Readers’ wildlife photographs

August 4, 2014 • 1:46 am

Today’s post I’ll call “Pinker’s Birds.” Steve sent us a bunch of photos from his recent trip to Uganda, but the bulk of them were animals with feathers. To reduce the disparity among taxa (there were also herps, grazing mammals, and primates), I’m posting a few of his bird photos today.

Alcedo cristata (malachite kingfisher):

Monday: Hili dialogue

August 3, 2014 • 10:48 pm

Today I leave Dobrzyn, but of course the Hili dialogues will continue. I just won’t be in them. 🙁
Here the Princess tries to impress me with her knowledge of biology. The night before last, as well as last night, she stayed outside until morning, as she’s loath to roam when it’s hot outside.

Jerry: What did you do the whole night by the river?
Hili: I was studying the wild nature.

In Polish:

Jerry: Coś ty robiła przez całą noc nad rzeką?
Hili: Studiowałam dziką naturę.

 

Dobrzyn: Sunday

August 3, 2014 • 12:37 pm

Tomorrow afternoon it’s a sad farewell to the quiet village of Dobrzyn and my human and other mammalian friends. The post-Albatross vacation is nearly at an end, and who knows what criticism awaits me on my return?

But, for the nonce, I’m enjoying my final days. Here are some photos from yesterday, and I’ll tender my final report tomorrow before I leave. Tonight we had a nice bonfire (it’s cool in the evening) and communed with the stars, d*g, and cat with a few Zubrs.

Here’s the main square of the town. Our crib is about 2 km away (the town has 3,000 inhabitants).

Dobrzyn main sq

First some snaps of the Princess. Have you ever really looked at a tabby? They’re so common that we often ignore their beauty, like that of pigeons.  Look at this beautiful striped pattern on the forehead, with the upside down “M”:

I always wonder about the stripes that extend backward from the edges of the eyes. Cheetahs have them too; do they have an adaptive significance? If so, what is it?

Eye stripes

I bought Hili special Whiskas chicken in a sachet (Cyrus got treats, too: a chicken wing, as Ben Goren recommended, and other treats for his inflamed gums). Here Hili wolfs down the chicken (you can see her tongue):

Hili was proud to show me that since she’s lost weight, she can now fit on two jars instead of three:

What greater pleasure than a comfortable sofa, a book, and a purring cat? Here’s a selfie. Sadly, the book was The Bonobo and the Atheist:

In the afternoon, I helped Malgorzata make a plum tart (of course, she did most of the work, first rolling out the dough:

I pitted the plums:

And in a display of primate cooperativeness, we placed the plums on the dough:

Ready to bake:

Baked! (Not I but the tart.) Andrzej got to it before I could photograph it. It was good.

And dinner: chicken wings cooked with soy sauce, hoisin sauce, honey, oil and sesame seeds, served with delicious rice boiled in chicken broth and Polish cole slaw. It was all washed down with a new kind of beer, since one commenter dissed my beloved Zubr.  Dessert was, of course, plum tart.

Dinner

Here’s the beer I bought, which I know nothing about but bought because it cost more than the others. It was good: marginally better than Zubr. Perhaps a Polish reader can supply more details.

Tomorrow at 4 pm I’m off to Warsaw, and will fly home at noon on Tuesday. Thanks for joining me on my quiet interlude in Dobrzyn!

The real heroes

August 3, 2014 • 9:39 am

The word “hero” has been tossed around so readily that it’s almost lost its meaning, but there are real heroes, working today. A real hero is someone who risks his or her life to help others whom they don’t even know.

Here are a couple.

The first is Sheikh Umar Khan, the chief doctor in charge of haemorrhagic fever (Lassa fever and Ebola) in Sierra Leone. After treating more than 100 Ebola patients in the current outbreak, he contracted the virus and died on July 29, less than a week after he was diagnosed.

_76625302_dr_khan

As the BBC reports:

Shortly before he died, Dr Khan spoke to the BBC’s Umaru Fofana in Sierra Leone about the risks he and his colleagues face when treating infectious patients.

“Health workers are prone to the disease because we are the first port of call for those with the disease. Even with the full kit we put on we’re at risk.

“I’m afraid for my life, because I cherish my life. And if you are afraid then you must take the maximum precautions, stay vigilant and stay on your guard,” he said.

Second, members of Doctors without Borders dealing with the Ebola virus outbreak in West Africa, which has killed over 600 people this year.  Knowing that even their protective garb won’t fully protect them from this horrible disease, they go in and battle it anyway. Click the picture to get to a link with several dozen others:

Bear saves crow. But why?

August 3, 2014 • 8:45 am

by Matthew Cobb (with assistance from Prof. Ceiling Cat)

Reader Crary called this recently posted video to our attention, with the YouTube notes below. It’s gone viral ( >4 million views) so you may well have seen it. Spoiler: a bear in a zoo saves a crow from the moat around its enclosure.

My initial assumption was that the bear was going to eat it, but that clearly is not the case, as the ursine simply turns away and gets on with its carrots. It sure looks as if the bear is saving the crow. If he’s sequestering it to nom later he’s done a pretty poor job.

This “altruism” between distantly-related species mystifies both me and Jerry. Perhaps you have other ideas what is happening. At any rate, the crow was saved (we  hope).

The bonobo and the atheist-basher, part 2

August 3, 2014 • 6:30 am

I’ve now finished Frans de Waal’s book, The Bonobo and the Atheist, and my final evalution is what I said yesterday: it’s a decent disquisition on the evolutionary “roots” of human morality–roots discerned in behaviors like empathy, altruism, and concern for equity in our closest relatives, the chimpanzees. The book is useful reading for its eye-opening tales of ape “morality,” with the creatures evincing forms of compassion that we might not have expected.

Did I learn something from the book? Well, there are anecdotes about chimp compassion and altruism that are new to me, but I had already accepted the proposition that humans evolved an innate set of moral “rules” and emotions based on our millions of years of living in small groups of hunter-gatherers. It’s not at all hard to believe that natural selection would mold not just behaviors, but emotions (which of course underlie many such behaviors) that would impel us to take care of others, and to be better to those who behave better, while punishing “free-riders” and miscreants. And it’s not news to me that other primate groups have “proto-morality,” though it might be to others who haven’t read de Waal’s other books.

I disagree, though, that the behaviors and genes that make chimps and humans compassionate to “in-group” members are homologous–that they are genes inherited from our common ancestors. As I learned at a recent meeting in Oakland University, primate “morality” does not map neatly onto primate phylogeny. Orangutans, for instance, don’t show the sense of equity demonstrated by capuchin monkeys, even though orangs are more closely related to us than are capuchins.

It seems likely, at least to me, that natural selection independently molds behaviors based on how a species lives: orangs are solitary, capuchins gregarious. And other species, distant from us, show behaviors that look altruistic (whales, dolphins, dogs, and so on). So if we’re innately solicitous to members of our in-group, as I think we are, this may have evolved in our own lineage after we separated from the chimp lineage, and chimp and human behaviors are convergent, not homologous. This is supported by the very different forms of altruism and caring shown by bonobos vs. chimps, who diverged only about 1-2 million years ago, versus the 5-6 million years ago that our lineage diverged from that of both species of chimps. Social behavior is evolutionarily malleable. We may be able to learn about the evolution of altruism and cooperation in chimps by studying them, but not necessarily learn much about the evolutionary basis of morality in our own species. Remember that we did not descend from modern chimps or bonobos, but from common ancestors whose social system may have differed from all of ours.

What I learned most forcefully, though, was de Waal’s strong animus against “neo-atheists,” which he appears to define as atheists who actually criticize religion in a public or passionate manner. He sees that as an unseemly disturbance of people’s private behaviors, as an exercise in futility (“religion will always be with us”), and an unnecessary diversion from humanism, which he sees as the “right” way to effect change.  de Waal, apparently, can decry the foolish beliefs of religion but almost never mentions the harm it continues to do to the world. Indeed, he sees even the morality of nonbelievers as being based on that of their religious forbears. I deny that. I come from a long line of people who barely believed in God, and most of my moral education has been secular. That’s just an anecdote, of course, but time will eventually tell. Whatever “moral” influence religion exerts on nonbelievers (and de Waal claims, rightly, that religion is not a source of morality but can help perpetuate it), will wane as society becomes more secular. If you want to say that Danes and Swedes, though largely nonbelievers, are still moral because of their Christian ancestors whose ethos remains in their society, all your work is before you. For humans were, I think, moral long before they were religious.

At any rate, de Waal’s continual dissing of atheists may sit well with the public, but it detracts from the message of his book. After all, atheists largely stand with him on the source of morality. It is the religious people who make the claim that morality comes from God, and that religion is largely a moral enterprise. Why, then, de Waal’s obsession with running down people like Hitchens, Dawkins, and Sam Harris (I also get a swipe)? Who knows?

