Darwin Day at the Dinosaur Discovery Museum: report

February 15, 2015 • 4:11 pm

by Greg Mayer

Jerry has just returned from his Darwin Day activities in Mississippi, and I’m sure we’ll be receiving a report on how things went (including in the culinary department). In the meantime, here’s a report on how things went at the Dinosaur Discovery Museum’s Darwin Day event last weekend.

The museum has one main exhibit hall, having a very large number of dinosaurs (especially theropods); most are high quality reproductions. In the lobby, I set up a temporary exhibit table on the theme of “Highly Evolved Tetrapods”, meaning ones that have lost or rearranged major parts of their skeletons. My table, manned by my son Christian and myself, featured live animals.

The hit of the exhibit was Vivian, an adult ball python (Python regius). Many people, as urged to by our signage, asked to see Vivian’s hind legs.

Vivian-- the star of the show.
Vivian– the star of the show.

Most people (even biologists) don’t know that some extant snakes have vestigial hind limbs, and my son and I have always liked to show them off. Once, when he was in grade school, he told a naturalist at a creationist nature camp (admittedly an odd combination) about the legs on a python they had on exhibit. She demurred, but my son, in good faith (he didn’t know they were creationists) persisted, and offered to show the legs to her. She allowed as she had seen the structures, but that they weren’t legs. He again persisted, stating (correctly) that the leg bones and pelvis were still there, and that they were legs. She could only sputter that they were not legs “in my world view”!

The giant toad (Bufo marinus; called cane toads in Australia, but native from Texas to Argentina) was also quite popular. You can see the large ellipsoid poison glands behind the eye, and the swelling of the body to make swallowing difficult, another defensive attribute. We also had an American toad (Bufo americanus; common throughout most of the eastern United States and Canada) for comparison. Both are good-sized adults.

We also had Slidey, a red-eared slider (Trachemys scripta elegans); we’ve noted before here on WEIT how highly evolved turtles are.

My paleontological colleagues Summer Ostrowski and Chris Noto set up a temporary exhibit featuring small, touchable fossils and a very fine selection of plastic animals.

The plastic animals (all high quality collector-grade pieces) were arranged in correct phylogenetic arrangement. Although you can barely see him under the mammoth’s chin, humanity is represented by a 3D print of Charles Darwin as depicted in the sitting statue of him at the Natural History Museum in London.

Chris and I also gave lectures in the museum’s downstairs class room, on “How Evolution Works” (me) and “What the Fossil Record Tells Us about Evolution”. Nick Wiersum, Curator of Education, led special activities in the main exhibit hall.

I think the event was quite successful, with events suitable for kids, students, and adults. There was a good crowd, from kids through adults, with steady numbers the whole day, and lots of good questions. The attendees included WEIT readers, some who came from Milwaukee and Evanston– thanks so much for the support, and it was good to meet you!

The further adventures of Harry

February 15, 2015 • 3:45 pm

by Matthew Cobb

Regular readers will know that I have become the staff of a small kitten called Harry, who is bitey and scratchy and generally excitable, except when he’s not all floppy and purry and asleep. On Saturday, Harry decided to help me with marking (aka grading) second year university exams. These were short answers about Xiphosurida (aka horseshoe crabs—in keeping with the law of nomenclature, these aren’t crabs and don’t look like a horseshoe, plus they aren’t ‘living fossils’)—and about the advantages of being bilaterally symmetrical. Here he is, as I told Tw*tter (he loves my marking pens):

However, life isn’t all a bed of roses. Harry is a very pesky kitten who loves chasing the two grown-up cats who we serve, Ollie and Pepper (Ollie is the one who scratched Jerry’s nose a few years back). Today Ollie decided he was having no more of it, and when Harry came for him again, there was a stand-off. This was the first real fight they’ve had (though there’s been plenty of growling and hissing from Ollie and especially Pepper, who really does not like the kittenish behaviour of the kitten).

No one got hurt, and it looks worse than it was, but a bit of fur (mainly Harry’s) flew… I decided to leave them to and to take photos, just like, when my children were little I’d occasionally take vids and photos of them crying or having a tantrum, so I’d remember that life isn’t always happy… These two cats were both pretty cross!

Putin has bamboozled the West

February 15, 2015 • 2:51 pm

There is no doubt in anyone’s mind that Putin is encouraging and arming (and even contributing fighters to) the Ukranian pro-Russian separatists. His goal is either to simply absorb Ukraine in its entirety, or to keep it free from any ties to the West, so that it stays within Russia’s “sphere of influence”. Indeed, there are some reports that Russian armaments and soldiers are directly helping the rebels as the tenuous cease-fire in Eastern Ukraine threatens to fall apart.

Putin is a thug, but he’s a clever one. He waffles constantly on the involvement of Russia in this battle, goes back and forth on what he wants with the region, and generally keeps the West off balance. He won’t talk straight. Though that’s hardly new, it contrasts with the West, which has clearly said what it wants and has laid out its own (ineffective) plan of action. When we say we won’t give lethal weapons to Ukraine, we don’t.

The problem is that Putin is willing to use arms—Russian arms—to win this battle, and the West is afraid to even give arms to Ukraine so they can fight off the Russians and rebels. The reason, of course, is that we’re afraid of escalating a conflict into something even more horrible, something that might draw Russia into a wider war—and even involve nuclear weapons.  So Putin blithely goes ahead, knowing that we’re puzzled and afraid. Yes, the sanctions are squeezing Russia, but they’re not doing anything to stop him.

On a smaller scale, this is like Hitler taking over the Sudetenland. Nobody dared stand up against him for fear of war. And so he blithely marched through one area after another—until he got to Poland. And then there was war. How far will Putin go before the West stops waffling and dithering? A long way, I think.

NPR jumps the shark on atheism and the North Carolina murders; presents Reza Aslan as their only “expert”

February 15, 2015 • 1:49 pm

I’ve had it with National Public Radio.  Their incessant coddling of faith and indictments of atheism, without giving nonbelievers a chance to present their arguments, is reprehensible. And the nadir occurred this morning when NPR carried a four-minute story on Weekend Edition “analyzing” the murders of three Muslims in Chapel Hill, North Carolina. Click on the screenshot below to go to the site and hear NPR embarrass itself. (There’s also a transcript of the piece.) Who was the one “expert” chosen to explain the killings? Our old friend, the religious apologist Reza Aslan.

The title at the website, shown below, tells it all.

Screen Shot 2015-02-15 at 9.07.53 AM

Well, yes, maybe some see “extreme anti-theism” as a motive, but others see guns, others mental illness, others a parking dispute.  It’s all a muddle at this point, and may remain so forever. Why, do you suppose, did NPR concentrate on “anti-theism”? And who is “some”. Well, “some” turns out to be “one”: Aslan!

Here’s part of the transcript:

Religion scholar Reza Aslan says ordinary atheists just don’t believe in God. Hicks, Aslan says, was an anti-theist.

“An anti-theist is a relatively new identity, and it’s more than just sort of a refusal to believe in gods or spirituality; it’s a sometimes virulent opposition to the very concept of belief,” Aslan says.

“Virulent”? Why not “passionate”? Here are the two most relevant definitions of “virulent’ from the Oxford English dictionary, showing that the word definitely has a pejorative tone:

Screen Shot 2015-02-15 at 1.40.25 PM Screen Shot 2015-02-15 at 1.40.37 PM

More:

The anti-theists have their own heroes; people like the outspoken writer Richard Dawkins, who appears often on HBO’s Real Time with Bill Maher condemning religion generally and Islam in particular.

“I mean these people have a holy book that tells them to kill infidels,” Dawkins once said on the show.

In fact, what Dawkins said above is the truth. Why does NPR present it as if it’s some bigoted interpretation of the Qur’an? The piece continues:

Reza Aslan says the anti-theists are few in number. But just as mainstream Muslims must confront the extremists in their communities, Aslan says, it’s time for mainstream atheists to do the same.

“To recognize that there is a small fringe element that has a belief system predicated on the inherent nature of religion as insidious, as needing to be removed from society,” he says.

Aslan is, pardon my French, a mushbrain. “Anti-theism” is not a “relatively new identity”: just go read Mencken or Robert G. Ingersoll (who wrote in the 19th century), Madelyn Murray O’Hair, or any number of the earlier “atheists” in Hitchens’s estimable book The Portable Atheist. The reasons atheists became “anti-theists” is because it simply became less dangerous to say what you thought about religion, not that some nonbelievers recently decided that religion was harmful.

