Iraq reportedly deleting evolution from the biology curriculum

August 27, 2017 • 12:45 pm

After Turkey just removed evolution from the secondary-school science curriculum, we get a report (as of yet unconfirmed) that the same is happening in Iraq. On his website Primate’s Progress, Paul Braterman gives a link to a rather scattered page on The Medium in which Abdulrahman Al Makhzomy reports that Iraq is dropping evolution from its high-school curriculum.  Al Makhzomy gives an August 16 photo of the sixth-grade biology text (apparently in Arabic) and notes that evolution is now missing, and it used to be there. (Translations welcome.)

Well, I don’t understand Arabic, and I’ll take Al Makhzhomy’s word for it, as he links to a Facebook page which is said to confirm his report.

 

Islamic countries have proven resistant to teaching evolution since the Qur’an explicitly gives a creation story in which humans are initially created from dirt, and the Qur’an is read literally far more often than is the Bible. Sometimes Islamic countries are okay with accepting evolution of other species, but human exceptionalism often reigns. Once again we see a conflict between faith and fact. If they’re putting it this way, and we know evolution is true, then Islam—or at least its claim of creation, which is often taken literally—is false.

 

No, the U.S. is not becoming Nazi Germany

August 27, 2017 • 11:45 am

Right now I’m reading a book recommended a while back by a commenter, The End of the Holocaust by Alvin H. Rosenfeld. Although I’m only about 40% of the way through, Rosenfeld’s thesis is clear: the presentation of the Holocaust in popular books and movies (one example is “Schindler’s List”) has diluted the memory of that horrific episode, minimizing its brutality and, in a particularly American twist, attempted to find some good in it so that we needn’t be totally dolorous about the whole thing. In “Schindler’s List”, for example, Rosenfeld claims that the Jewish victims—those who were tortured and gassed—were largely in the background, relegated there by a “demon versus angel” narrative involving concentration camp head Amon Göth on one hand and a Christian “savior”, Oscar Schindler, on the other.

The movie ends with a note of joy and redemption, in a genuine clip where the Jews who Schindler saved parade by his grave, each leaving a stone on his tomb. To Rosenfeld, this sanitizes the Holocaust by diminishing its lesson, which is basically that there was hardly anything to find admirable in people’s behavior (e.g., far more people betrayed Jews than saved them). Rosenfeld gives more examples, and I’m looking forward to the next two chapters, which deal with how Anne Frank’s story has been coopted and changed by its popularity. Rosenfeld appears to see in the Holocaust an unredeemed horror, and decries those who, like Ronald Reagan, use the word as a metaphor for something like legal abortion.

This came to mind when I did my sporadical perusal of the dreaded dreadful Huffington Post (now “HuffPost”), and saw on the front page two pieces implying that Trump is like Hitler and that America is in danger of becoming like Nazi Germany as the alt-right proliferates. (Click on the screenshots to go to the articles.) I see both pieces as crying wolf. Trump is odious and a complete disaster as President, but there’s no way he’s going to set up concentration camps in this country. And we’ve moved on since World War II, hopefully learning that bigotry combined with violence has no place in a democracy.

The headline of the first piece implies that Trump is endorsing camps like Auschwitz or Dachau, but the text shows something quite different:

The text starts out like this:

President Donald Trump’s pardon of former Arizona sheriff Joe Arpaio amounts to an endorsement of the idea of concentration camps, says a journalist who has reported on the global history of the deadly facilities.

Arpaio referred to his own county jail as a “concentration camp.” For over two decades, he operated “Tent City,” where detainees were kept in brutal conditions, including temperatures soaring well above 100 degrees Farenheit. They were also forced to work on chain gangs and to wear pink undergarments as a form of humiliation. Arpaio was convicted in July of criminal contempt for ignoring a court order prohibiting the detention of people based on mere suspicions about their legal status.

In an email to HuffPost Saturday, Andrea Pitzer, the author of One Long Night: A Global History of Concentration Camps, defined a concentration camp as a “mass civilian detention outside the standard legal process, usually on the basis of race, ethnicity, or political activity.” While Pitzer said Tent City was a prison technically constructed to hold those convicted by law, it bore familiar elements to a concentration camp, including “brutal dehuminization.” [sic]

Well, not only was the Tent Camp not a concentration camp by Pitzer’s own estimation, it still “bore familiar elements to a concentration camp.” And Trump didn’t endorse the idea of them; he pardoned Joe Arpaio. I’m not sure, in fact, that Trump has said anything about those camps, yet PuffHo implies that by pardoning Arpaio, he endorses them. This is smearing someone by association, and Trump doesn’t need more smearing since he smears himself constantly.

I’ve objected to these camps before—in fact, just yesterday—as brutal and inhumane, and criticized Trump for pardoning the bigoted Arpaio. (Do I really need to keep issuing these disclaimers?)  But these tent camps weren’t Auschwitz or Bergen-Belsen. Inmates were often given dire food, but they weren’t starved, tatooed, worked to death, or gassed. To imply that Trump endorsed Nazi camps—and make no mistake about it, for that’s what the headline implies—is to lie. Look, we’ve got enough problems with Trump; we don’t need to distort headlines to make him look worse than he is. This is part of the Manichean view of politics that Leftist rags like HuffPo hold.

Here’s another one:

What detail did the Holocaust survivor notice that made him think that “it’s happening now”? (“It” refers to the Holocaust.) It is the image of the tee shirt worn by this man, an alt-righter identified in the caption:

REUTERS/Justin Ide

Jack Rosenthal, a Romanian Holocaust survivor, managed to live through internment as a child in both Auschwitz and Buchenwald, and is still rightfully traumatized at the horror—traumatized in a way that nobody who just watches “Schindler’s List” can ever be. He identifies the tee shirt:

The white supremacist’s T-shirt was the first thing Rosenthal saw. On the shirt was a picture of Corneliu Zelea Codreanu, a pre-WWII leader of the Romanian fascist Legion of Saint Michael the Archangel and the Iron Guard political party, which were both linked to the Nazi party.

Codreanu was the face behind pogroms in Romania. The large-scale violent riots killed tens of thousands of Romanian Jews during the 1930s leading up to the Holocaust.

“I recognized the name right away,” Rosenthal said. “You see something like this, you know, it brings back memories and I’m concerned about what could happen in this country,” he said.

He adds, “After I was liberated, I thought to myself the world has learned what terrible traces hate can bring to humanity,” he said. “And now this gives me a depressing feeling because it’s happening again, and it’s happening now.”

Well, no, it’s not. We have a more alt-right that’s become more vocal since Trump was elected, and we have a President who calls out bigots only reluctantly, and as a form of spin control. But seriously, we are not on the verge of becoming Nazi Germany, and only someone driven nuts by Trump (as HuffPo has been) could think that. Yes, the U.S. has had our own bad times, wrongly interning Japanese-Americans in camps during World War II, but even those weren’t remotely similar tothe Lagers.  And even that couldn’t happen again. Yes, you can cry wolf and say it’s on the horizon, but I’d bet money that we’re not going to have government-run concentrations camps under Trump, or that the Nazi Party is coming back big time. The alt-right and white supremacists may be more vocal under Trump, but they’re universally despised, even by Republicans, and they’ll never have significant power.

We have enough problems dealing with a clueless, narcissistic President and a Republican Congress without having to call them Nazis, or trumpet that Trump approves of concentration camps. Let’s at least have a grasp on reality.

Is identity politics ruining the Left?

August 27, 2017 • 9:45 am

You may have asked yourself, as I have, “So what’s the problem with identity politics? After all, there are marginalized groups in the U.S. and U.K., bigotry is still with us, and why shouldn’t people belonging to those groups agitate to get the rights and treatment they deserve? What were the feminist and civil-rights movements of the Fifties and Sixties besides identity politics?”

That’s a good question, and one that Mark Lilla takes up in two places: in an essay in the Chronicle of Higher Education called “How colleges are strangling liberalism” (this is an excerpt from his new book The Once and Future Liberal: After Identity Politics), and in an interview with New Yorker editor David Remnick, “Mark Lilla on his critique of identity politics.” Lilla is a professor of humanities at Columbia University (he was once at the University of Chicago), “specializes in intellectual history, with a particular focus on Western political and religious thought”, and identifies as a “liberal Democrat” and a “centrist liberal.”

In the New Yorker interview Lilla defines identity politics and also fingers its big problem:

Now, you can say that people think of themselves as Italians or Jews or Germans, and then they become a kind of interest group. We’ve had interest-group politics before. But there’s a kind of essentialism to identity politics, where it means going out into the democratic space, where you’re struggling for power and using identity as an appeal for other people to vote for your side. And I think Bannon’s completely right, and I’ll stand by what I said: that it works for their side and it doesn’t work for our side, for all kinds of reasons. Now, that is not to say that we don’t talk about identity. To understand any social problem in this country, you have to understand identity. And we’re more aware of that than ever, and that’s been a very good thing. But, to address those problems with politics, we have to abandon the rhetoric of difference, in order to appeal to what we share, so that people who don’t share this identity somehow can have a stake, and feel something that other people are experiencing.

In other words—and this is what Lilla emphasizes in the Chronicle review—identity politics so fragments the populace, in particular the Left, that they lose understanding of what’s good for society as a whole, concentrating on what’s good for their identity group—in fact, not even that, but concentrating on what’s good for them as individuals. This not only prevents the Left from political success, claims Lilla, but heartens the Trump administration. As Remnick notes (who isn’t largely on board with Lilla’s views), “There is a quote recently that Steve Bannon, of all people, delivered: ‘The Democrats, the longer they talk about identity politics, I’ve got ’em. I want them to talk about racism every day. If the left is focussed on race and identity, and we go with economic nationalism, we can crush the Democrats.’”

Lilla also blames identity politics for the defeat of Hillary Clinton. Part of his exchange with Remnick:

Lilla: . . . But, when we go out on the stump, it makes no sense to call out to various groups, as Hillary Clinton did, and inevitably leave people out. She would list the groups that liberal Democrats care about today: African-Americans, gays and lesbians, women. One out of every four Americans is evangelical. Thirty-seven per cent of Americans live in the South. Seventeen per cent, as many as there are, of African-Americans in this country live in rural areas. There are different ways in which people think of themselves, right? And those people did not feel called out to.

Remnick: Why do you think they felt called out to by Barack Obama and not by Hillary Clinton? What was the key difference there?

Lilla: Precisely because Obama did not list groups. Because he talked about “we.” He didn’t always finish his sentences—he would say, “That’s not who we are,” and wouldn’t quite tell us who we are. But he understood that. Both Obama and [Bill] Clinton understood that playing identity politics in electoral politics is a disaster for the liberal side.

But what about the notion that we’re throwing those marginalized people under the bus by appealing to a greater unity while ignoring their “identity issues”? Here’s the exchange about that.

Remnick: Unless I misread your book, you seem to say that, in the interest of winning—and politics is about power, ultimately—the Democratic side ought to think about abandoning certain issues, certain kinds of rhetoric, in order to win. But abandoning certain things like full-throated opposition to bathroom bills will mean that certain people—transgender people, some of the most vulnerable people in our society—will get hurt. How does a party go about sacrificing people on the altar of the general good?

Lilla: Well my main point is this, and I want to get this across: we cannot do anything for these groups we care about if we do not hold power. It is just talk. Therefore, our rhetoric in campaigning must be focussed on winning, so then we can help these people. An election is not about self-expression. It’s not a time to display everything we believe about everything. It’s a contest. And once you hold power, then you can do the things you want to do. Your rhetoric has to be mobilizing, and it’s got to mobilize—

. . . if we want to make people more tolerant, the psychology of that is very complicated. What we do know—and psychologists study these sorts of things—if you call someone a racist, they completely shut down. You’re not persuading, you’re not building a bridge to that person. And while it’s satisfying to speak the full truth about something, and I understand that urge, if you’re trying to persuade people and move them a little toward your position, you’ve got to find common ground. And that’s very hard to take for people who are in movements, and feel frustrated that things aren’t going their way.

So Lilla’s view is that “movement politics”—a unified push by different groups—is the only way for liberals to get power, and once that power is seized, then we can concentrate on the issues of specific groups.  Now I’m not sure I’m completely on board with that view, but there’s no doubt that the Right has been heartened by identity politics. Just look at Breitbart, The Daily Wire, or any number of right-wing sites, which daily publish articles on “P.C. [politically correct] craziness.” It makes the Left look petty, embroiled in trivial problems like cultural appropriation and bowdlerizing literature, while what we need is to get political power back from a group with a deeply regressive agenda.

In the Chronicle of Higher Education piece, Lilla of course concentrates on the universities’ responsibility for the fragmentation of the Left, and I think we do bear some of that. Humanities courses reinforce identity politics, and these students, particularly from elite universities, are the ones who will shape the next generation of Leftist politics. Again, Lilla emphasizes the dangers of this fragmentation:

Identity politics on the left was at first about large classes of people — African-Americans, women, gays — seeking to redress major historical wrongs by mobilizing and then working through our political institutions to secure their rights. But by the 1980s it had given way to a pseudo-politics of self-regard and increasingly narrow and exclusionary self-definition that is now cultivated in our colleges and universities. The main result has been to turn young people back onto themselves, rather than turning them outward toward the wider world they share with others. It has left them unprepared to think about the common good in non-identity terms and what must be done practically to secure it — especially the hard and unglamorous task of persuading people very different from themselves to join a common effort. Every advance of liberal identity consciousness has marked a retreat of effective liberal political consciousness.

Campus politics bears a good deal of the blame. Up until the 1960s, those active in liberal and progressive politics were drawn largely from the working class or farm communities, and were formed in local political clubs or on shop floors. Today’s activists and leaders are formed almost exclusively at colleges and universities, as are members of the mainly liberal professions of law, journalism, and education. Liberal political education, such as it is, now takes place on campuses that, especially at the elite level, are largely detached socially and geographically from the rest of the country. This is not likely to change. Which means that liberalism’s prospects will depend in no small measure on what happens in our institutions of higher education.

What’s strange about this essay, though, is Lilla’s take on my own cohort: the “’60s generation”, now in charge with teaching in the universities, and presumably of infecting students with identitarianism.

Lilla credits that group with having learned that “movement politics” (the cooperation of different groups to get power) was “the only mode of engagement that actually changes things”, but curiously, adds “which was once true but no longer is.” If it’s no longer true, and identity politics does change things, why is he writing this essay? Perhaps I misunderstand him. He adds that that generation also learned something that promoted current identity politics: “political activity must have some meaning for the self, making compromise seem a self-betrayal (which renders ordinary politics impossible).” I’m not sure if he’s right here: if Sixties politics was effective in promoting civil rights, gay rights, and women’s rights, which it was, how did we internalize lessons that, says Lilla, aren’t effective in changing a more right-wing government?

I’ll give a few more quotes from Lilla’s article (yes, this is getting long, but we’re supposed to have a higher attention span than The Kids). Here’s his view of how college transforms an entering young woman into an identitarian. This, to me, seems accurate (my emphasis):

Imagine a young student entering such an environment today — not your average student pursuing a career, but a recognizable campus type drawn to political questions. She is at the age when the quest for meaning begins and in a place where her curiosity could be directed outward toward the larger world she will have to find a place in. Instead, she is encouraged to plumb mainly herself, which seems an easier exercise. (Little does she know. …) She will first be taught that understanding herself depends on exploring the different aspects of her identity, something she now discovers she has. An identity which, she also learns, has already been largely shaped for her by various social and political forces. This is an important lesson, from which she is likely to draw the conclusion that the aim of education is not to progressively become a self — the task of a lifetime, Kierkegaard thought — through engagement with the wider world. Rather, one engages with the world and particularly politics for the limited aim of understanding and affirming what one already is.

And so she begins. She takes classes where she reads histories of the movements related to whatever she determines her identity to be, and reads authors who share that identity. (Given that this is also an age of sexual exploration, gender studies will hold a particular attraction.) In these courses she also discovers a surprising and heartening fact: that although she may come from a comfortable, middle-class background, her identity confers on her the status of one of history’s victims. This discovery may then inspire her to join a campus group that engages in movement work. The line between self-analysis and political action is now fully blurred. Her political interest will be genuine but circumscribed by the confines of her self-definition. Issues that penetrate those confines now take on looming importance and her position on them quickly becomes nonnegotiable; those issues that don’t touch on her identity (economics, war and peace) are hardly perceived.

The more our student gets into the campus identity mind-set, the more distrustful she will become of the word we, a term her professors have told her is a universalist ruse used to cover up group differences and maintain the dominance of the privileged. And if she gets deeper into “identity theory” she’ll even start to question the reality of the groups to which she thinks she belongs.

There are few thing more empowering and heartening than discovering that you’re a victim of sorts, for now you have the privilege to tell other people to be quiet because of your superior “lived experience,” and you suddenly become special, something that shouldn’t be underrated. A Muslim student with a hijab is special because she can claim she’s oppressed because of her identity, while a Muslim woman with uncovered hair has no such status. I have seen these claims repeatedly. (I add the usual but unnecessary caveat that bigotry against Muslim individuals or members of any minority is reprehensible.) But the point—or rather Lilla’s point—is that this specialness defuses any desire to work with others to do things like get a damn Democrat in the White House.

Lilla (again, my emphasis):

The more obsessed with personal identity campus liberals become, the less willing they are to engage in reasoned political debate. Over the past decade a new, and very revealing, locution has drifted from our universities into the media mainstream: Speaking as an X … This is not an anodyne phrase. It tells the listener that I am speaking from a privileged position on this matter. It sets up a wall against questions, which by definition come from a non-X perspective. And it turns the encounter into a power relation: The winner of the argument will be whoever has invoked the morally superior identity and expressed the most outrage at being questioned.

So classroom conversations that once might have begun, I think A, and here is my argument, now take the form, Speaking as an X, I am offended that you claim B. This makes perfect sense if you believe that identity determines everything. It means that there is no impartial space for dialogue. White men have one “epistemology,” black women have another. So what remains to be said?

What replaces argument, then, is taboo. At times our more privileged campuses can seem stuck in the world of archaic religion. Only those with an approved identity status are, like shamans, allowed to speak on certain matters. Particular groups are given temporary totemic significance. Scapegoats are duly designated and run off campus in a purging ritual. Propositions become pure or impure, not true or false. And not only propositions but simple words. Left identitarians who think of themselves as radical creatures, contesting this and transgressing that, have become like buttoned-up schoolmarms when it comes to the English language, parsing every conversation for immodest locutions and rapping the knuckles of those who inadvertently use them.

Having spent my whole life after 1967 in college (indeed, I liked it so much that I vowed, one way or another, that I’d never leave—and haven’t), Lilla’s words here seem accurate. The fragmentation of the Left into competing oppressed groups has prevented them from working together—something we see among educated atheists as well. And I think that Lilla’s comments on identitarianism defusing movement politics also has some merit. When, for example, I hear enraged students indicting Israel for various “apartheid” crimes (and ignoring the Palestinian attacks on civilians, as well as the own religiously-based oppression of their citizens), I don’t see students committed to solving this nearly intractable problem. Rather, they want to shout slogans, vent their rage, some want to flaunt their virtue, and none of this is even aimed at addressing the nearly intractable problem—unless you mean by that getting rid of the state of Israel.

Now most of the “identity” causes are meritorious: there’s still racism and sexism in this country, and that needs to go. But I don’t see it going so long as each group denies the other a contribution to the conversation—something that’s impossible if you claim full possession of the truth and the right to speak based on your identity. I may sound like an old guy here (and I am), but I remember that when marching in civil rights demonstrations, or discussing those issues, or fighting against the war, there were few arguments about which group had the hegemony of power and right to speak. Rather, I remember a wonderful sense of common purpose: we were all in this together, and we were going to change the world. Seriously—we really thought that! Well, we didn’t, of course, but that unanimity did help stop the Vietnam War and secure rights for women and blacks (gay rights weren’t yet on the table when I was a student).

To close, I’ll reprise Lilla’s thesis once again from the Chronicle piece:

Conservatives are right: Our colleges, from bottom to top, are mainly run by liberals, and teaching has a liberal tilt. But they are wrong to infer that students are therefore being turned into an effective left-wing political force. The liberal pedagogy of our time, focused as it is on identity, is actually a depoliticizing force. It has made our children more tolerant of others than certainly my generation was, which is a very good thing. But by undermining the universal democratic we on which solidarity can be built, duty instilled, and action inspired, it is unmaking rather than making citizens. In the end this approach just strengthens all the atomizing forces that dominate our age.

Remnick, as I said, is pretty critical of Lilla, and seems himself somewhat of a Control Leftist in his interview (this is reflected in the New Yorker‘s slant on politics). So, if you have time, read that interview, and also the Chronicle piece, and weigh in below. Weigh in even if you haven’t had time to read either, as I’ve given, I think, a sufficient precis of Lilla’s arguments.

Readers’ wildlife photos

August 27, 2017 • 7:30 am

Bruce Lyon of the University of California at Santa Cruz favors us with some amazing whale-watching photos. His notes are indented.

A few days ago I went whale watching with my favorite company, Sanctuary Cruises, based in Moss Landing, California. There are so many whales in Monterey Bay right now that it seems like whale soup—everywhere we looked there were humpback whales (Megaptera novaeangliae). They are spending the summer in the bay feeding on the rich food supply, which this year seems to be anchovy.

Below: A pink-footed shearwater (Puffinus creatopus) flies by a surfacing whale.

The whales were very active and we saw many animals breaching (leaping mostly out of the water); but they were always in the distance and never close. We did come across a couple of cooperative tail-slappers and this may be some sort of display that serves a similar function to breaching—making a giant splash plus a loud noise that travels a long distance under water.

Below: A tail slapper sticks its rear end high above the water and then whacks the water with its tail, producing a mighty splash. The evidence that these slapping type displays (breaching, trail slaps and pectoral fin slaps) are a form of communication comes from observations that social context predicts their occurrence. One study found that breaches were more likely to occur by lone males and other singletons, while slaps were found in groups of whales. What exactly is being communicated is unclear.

Below: As impressive these displays are, it was the lunge feeding that stole the show on this trip. In lunge feeding, the whales dive down under a dense food aggregation that is near the surface, then swim upwards toward the food and just as they surface they open their mouth wide to take in a huge volume of water full of krill or fish. Humpbacks, like other rorqual whales, have pleated or furrowed throats and bellies that can expand like a balloon, which allows the animal to engulf a massive amount of water in a single gulp (referred to as the ‘big gulp’ in a couple of scientific papers). Lunge feeding is often done in groups and the whales all pop up at the surface at the same time in a spectacular performance. In the lunge below, five whales surfaced at the same time right beside our boat.

Below: The tour company’s naturalist, Chase Dekker, sometimes films whales with a drone and his videos give a pretty unique bird’s eye perspective on some of these behaviors. Chase’s video below was shot a couple of weeks ago on a different trip, and it provides a lovely view of a couple lunge-feeding humpbacks. Note that the ‘bait ball’ of anchovies remains in a dense aggregation near the surface, which is why lunge feeding works. It is also interesting to see that these massive whales can almost turn on a dime, helpful for following (and perhaps herding) the fish.

If you want to hear the accompanying music, which isn’t bad, be sure to turn up the volume:

Below: I find it challenging to photographing lunge feeding because it is not always easy to predict exactly where the whales will surface and, when they do, they are only above the water for a few seconds. Fortunately other animals sometimes provide clues as to where a lunge feed is likely to occur. California sea lions (Zalophus californianus) often join in the fun and typically form sudden dense congregations close to where the whales will pop up. When we saw these sea lions going crazy we knew it was time to get the cameras ready.

Below: The whales often surface very close to the sea lions, which have to scatter. Here a sea lion seems to be trying to stay out of the way. Several lunge feeds occurred right at the boat (≤ 20 feet). Of course, that was when I did not have my wide-angle lens on the camera so I could only capture part of the action, as is the case with this photo. It is quite something to see these animals so close, especially when several suddenly pop up out of the water together.

Below: Birds like gulls and shearwaters can also be helpful sentries. Since they can see the bait balls from the air, they often hover above where the whales are about to surface and then feast on anchovies forced to the surface. This particular group seems to be only gulls. In one memorable lunge feed, the pressure wave from the surfacing whales blasted a cloud of anchovies into the air!

Below: This time I was successful at predicting where the animals would come up. This photo was taken with a normal lens (so no real magnification) and several times they were even closer than this. Note the interesting shape of the blowhole on the second whale from the right. At one point we had several whales feeding right at the boat for about an hour, often too close to photograph. This apparently happened on several previous trips as well and the boat crew suggested that the swarm of anchovies might be trying to take refuge under the boat, and the whales then follow them.

Below: The enormous amount of water engulfed in a lunge greatly extends the throat and belly. In part this is made possible by the expanding furrows, which can be seen in the photos (rorqual comes from a Norwegian word meaning furrow whale). The biomechanical aspects of lunge feeding are complex and intriguing and have been studied in some detail recently by Jeremy Goldbogen (Stanford) and various colleagues. They report in one paper that the volume of water taken in by fin whales (Balaenoptera physalus) in a single lunge feeding weighs more than the whale itself. This is not an easy task and apparently there are several morphological features that help make this remarkable feat possible. One of the more interesting of these is floppy loose tongue that can invert and form a concave sac that accommodates the water on the belly side.

Below: To extract the food from the big gulp, water has to be pushed out of the mouth without the food going with it. This is done by filtering the water through the baleen plates, which are made of keratin, as is our own hair and nails. In the first photo below, a wreath of baleen can be seen on the skinny upper jaw. To me the texture resembles a shoe brush. This sequence of three photos also shows the feeding style of a smaller animal that fed with a technique that seemed like a cross between a breach and lunge feeding; it often came quite high out of the water. These photos were taken a motor drive and span less than a second interval. Comparing the change in jaw positions in the three photos shows that the lower and upper jaw come together surprisingly quickly. A few lucky escaping anchovy can also be seen, particularly in the top photo.

Below: I think this is the same animal as the sequence of three above, but showing a different ‘breach-lunge’. This image clearly shows the water being pushed out of the whale in a gush. For orientation, we are looking at the top of the whale’s head and its belly is facing away from us.

Below: Another photo showing a couple of whales with distended bellies and the expanded furrows. The animal on the left is also ‘decorated’ with many dozen whale barnacles (Coronula diadema) on its throat. Each whale barnacle species seems to be specific to one whale species; this one is found only on humpbacks. The barnacles are passive hitchhikers that let the whale do the work of making the water flow over them (by the whale swimming) while they filter feed tiny particles from the water. They are thought mostly to not cause problems for the whales, but extreme infestations might increase drag and make swimming less efficient.

Below: A closer view of some barnacles on the very front of a whale’s snout. Like many barnacles, these appear to have planktotrophic (free swimming) larvae. However, other barnacles live on solid substrates that don’t move, like rocks or pilings. It is interesting to think about the difficulties that whale barnacle larvae face in finding their moving target of a host.

 

Sunday: Hili dialogue

It’s Ceiling Cat’s Day: render under Him what is His (cream, mice, etc.) on this Day of August 27, 2017. It’s National Burger Day, celebrating the most iconic indigenous food in America. As Foodimentary notes, “The oldest fast food restaurant in the world is the White Castle franchise, which opened in 1921.” (Their tiny hamburgers are called “sliders.”) In Texas, it’s a legal state holiday (though people don’t work on Sunday anyway): Lyndon Baines Johnson Day , celebrating his birthday (be sure to read Robert Caro’s multivolume biography of LBJ: the best modern biography of anyone).

On this day in 410, the three day sacking of Rome by the Visigoths came to an end. On August 27, 1859, petroleum was discovered in Titusville, Pennsylvania, leading to the construction of the world’s first commercially successful oil well. Here it is, the famous Drake Well:

On this day in 1883, the volcano Krakatoa finally exploded for good, destroying the island. Wikipedia notes this as well for August 27, 1927: “Five Canadian women file a petition to the Supreme Court of Canada, asking, “Does the word ‘Persons’ in Section 24 of the British North America Act, 1867, include female persons?” Surprisingly the judgment against the “Famous Five” was “no”, though it was overturned two years later by the British Privy Council. On August 27, 1979, a bomb set by the IRA killed retired British Admiral Louis Mountbatten (also former Viceroy of India during Partition), as well as three others, while they were boating in Sligo, Ireland.  And on this day in 2003, Mars made its closest approach to Earth in 60,000 years: 34,646,418 miles (55,758,005 km). It almost hit us!

Notables born on this day include Charles G. Dawes (1865), Theodore Dreiser (1871), Man Ray (1890), C. S. Forester (1899), Don Bradman (1908; greatest cricket batsman of all time), Lyndon B. Johnson (also 1908), William Least-Heat Moon (1939), Daryl Dragon (1942) and Barbara Bach (1947). Those who died on this day include Titian (1576), Frank Harris (1931), Ernest Lawrence (1958), W. E. B. DuBois (1963), Gracie Allen (1964), Le Corbusier (1965), Haile Selassie (1975), Louis Mountbatten (1979; see above) and Stevie Ray Vaughan (1990). Meanwhile in Dobrzyn, Hili is affronted at Cyrus’s dilatory behavior:

Hili: Cyrus stayed on the other end of the path.
A: He will come soon.
Hili: Yes, but we have to wait for him.
In Polish:
Hili: Cyrus został na drugim końcu ścieżki.
Ja: Zaraz przyjdzie.
Hili: Tak, ale my musimy na niego czekać.

Meanwhile in Winnipeg, a cut Gus is sitting in “his spot”, one of the round stones on the garden path:

From reader Barry: a tweet from David Attenborough—on cats! Make sure the sound is on:

And two catches by Matthew Cobb. The coloration in this katydid mimics damage by a herbivore: isn’t natural selection amazing?

And a colored butterfly egg; I had no idea these existed:
