Rotorua and environs

April 5, 2017 • 10:30 am

Here’s a dollop of photos taken around and in Rotorua, where I was magnificently hosted by artist Geoffrey Cox and his wife, radiologist Barbara Hochstein.

On the long intercity bus ride from Wellington (7.5 hr), we stopped for lunch at a cafe where, the bus driver said, they had famous “lamburgers”, made from ground lamb. Of course I had to have one, and it was great, served with grilled onions, tomatoes, a special dressing, and salad.It was a juicy burger, and more people should serve these in New Zealand. I washed it down with a banana smoothie.

Waiting for the bus to leave, I found a ram to pet in a field next to the cafe. When I put my knee through the fence, he butted me!

Late afternoon sun on Lake Taupo, a large caldera lake that is the largest lake in New Zealand.

Sunrise from Geoffrey and Barbara’s house on Lake Rotorua. It was a gorgeous home, with a fantastic garden filled with native plants and a lovely interior filled with art.

The birds are New Zealand scaup, also called black teal (Aythya novaeseelandiae). It’s an endemic species.

Among Geoffrey’s interests are moas, and he’s illustrated books on them. He makes models of their skeletons, which takes weeks of work, since every detail is accurate and worked out in advance. First, a bit on moas from Wikipedia:

The moa were nine species (in six genera) of flightless birds endemic to New Zealand. The two largest species, Dinornis robustus and Dinornis novaezelandiae, reached about 3.6 m (12 ft) in height with neck outstretched, and weighed about 230 kg (510 lb).When Polynesians settled New Zealand around 1280 CE, the moa population was about 58,000.

Moa belong to the order Dinornithiformes, traditionally placed in the ratite group. However, their closest relatives have been found by genetic studies to be the flighted South American tinamous, once considered to be a sister group to ratites. The nine species of moa were the only wingless birds lacking even the vestigial wings which all other ratites have. They were the dominant herbivores in New Zealand’s forest, shrubland and subalpine ecosystems for thousands of years, and until the arrival of the Māori were hunted only by the Haast’s eagle. Moa extinction occurred around 1300 CE – 1440 CE ± 20 years, primarily due to overhunting by Māori.

Moa species names and numbers are in flux, as several species, once thought distinct, were found to be highly sexually dimorphic, with females 1.5 times as large as males and weighing up to three times more. Copulation must have been difficult!

Here’s Geoffrey with his handmade clay model of the giant moa DinornisYou can have Geoffrey make one of these for you—or nearly anything else—by going to his webpage:

A smaller moa; sadly, I’ve forgotten the species but I’ll ask Geoffrey:

H0w big were they? Below is a figure from Wikipedia. Given the lack of land mammals in New Zealand when the Maori arrived about 1280 AD, these birds would have been tempting targets, and easy to hunt. With drumsticks like these (the Maori didn’t eat much of the other parts), it’s no wonder all species were driven extinct in about 100 years of hunting.

A size comparison between 4 moa species and a human. 1. Dinornis novaezealandiae 2. Emeus crassus 3. Anomalopteryx didiformis 4. Dinornis robustus

Here’s Geoffrey’s preliminary sketch for the big moa model shown above. Tons of preliminary work go into the planning:

Moas lacked even external vestiges of wings, which even kiwis have. They were, in effect, the world’s only two-limbed vertebrates. The wing bones would have been attached to these bones underneath the ribs:


The moa’s tiny tail:

Geoffrey has done the artwork for three entire series of New Zealand postage stamps. One was of the extinct birds of New Zealand, and here’s a first day cover of the giant moa. The stamp itself is embedded in the portrait, center to the right:

A cast of the skull of a giant moa, with a $2 New Zealand coin for scale (about the size of an American quarter). This was made from a rubber mold used on a real moa skull in an Auckland museum.  Surprisingly, many moa bones survive, though not many entire skeletons or the fragile skulls.  Geoffrey even told me that two entire moa eggs, shells intact (but empty) were found by Europeans floating in a river in New Zealand.

Geoffrey also has a moa foot, with three big toes in front and a much smaller one in the rear.  The bones are genuine except for one replica bone and all the claws:

Geoffrey’s model (see coin for scale) of the fearsome talon of a Haast’s Eagle (Harpagornis moorei), a giant raptor that made its living by preying on hapless moa. When the moa went extinct,the eagle did, too. After having killed a moa, the eagle could consume it at leisure since there were n0 other carnivores to steal its prey.

Geoffrey will make you a replica of almost any creature by special order. Here’s his lovely model of the skeleton of a Woolly Mammoth (Mammuthus primigenius).

Only in New Zealand

Seen at the local pharmacy Taumarunui, where I’m visiting Heather Hastie—a beauty mask made of sheep placenta:

It seems to me that they should be marketing rat placenta beauty mask, killing two birds with one stone!

p.s. Heather says that the town is pronounced Toe-maa-roo-nu-ee, and that no European and very few New Zealanders can say it correctly.

Wednesday: Hili dialogue

April 5, 2017 • 6:30 am

by Grania

Morning all!

Anyone remember this couple?

They’re the Atom Spy Couple, Julius and Ethel Rosenberg. Both were executed in 1953 for  conspiracy to commit espionage. Today is the day they were convicted. Their children were 10 and 13 when their parents were executed.

In 1976 Howard Hughes died. The larger than life businessman, aviator and movie director’s life became the subject of the movie Martin Scorsese’s The Aviator in 2004.

Onto happier things (ha!); today is Pharrell Williams’ birthday (1973), he of Happy fame. He’s also the man responsible for the now slightly infamous song “Blurred Lines” performed by Robin Thicke, a song that managed to go to No 1 in the charts and be in the lead for worst songs ever recorded which is kind of a feat all by itself.

Spanish composer Alonso Lobo (1555-1617) died on this day. As is typical of people of this period, not much detail is known of his life. Most of it seems to have been spent in cathedrals, from choirboy to canon to maestro de capilla. 

In Dobrzyń Hili is staging a sit-in to protest her oppression by gravity.

A: Couldn’t you climb any higher?
Hili: Unfortunately, I’m blocked by a glass ceiling.

In Polish:

Ja: Wyżej już nie mogłaś wejść?
Hili: Niestety, ogranicza mnie szklany sufit

Finally, we get a video of Gus who is mercifully unoppressed and enjoying the Spring.

Insane political correctness: snowflakes urge destruction of Emmett Till painting

April 4, 2017 • 12:15 pm

If you know about the civil rights struggle in the U.S., you’ll know the story of Emmett Till. An African-American boy from near Chicago, Till, aged 14, went to visit relatives in Mississippi in 1955. There he was falsely accused of whistling at and flirting with a white woman. (It’s recently come to light that she completely fabricated that story.) Because of his supposed “crime”, Till was tortured and killed by the woman’s husband and his half brother.

The two men were arrested and tried for the kidnapping and murder of Till, but—as usual back then—were acquitted by an all-white jury, though the men later admitted they did the deed. (Laws against double jeopardy prevented another trial.)

Here’s Till a year before his murder:

When Till’s body was returned to Chicago, his face battered and mauled, his mother insisted on an open-casket funeral so people could see what had been done to her boy. I won’t show the picture, but you can see it here; it was published in the Chicago Defender, a black newspaper, and then republished widely, horrifying both black and white Americans. Till’s death and the open-coffin funeral did have a galvanizing effect on the civil rights movement, probably helping fuel the Montgomery (Alabama) bus boycott in late 1955.

Now, however, a painting based on the open-casket photo has stirred a big controversy in the art world—because it was painted by a white woman, artist Dana Schutz. The painting is below:

And the Guardian reports this:

At the centre of the battle over cultural appropriation is artist Dana Schutz’s expressionist painting Open Casket (2016), a gruesome depiction of Emmett Till, lynched in Mississippi in 1955.

The painting, on display at the Whitney Biennial exhibition, initially drew swift condemnation from critics who claimed Schutz, who is white, was taking advantage of a defining moment in African American history.

African American artist Parker Bright stood in front of the painting with Black Death Spectacle written on his T-shirt, and a young British artist, Hannah Black, accused Schutz of having “nothing to say to the black community about black trauma”, demanding that the work “be destroyed and not entered into any market or museum”.

Wikipedia‘s bio of Schutz gives more detail about the accusations of cultural appropriation:

Artist and Whitney ISP graduate Hannah Black started a petition for the painting to be removed, writing:

… it is not acceptable for a white person to transmute Black suffering into profit and fun, though the practice has been normalized for a long time. Although Schutz’s intention may be to present white shame, this shame is not correctly represented as a painting of a dead Black boy by a white artist — those non-Black artists who sincerely wish to highlight the shameful nature of white violence should first of all stop treating Black pain as raw material. The subject matter is not Schutz’s; white free speech and white creative freedom have been founded on the constraint of others, and are not natural rights. The painting must go.

Schutz responded, “I don’t know what it is like to be black in America, but I do know what it is like to be a mother. Emmett was Mamie Till’s only son. The thought of anything happening to your child is beyond comprehension. […] It is easy for artists to self-censor. To convince yourself to not make something before you even try. There were many reasons why I could not, should not, make this painting … (but) art can be a space for empathy, a vehicle for connection.”

Josephine Livingstone and Lovia Gyarkye of the New Republic argued Open Casket is a form of cultural appropriation disrespectful toward Mobley’s intention for the images of her son. [JAC: see that article here.] Describing how the painting undermines the photograph they wrote, “Mobley wanted those photographs to bear witness to the racist brutality inflicted on her son; instead Schutz has disrespected that act of dignity, by defacing them with her own creative way of seeing.” Scholar Christina Sharpe, one of 34 other signers of Black’s letter, argued for the destruction of the painting so that neither the artist nor future owners of the painting could profit off it.  Schutz’s work reportedly goes for up to $482,500 at auction.

Here’s Parker Bright protesting the painting:

Art News has published Hannah Black’s open letter to the Whitney asking that the painting be removed. Besides the bit above, Black wrote this:

As you know, this painting depicts the dead body of 14-year-old Emmett Till in the open casket that his mother chose, saying, “Let the people see what I’ve seen.” That even the disfigured corpse of a child was not sufficient to move the white gaze from its habitual cold calculation is evident daily and in a myriad of ways, not least the fact that this painting exists at all. In brief: the painting should not be acceptable to anyone who cares or pretends to care about Black people because it is not acceptable for a white person to transmute Black suffering into profit and fun, though the practice has been normalized for a long time.

. . .Through his mother’s courage, Till was made available to Black people as an inspiration and warning. Non-Black people must accept that they will never embody and cannot understand this gesture: the evidence of their collective lack of understanding is that Black people go on dying at the hands of white supremacists, that Black communities go on living in desperate poverty not far from the museum where this valuable painting hangs, that Black children are still denied childhood. Even if Schutz has not been gifted with any real sensitivity to history, if Black people are telling her that the painting has caused unnecessary hurt, she and you must accept the truth of this. The painting must go.

To Parker Bright, Hannah Black, and other critics of this painting, I say this:

I completely reject your criticism. If only artists of the proper ethnicity can depict violence inflicted on their group, then only writers of the proper ethnicity can write about the same issues, and so on with all the arts. And what goes for ethnicity or race goes for gender: men cannot write about suffering inflicted on women, nor women about suffering inflicted on men. Gays cannot write about straight people and vice versa.

The fact is that we are all human, and we are all capable of sharing, as well as depicting, the pain and suffering of others.  I will not allow you to fracture art and literature the way you have fractured politics. Yes, horrible injustices have been visited on minority groups, on women, on gays, and on other marginalized people, but to allow that injustice to be conveyed only by “properly ethnic or gendered artists” is to deny us our common humanity and deprive us of emotional solidarity. No group, whatever its pigmentation or chromosomal constitution, has the exclusive right to create art or literature about their own subgroup. To deny others that right is to censor them.

To those who say this painting has caused them “unnecessary hurt” because it is by a white artist about black pain, I say, “Your own pain about this artwork is gratuitous; I do not take it seriously. It’s the cry of a coddled child who simply wants attention.”

As for the accusation that this painting was done for “profit and fun,” that’s a disgusting and reprehensible thing to say. We cannot allow the Culture of Offense to rule the Culture of Art. If art is to flourish in a free society, it can be criticized, but it cannot be censored.

Emmett Till was black, but his story belongs to all of us.

My conversation with Richard Dawkins: Washington D.C. (and your chance to submit questions)

April 4, 2017 • 10:30 am

Richard Dawkins is doing a four-appearance visit to the US next month:


The four stops on the tour are Los Angeles, Boulder, Washington, and Miami (with Dave Barry doing the discussion there!), and they’re being held to benefit the Center for Inquiry.

On May 24, at the Lisner Auditorium in Washington, D.C., I’ll have an hour’s conversation with Richard onstage, and then both of us will answer questions for half an hour—though I think people should be querying Richard and not me (I’m fully aware of whom they’re coming to see!).

Tickets are only $29, or, if you’re flush, $250 for the special VIP package. Go to the link in the first paragraph, or click on the screenshot below, for information on the event.

To buy tickets, go here or click on the screenshot below. They’ll go fast—as usual when Richard talks.

Finally, I’ll crowdsource here some questions or topics you’d like to hear Richard discuss. What would you like him to talk about, or what questions would you put to him? I have some ideas, of course, a few based on his upcoming book of essays; but some input from readers would be useful.  Everybody suggest one question! (I’ve already asked him the “boxers or briefs” question when we last chatted at Northwestern University. I also said he didn’t have to answer that one.)

If you’re in Washington, I’ll see you there. They’ll be selling my books as well as Richard’s, so you can have one with a cat drawn in for this special occasion.

Wetas, cave wetas, and lagniappe (cat versus weta)

April 4, 2017 • 9:30 am

Some of the most unusual endemic insects in New Zealand are the wētā, orthopterans. They’re often referred to as “crickets,” but they’re in the families  Anostostomatidae and Rhaphidophoridae and not the cricket family (Gryllidae). Although Wikipedia says that there are 70 species of wētā (all endemic to this country), there are doubtlessly a lot more, as another guide I have lists several unnamed species.

Besides all New Zealand species of wētā being flightless, they are famed for their fierceness and size. The world’s heaviest insect is the Little Barrier Island Giant Weta (Deinacrida heteracantha), weighing in at a ponderous 9-35 grams (0.3-1.3 oz), but can weigh as much as 70 grams (2.5 ounces), which means that only about 6 of the biggies would weigh a pound. Here are two pictures of that species (not my photos):

These now live on the island as they were destroyed by introduced mammalian predators. The early Maori also liked to eat them. (See here for additional facts.)

Another strange species is the Mountain Stone Wētā (Hemideina maori). A denizen of high altitudes on the South Island, it can survive being frozen solid for months. Wikipedia says this (see also here and here):

Mountain stone weta can survive being frozen for months in a state of suspended animation down to temperatures of about -10 °C. At temperatures below -10 °C approximately 85% of their body water is crystallised, which is one of the highest ice contents known for any animal. During winter their haemolymph (the insect equivalent of blood) contains low molecular weight  cryoprotectants such as amino acids especially proline (up to about 100 mM) and the disaccharide trehalose. These substances are synthesized during autumn and their concentration decreases again during spring and summer (Proline concentration decreases to about 10 mM during summer). The amino acids and sugars presumably help to decrease the ice content colligatively. However, they probably also have a direct protective effect on membranes and proteins via direct interaction or by modifying the water layer with the closest proximity to the molecules. It also displays the defensive behaviour of “playing dead”, by lying still for a short time on its back with legs splayed and claws exposed and jaws wide open ready to scratch and bite, this behavior is often accompanied with regurgitation.

Here’s a Mountain Stone Wētā (not my photo):

Finally, Tree Wētā of several species (genus Hemideina) are common, and they’re fearsome, as males have huge heads and can inflict a nasty bite (they’re found in dead wood, and can live in firewood piles around houses). This video shows a cat encountering what I think is a tree wētā. Look at that head and those pincers! The sexual dimorphism probably indicates that the males fight each other for females.

Two days ago Geoffrey, my host, took me on a hike above Lake Okatina to look for cave wētā. There are several species, all of course living in caves, and all with huge antennae and long, spindly legs. The species we were looking for is almost certainly the Oparara Cave Wētā (Gymnoplecton spp.)  Geoffrey had spotted them before in these shallow caves that the Maori dug in hillsides that, when first used, were on nearly vertical slopes that have now eroded into hills.

It’s not clear why the Maori dug these caves: it could be to store the bones of their ancestors, their food, or even to hide out (they can hold one or two people). What is clear is that they’re inhabited by hordes of cave wētā, which can bite. When you crawl into one of these caves with a flashlight, you have to make sure you don’t brush the opening or the top, or you could get bitten. It’s a bit anxiety-inducing!

Once inside, when you shine the flashlight on the ceiling, you find it covered with cave wētā, which, with their long legs and longer antennae, look like spiders. I’m not generally a timid person, but I was fearful they’d all come raining down on me!

These photos were taken by using a flashlight to focus the camera, and then, turning off the flashlight, shooting blindly at the ceiling. I think they turned out well, all things considering:

I inverted this photo so you could see its features. They normally hang upside down on the ceiling. Note the reduced eyes, common in cave animals.

Because the Maori complained that Europeans raided caves to steal the treasures interred with their ancestors, the New Zealand government built this concrete bunker atop the hill to house the remains, complete with a lockable steel door. But of course that got broken into as well, and now Maori bury their dead in special cemeteries. Geoffrey said that there were rumors that this bunker, once emptied, was inhabited by a European hermit for two decades. It’s a horrible place to live as it’s cold, dank, and dark, and I’m not sure that story is true!

This brief animated video was made by my final year student, Izzy Taylor, as part of her Zoology degree. It’s all her own work. She needs comments from viewers, so I’d be very grateful if you could spend 7 minutes having a quick look, and then posting your views – suggestions, criticisms, plaudits – in the comments below. I promise you’ll learn something interesting!
