Paul Ryan added briefly to Wikipedia’s “invertebrate” page

January 28, 2017 • 11:30 am

Well, it didn’t last long, but some wag (look up the origins of “wag,” by the way, which is a short version of “waghalter”) committed an Act of Humor on Wikipedia. As reported by SelectAll, which gives a tw**t by Buzzfeed writer Alp Ozcelik, for one brief shining moment an editor put Paul Ryan, Republican Speaker of the US House of Representatives, on the Wikipedia page for “Invertebrate”. Here’s what was up for a brief while, including Ryan in a table of the different groups of invertebrates and the number of species in each group:

On the off chance you don’t get it, invertebrates are animals without spines.

Berkeley chancellor’s statement on Milo Yiannopoulos’s upcoming visit: it’s free speech

January 28, 2017 • 10:50 am

Next Wednesday, February 1, the ever-unruly Milo Yiannopoulos, Breitbart editor, provocateur, “alt-righter”, and reliable inciter of Regressive Left hatred, will be speaking at the University of California at Berkeley (UCB), invited by the Berkeley College Republicans (a student organization). Yiannopoulos’s talk is part of his continuing “Dangerous Faggot Tour.”

There will surely be trouble, for Milo + Berkeley = Attempted Censorship. (I’m becoming aware that, taking a playbook from some Muslims, campuses and students are starting to call Milo’s appearances “unsafe”—but precisely because students come out en masse to demonstrate in a violent way, and, once inside the auditoriums, to throw tantrums and try to shut the speaker down. If nobody showed up, or simply tried to demonstrate peacefully, the events would come off without a hitch. But that, of course, would take away one of the excuses for trying to ban Milo in the first place. In other words, the threat of violent retaliation for a perceived “hate speech” offense is a sufficient reason to disinvite the speaker.) In fact, twelve UCB professors originally signed a letter asking the Chancellor to cancel the event, and 90 others have added their names since. Here’s what one signatory said:

“We believe wholeheartedly in free speech and in the presentation of views that may be controversial or disturbing, politically or personally,” said David Landreth, one of the 12 professors who authored the letter, in an email. “However, Mr. Yiannopoulos’s public talks routinely veer into direct personal harassment of individuals; they often also call for such harassment and aim to incite it.”

Even if that were true (and I do deplore the singling out of one transgender student in a talk in Wisconsin), that’s not sufficient reason to cancel a talk. Note, too, the “we believe in free speech BUT” trope: the “but” is a sign you’re dealing with Regressive Leftists. And if they believe in free speech for views that may be “personally” disturbing, why do they decry “personal harassment”? If that harassment is defamatory or slanderous, it’s illegal, as it is if it calls for immediate violence. But if personally harassing individuals is a crime, then many comedians would be out of business now (Don Rickles comes to mind). In fact, Milo rarely calls out individual students, and when he does so they are usually “public figures,” as one could argue the Wisconsin student was. Beware, O beware the claim that speech should be band because it involves “personal harassment of individuals.”

As reported by the student newspaper The Daily Californian, Berkeley Chancellor Nicholas Dirks wrote a long letter to the campus community addressing Milo’s appearance. The letter is on the paper’s site, but you can access it more easily here. The good part is that Dirks defends Milo’s right to talk as free speech, e.g.:

Since the announcement of Mr. Yiannopoulos’s visit, we have received many requests that we ban him from campus and cancel the event. Although we have responded to these requests directly, we would like to explain to the entire campus community why the event will be held as planned. First, from a legal perspective, the U.S. Constitution prohibits UC Berkeley, as a public institution, from banning expression based on its content or viewpoints, even when those viewpoints are hateful or discriminatory. Longstanding campus policy permits registered student organizations to invite speakers to campus and to make free use of meeting space in the Student Union for that purpose. As mentioned, the BCR is the host of this event, and therefore it is only they who have the authority to disinvite Mr. Yiannopoulos. Consistent with the dictates of the First Amendment as uniformly and decisively interpreted by the courts, the university cannot censor or prohibit events, or charge differential fees. Some have asked us whether attacks on individuals are also protected. In fact, critical statements and even the demeaning ridicule of individuals are largely protected by the Constitution; in this case, Yiannopoulos’s past words and deeds do not justify prior restraint on his freedom of expression or the cancellation of the event.

Berkeley is the home of the Free Speech Movement, and the commitment to free expression is embedded in our Principles of Community as the commitment “to ensur(e) freedom of expression and dialogue that elicits the full spectrum of views held by our varied communities.” As a campus administration, we have honored this principle by defending the right of community members who abide by our campus rules to express a wide range of often-conflicting points of view. We have gone so far as to defend in court the constitutional rights of students of all political persuasions to engage in unpopular expression on campus. Moreover, we are defending the right to free expression at an historic moment for our nation, when this right is once again of paramount importance. In this context, we cannot afford to undermine those rights, and feel a need to make a spirited defense of the principle of tolerance, even when it means we tolerate that which may appear to us as intolerant.

But what I find problematic about Dirks’s letter is the bit where the University not only distances itself from Yiannopoulos’s views, which I guess is okay, but details some University actions that look for all the world like an attempt to “persuade” the College Republicans not to host Milo—or to disinvite him. To me, that smacks of attempted censorship.  Read the excerpt from Dirks’s letter below and tell me what you think; the material after the first paragraph almost sounds like attempted prior restraint:

Like all sponsors of similar events, BCR will be required to reimburse the university for the cost of basic event security. Law enforcement professionals in the UCPD have also explained to the BCR that, consistent with legal requirements, security charges were calculated based on neutral, objective criteria having nothing to do with the speaker’s perspectives, prior conduct on other campuses and/or expected protests by those who stand in opposition to his beliefs, rhetoric and behavior.

In addition, however, we have also clearly communicated to the BCR that we regard Yiannopoulos’s act as at odds with the values of this campus. We have emphasized to them that with their autonomy and independence comes a moral responsibility for the consequences of their words, actions, events and invitations – and those of their guest. We have made sure they are aware of how Yiannopoulos has conducted himself at prior events at other universities, and we have explained that his rhetoric is likely to be deeply upsetting and perceived as threatening by some of their fellow students and members of our campus community. Our student groups enjoy the right to invite whomever they wish to speak on campus, but we urge them to consider whether exercising that right in a manner that might unleash harmful attacks on fellow students and other members of the community is consistent with their own and with our community’s values.

Finally, we have also made the BCR aware that some of those who are opposed to Yiannopoulos’s perspectives and conduct have vowed to mount a substantial protest against his presence on our campus. UCPD has been directed to maintain public safety and to do what it can to prevent disruptions and preserve order. It should be noted that the anticipated cost of those additional preparations and measures will be borne entirely by the campus, and will far exceed the basic security costs that are the responsibility of the hosting organization. We will not stand idly by while laws or university policies are violated, no matter who the perpetrators are.

Nothing we have done to plan for this event should be mistaken as an endorsement of Yiannopoulos’s views or tactics. Indeed, we are saddened that anyone would use degrading stunts or verbal assaults on marginalized members of our society to promote a political platform.

That’s pretty damn paternalistic.

I wonder if the Administration does this when an anti-Israeli speaker comes to campus, or an anti-Palestinian speaker? How often does the administration have a sit-down with any student group and let them know with a nod and a wink that it might be better if they disinvited a speaker or hadn’t invited them in the first place?

Am I wrong, or do you think those words are out of place in Dirks’s letter? I can see why they were included: to show that the University is not on board with Milo’s message, thus trying to soothe the easily-offended students. But why should a University have to say any of this stuff in the first place? This wouldn’t have happened at the University of Chicago, where the administration would never try to position itself politically during a kerfuffle over a speaker.

Finally, below is a picture from a post on the San Francisco site Carpe Diem!calling for people to come out and drive Milo off campus. An excerpt:

Milo Yiannopoulos is a spokesperson for the newly activated far right, an Islamophobic writer for Breitbart, a leader of the Gamergate sexual harassment campaign, and a figurehead for some of the most hateful right-wing elements in Trump’s camp. We should allow no space for his message at UC Berkeley.

We also have to do more than stop one event to prevent these far right elements from recruiting and growing their forces. We have to shut them down and drown out their events in every community they pop up, and we have to undermine them politically as well.

Well, peaceful protest is one thing, but I don’t think this is what this group has in mind. . . .

Caturday felid trifecta: A lovely cat with vitiligo, Star Wars scene recreated with cats, Business Cat gets wormed

January 28, 2017 • 9:30 am

As usual, we have three cat-related items today. The first, from the reliable site LoveMeow, shows Scrappy, an 18-year-old cat who “suffers” from vitiligo, a condition in which patches of skin (and in this case, fur) lose their pigmentation. Scrappy was born black, and started getting patches of white in the last few years. He doesn’t seem to be suffering, but he’s certainly become a beautiful and unusual cat!

The amazing flies of the genus Richardia: sexual selection taken to extremes

January 28, 2017 • 7:30 am

I have a decent backlog of readers’ wildlife photos, but not enough to make me comfortable, so be sure to keep sending in your good pictures.

Today we’re taking a hiatus and featuring the amazing photographs of photographer and entomologist Gil Wizen, taken from his eponymous website (with permission; note that he also has a Twitter page and a Facebook page). I especially like these photos because they show the effect sexual selection can have on flies: in this case flies in the genus Richardia (the post from which I took these photos is “Photographing Richardia: a long way to victory“).

Gil’s photos were taken in Ecuador, and feature some really cool flies. (Note that these are copyrighted, and you must ask permission for both commerical or noncommerical reproduction.) Here, for instance, is an “antlered fly”, with Gil’s description (indented):

Males have antler-like projections from their eyes, which are used for pushing an opponent during a combat over territory or a mate. The female Richardia lacks those projections, but is characterized by a telescopic ovipositor at the tip of her abdomen, used for injecting eggs into fruits and other plant tissue.

The site also has an awesome close-up of the antlered head itself, so go over and see that. Here are the males: dorsal and frontal views. Note that the “antlers” are projections of the head itself, and are not antennae or aristae, which stick out straight in front in the first photo:

richardia-sp-mindo-768x512

richardia-sp-mindo-front-768x512

Richardia also includes ‘hammerheaded’ flies, in which the males (but not females) have their heads elongated laterally, resembling (but not related to) the “stalk-eyed flies” (diopsids).  The fact that only males have wide heads is a clue that sexual selection is going on, and indeed it is: in the form of male-male competition. As Gil notes:

The hammerhead Richardia can sometimes be seen on the underside of broad leaves such as those of banana and heliconia plants. Males engage in head-pushing tournaments while a single female usually stands by watching and waiting for the winner to approach. He will then display a short dance, running in circles and waving his decorated wings, before mating with her.

Clearly males with bigger heads have an advantage here; that’s what’s driven both the elongated heads and the sexual dimorphism. Here’s a male:

richardia-sp-hammerhead-1-768x512

And a female of the same species, having a “normal” head:

richardia-sp-hammerhead-female-768x512

Just to show the lengths to which sexual selection can go, below is a male from a different fly genus. Yes, those are the eyes on the tip of its head, and surely this design is not only maladaptive for fly vision, but also for flight. (If it were visually and aerodynamically good, the females would have it too.) Gil’s caption:

Male hammerhead fly (Plagiocephalus latifrons), dorsal view. One of the most amazing fly species out there in my opinion!

The behavior of this fly isn’t described, but I would bet $100 that the males engage in head-butting contests or “my head is bigger than yours” comparisons, with bigger-headed males generally winning. Of course, selection will only proceed to the point where the sexual advantage of having an even longer head is counterbalanced by natural selection against that lengthening, probably based on metabolic, visual, or aerodynamic constraints.

Look at that head!!:

plagiocephalus-latifrons-2-768x516

Gil wondered, as did I, how these huge heads could possibly fit into a pupal case. I guessed, based on the fact that flies also expand their wings after they hatch, that these males can also expand their heads after “eclosion” (hatching from the pupal case). That in fact is what happens. In the amazing BBC video below, also posted by Gil (narrator sounds like David Attenborough), you see a stalk-eyed fly right after hatching. It gulps air bubbles and forces them into its head to expand the eyestalks!

Thanks to Gil for permission to use the photos and Matthew Cobb for calling my attention to Gil’s post.

Snarky aside: as one reader below noted, some misguided souls might suggest that this sexual dimorphism isn’t the result of evolution, but is simply a social construct: males are raised to have long eyes! Well, we know that can’t be true (how do we know that?). At any rate, male-male competition is also a likely a behavior that, imposing sexual selection, led to sexual dimorphism in body size in our own species, with males being larger and having more muscle mass than females.  Imagine what human males would look like if they had to head-butt to win a mate!

Saturday: Hili dialogue

January 28, 2017 • 6:30 am

Good morning on a chilly Saturday (in Chicago): greet January 28, 2017. It’s National Blueberry Pancake Day, and I’ll add that to this wonderful breakfast treat you must add real butter and a drizzle of good maple syrup (preferably the darkest grade). It’s also Data Privacy Day (known as “Data Protection Day” in Europe), so remember not to give out compromising or secure things (if you’re in the U.S., NEVER give out your Social Security number on the phone, particularly during tax season). Beware of robot calls purporting to be from the Internal Revenue Service: I got four of those last year but knew they were a scam. Note that the IRS will never call you, so these calls are always attempts to steal your money.

Today is also the beginning of Chinese (Lunar)New Year; and there’s a Google Doodle; or should I say a Google Cock-a-Doodle? For it’s the Year of the Rooster, and if you don’t know your year, look it up (I’m a stalwart Ox).

On this day in 1547, Henry VIII of England died at the age of 55, a death probably hastened by obesity. His 9-year-old son became King Edward VI. In 1813, Jane Austen’s Pride and Prejudice was first published, and 7 years later a Russian expedition discovered Antarctica. On January 28, 1935, Iceland became the first Western nation to legalize therapeutic abortion. 1935! It’s also one of the world’s six most atheistic nations. On this day in 1956, Elvis Presley first appeared on US television. No, it wasn’t his famed (and censored) appearance on The Ed Sullivan Show, but a stint on CBS’s “Stage Show.” In 1965, the Canadian Parliament approved the current design for the Canadian flag (I think it should have a beaver rather than a maple leaf).

And, a sad day in 1986: the space shuttle Challenger blew up, killing Gregory Jarvis, Christa McAuliffe, Ronald McNair, Ellison Onizuka, Judith Resnik, Dick Scobee, and Michael J. Smith. I remember watching it live, with everyone uncomprehending and hoping beyond hope that nobody was hurt, even after the outcome was clear.

Notables born on this day include Henry Morton Stanley (1841), Colette (1873), Claes Oldenburg (1929), Alan Alda (1936), and Rick “Purpose Driven” Warren (1954). Those who died on this day, include beside Henry VIII and the seven Challenger astronauts, Charlemagne (814, probably wrong calendar) and W. B Yeats (1939), one of my favorite poets. Here’s Yeats’s grave in Drumcliff, Ireland; the inscription, penned by Yeats himself, comes from the final stanza of his great poem “Under Ben Bulben“:

Under bare Ben Bulben’s head
In Drumcliff churchyard Yeats is laid,
An ancestor was rector there
Long years ago; a church stands near,
By the road an ancient Cross.
No marble, no conventional phrase,
On limestone quarried near the spot
By his command these words are cut:
               Cast a cold eye
               On life, on death.
               Horseman, pass by!

Friday genitalia FTW

January 27, 2017 • 2:45 pm

Patricia Brennan is an evolutionary morphologist who teaches at Mt. Holyoke College (her website is here), and her speciality is animal genitalia. As the locus of morphological contact during reproduction, one would expect both natural and sexual selection to act very strongly on genitalia, and indeed they have (see William Eberhard’s underappreciated book Sexual Selection and Animal Genitalia). I suppose that because of a stigma attached to genitals, they aren’t studied nearly as much as they should be by evolutionary biologists. Here’s a video of Brennan and some of her work, first published at the xxfiles in Science.

Although biologists have concentrated on male genitalia, as those are often the most easily seen diagnostic features of related insects (that itself speaks to the importance of sexual selection, for why should genitals change so quickly compared to other traits?), Brennan also looks at the vaginas, which, being internal, are harder to see. She uses silicon molds to define their shape.

The male mako shark genitals described at 1:40 are way cool, and the spines on them probably show some kind of antagonism between male and female during copulation: the male wants to hold on to inject his sperm, but the spines don’t allow a female to reject such a male, and may damage her as well. You want more? Read about “traumatic insemination,” evolution’s version of Fifty Shades of Grey.

Brennan specializes in duck genitals, which can often be amazingly long and contorted (see one of her short videos at the Science page).

Pence: evolution denialist

January 27, 2017 • 1:15 pm

Ladies and gentlemen, if you’re an American, hear the words of your new Vice President as he disses evolution. The first one is from 2002, with Pence emoting on the floor of the House of Representatives. Pence is making that old argument that evolution is “only a theory,” which is clear when he argues that evolution is not a FACT. By now we should all know what a genuine scientific theory is—and it’s not just a guess or an idle speculation.  He then asks that “other theories of the origin of species” be taught, like the creationism adhered to by this nation’s founders—a creationism described in the book of Genesis—or the “theory of intelligent design.” He then says that the “truth of faith” will become apparent, whatever that means.

Yes, ladies and gentlemen, brothers and sisters, comrades: here is your Vice President:

(See some quotes at alternative media syndicate).

And here’s Chris Matthews boring into Pence as he waffles about evolution and global warming on the “Hardball” show. (The evolution bit starts at 1:37 and continues sporadically to the end.) This took place in 2009. Pence is waffling a bit more and giving evolution a bit less of the stink-eye, but he simply refuses to sign on to the scientific facts. Sadly, Matthews keeps asking Pence if he “believes in evolution,” which puts evolution into the status of a belief system, like religion. Far better to ask if he “accepts the scientific fact of evolution.”

Pence finally says that we need to teach all the “facts” to the kids and let the kids themselves sort it out. Of course, some of the “facts” he’s referring to are misguided attacks on evolution.

Rarely does one see a reporter give a politician this hard a time on evolution and science in general. I don’t remember any reporter even asking Trump what he thought about evolution.
