Caturday felid trifecta: Cat-food ad with complicated machine, parkouring cat, and the Friskies awards for best cat video

September 27, 2014 • 7:14 am
Reader Michael from the UK sent two videos of a cat-food commercial involving a very complicated machine that dispenses cat food. He noted that the machine is similar to those designed by the British illustrator Heath Robinson and his American counterpart Rube Goldberg.
The ad is for Felix brand “Crunchy Crumbles” (I haven’t seen this in the US), a felid meal that involves adding a packet of crunchy bits to an attached sachet of wet food.  The machine used in the first commercial is real; there is no human intervention once it’s started. It’s a really nice commercial, and stars a cute tuxedo cat also named Felix. The second video, a longer one, tells how the commercial was made, and how long it took (months!):
Michael’s notes:
The ad itself has more cat [than the “making of” video below]:
Felix enters halfway through this video on the making of the ad—has an enjoyably “luvvy” English director wearing a scarf indoors (not a spoof):

Readers’ wildlife photos

September 27, 2014 • 5:02 am

Let’s start off with a lovely Idaho landscape by reader Stephen Barnard, which he labeled, “My Maxfield Parrish impression.” And sure enough, it is (Parrish is one of my favorite popular illustrators.)

He labeled it an “HDR” landscape, and when I asked what that was, he replied, “It’s three shots on a tripod at +/- 1ev. I put them together with an  app. It’s easy. Your stormy Chicago skylines would be an excellent subject.”

If you’re unfamiliar with Parrish (1870-1966), here’s one of his illustrations (“Romance,” 1922). He was known for his pastel-ish hues and grandiose, romantic imagery:

Some nest parasitism by birds, photographed by reader Brian Peer, who explains:

I have some photos of my “real” area of research: avian brood parasitism. A couple weeks ago Bruce Lyon mentioned the parasitic cuckoos he photographed in China. Here in North America, we have only one widespread interspecific avian brood parasite, the Brown-headed Cowbird. [Molothrus ater]. Cowbirds, like many of the cuckoos, never build their own nests and lay their eggs in the nests of other birds. When these “hosts” are parasitized by a cowbird they typically raise fewer of their own young, and in some instances they raise only the cowbird and none of their own young. I’m particularly interested in why so few hosts (~10%) reject cowbird eggs in spite of the costs to their reproductive success.  [JAC: This goes to show you that some selective pressures don’t elicit a response: nature isn’t perfect.  Any case of parasitism, like this one, is a failure of natural selection (in this case on the part of the host bird.]

I’ve attached photos of parasitized host nests. The lack of egg rejection by some hosts is likely due to the similarity of cowbird and host eggs, including the Northern Cardinal. However, there are other hosts that have eggs clearly distinguishable from cowbird eggs (Wood Thrush and Red-winged Blackbirds) yet they accept parasitism.

The cowbird eggs are white with brown and gray spots. The catbird is a “rejecter” meaning that it removes cowbird eggs laid in its nest, whereas the blackbird and wood thrush are “accepters” which accept most parasitic eggs.

Northern cardinal nest with cowbird egg:

As you can see, cowbird eggs are very similar in appearance to cardinal eggs. Cardinals rarely reject cowbird eggs and occasionally reject their own eggs from parasitized nests by accident.

This photo is a Field Sparrow nest with two sparrow eggs (smaller) and two cowbird eggs. Again, other than the size difference, these eggs are similar in appearance:

OMG: Monster leech swallows giant worm

September 26, 2014 • 2:06 pm

Reader “pyers” called my attention to a Torygraph article about an upcoming BBC documentary, “Wonders of the monsoon,” that is a must-watch. But the Torygraph piece has a title more suited to the Daily Mirror, to wit (click on the headline to go to the article):

Screen Shot 2014-09-26 at 2.12.27 PM

Indeed, that’s just what happens, and for those of you who like nature red in tooth and claw, by all means read the piece and then watch the movie at the bottom of the article. You can also go directly to the BBC clip (which also plays in the US) by clicking the screenshot of the carnage just below:

Screen Shot 2014-09-26 at 2.11.37 PM

From the Torygraph:

It resembles a monster from a b-list horror film but deep in the forests of Borneo this giant leech really exists and is a deadly predator.

The creature is so new to science that it does not yet have a taxonomic name. It is known to the tribes of Mount Kinabalu as the ‘Giant Red Leech.’

It was filmed for the first time by BBC filmmakers for the new series ‘Wonders of the Monsoon.’

The Giant Red Leech is one of the biggest in the world. The specimen captured on camera was around 30cm long but experts believe they could grow larger.

They have grown so big that they no longer simply suck blood but now actively hunt giant blue worms and suck them down like spaghetti. The worm it is eating is a whopping 78cm.

That’s about 31 inches to you non-metrics—more than twice the length of the leech. How does the leech find room?

Finding the species on Mount Kinabalu, the biggest mountain in Borneo, was a huge challenge and the team worked with ecologist Alim Bium to locate the leech.

“If you want to film a predator the best thing to do is to find its prey” said Williams, but it took the team several weeks of searching before an extremely heavy rainstorm eventually brought worms out in huge numbers. The red leeches were not far behind.

“By working with Alim we were able to sufficiently light the area of forest to record the predation as it unfolded” said Paul.

“It was exciting and fascinating, as he was making his new scientific discovery, we were documenting the behaviour for the very first time”

That last quote is the kind of thing that gives biologists a bad reputation!

There’s a lot more in the article about the show, including filming a colony of 300,000 flying foxes.  Be sure to watch it if you’re in the UK! Info:

Fishes mimic leaves

September 26, 2014 • 12:52 pm
 

In about three weeks I’ll be giving a popular lecture on evolution in Bulgaria—that’s right, Bulgaria! I’m very excited, for who ever gets to go to that country? I will, and will spend a week travelling about, seeing the sights, consuming the local comestibles (including the famous yogurt), and, of course, meeting the local biologists.

They wanted a talk that would interest a general audience (it’s part of a public lecture series) but also teach them some evolution. Since I’m tired of the evidence-for-evolution talk, I decided to talk about mimicry. You know from my (and Matthew’s) many posts on the topic that I have a keen interest in it, as mimicry is not only one of the nicest examples of evolution by natural selection (no, Larry Moran, it can’t be due to genetic drift!), but one that shows how far natural selection can take an animal (or plant), despite various developmental and ecological constraints, to its “optimum”: looking like something else that you know. How close can it get? We know from the leafhoppers and frogmouths we’ve seen that it can get pretty damn close, not to mention Matthew’s blasted nightjars. There are other lessons about evolution to be learned from mimicry, too: things about frequency-dependent selection (polymorphic Batesian mimicry, failure to adapt (the hosts of cuckoos), and so on.

Mimicry is also a good topic for a show-and-tell talk, because there are so many stunning cases of it, which will wow an audience if they have the least interest in biology (just keep reading this site and you’ll see lots more).

And selection can take a species pretty damn close to where it “should” be. Case in point: the leaf fish Monocirrhus polyacanthus from Amazonia, an example I came across while preparing my talk. The fish has evolved both its appearance and behavior to mimic a floating leaf, all to get its prey. They are voracious hunters, and lightning fast in their nomming.

A description from Ichthyologist Tumbler:

An incredibly-adapted species, this fish is camouflaged to mimic a dead leaf, both in body shape and pattern. It can change colour to match its surroundings and has a projection from its bottom lip that resembles a leaf stalk. When hunting, it stalks its prey in a head-down stance, appearing to drift towards it like a dead leaf drifting in a current. When it strikes at an item of prey the entire mouth protrudes outwards, forming a large tube into which the prey is sucked, usually head first. This happens so quickly it is often difficult to see. It can swallow prey almost as big as itself in this way.

A video of their behavior in an aquarium, which is anything but fishlike:

Here’s a video (with very annoying music) showing them hunting and eating:

And a photo of some specimens. The photos on the web show a variety of colors for this species. Notice that not only the mouth but the tail has evolved a point, so that the whole thing looks like a leaf:

I bet you didn’t know that there were leaf-mimicking fish.

The Guardian continues to flog Karen Armstrong’s book

September 26, 2014 • 10:48 am

If it wasn’t already obvious, the Guardian has made clear its view that religion is at worst benign, but in general pretty good. This is clear not only from their continuous atheist-bashing and Dawkins-dissing, but also from their flogging of books that osculate the rump of faith. And they’ve gone overboard with Karen Armstrong’s latest book (Fields of Blood: Religion and the History of Violence), not only giving it a glowing review (the reviewer was Ferdinand Mount), but also publishing a very long excerpt from it online (my printout in Word is 10 pages long).

Armstrong’s book, as well all know, is an attempt to show that religion has never been directly responsible for violence in history, especially wars.  What happens, she says (and I’m taking this from the reviews, as I haven’t read the book yet), is that religion simply gets coopted under the umbrella of politics and culture, which are the real forces behind so-called “religious” violence. Religions, she says, always start out beneficent, but get corrupted when they’re used as instruments of state power. Ergo the violence.

As for the violence in the Middle East, Armstrong claims that it’s all the fault of the West, and not of Islam itself. This of course is the line that Armstrong has dined out on for years.

Well, if you want a précis of her book, go over to the Guardian and read her excerpt, called “The myth of religious violence.” I will reproduce only the last paragraph, which is a typical specimen of Armstrong Apologetics (my emphasis):

After a bumpy beginning, secularism has undoubtedly been valuable to the west, but we would be wrong to regard it as a universal law. It emerged as a particular and unique feature of the historical process in Europe; it was an evolutionary adaptation to a very specific set of circumstances. In a different environment, modernity may well take other forms. Many secular thinkers now regard “religion” as inherently belligerent and intolerant, and an irrational, backward and violent “other” to the peaceable and humane liberal state – an attitude with an unfortunate echo of the colonialist view of indigenous peoples as hopelessly “primitive”, mired in their benighted religious beliefs. There are consequences to our failure to understand that our secularism, and its understanding of the role of religion, is exceptional. When secularisation has been applied by force, it has provoked a fundamentalist reaction – and history shows that fundamentalist movements which come under attack invariably grow even more extreme. The fruits of this error are on display across the Middle East: when we look with horror upon the travesty of Isis, we would be wise to acknowledge that its barbaric violence may be, at least in part, the offspring of policies guided by our disdain.

Right: that’s why ISIS is killing Shiites right and left, as well as infidels. It’s all our fault. I wonder, though, since Armstrong says that ISIS’s violence is “at least in part” due to the West, what might be responsible for the other part? Could it be. . . religion? I doubt she’d agree.  And I wonder what she means by “forced secularisation,” a term that can be stretched so far that it means nothing.

But I have neither the time nor energy to rebut this, nor do I really want to read her book to do so. So I will let Eric MacDonald (who hasn’t read her book either, but knows a lot more about religion and society than I) give his critique. Eric and I of course often cross swords on this site about scientism, but his comment on Armstrong’s book, which you can find at this link, seems quite sound to me.

I’ll quote just his last paragraph (as always, Eric is not sparing with the words!), but read the whole comment:

. . . Certainly, there were economic and political issues in Syria and Iraq that contributed to the rise of armed opposition to the established governments in the region. But Armstrong fails to notice that religion is not a peaceful subtext to these conflicts, and even attracts people who have no connexion with the economic or political issues involved. Thus they become primarily religious wars, in which the original economic and political problems are submerged by religious fanaticism. There is no way to separate the religious and the economic and political factors in the convenient way that Armstrong supposes, and then simply deny that the violence is in any way due to religion, especially when the primary justification given by the leaders of these conflicts is religious.

As I always say, “What would it take to make apologists like Armstrong admit that religion plays a substantial role in the violence?” Clearly it’s not the words of ISIS’s leaders and fighters, who Armstrong must perforce believe are either deluded about their motives or are lying to us—and why would they do that?

There’s no doubt that religion is waning in the West, and has already waned substantially in the UK. That’s why I continue to be surprised at the sympathy that Armstrong’s arguments garner in Britain. In that blessed plot people have left religion in droves, yet they still want to hear only good things about it.

I’m not quite sure why that is. Perhaps some of this rump-osculation comes from former believers who can’t stand to think that religion can be malign, and yet those same people have no trouble singling out the horrors of other ideologies, like Communism and Nazism, that, like religion, are based on irrational faith.

I still have not yet come to grips with why religion, uniquely among all human worldviews and belief systems, is the only one that gets a pass—the only one that you’re typed as “rude” for criticizing.  If you’re a Democrat in the US, you’re not called “strident” for criticizing Republicans. Ditto with the liberals vs. conservaties in the UK. I welcome readers’ theories.

Recommended reading: Sam Harris’s HuffPo column from 2011, “Losing our spines to save our necks.” One quote:

The connection between the doctrine of Islam and Islamist violence is simply not open to dispute. It’s not that critics of religion like myself speculate that such a connection might exist: the point is that Islamists themselves acknowledge and demonstrate this connection at every opportunity and to deny it is to retreat within a fantasy world of political correctness and religious apology. Many western scholars, like the much admired Karen Armstrong, appear to live in just such a place. All of their talk about how benign Islam “really” is, and about how the problem of fundamentalism exists in all religions, only obfuscates what may be the most pressing issue of our time: Islam, as it is currently understood and practiced by vast numbers of the world’s Muslims, is antithetical to civil society.

Guest post: “The mind boggles: four leading UK universities accept creationist pseudoscience diploma as entry qualification”

September 26, 2014 • 8:58 am

by Matthew Cobb

Over at The Guardian, young PhD student Jonny Scaramanga has just given Andrew Brown a lesson in a) how to write a decent article and b) why it is important to oppose creationism—and other pseudoscientific beliefs associated with religion, including in the UK.

Scaramanga was educated at a UK creationist school between the ages of 11 and 14, studying what is called Accelerated Christian Education. He is now researching a PhD at the Institute of Education in London, focused on this pernicious form of religious indoctrination. In his article he explains some of the loonier beliefs foisted on children in these schools. How about generating electricity from snow? That’s right. Here’s ACE’s explanation:

Scientists have known for years that snowflakes are shaped in six-sided, or hexagonal, patterns. But why is this? Some scientists have theorised that the electrons within a water molecule follow three orbital paths that are positioned at 60° angles to one another. Since a circle contains 360°, this electronic relationship causes the water molecule to have six ‘spokes’ radiating from a hub (the nucleus). When water vapour freezes in the air, many water molecules link up to form the distinctive six-sided snowflakes and the hexagonal pattern is quite evident.

Snowflakes also contain small air pockets between their spokes. These air pockets have a higher oxygen content than does normal air. Magnetism has a stronger attraction for oxygen than for other gases. Consequently, some scientists have concluded that a relationship exists between a snowflake’s attraction to oxygen and magnetism’s attraction to oxygen.

Job 38:22, 23 states, ‘Hast thou entered into the treasures of the snow? or hast thou seen the treasures of the hail, which I have reserved against the time of trouble, against the day of battle and war?’ Considering this scripture, some scientists believe that a tremendous power resides untapped within the water molecules from which snowflakes and hailstones are made.

How can this scripture, along with these observations about snowflakes, show us a physical truth? Scientists at Virginia Tech have produced electricity more efficiently from permanent magnets, which have their lines of force related to each other at sixty-degree angles, than from previous methods of extracting electricity from magnetism. Other research along this line may reveal a way to tap electric current directly from snow, eliminating the need for costly, heavy, and complex equipment now needed to generate electricity.

Already in 2009, Scaramanga highlighted the nonsense that the ICCE includes:

One of the textbooks tells pupils: “Have you heard of the ‘Loch Ness Monster’ in Scotland? ‘Nessie,’ for short has been recorded on sonar from a small submarine, described by eyewitnesses, and photographed by others. Nessie appears to be a plesiosaur.

“Could a fish have developed into a dinosaur? As astonishing as it may seem, many evolutionists theorize that fish evolved into amphibians and amphibians into reptiles. This gradual change from fish to reptiles has no scientific basis. No transitional fossils have been or ever will be discovered because God created each type of fish, amphibian, and reptile as separate, unique animals. Any similarities that exist among them are due to the fact that one Master Craftsmen fashioned them all.”

The point of Scaramanga’s recent article is not only to hold ACE’s scientific pretensions up to ridicule, but to sound the alarm in UK universities. Following Freedom of Information requests from the British Humanist Association, it appears that at least four UK universities – we’re looking at you, Bath, Cardiff, Essex and Nottingham – accept the International Certificate of Christian Education, based on the kind of nonsense quoted above, as an entry qualification for university. And this despite the fact that the ICCE is not recognised by the official English qualifications authority, Ofqual.

Head over to Jonny’s article, and to his blog, to read more. It will make your hair stand on end.

And if you work or study at Bath, Cardiff, Essex or Nottingham Universities – these are all highly respectable institutions, with some great evolutionary biology groups – get onto your Deans, Admissions Officers and Vice Chancellors, and ask them why on earth they accept this kind of nonsense as a qualification for university entry.