Things get pretty bad in the book’s last section, itself called “the bonobo and the atheist”. In the last few pages, de Waal imagines what a smart and loquacious bonobo would tell an atheist. It’s the usual blather: religion is with us, tread gently, be an “advocate” rather than a “protester,” and so on. It’s condescending, especially putting de Waal’s own sentiments in the mouths of a bonobo. If a smart bonobo really could talk to an atheist, it would probably say, “Give me some bananas, you heathen!”

Is the book worth buying and reading if you’ve read de Waal’s other works? My final judgement is “no.” de Waal’s earlier books have the same message without the annoying and superfluous atheist-bashing. The book is curiously disconnected and could have used considerable tightening. It is also infused with a kind of hubris that may be more detectable if you’re a scientist, for it’s clear to one in the field  how de Waal holds himself up as the paragon of the insightful and middle-of-the-road scientist, unswayed by extremists about human nature, and a forger of the reigning “consensus” view about human nature. That, too, I found annoying, especially because he takes others to task so often. de Waal has a very high opinion of himself.

But if you want to read nice anecdotes about bonobos, be my guest.  And do remember that my reaction may be conditioned by de Waal’s continually use of what I see as misguided arguments to attack my own form of nonbelief. But, of course, he’s an unbeliever, too! There is fertile material here for a sociologist: why do some atheists love to attack other atheists more than the religious beliefs that all atheists reject?

I close with two quotes from the book that got my dander up. The first is de Waal’s reaction to the television exchange between conservative pundit Bill O’Reilly and David Silverman (president of  the American Atheists); it’s the exchange in which O’Reilly infamously said that the tides could be explained only by God.  But de Waal also sees problems on the atheist side.

(pp. 88-89) All I get out of such exchanges is the confirmation that believers will say anything to defend their faith and that some atheists have turned evangelical. Nothing new about the first, but atheists’ zeal keeps surprising me. Why “sleep furiously” unless there are inner demons to be kept at bay. [JAC: in another place, de Waal imputes the zeal of “neo-atheists” to earlier trauma!] In the same way that firefighters are sometimes stealth arsonists  and homophobes closet homosexuals, do some atheists secretly long for the certitude of religion? Take Christopher Hitchens, the late British author of God is not Great. Hitchens was outraged by the dogmatism of religion, yet he himself had moved from Marxism (he was a Trotskyist) to Greek Orthodox Christianity, then to American Neo-Conservatism, followed by an “antitheist” stance that blamed all the worlds troubles on religion. Hitchens thus swung from the left to the right, from anti-Vietnam War to chneerleader of the Iraq War, and for pro to contra God. He ended up favoring Dick Cheney over Mother Teresa.

Some people crave dogma, yet have trouble deciding on its contents. They become serial dogmatists. Hitchens admitted, “There are days when I mis my old convictions as if they were an amputated limb,” thus implying that he had entered a new stage of life marked by doubt and reflection. Yet, all he seemed to have done was sprout a fresh dogmatic limb.”

It is this brand of grandfatherly tut-tutting, equating new causes and changes of mind as “serial dogmatism,” that infuriates me about this book. de Waal, of course, is above it all: never wavering, never wedded to a “dogma” (what we would call a “conviction”)—because, of course, that would make him as bad as both the religionists and atheists he decries.

On the next page he talks about a debate at the Ciudad de los Ideas conference I went to in Puebla, Mexico: Hitchens and Sam Harris debated religion against Dinesh d’Souza and Rabbi Shmuley Boteach:

(p. 90.) The circus-like atmosphere left me with my original question about evangelical atheists. It’s easy to see why religions try to recruit believers. . . But why would atheists turn messianic? And why would they play off one religion against another? Harris, for example, biliously goes after the “low hanging fruit” of Islam, singling it out as the great enemy of the West. Throw in a few pictures of burqas, mention infibulation, and who will argue with your revulsion of religion? I am as sickened as the next person, but if Harris’s quest is to show that religion fails to promote morality, why pick on Islam? [JAC: Maybe because some religions are more harmful than others? And Harris hardly leaves other religions alone! Remember the title of his second book: Letter to a Christian Nation?] Isn’t genital mutilation common in the United States, too, where newborn males are routinely circumcised without their consent? We surely don’t need to go all the way to Afghanistan to findf valleys in the moral landscape.”

