed away, letting the system run according to these accumulated natural laws.  But the reality—at least in my not-so-humble opinion—is that anyone who claims to espouse both science and religion is being intellectually dishonest or else lazy, and is necessarily short-changing one perspective or the other.

Ruse, in contrast, is a long-time accommodationist, and, though an atheist, spends a lot of time devising ways that the faithful can reconcile their beliefs with science.  His own Chronicle piece, “From a curriculum standpoint, is science religion?“,  is nominally a rebuttal of Barash, but also serves the two other purposes Ruse always instills in his essays.  First, he uses them to sell his latest book—two of them in this case (I won’t name them).  Ruse’s books don’t sell that well—certainly not as well as the books of Gnu Atheists—and he’s always resented that deeply.  But there’s a good reason for this disparity: at least over the last decade, Ruse has written the same book over and over again, and not very well, either.

Second, Ruse loves to lick his wounds in public, and never misses a chance to trot out the epithets he’s garnered from atheists.  Gruff and nasty as he is, he has a thin skin:

In the case of people like me, those who endorse the independence option, our fellow nonbelievers are scornful to an extent equaled only by their comments about Pope Benedict.  We are labeled “accommodationists” or “appeasers,” and reviled.  Just earlier this week I got flak for suggesting that perhaps St. Augustine on original sin was not the last word on the subject and that a more evolutionary friendly interpretation can be found in the second-century thinker Irenaeus of Lyon.

Note that the “I got flak” statement links to my website, but there I was merely drawing attention to a critique of Ruse by Jason Rosenhouse at EvolutionBlog. The serious flak came from Jason.

Before Ruse arrives at his most monumentally idiotic argument, he takes time to make a few others.  First, he tries to equate science and faith by claiming that science, too, is based on a metaphor—a metaphor that makes certain questions unanswerable unless you’re an exponent of the dreaded practice of scientism.   And he then claims that religion is a valid way to answer these questions:

Basically, I argue that science is inherently metaphorical, that today’s science has at its core the metaphor of a machine, that metaphors rule certain questions out of court—not wrong, just not asked—and that it is legitimate for religious people to try to provide answers.  Religious answers not scientific answers, about ultimate origins and purposes, about morality, and perhaps also about consciousness.

First of all, science is not based on a “metaphor”, which my online dictionary defines as “a thing regarded as representative or symbolic of something else.”  I believe Ruse uses the word “metaphor” here to denigrate science, putting it on the plane of religion, which for many is based on regarding sacred texts as metaphors.  Instead, science is based on the idea that we can gain understanding of our universe by applying principles of logic, observation, experimentation and reason.  That’s not a metaphor.  Yes, Descartes analogized organisms as machines, but we don’t think of that as a metaphor—it’s a reality.

And yes, of course it’s legitimate for religious people to try to provide answers.  It’s just that those answers are either wrong, conflict between different religions, or aren’t really the answers people apply in their daily lives.  And even if religion provides the illusion of giving answers, that doesn’t mean that the tenets of religion are correct.  There must be a name for the fallacy that confuses the religously-based search for truth by believers with the legitimization of the existence of God and of the empirical tenets of a faith.  Scientology is also a way to find “answers” about life, but that says nothing about the existence of Xenu and thetans.

Another dumb assertion:

We recognize that of course science and religion can conflict.  That was why we were in Arkansas.  But our argument—my argument, let me speak for myself—is that much that conflicts with science is not traditional religion but (in the case of Christianity certainly) stuff added on, mainly in the 19th century for social and political reasons.

Unless I miss my guess, accepting the literal truth of scripture, which is the real reason for the conflict between science and faith, had a long, long history before the 19th century—say, about 1900 years.  Yes, science as it’s practiced today wasn’t around for most of that time, but the conflict between fantasy and reality was.  The conflict only became evident when we began finding out stuff about the universe that wasn’t in the Bible, culminating with evolution.  Regardless of the dumb arguments about Galileo, the conflict was immanent all along, and had little to do with social and political issues.

But Ruse’s main point—an argument of (excuse the allusion) breathtaking inanity—is that we must be accommodationists and accept the happy coexistence of science and faith.  For if we don’t, and maintain that science and faith are mutually exclusive and that science implies atheism, then teaching science becomes equivalent to teaching “religion” (i.e., atheism). Since the American Constitution prohibits discrimination against religion (or among religions) in public schools, non-accommodationism will lead, says Ruse, to the courts ejecting science from school curricula:

So my question (and it is a genuine one, to which I don’t have an answer) to David Barash is this.  Suppose we agree to the conflict thesis throughout, and that if you accept modern science then religion—pretty much all religion, certainly pretty much all religion that Americans want to accept—is false.  Is it then constitutional to teach science?

The first amendment of the U.S. Constitution separates science and religion.  (Don’t get into arguments about wording.  That is how it has been interpreted.)   You cannot legally teach religion in state schools, at least not in biology and other science classes.  That was the issue in Arkansas and Dover.  (I am not talking about current affairs or like courses.)  But now ask yourself.  If “God exists” is a religious claim (and it surely is), why then is “God does not exist” not a religious claim?  And if Creationism implies God exists and cannot therefore be taught, why then should science which implies God does not exist be taught?

Don’t get me wrong.  I don’t want science removed from schools.  I want an answer to my question, one which comes up because of the dictates of the Constitution.

Here’s your answer, Dr. Ruse.  It is indeed illegal, as it should be, to teach in the public schools that evolution—or science in general—implies that “God does not exist.” (I believe that this is a reasonable conclusion from science, which implies that certain types of Gods do not exist, but I never mention it in class.) But teaching science is not the same thing as explicitly teaching atheism.  If students want to draw a conclusion from the palpable facts about the world, so be it.  The purpose of science classes is to teach science, not religion or anti-religion, but it’s not our place, as teachers, to prevent students from thinking outside of class. Some students may become atheists after learning about evolution, while others may simply, like BioLogos, incorporate the science into their existing faith.  Not everyone agrees with the proposition that science implies that God doesn’t exist.  But even if they did, that’s no reason to kick science out of the public schools.  Atheism is the notion that there’s no evidence for the existence of God.  That’s not the same thing as science.

Is the teaching of medicine illegal because it contravenes the tenets of Christian Science?  Is the teaching of American history illegal because it contravenes the tenets of Mormonism? The facts are the facts, and we teach them as best we can.  After we do our duty as teachers, and expose students to the facts and to the ways that we ascertain the facts, let those students conclude what they may.  That is, after all, what education is all about.

I don’t know anyone save a creationist who can pack as much stupid into a 1200-word piece as Ruse did in his essay. It’s amazing to think that at one time people took him seriously as a philosopher.

Tonsorial discrimination

December 22, 2010 • 1:29 pm

I just got my holiday haircut at the usual place: a unisex “salon.”  I got into the chair, and about two minutes later a woman got into the adjacent chair.  Like me, she had a regular haircut.  She didn’t have anything fancy done, nor did she purchase any product.  In fact, she was done right before me, and paid right in front of me.  She spent almost exactly as much time under the clippers as I did.

My haircut was $20.  Hers was $32.

1.  Is it normal for women to pay more for the same coupage, even if it takes the same amount of time?

2. If so, what could possibly justify the price differential?

3.  If the answer to (1) is “yes,” isn’t that discrimination against women?
