Spider skeleton

It must be convenient to be a spider at Halloween. To decorate, you just rummage through your closet and pull out an old molt — instant skeleton!

The good news, too, is that my latest generation of spiders are growing up, and starting to molt. Here’s a shed spider cuticle I found today.

They shed by popping open the top of their head, which you can see at the top left, and then back out, pulling their legs up out of the old limbs. I keep hoping to catch them in the act, but I think they do it in the middle of the night, to minimize the danger while defenseless.

I put a picture of her post-molt down below.

Do you like to play games?

A few news items:

  • I sometimes play on Sitosis, a free public Minecraft server. It’s totally vanilla, with a mature user base, and has been wonderfully free of drama and griefing — I strongly recommend it, if you’re into that game.
    But did I say “free”? Someone has to pay for the server, and that requires voluntary donations. If you play there, and you can afford it, it’s time to pay for the hosting, and they’re looking for a little bit of money to keep it going.
  • Lately I’ve been playing a little bit of No Man’s Sky, a space exploration game with a bit of minecraft-style creative construction thrown in. I live-streamed it last week, and I’ll be up to mischief again on Friday night.

    I’ve also been thinking a bit about that Netflix show, Alien Worlds, and that it has a lot in common, both strengths and weaknesses, with NMS. I’ll probably babble a bit about that while I build a primitive shack on a strange planet.
    By the way, there is some obnoxious interaction between NMS and Linux that I haven’t been able to track down that does funny things to the sound. I’ll probably sound like I’m inhaling helium the whole time, for extra fun.

Palpable desperation and schadenfreude

One of the things bringing me great joy right now is watching QAnon implode. None of the predictions came true! It was all a lie! It’s sinking in for some.

Despite attempts to keep the hope alive, QAnon followers watched in dismay as Trump left Washington, D.C., for Florida Wednesday morning while Joe Biden was sworn in as the 46th president of the United States. With no military coup, no dramatic scenes of revolution, and no mass executions or retaliatory violence as prophesized, QAnon adherents began to wonder if they had been deceived.

“It’s over. We were played,” one follower said on a QAnon Telegram channel with more than 30,000 subscribers. “I’m going to throw up now.”

“[Q] has left me here looking out over the sea watching and waiting,” a QAnon disciple said on Telegram. “No word, no letter, no sign. Nothing tangible on which I can depend. I could wait forever but no true sign.”

“I’m crying and tired of this pain,” said one post on a QAnon channel. “All the evil is being praised right now while we sit and watch. No arrests, no swamp reveal. Nothing.”

With Biden officially inaugurated, one QAnon follower was clearly disgruntled. ​“We all got arse fucked,” ​he told the channel.

It’s great that I can laugh now, but these people haven’t changed. Give them time, and that gullibility and loony conspiracy thinking will have to bust out somewhere else. That’s already happening, and this is ominous:

Some QAnon channels attempted to maintain optimism by theorizing that “Biden will be the one who pulls the trigger” that leads to “The Storm”, that “Biden is Q,” and even that the 17 flags at Trump’s farewell speech—Q is the 17th letter in the alphabet—was a sign to “trust the plan.”

No, no, no — you’re supposed to have learned to be more skeptical, not to reach harder for goofy rationalizations.

The Pelagian Heresy? Really?

I can tell we’re going to be hearing much about young Mr Josh Hawley in the future. He’s a fanatical Christian dominionist of the worst kind, and as Katherine Stewart explains, he has a guiding philosophy. He blames every thing wrong in society on Pelagius.

In multiple speeches, an interview and a widely shared article for Christianity Today, Mr. Hawley has explained that the blame for society’s ills traces all the way back to Pelagius — a British-born monk who lived 17 centuries ago. In a 2019 commencement address at the King’s College, a small conservative Christian college devoted to “a biblical worldview,” Mr. Hawley denounced Pelagius for teaching that human beings have the freedom to choose how they live their lives and that grace comes to those who do good things, as opposed to those who believe the right doctrines.

The most eloquent summary of the Pelagian vision, Mr. Hawley went on to say, can be found in the Supreme Court’s 1992 opinion in Planned Parenthood v. Casey. Mr. Hawley cited Justice Anthony Kennedy’s words reprovingly. “At the heart of liberty,” Justice Kennedy wrote, “is the right to define one’s own concept of existence, of meaning, of the universe, and of the mystery of human life.” The fifth-century church fathers were right to condemn this terrifying variety of heresy, Mr. Hawley argued: “Replacing it and repairing the harm it has caused is one of the challenges of our day.”

When I first read about Pelagius lo these many years past, I thought it was a shame that his ideas hadn’t taken root in the early church, but I didn’t suddenly become a faithful adherent of Pelagianism. It’s pure projection on Hawley’s part to think that people come to their beliefs about life by picking an ancient Holy Man and following him. I rejected religion because of the batshit crazy ideas it promotes, rather than because I found a 4th century monk who said things I liked.

The craziest idea that repelled me was this whole notion of “faith, not works”. It didn’t matter what you did in life — go ahead, murder and steal and violate the ten commandments all you want, as long as you accept Jesus in your heart on your deathbed, you will be welcomed in heaven. We are all sinners, bad and wicked, and pretending to be a good person won’t save you, only your belief in gods matters. Or rather, professing your belief to the benefit of the church and priesthood is what matters.

And that’s the rotten heart of most flavors of Christianity. Thanks, Augustine!

In case you’re looking for a more thorough definition of the Pelagian Heresy, read on.

Pelagianism rejects several basic Christian doctrines. First and foremost, Pelagianism denies the doctrine of original sin. It rejects the notion that because of Adam’s fall, the entire human race was contaminated by sin, effectively passing sin down to all future generations of humanity.

The doctrine of original sin insists that the root of human sinfulness comes from Adam. Through the fall of Adam and Eve, all people inherited an inclination toward sin (the sinful nature). Pelagius and his immediate followers upheld the belief that Adam’s sin belonged to him alone and did not infect the rest of humanity. Pelagius theorized that if a person’s sin could be attributed to Adam, then he or she would not feel responsible for it and would tend to sin even more. Adam’s transgression, Pelagius supposed, served only as a poor example to his descendants.

Pelagius’ convictions led to the unbiblical teaching that humans are born morally neutral with an equal capacity for either good or evil. According to Pelagianism, there is no such thing as a sinful disposition. Sin and wrongdoing result from separate acts of the human will.

Pelagius taught that Adam, while not holy, was created inherently good, or at least neutral, with an evenly balanced will to choose between good and evil. Thus, Pelagianism denies the doctrine of grace and the sovereignty of God as they relate to redemption. If the human will has the power and the freedom to choose goodness and holiness on its own, then the grace of God is rendered meaningless. Pelagianism reduces salvation and sanctification to works of human will rather than gifts of God’s grace.

Well gosh, when you put it that way, I guess I am sort of a Pelagian! I’m not interested in joining a Pelagian church, but more that I find the standard Christian theology of humans being intrinsically evil who can only be saved by worshipping a deity to be morally repugnant. I guess that Hawley is correct to consider me and my kind to be the enemy.

He’s still wretchedly wrong about everything, though, so let us join battle with the adversary.

Someone is really pissed off at the election results

It’s God. I mean, Ken Ham, who thinks he is god.

Oh look. Biden has appointed a transgender woman to a position where she can advise godly men. This is catastrophic to the Christian world view.

Once again, he demonstrates that his peculiar interpretation of the Bible is the one true Christianity.

OH NOES. Biden is planning to sacrifice children on the altar of secular humanism! Darn these Moloch worshippers worming their way into high office.

Wait, I thought he was a Catholic…

Today at 3 central time, EVO-DEVO

I’m going to put off the celebratory imbibery a bit longer today so that I can talk about development of the nervous system.

I’ll be stone cold sober, but I might still be a little giddy. I’ll be discussing “Evolving specialization of the arthropod nervous system”, published in PNAS in 2012, sort of — there’s lots of good stuff in there, but I might dwell on neurectoderm formation a bit longer than Jarvis, Bruce, and Patel. Because it’s cool.

Last call: if you want join me over Zoom, send me an email, maybe I’ll send you a zoom link. Otherwise, feel free to join the YouTube chat!

HE’S GONE!

He gave a farewell speech in which he blamed all the deaths on his watch on China, declared that his administration had given Biden a good foundation (he’s going to claim credit for any good that emerges in the next few years), threatened to be back “in some form” in the future, and then boarded a helicopter and flew away as Fox News played YMCA (???).

LET THE REJOICING BEGIN! No, not you, Joe. Get to work.

By the way, while you might want to sigh with relief that you made it through the last four miserable years, remember that 400,000 didn’t. They weren’t killed by China, either — they were murdered by Republican incompetence. Destroy that party. That’s your new mission.

If you must, here’s a bit of his speech, and that surreal send off to the tune of YMCA.

Now we wait for reality to slap his fans in the face, hard.

It is appropriate that today I would be reading about a fossilized dinosaur butthole

Nice. Paleontologists found a fossil Psittacosaurus with beautifully preserved scales — they can even see signs of the pigments coloring it — and best of all, they found a perfectly preserved cloaca.

The Frankfurt specimen of Psittacosaurus sp. (SMF R 4970) from the Early Cretaceous Jehol deposits of Liaoning exhibits the best preservation of scale-clad integument in any non-avian dinosaur yet described. Preservation of colour patterns and countershading allowed a detailed reconstruction of this individual’s physical appearance suggesting it was camouflaged for life in a shaded lighting environment. It was previously noted that the cloacal region was preserved2, but its detailed anatomy was incorrectly reconstructed. We show here that the fine anatomy of the vent is remarkably well preserved and can be retrodeformed to illustrate its three-dimensional nature. The vent’s scale anatomy and pigmentation are distinct from adjacent body regions, and although its anatomy does not reveal much information about the ecology, or sex, of this dinosaur, it suggests possible roles for visual and olfactory signalling.

The caption to this figure is messed up. The top half, labeled A, is “Cloacal vents across the tetrapod phylogeny”. The text below refers to the bottom half only, and should be specifying B, C, and D rather than A, B, and C. Looks like a job for an editor.

(A) Cloacal vent region preserved in Psittacosaurus sp. SMF R 4970, photographed with crossed polarised lighting. The specimen is exposed in oblique (right) latero-ventral view. The ischial callosity is defined by its bulging appearance on top of the ischium, having large, rounded scales that are heavily pigmented centrally but become lighter marginally. Posterior to the ischial callosity is the cloacal vent, partly obscured by a preserved coprolite and rock breakage. The lateral lips are defined by their distinct outline, indicated by relief and break of slope due to overlap, and are covered by highly pigmented and overlapping scales with lighter margins (Figure S1C,D). (B) Interpretative drawing of the same region as in (A). (C) 3D reconstruction of the cloacal vent in lateral view. (D) Phylogeny of tetrapods illustrating the diversity of cloacal vent morphologies. Two alternative reconstructions are presented for Psittacosaurus sp. depending on whether the cloacal opening forms a slit onto the dorsal lobe, as in crocodylians (ii), or a rounded hole between the lateral lips, as in birds (i).

The Noah’s Ark/DNA guy is back

Earlier, I posted those emails from a creationist telling me that he had a “theory” that united human genomics and Noah’s ark. I told him I was uninterested in the conversation. Of course, he wouldn’t shut up and sent me another email today.

Hello,
Yesterday I sent you my theory on human genetics and Noah’s Ark. Today, I am sending you the theory again in hopes that you’ll read it. It only takes 10 minutes of your time and it’s finding may be life changing. If you will just suspend your disbelief and are willing to entertain the idea that everything we know is wrong, you may find this theory interesting. I am a college graduate in the field of Biology and a former atheist/evolutionist. I am well studied in the theory of evolution as well as new atheism, so I understand this idea might seem absurd at first. However, with an open mind this theory will be life changing.

I’ll give you his “evidence” now. First of all, there is no theory to read: he sent me a pdf titled Theory that is nothing more than a list of biblical patriarchs and the haplogroups he assigns to them. That’s it! A list is not a theory.

To make it even worse, he sent an assortment of images organized by each of the biblical patriarchs — photos of modern people of different races. This is also not a theory. (I’m not attaching that here — it’s pointless.)

Then he sent a map of “Noah’s World”, showing the imaginary migration routes of Noah’s descendent. It’s a map. Not a theory.

And finally, there’s a Y DNA haplogroup map. Not a theory.

My life has not changed, and I don’t find the “theory” very interesting. It is absurd. And stupid.