Note the inflammatory language (“biliously,” “low hanging fruit”) as well as the willfully ignorant claim that all religious harms are equal. If you had the choice to be a Muslim male circumcised at birth or a Muslim female subject to genital mutilation, is it six of one, half-dozen of the other? If you think so, read Ayaan Hirsi Ali’s Infidel. Is Islam no worse than Quakerism? Give me a break. Perhaps the lowest-hanging fruit is the most poisonous fruit, as it was in the Garden of Eden. It is this painting (or rather tarring) atheism with a broad brush, this deliberate mischaracterization of its “militant” opponents, and the deliberate avoidance of New Atheist arguments, that makes de Waal seem less of a scientist and more of a sophist.

But the chimp stories are good, and de Waal’s speculations about the source of morality are worth pondering.

 

 

A new “geep,” a sheep/goat hybrid

August 3, 2014 • 5:11 am

I had long thought, and even taught, that sheep and goats couldn’t form viable hybrids, as they are very distantly related. Timetree puts them at a divergence of about 7 million years, which is the equivalent of a human and a chimp producing a viable offspring. (It’s been tried, believe me, and it doesn’t work. See WEIT for details.) I would sometimes tell students that cross-fertilization between the species produced hybrid embryos that would die early in development, an example of species distinctness enforced by “hybrid inviability.”

It turns out that’s largely true, but not entirely. Reader Merilee sent me a picture of a newborn  geep, an apparently healthy hybrid between the two species. That led me to a news website in Arizona that published a piece on a newborn geep on August 1 and showed and a video of the cute little thing. Here are the facts:

Butterfly may be Arizona’s only geep, a tiny tot with goat hooves and a goat head, but covered in wool. Her mom, Momma, is a sheep. Her dad, Michael, is a pygmy goat. Hence, geep. She was named Butterfly for her spots.

Baby+geep

As expected, Wikipedia has a good piece on the hybrids. It says, among other things, this:

A sheep–goat hybrid (sometimes called a geep or toast in popular media) is the hybrid offspring of a sheep and a goat. Although sheep and goats seem similar and can be mated, they belong to different genera in the subfamily Caprinae of the family Bovidae. Sheep belong to the genus Ovis and have 54 chromosomes, while goats belong to the genus Capra and have 60 chromosomes. The offspring of a sheep-goat pairing is generally stillborn. Despite widespread shared pasturing of goats and sheep, hybrids are very rare, indicating the genetic distance between the two species. Though sometimes called “geep”, they are not to be confused with goat-sheep chimerae, which are artificially created.

Knowing nothing about geeps, I would have guessed that any viable ones would be female (and probably sterile), in accordance with Haldane’s rule: the generalization that if only one sex of hybrids between species is either viable or fertile, that sex is almost invariably the “homogametic” one: the one with similar sex chromosomes. Since male mammals are the “heterogametic sex” (XY) and females are the homogametic (XX) sex, I’d expect geeps, if viable, to be female, and to be sterile because of the evolutionary distance between the parental species.

An aside: I worked on Haldane’s rule for much of my career, as it’s one of the few “laws” of biology–i.e., generalizations that are rarely violated–and for many years my students and I sought a general explanation for a phenomenon seen not only in mammals and insects–males heterogametic– but also in  birds and butterflies, groups which females are heterogametic and in which, in accordance with the rule, females are the sterile or missing hybrids. We think we have a good explanation for Haldane’s rule now, but if you want to read about it, see chapter 7 of Speciation by Coyne and Orr. It’s technical and a bit complicated.

Well, Butterfly is female, but we don’t yet know about her fertility. But Wikipedia suggests that Haldane’s rule has been violated in these species–the geep was both female and fertile.

On May 12, 2011, a healthy and fertile geep was born in Bant, Flevoland, the Netherlands. The geep mated with a ewe and on December 25, 2012 two healthy lambs were born.

Below is a video of a geep born on a farm in Ireland, and you can find pictures of other hybrids here. I expect reader Linda Grilli to weigh in soon, as she keeps goats and also rises very early. She will, I hope, tell us more about geeps, or about this hybrid.

Readers’ wildlife photos

August 2, 2014 • 11:52 pm

Reader Stephen Barnard sends a Northern Harrier and another photo of the rufous hummingbird (Selasphorus rufus) I posted yesterday. His notes:

The Northern Harrier (aka Marsh Hawk; Circus cyaneus):

1. Hears or sees the prey, probably a vole. (They hunt by ear a lot
which accounts for their owl-like heads.)
2. Makes a sharp turn with talons out.
3. Makes a mid-course correction.
4. Goes for the kill.

The hummingbird shot is especially fine, I’ll immodestly claim.

Here they are, in order:
