International cat day: Readers’ cats

September 25, 2013 • 1:07 pm

I continue the series of readers’ cats that began on International Cat Day in August.  If you have a photogenic felid and a good story behind it, send it along, though I can’t guarantee that I’ll use every cat.

Reader Robert presents us with his erudite moggie and a brief note:

Here is my contribution. This is Kira, and I swear by her and my soul this wasn’t staged.

The duck-faced lacewing, its baby and an ancient Egyptian inscription

September 25, 2013 • 10:13 am

by Matthew Cobb

Another set of fascinating insect tw**ts popped up while I slept. Morgan Jackson (@BioInFocus) tweeted a link to this fantastic insect, photographed by J. Gállego, a Spanish photographer who specialises in the fauna and flora of Spain and North Africa:

Here’s picture of the beast head on (keep away from those mouthparts!):

Some of you may have guessed, this is a larval form of a rather beautiful insect – a Neuropterid. This includes things lacewings, owlflies and antlions, and used to be in the same group as the Megaloptera (which includes the Dobson fly we discussed the other day). Antlion larvae live in pits, into which ants fall (hence their name), which was also the inspiration for that beast in one of the episodes of Star Wars. After Morgan had tweeted this bizarre larva – why on earth does it have such a long ‘neck’? – he then tweeted this:

neuorptera

Here’s the picture Morgan linked to – a stupendous image by the great Piotr Naskrecki from thesmallermajority.com. You can see what he means about ‘crazy hind-wings’:

Spoon-winged lacewings (?Nemia sp.) from Richtersveld National Park, South Africa [Canon 1Ds MkII, Canon 100mm macro, 2 x Canon 580EX]

Here’s a close-up of the beast, again by Piotr Naskrecki, in which you can really see that they are duck-faced…

The head and mouthparts of spoon-winged lacewings is elongated and well-adapted for fitting into long corollas of flowers [Canon 1Ds MkII, Canon 100mm macro, 2 x Canon 580EX]

These things look more like Mecoptera or scorpion flies (neither scorpions nor flies, obvs). Very odd.

J. Gállego has a photo of a different species, which might be the adult of the weird larva at the top – Nemoptera bipennis:

Here’s another beautiful Nemoptera bipennis from Toni Garcia de la Cruz.

You can find many other photos of the adults on the internet, including these and a great page of loads of Neuropterid images collated by Jonathan Wojcik. There’s even a nice Youtube video:

The function of those long hindwings is unclear (though they look remarkably like the streamers seen in some birds, for which sexual selectionis a probable explanation), but Naskrecki has a different take:

The function of this unusual morphology is still not entirely known. In species with particularly enlarged hind wings their function appears to be to deter some predators by giving a false impression of the insect as much larger—and thus potentially stronger—than it really is. In species with long, thread-like wings their function may be related to the aerodynamics of the flight, and in members of the subfamily Crocinae the hind wings play a sensory function in cavernicolous habitats that these insects occupy.

I was particularly struck by this comment from Piotr:

Interestingly, because of some species’ preference of sheltered, cave-like habitats, the larvae of these insects were first discovered in tombs of the pyramids of Giza in Egypt in the early 1800′s, giving rise to a nearly mythological status of these insects.

A couple of years back I was in the back rooms of the Manchester Museum (part of the University of Manchester), where some colleagues were preparing an ancient Egyptian tombstone (I think). I was struck by a hieroglyph of an insect of some kind, which I was told was a bee, so I took a photo of it that has been sitting on my phone ever since. I wasn’t happy with the identification of the thing as a bee (it doesn’t look anything like one – look at those antennae!), but that is apparently how it is interpreted, and other inscriptions relating to honey and everything all make sense.

But looking at it now, it looks much more like a duck-faced lacewing (dig those antennae!):

The shape underneath the abdomen is apparently one of the back pair of legs, and can be seen more clearly on this inscription from Luxor:

File:Luxor, hieroglyphs on an obelisk inside the Temple of Hatshepsut, Egypt, Oct 2004.jpg

So. Either the Ancient Egyptians didn’t know their bees from the duck-faced lacewings (it seems unlikely), or the bee symbol was adapted from an earlier symbol which was (for whatever reason) of a duck-faced lacewing. Any Egyptologists care to comment?

Richard Dawkins on The Daily Show

September 25, 2013 • 7:14 am

As you may know from Greg Mayer’s post five minutes before airtime, Richard Dawkins was on The Daily Show last night, being interviewed by Jon Stewart about Richard’s new autobiography, An Appetite for Wonder.  You can find the full episode here, with Dawkins appearing at 13:33 until the end of the show at 36:00 (just move the video cursor to the second black mark).

The discussion is worth watching, as Richard acquits himself well (see his concise explanation of the limits of “selfish genes” at 22:00), but Stewart hadn’t really done his homework, and missed some chances to delve more deeply into things he brought up, like the incompatibility of science and religion (Stewart mentions it twice). Instead, Jon is all over the map about topics as diverse as morality, the origin of life, and so on.  And, in trying to cover too many topics, Stewart doesn’t let Dawkins go into any detail about a single one, as in the discussion about whether religion really can provide net benefits to humanity. He permits Richard only to emit a series of sound bites. Nevertheless, a message got out, and that’s better than nothing.

Sadly, there’s no indication that Stewart even read Richard’s book!  Finally, the host talks too much. A rule of interviewing, to which I’ll scrupulously  adhere next Thursday, is to let the interviewee do at least 75% of the talking.

Finally, I don’t appreciate Stewart’s comment on cats at 34:15!

Gary Gutting goes after scientism in the NYT, calls Augustine an evolutionist

September 25, 2013 • 5:05 am

I’ve decided I don’t want to waste time extensively rebutting critiques of scientism: there are too many of them, and they all say the same thing. Instead, for those who maintain an interest in this topic, I’ll summarize them as briefly as I can.

In the September 18 “Opinionator” column of the New York Times, “Science’s humanities gap,” Gary Gutting (a philosophy professor at Notre Dame), wastes a lot of space complaining that people like Steve Pinker call for more sciences in the humanities, but never call for putting more humanities in the sciences. Scientists should, he says, learn more philosophy.

I take issue with that on two grounds: scientists are so pressed for time that we can barely get our own work done and, more important, the potential benefit of philosophy to the conduct of science seems less to me than the potential benefits of infusing humanities with science—benefits described out by Steve in his New Republic piece.

I am not saying that philosophy or the humanities are without value. Far from it. What I am saying is that the marginal benefit of adding more science to the humanities is greater than vice versa. I personally absorb tons of what could be considered “humanities,” including literature, nonfiction, art, and philosophy. They’ve enriched my life immensely—but I can’t say with confidence that they’ve made my science better, or different.  I’d still have published the same work on speciation if I’d never read philosophy, although I wouldn’t be writing this website.  My benefits are personal, not scientific.

But enough of that. What I want to say is that Gutting makes one statement that’s a blatant falsehood:

Pinker also claims that science has shown that all traditional religious accounts of “the origins of life, humans, and societies — are factually mistaken,” since “we know. . . that humans belong to a single species of African primate that developed agriculture, government, and writing late in its history.” Here Pinker ignores the numerous religious thinkers, from Augustine to John Paul II, who have accepted an evolutionary account of human origins, maintaining that the process itself is the work of a creative God.

That’s just bullpucky.  Really? Augustine, who believed in an instantaneous creation of all existing species, a global flood, and a literal Adam and Eve—an evolutionist? You can see him that way only if you’re blinded by the tendentious blinkers of accommodationism. Does Gutting really need an atheist biologist to correct him on matters of religious philosophy?

As for Pope Paul II, his famous 1996 message to the Pontifical Academy of Sciences does accept a form of evolution:

Today, more than a half-century after the appearance of that encyclical, some new findings lead us toward the recognition of evolution as more than an hypothesis.*  In fact it is remarkable that this theory has had progressively greater influence on the spirit of researchers, following a series of discoveries in different scholarly disciplines. The convergence in the results of these independent studies—which was neither planned nor sought—constitutes in itself a significant argument in favor of the theory.

Sounds good, eh? Until you read more:

And to tell the truth, rather than speaking about the theory of evolution, it is more accurate to speak of the theories of evolution. The use of the plural is required here—in part because of the diversity of explanations regarding the mechanism of evolution, and in part because of the diversity of philosophies involved. There are materialist and reductionist theories, as well as spiritualist theories. Here the final judgment is within the competence of philosophy and, beyond that, of theology. . .

What are those materialist and reductionist theories, much less the spiritual ones? I am aware of only one going theory of evolution, which, while it has its controversial parts, does not deal with “materialism vs. reductionism” much less “spiritualism.”

And this (my emphasis):

. . .the human person cannot be subordinated as a means to an end, or as an instrument of either the species or the society; he has a value of his own. He is a person. By this intelligence and his will, he is capable of entering into relationship, of communion, of solidarity, of the gift of himself to others like himself. St. Thomas observed that man’s resemblance to God resides especially in his speculative intellect, because his relationship with the object of his knowledge is like God’s relationship with his creation. (Summa Theologica I-II, q 3, a 5, ad 1) But even beyond that, man is called to enter into a loving relationship with God himself, a relationship which will find its full expression at the end of time, in eternity. Within the mystery of the risen Christ the full grandeur of this vocation is revealed to us. (Gaudium et Spes, 22) It is by virtue of his eternal soul that the whole person, including his body, possesses such great dignity. Pius XII underlined the essential point: if the origin of the human body comes through living matter which existed previously, the spiritual soul is created directly by God (“animas enim a Deo immediate creari catholica fides non retimere iubet”). (Humani Generis)

As a result, the theories of evolution which, because of the philosophies which inspire them, regard the spirit either as emerging from the forces of living matter, or as a simple epiphenomenon of that matter, are incompatible with the truth about man. They are therefore unable to serve as the basis for the dignity of the human person.

6. With man, we find ourselves facing a different ontological order—an ontological leap, we could say. But in posing such a great ontological discontinuity, are we not breaking up the physical continuity which seems to be the main line of research about evolution in the fields of physics and chemistry? An appreciation for the different methods used in different fields of scholarship allows us to bring together two points of view which at first might seem irreconcilable. The sciences of observation describe and measure, with ever greater precision, the many manifestations of life, and write them down along the time-line. The moment of passage into the spiritual realm is not something that can be observed in this way—although we can nevertheless discern, through experimental research, a series of very valuable signs of what is specifically human life. But the experience of metaphysical knowledge, of self-consciousness and self-awareness, of moral conscience, of liberty, or of aesthetic and religious experience—these must be analyzed through philosophical reflection, while theology seeks to clarify the ultimate meaning of the Creator’s designs.

Evolution and neuroscience haven’t yet found a soul, and all evolutionary progress has made without assuming there is some divine “ontological leap” between humans and other creatures.  Indeed, a genetic continuum is the assumption that’s produced our progress. But here John Paul is saying that consciousness and other features of human mentation are to be explained not by science, but by God.

Did I mention that the official position of the Roman Catholic Church is also that there was a historical First Couple—Adam and Eve—who were the genetic ancestors of us all?

The vaunted Pope was limning a watered-down theistic view of evolution, not the one held by scientists.  Even if your view of “theistic evolution” is one in which God simply created the conditions for evolution to occur, rather than steering it in certain directions (the Pope’s held the latter view), it’s still not a scientific view. It’s a metaphysical view laden with woo.

As for Augustine, Gutting should go back and read him again before putting him in the box with Darwin.

Dawkins tickets still available

September 24, 2013 • 3:14 pm

A week from Thursday I’ll be “interviewing” Richard onstage at Northwestern University as part of his U.S. tour. There will be questions about his book, An Appetite for Wonder, but I hope to engage in a more wide-ranging conversation (many of you suggested questions a while back).

At any rate, I’m told that tickets are still available ($10 general, $5 for students; credit cards only), but they’re going fast.  You can purchase them, and get information about the event and time, at this site.

After our conversation Richard will answer audience questions for a while, and then he’ll sign copies of his book (warning: he won’t sign copies of other books you bring see correction below by Richard in comment #12; he’ll sign his other books, but not dedicate them).

I’m also told that I’ll have some copies of WEIT to sign at the kiddies’ table.

I may have a few tickets to spare near game day, so stay tuned. I sense a contest in the making.

Golden eagle kills deer

September 24, 2013 • 12:35 pm

About half a dozen readers have sent me this series of photographs, showing an incident reported in several places, including Nature News and the Daily Mail  (quotes from the former, photos [credited to Linda Kersey of the Zoological Society of London] from the latter). It show what seems to be the first documented attack of a golden eagle on a deer.

In a series of three images over the course of just seconds, a camera trap in the Russian Far East photographed a golden eagle [Aquila chrysaetos] attacking a sika deer [Cervus nippon].

A camera trap in the forest of the Russian Far East captured rare and surprising images of a golden eagle attacking a young sika deer.

Golden eagles are not known to attack deer, but the image of the bird latched on to the deer’s back and bringing it down to the snowy ground is as clear as it is puzzling. The eagle’s attack was successful, researchers later found the deer’s carcass a few yards away from the camera trap.

“I’ve been assessing deer causes of death in Russia for 18 years — this is the first time I’ve seen anything like this,” said Linda Kerley of the Zoological Society of London (ZSL), who found the images so compelling that she co-authored a paper on the attack in the Journal of Raptor Research.

Kerley said she was preforming a routine check to switch out the camera trap’s batteries and memory cards when she noticed the deer carcass in the snow. But something in the scene was off, she said.

“There were no large carnivore tracks in the snow, and it looked like the deer had been running and then just stopped and died,” Kerley said. “It was only after we got back to camp that I checked the images from the camera and pieced everything together. I couldn’t believe what I was seeing.”

It looks as if the eagle is trying to fly away with the deer, though they’ve been known to attack prey clearly un-carryable.

Camera trap images are typically recordings of common prey species and occasionally a resident or transient tiger, so seeing an image of an eagle in the act of taking down a deer was unexpected. But Jonathan Slaght of the Wildlife Conservation Society and Kerely’s study co-author, said golden eagles have a well-documented history of eyebrow-raising predation attempts.

“The scientific literature is full of references to golden eagle attacks on different animals from around the world, from things as small as rabbits — their regular prey — to coyote and deer, and even one record in 2004 of an eagle taking a brown bear cub,” Slaght said.

Slaght added that Kerley was “really lucky” to have obtained images of such a rare and opportunistic predation event.

And the remains.  This is of course saddening, but it’s nature red in beak and claw.  I’m amazed the deer couldn’t get away.