There is in fact no strict demarcation between “atheists” and “anti-theists”.  We have atheists who don’t believe but see religion as either beneficial or benign, atheists who see religion as generally harmful or worthless, but aren’t activists, and we see atheists who see religion as harmful and are activists. And there are all gradations of this. None of them, at least in America, have been accused of violence—until now. Aslan, who loves to draw this distinction, now can’t resist putting it into practice by connecting it to the Chapel Hill murders.  He is a vile, unctuous and disingenuous opportunist, who loves the limelight far more than he hates atheists.

The fact is that one can make a good case that religion is harmful, even if only that it deludes people about their future, and to argue such a view doesn’t make one some kind of extremist or fringe radical whose views lead ineluctably to murder. There are those who, for instance, see belief in the paranormal as harmless, and those who see it as harmful and inimical to a rational worldview. Do we call the former “a-paranormalists” and the latter “anti-paranormalists”? The distinction is drawn for one reason only: to discredit unbelief by making it seem strident, unreasonable, and even a cause of violence.

NPR does quote Asra Nomani, a Muslim writer who says that Muslims shouldn’t use the killings as an excuse to create a “culture of fear”, but that doesn’t stop the show giving its own slant on the crime.

But right now the feeling among Muslim Americans seems to be that the North Carolina killings were clearly a hate crime.

President Obama on Friday released a statement, saying no one in America should be targeted because of who they are or how they worship. That statement followed a decision by the FBI to launch its own hate crime investigation in North Carolina.

Yes, of course many Muslims may see this as a hate crime, but they have their own viewpoint that doesn’t necessarily represent what really happened. Right now there is in fact a “hate crime” investigation that will determine if this act falls under the legal specifications of such a crime. Until that happens, we should reserve judgment. NPR doesn’t want to, and if they were responsible journalists, they’d present an opposing view, both to the notion that “anti-theism” is young and a “small fringe element of atheism”, and to the implication that anti-theism played some role in the killings. Or, if they were truly responsible, they’d stop fanning these flames and just shut up.

How we’d acquaint aliens with our civilization

February 15, 2015 • 12:45 pm

So here’s your task: you can put 115 images on a spacecraft that, in sum, will acquaint any aliens who see them with the nature of our world and our solar system.  How can you possibly do that? There’s so much to tell about: our different cultures, our music, our architecture, our food, our bodies, our science, our technology—and you get just 115 images to convey the whole lot.

Well, that would be enormously fun, I think, and in fact somebody did it. Under the aegis of NASA, a group of people put together those images on the so-called “Golden Record” put aboard the Voyager Spacecraft (there were two, both launched in 1977), in the hope that perhaps someday, after our Earth may be long gone, an advanced civilization could learn about that one brief shining moment known as “life on Earth.”

I find the images incredibly poignant; all 115 are reproduced on imgur, and I’ll put some below. Besides the scenes, there are also greetings, music, and sounds from Earth, which you might peruse on their respective pages. But first a bit about the “Golden Record” from the NASA Voyager site:

Pioneers 10 and 11, which preceded Voyager, both carried small metal plaques identifying their time and place of origin for the benefit of any other spacefarers that might find them in the distant future. With this example before them, NASA placed a more ambitious message aboard Voyager 1 and 2—a kind of time capsule, intended to communicate a story of our world to extraterrestrials. The Voyager message is carried by a phonograph record-a 12-inch gold-plated copper disk containing sounds and images selected to portray the diversity of life and culture on Earth.

The contents of the record were selected for NASA by a committee chaired by Carl Sagan of Cornell University, et. al. Dr. Sagan and his associates assembled 115 images and a variety of natural sounds, such as those made by surf, wind and thunder, birds, whales, and other animals. To this they added musical selections from different cultures and eras, and spoken greetings from Earth-people in fifty-five languages, and printed messages from President Carter and U.N. Secretary General Waldheim. Each record is encased in a protective aluminum jacket, together with a cartridge and a needle. Instructions, in symbolic language, explain the origin of the spacecraft and indicate how the record is to be played. The 115 images are encoded in analog form.

How fun! Imagine the arguments they had about how to best convey our species and what we know.

First, here’s the letter from Jimmy Carter explaining the record:

And my favorite! I believe the extended fingers are part of a Chinese drinking game, but I’m not sure. Imagine aliens puzzling over this one:

bNIVK

Here’s how you can get them (if you can get them):

The definitive work about the Voyager record is “Murmurs of Earth” by Executive Director, Carl Sagan, Technical Director, Frank Drake, Creative Director, Ann Druyan, Producer, Timothy Ferris, Designer, Jon Lomberg, and Greetings Organizer, Linda Salzman. Basically, this book is the story behind the creation of the record, and includes a full list of everything on the record. “Murmurs of Earth”, originally published in 1978, was reissued in 1992 by Warner News Media with a CD-ROM that replicates the Voyager record. Unfortunately, this book is now out of print, but it is worth the effort to try and find a used copy or browse through a library copy.

Finally, after Matthew (who sent me the imgur link) saw this post, he sent me this email:

The photos are both brilliant and bizarre. Just as well nothing will ever read them – what would they make of them? There’s an SF story there.

Indeed! What a great premise! Some alien civilization receives the Golden Record, tries to interpret it, and gets everything wrong! What do they make of Beethoven, or the communal Chinese dinner? Lots of room for laughs.

EDIT by Matthew Cobb – In the first Star Trek film from 1979, the alien space craft is in fact a souped-up version of Voyager, which ‘went through a black hole and ended up on the other side of the galaxy’ where it was encountered by a machine race which gave it the ability to fulfill its destiny (or some such rubbish). Here’s a clip:

Hitchens: Does atheism motivate governments to kill?

February 15, 2015 • 10:57 am

This old question is of course being discussed again now that three Muslims have been murdered in North Carolina by an atheist. It’s not really an question that’s germane to the killing, for, after all, Hicks acted on his own, and we sure don’t have an atheist government. Nevertheless, this is one of the main criticisms leveled at atheists who themselves accuse Christianity, Islam, and other faiths of promoting dreadful behavior. “What about Pol Pot, Stalin, Hitler, and Mao?”, the believers and faitheists say? They perpetrated some of the worst genocides of our time, and they were explicitly atheist governments!

We’ve heard many of the responses, and my view is that yes, atheist governments can certainly do bad things, but usually not explicitly in the name of atheism. In that way they’re unlike the murders and terrorism committed explicitly in the name of faith: the Inquisition, the perfidies of ISIS, the killing of Shiites by Sunnis (and vice versa), the persecution of the Jews, and so on. But what’s important here is not religion per se, I think, but the problem of faith: those governments or movements weren’t operating on Enlightenment values or on the institutionalization of reason, doubt, and considered examination, but rather on unquestioning obedience to an infallible leader and ideology.

I discuss the issue of faith in The Albatross, and say that religion is only one form of misguided faith, though it’s the world’s most pervasive form. The clash between religion versus atheism, is one battle in the war between faith and reason. When I discuss the Lysenko affair, for instance, and describe how a misguided agronomist, supported by Stalin, ruined Soviet genetics and agriculture, there is a definite faith-like element in the whole mess. Stalin was the father, Lysenko his anointed son—here we do have a strong parallel to religion!—and neither could do any wrong. Soviet geneticists even fudged their data so it could conform to Lysenko’s bogus theory that environmental exposure of seedlings to cold would change their genetic constitution. And so, because questioning was prohibited and faith encouraged, in the face of evidence, the Russians lost decades of scientific advances and thousands starved. (The Soviets also killed many of their “blasphemous” scientists who questioned Lysenko, notably Nikolai Vavilov.) Real genetics was denigrated as a Western corruption.

While looking at a YouTube video today, another one, featuring Christopher Hitchens, was called to my attention in the margins. (YouTube, of course, monitors our usage and makes “suggestions” of what we might like. This is one I did like.). Here, in 2007, Hitchens is asked The Question about Pol Pot, Mao, Hitler, and so on.

I’d suggest watching it.  At times Hitch seems to be reaching, trying to blame religion or distortions of religion for these atheist-regime genocides, as when he imputes the aggression of the Japanese in World War II on “ancient ethnic (Buddhist) pseudoconfessional mystical nationalism”.

But then, toward the end, he zeroes in on the real problem: not religion but faith. (I discuss what I mean by “faith” in The Albatross as well, but a short version is “strong belief without sufficient evidence to support that belief, or belief even in the face of the evidence”. I don’t want to argue about that here, as I discuss all the ramifications in my book.) As Hitchens says, these totalitarian societies asked their citizens to “surrender your mind and put your trust in faith.”

As I watched the video, this question came to me, “What would it take to convince people that atheism was responsible for state genocide?” That’s a good question to ask ourselves, too, about the Chapel Hill killings. Before we call it a “hate crime,” or a crime motivated by Hicks’s atheism, we should ask ourselves these questions (and try to think about how we would have answered before the Chapel Hill killings): “What would it take to convince rational people that a murder was caused by atheism?” Or, “How would we decide whether a crime was a ‘hate crime’ motivated by animus toward a religion or ethnic group?”

And then—mirabile dictu!—Hitchens answers that question, at least for whole societies, beginning at 11:44 in the video. His answer redeems the whole discursive 20-minute discussion, and is characteristically eloquent.  (God, I miss that man!) I’ll let you listen to the answer yourself (go to 11:40 or so), but there’s one sentence I will reproduce from Hitchens’s discussion of his ideal: the secular and rational society:

 “If you wanted the transcendent you’d have love and sex and music you wouldn’t need any supernatural permission for any of this nonsense.”

Have a watch:

Note that Hitchens’s “water” seems suspiciously amber-colored. Could it be tainted by Mr. Walker’s amber restorative?

Readers’ wildlife photography

February 15, 2015 • 9:48 am

A while back reader Gregory sent an nice set of pictures of the process of banding and testing the chicks and adults of a Coopers Hawk (Accipiter cooperii) who had nested in his neighborhood. Here is his story and the pictures of the banding (and other bird-related items):

In 2007 and 2008 we had a Coopers Hawk nest in front of our home in Milwaukee. Then, in 2009, they moved their nest a few blocks away. During these years the nest was visited by an ornithologist (and one time, two of them) who climbed up the tree and brought the chicks down for banding and blood draws. One year they used a net and a rescued owl to capture the parents for blood testing, too. (The owl was blind in one eye and as a result is available as an assistant in the capture process… Coopers chicks are prey to owls and the parents freak out, try to chase the one-eyed fellow away, and end up in the net.) [JAC: That’s amazeballs!]
Anyway, I took lots of pictures and there are some I’m sending along… hoping they get through the email system. I was able to hold one of the parents during the process and was amazed at how much heat they radiate. It was an adventure having them on the block. I miss them, although I don’t miss the small bird body parts that littered the sidewalk under their dining trees. 😉

JAC: The young of many predatory birds (including, you may have noticed, the Great Horned Owl) are covered with white down. I wonder why the color? It wouldn’t seem to be cryptic, as white chicks stick out like a sore thumb.  It might just be a developmental constraint, but I doubt it (down doesn’t have to be white!). Perhaps readers have suggestions.

I decided to send three more… One shows the male (I think) just about to have his blood drawn. The other two I include although they are a bit unhappy.  In the second year of the nest in front of our home, the chicks died a week or so after they were banded. We believe it was the result of raccoons, who apparently climbed the tree. I took a photo of one chick, dead, on the sidewalk below the nest.  Then the following year, in the nest a couple blocks away, some of the eggs had died although two chicks were doing fine. I took a photo of one of the dead eggs after the biologist at the scene tossed it out on the boulevard. Sad things happen in the wild.

Sunday: Hili dialogue

February 15, 2015 • 7:38 am

Oy! It was nearly 70ºF (21ºC) in Mississippi yesterday, with lots of sun; it was like spring. But back here in Chicago it’s gray, bleak, and the temperature is in single digits. And I overslept—until 7:30—as I didn’t arrive home until 11 p.m. I am a bad person.

Meanwhile in Dobrzyn, Hili makes her first good joke, and one that works very well in English but not Polish:

Cyrus: Little Miss Moses?
Hili: Nope, Bastet in the basket.

In Polish:
Cyrus: Mojżeszówna?
Hili: Nie, Bastet w koszyku.
