Just as filler with your morning coffee, here are two immensely cute spiders. And yes, usually the adjective “cute” doesn’t belong anywhere near the noun “spider”.

The spider in the video is a Spiny Backed Orb Weaver Spider (Gasteracantha cancriformis). They’re pretty small, never getting much bigger than 13 mm. I’m not sure what the top spider is though. Can anyone identify it?

Good morning all! Grania here.

Jerry is already on his way to Poland and will touch down later today. I’m sure he will check in with us as soon as he is able.

Hili: History is a great teacher.
Cyrus: What do you mean?
Hili: In the past after returning home we always had something to eat.

In Polish:

Hili: Historia jest wielką nauczycielką.
Cyrus: Co masz na myśli?
Hili: W przeszłości, po powrocie do domu, zawsze coś jedliśmy.

 

And there is a bonus Leon monologue:

Leon: Did astronomical summer go away?

leon autumn

 

It is indeed distinctly autumnal in parts of Europe today.

 

Today was a busy day in history. In 480 BC it saw the Battle of Salamis (not nearly as funny as it sounds), in 1692 the last unfortunate people convicted of witchcraft in the infamous Salem Witch Trials were hanged. I’d like to think that humanity has gotten better since then, and maybe it has. But not enough yet.

Here’s the Nilgiri Marten!

Many of you got it, but some of you were looking at something else entirely… The Nilgiri Marten has a golden chest, which you can just make out on the far right…

They are cute-looking things, almost second Honorary Cats (though I wouldn’t want to get in a fight with one), as this photo by N. A. Nazeer from Wikipedia shows:

Aditya Gangadharan (aka @AdityaGangadh) posted this pic on Twitter. To give you a hint, a Marten is a mustelid (methinks it is like a weasel), about 50 cm long, with a tail that is slightly shorter. So we ain’t talking nightjars! Click twice to embiggen sans book adverts, comme d’hab’.

Wikipedia claims:

Very little is known about the Nilgiri marten. It is diurnal, and though arboreal, descends to the ground occasionally. It is reported to prey on birds, small mammals and insects such as cicadas.

I was partly attracted to this photo because the Nilgiri Marten is found in the Nilgiri hills in south-western India. For several years, together with ant-expert Christian Peeters, I worked on a population of ant from this region, called Diacamma. Diacamma ants are queenless – they have lost the queen caste, and one worker dominates the others. She is called a gamergate (pronounced gammergate – the word means, or perhaps meant, given that there’s now another meaning, ‘married worker’) and lacks the large ovaries and wings typical of queens.

This situation is typical of many Ponerine ants, but what is weird about Diacamma is that they possess external glands called gemmae – apparently based on wings – that enable them to produce pheromones and to mate. The dominant female hangs around the cocoons waiting for the new ants to hatch out, and she then bites off their gemmae, effectively sterilising her sisters (and later, her daughters). (We studied how this takes place – contact me if you want a copy of the article, as the full article is behind a paywall.)

When the gamergate dies, or the colony splits and half the colony no longer has a gamergate, the first female to hatch out is not mutilated (there’s no one there to do it), so she becomes the new dominant. For pictures of the gemmae go here.

This situation exists in all Diacamma ants, except the Nilgiri population, where no mutilation takes place and the gamergate imposes her dominance physically, as in other Ponerines. This group is not a separate species from the local D. ceylonense, as the two taxa will interbreed (we succeeded in doing this in the lab – a big deal if you work on ants). You can read an abstract from a recent paper by Christian Peeters here.

The scrappy ground seen in the photo is the kind of place you get Diacamma ants – there might even be some mooching around…

 

A Christian spider?

September 21, 2015 • 1:30 pm

Reader Chris sent me a photo of an oddly marked spider and a note:

A few months ago, one Sunday morning, someone knocked on my front door unexpectedly.
(Or did they unexpectedly knock on my front-door? I fear a reprimand from Steven Pinker now.)
I opened the door to be greeted by one of my neighbours, a middle-aged woman I’d never spoken to before, just the occasional friendly smile and hello.
She grinned at me: “I’d like to invite you to a memorial.”
“Sorry?”
“I’d like to invite you to celebrate the resurrection of Jesus”.
Ahh. It was Easter – damn, I need to get chocolate eggs for the kids.
“I’m sorry, really not interested”.
As I closed the door, I swear she scowled at me. Really? You knock on my door uninvited, and it’s me that’s in the wrong?

Yesterday, as I left the house, I nearly walked into a big spider’s web right across my front door.
I took a photo of the offending beast – having zoomed in to inspect further,
I’m pretty sure that neighbour had something to do with this, just look at the cross on its abdomen!
(I presume it’s an abdomen – I wrote ‘back’ initially. Or is it a ‘thorax’?)

Yep, it’s an abdomen, though I can’t identify the punitive beast. But I’m sure some reader can. Chris apparently didn’t realize the money he could make by exhibiting the spider in its web.

UN screws up big time: appoints Saudi Arabian diplomat as head of human rights panel

September 21, 2015 • 11:00 am

UPDATE: For a summary of Saudi Arabia’s abuses, the egregious UN action described below, and the scheduled beheading and subsequent crucifixion of a 20-year old, read the Gatestone Institute’s piece, “Saudi Arabia: World’s Human Rights Sewer.” The country has already executed 79 people this year—every one a “criminal”. (Political prisoners aren’t executed.)

____________

This, as reported by The Independent, is all ye need to know:

The executioners also have the duty to amputate limbs, feet and hands—other barbaric punishments leveled by this supposedly modern country.

UK lawyer David Allen Green, who writes as the Jack of Kent, has a tw**t on the subject. Read the list of punishments carefully.

(The information, which is chilling, comes from here.)

The UN is already soft on anti-blasphemy laws, and now it’s getting soft on human rights. Talk about the fox guarding the henhouse!

Note to readers

September 21, 2015 • 10:36 am

So as not to overload my email when I’m gone, please try to refrain from emailing me too often, though, as always, I welcome “readers’ wildlife” contributions and other items of great interest, for I get most of my good leads from readers.

And bear with me if posting is light for the next few days. After all, I’ll have cherry pie in my stomach and a cat on top of it!

The Atlantic ponders a weighty question: Did early hominins have souls?

September 21, 2015 • 9:15 am

Among the category of Articles That Should Not Have Been Written, this one is prominent. It’s “Did Neanderthals have souls?” by freelance writer Ruth Graham, and her piece is in The Atlantic.

The question of when, and in which species, hominins were “ensouled” is of interest mainly because it’s so dumb, showing not only the conflict between faith and fact, but the silly issues that theologians get paid to grapple with. As shown in the recent book by Julien Musolino, The Soul Fallacy: What Science Shows We Gain by Letting Go of Our Soul Beliefs, there’s not the slightest bit of evidence for a soul. Although a bit repetitive, the book is certainly worth reading, especially for its copious evidence that the mind is a product of the brain and that there’s no bit of “consciousness” that can be detached from the brain and exist separately.

Nevertheless, many theologians not only assert that there is a soul, but that humans are the only species that have one. That, for instance, is the official position of the Roman Catholic Church, which accepts that humans did evolve, but also that we’re distinct from all other species by virtue of our ability to be “ensouled”. Exactly when this happens during embryonic development is not clear, but the ability to be ensouled itself must have arisen during human evolution. And that raises the question of when that ability arrived in our lineage, a question activated by the recent discovery of Homo naledi. (Theologians always need new grist for their mill.)

Such is the subject of Graham’s piece, which would be okay if it mentioned the evidence against souls. But it doesn’t: it simply buttresses the superstition mongers who find the evolutionary arrival of souls is an intriguing and viable question. But that question is completely unanswerable, not only because we almost certainly don’t have souls, but because the concept of a soul is itself so nebulous that we wouldn’t know what kind of evidence to accept. Should we take ritualistic burial of the dead? (H. naledi may have deposited the dead in a burial chamber, but some ants do the same thing) Religion itself and worship of deities? Language?

Here are the questions, discussed by Graham, that the concept of a soul raises for its adherents:

The broader issue is what happens to the soul of anyone born before Jesus Christ. Surely Moses and Abraham, for example, made it to Heaven. But how? The short answer, according to many theologians, is they trusted in God’s promises about the coming of a savior. They wouldn’t have known the specifics about Jesus Christ of Nazareth, but they could have had a general faith that a Messiah was on his way.

A related question is what happens to modern people who never had the chance to hear the message of Jesus Christ. Again, most Christian theologians allow for salvation on the basis of a kind of orientation toward God. Here’s how the Catholic Church’s Second Vatican Council addressed the problem in 1964, for example:

“Those also can attain to salvation who through no fault of their own do not know the Gospel of Christ or His Church, yet sincerely seek God and moved by grace strive by their deeds to do His will as it is known to them through the dictates of conscience.”

That last sentence is the kind of opaque theobabble that the Vatican regularly emits.

These are prime examples of the silliness of theology, which answers these questions by simply making stuff up. It always amazes me that educated people can even bother themselves with these questions, much less write screeds about them. (See, for example, the book The Soul: How We Know It’s Real and Why It Matters, by J. P. Moreland, or the article in Psychology Today by physician/researcher Robert Lanza, “Does the soul exist? Evidence says ‘yes'”, which takes as evidence the existence of subjective experience.)

To some theologians, the question of whether H. naledi has a soul comes down to this: “Was the species descended from Adam and Eve?” Since the scientific evidence shows that H. sapiens could not have descended from only two individuals, this question is already nonsensical. But creationist Kurt Wise (remember him?) sees it as answerable, and with a “yes”:

Creationists are already arguing over the naledi discovery. Kurt Wise, the director of the Center for Creation Research at Truett-McConnell College, told the evangelical World magazine that the fossils do represent a fully human species.

But the equally fundamentalist group Answers in Genesis, headed by Ken Ham, disagrees, claiming that H. naledi wasn’t descended from Adam and Eve. They were just apes!

These fossils, like so many others before them, may reshuffle the “family tree” that evolutionists are constantly drawing and re-drawing in their efforts to create for us a history apart from God. But they will not re-shuffle the truth about human history or what it means to be human. We know that God created man and land animals the same day without evolution. We seriously doubt the original owners of the Dinaledi bones [H. naledi] were among the descendants of Adam and Eve, as the preponderance of the evidence suggests they were animals, one of the variations that developed among apes. They most certainly were not any sort of evolutionary intermediate.

This is ludicrous, of course, because we’re still apes, and we’re certainly animals! Here we have two fundamentalist Christian groups disagreeing, with no way to settle the issue. Instead of suspending judgment pending a good definition of the soul and a way to demonstrate its existence, they just make stuff up. This is not science but wish-thinking, and it’s no way to settle issues. And remember, this is in principle an empirical question: it’s about religion asserting what’s real, not simply dealing with meanings and values. So much for those who bang on about religion not making any claims about reality.

But of course even more liberal theologians accept souls, and thus still must deal with the evolutionary question. Graham continues:

Even the many Christians who accept that the world is much older than 10,000 years find that the problem can still provoke. But it’s not necessarily cause for despair over the fate of the naledi soul. British pastor Mark Woods, a contributor to the online publication Christian Today, wrote recently that the naledi burial site raises intriguing suggestions for Christians about the existence of the soul. If this primitive group went to such lengths to bury their dead, he argues, it “shows they knew that death was not an absolute ending, and that those who had died were still, in some way, present.”

That’s a theological way of saying what scientists have been arguing all along. As Lee Berger, who led the discovery in South Africa, put it, “We are going to have to contemplate some very deep things about what it is to be human.” For some, it’s a matter of eternal life and death.

Re the first paragraph, we still don’t know whether the cache of H. naledi skeletons represents some kind of ritual, much less any behavior suggesting that those dead were considered “sacred.” Some ants remove their dead and put them in a “death pile.” Does that mean that ants have souls, too? There’s no evidence that the naledi dead were buried: they could have simply been removed to a specific location in the cave—and really, we don’t even know that for sure. And even if they were buried, this could have been just to avoid stench and contamination. Finally, even if they were buried deliberately for spiritual reasons, that doesn’t show H. naledi KNEW that “death was not an absolute ending.” It showed at most that they believed it. Here pastor Woods is mistaking belief for fact.

As for Lee Berger’s statement, I still think it’s silly to ponder “what it is to be human”, at least on the basis of his discovery (he headed the team that found H. naledi). Let Berger first answer the slippery question of what we mean by “fully human”—and that, of course, is completely subjective. If we invoke specific things like behavior or brain size, yes, we can in principle get an answer. But that’s not what many secularists mean: they are surely talking about the subjective beliefs and attitudes of hominins, and that question is almost impossible to answer.

And it becomes completely impossible to answer once we begin invoking theistic concepts of the soul. If the human soul is a requirement for being “fully human,” and the soul is an idea without an iota of supporting evidence, then the question will linger forever in the domain of theology: a discipline that cannot truly answer its questions, but pretends to do so by confecting solutions.

As for Graham, it was her journalistic responsibility to point out the lack of evidence for souls, and certainly to quote someone who thinks the whole question is nonsensical.  By quoting Berger in her last paragraph as almost supporting souls, Graham simply keeps the question alive. If we’re going to talk about “what it means to be human”, let’s get tangible about the question, honest about its subjectivity, and dubious about our ability to find answers.
