Let’s start the morning with something cheery. Here’s an innocent little ciliate swimming about and then rupturing…organelles and cytoplasm spewing into the medium…and it struggles to hold itself together and the remnant swims away…to no avail. It finally just disintegrates.
Definitely a hard death.
Don’t cry. It doesn’t have a nervous system or consciousness.
I’m getting together with some nerds, Jackson Wheat, Phrenomythic, and ScientistMel, to talk about the challenges of communicating science on YouTube, a medium which seems to favor posturing twits, Nazis, and Nazi twits more than it does people with actual content. It’ll be a public conversation at 5pm Central time today, right here:
If you have your own questions and comments, leave them here, or tune in and leave them in the chat. Another thing: there are successful science youtubers out there. I have a long list, but if there are others you want to call attention to, let me know!

This is funny, but I have never seen a bolas spider. Have you?
They’re on the checklist of Minnesota spiders, though, so they exist this far north. I’m going to have to make finding one an objective of my summer research plans. They’re nocturnal, though — I might turn into that weird guy poking around in the neighborhood bushes and trees late at night. I swear, officer, I’m not a peeping tom, I’m just looking for arachnids.
Hmm, the cemetery might be a safe place for nocturnal spider watching.
Michael Behe has this new book out, Darwin Devolves. I haven’t been able to muster enough enthusiasm to even want to try and dissect it — that man has been shitting on science for at least 20 years now, and having picked through his fecal piles before, I know what to expect, and am tired of it. He is tediously predictable.
Fortunately, Gregory Lang and Amber Rice have the willingness to do the dirty work and dive right in and sift through the shit in this excellent review, Evolution unscathed: Darwin Devolves argues on weak reasoning that unguided evolution is a destructive force, incapable of innovation. They discover that Behe cherry-picks his evidence, ignoring, or worse, being completely ignorant of, vast orchards of information that directly refute his premise, which Lang and Rice cite and summarize. It’s an informative review. Go read it, I won’t rehash it. You’ll learn a lot from it.
I will mention the conclusion, which discusses the peculiar tension at the heart of the evolution/creation argument. I did highlight one sentence.
Without a hint of irony, Darwin Devolves cautions us that “[t]he academic ideas of nutty professors don’t always stay confined to ivory towers. They sometimes seep out into the wider world with devastating results (p257).”
Scientists—by nature or by training—are skeptics. Even the most time-honored theories are reevaluated as new data come to light. There is active debate, for example, on the relative importance of changes to regulatory versus coding sequence in evolution (Hoekstra and Coyne 2007; Stern and Orgogozo 2008), the role of neutral processes in evolution (Kern and Hahn 2018; Jensen et al. 2019), and the extent to which evolutionary paths are contingent on chance events (Blount et al. 2018). Vigorous debate is part and parcel of the scientific process, lest our field stagnate. Behe, however, belabors the lack of consensus on relatively minor matters to proclaim that evolutionary biology as a whole is on shaky ground.
By reviewing Behe’s latest book, we run the risk of drawing attention—or worse, giving credibility—to his ideas. Books like Darwin Devolves, however, must be openly challenged and refuted, even if it risks giving publicity to misbegotten views. Science benefits from public support. Largely funded by federal grants, scientists have a moral responsibility (if not a financial obligation) to ensure that the core concepts of our respective fields are communicated effectively and accurately to the public and to our trainees. This is particularly important in evolutionary biology, where—over 150 years after On the Origin of Species—less than 20% of Americans accept that humans evolved by natural and unguided processes (Gallup 2014). It is hard to think of any other discipline where mainstream acceptance of its core paradigm is more at odds with the scientific consensus.
Why evolution by natural selection is difficult for so many to accept is beyond the scope of this review; however, it is not for a lack of evidence: the data (only some of which we present here) are more than sufficient to convince any open-minded skeptic that unguided evolution is capable of generating complex systems. A combination of social and historical factors creates a welcoming environment for an academic voice that questions the scientific consensus. Darwin Devolves was designed to fit this niche.
Creationists like to pretend that there is still a legitimate debate here, and their absurd confidence does seem to be effective in swaying, as they mention, about 80% of the population. In response to their ignorance, responsible scientists are expected to invest a great deal of effort in reacting to stupidity. It is ten thousand times harder to master the science behind evolutionary biology than it is to read a few bible verses and some clueless apologetics and decide that the science is all wrong. Behe, and people like him, are ridiculous crackpots, and we’re saddled with the obligation to refute them.
And yet we do. Or Lang and Rice do. I’m sitting this one out, which makes me immensely grateful that more scientists are joining in the battle.
I was just reading about these recently identified genera of Central and South American mygalomorph spiders, Paratropis and Stormtropis, and got a little thrill from the photos, so I had to share. Their eyes are mounted in a little turret-like structure bulging up above the cephalothorax, and when you flip them over, oooh, those fangs. All black and pointy.
I know some of you don’t get that excited about spiders, especially ones that hairy and weird-textured and equipped with especially prominent bitey gear, so I’ll hide them below the fold.
Today I got all curmudgeonly about a stupid science fiction trope: the response to an environmental catastrophe that involves abandoning the planet to colonize Mars, or Titan (!), or some other mysterious planet, as if it’s just like leaving Sweden on a boat to start a farm in Minnesota. It’s pernicious, and leads to stupid decision-making.
I am extremely impressed with this creator’s video editing skills. Nicely done!
I am less impressed with the content, unfortunately. The message is pure optimism: our progress in biology is so great that maybe someday we can hope to cure a host of psychological concerns, like anhedonia, misery, self-doubt, etc., with…gene editing. Got low self-esteem? Frustrated by the world around you? Finding yourself unsatisfied no matter what successes you achieve? We can fix that, someday! We’ll just reach into your genome and snip out the bits of DNA that make you question your happiness, and replace them with genes that’ll give you joy, no matter how miserable the world is making you.
Well. I guess you could aspire to that, but it sounds very 1984 to me. Maybe I like being who I am, and don’t think that jacking up my sensation of happiness artificially is entirely desirable. There are drugs I can buy right now that will enhance my contentment with things as they are without meddling with my genome in a permanent way, but I don’t think elevated bliss is necessarily the purpose of my existence.
But set all that aside. Why would anyone think your satisfaction with the status quo is genetic? This is naive biological reductionism and genetic essentialism in raw form. I’d recommend learning some real genetics, molecular biology, and neuroscience, except that if your goal is happiness regardless of the circumstances, maybe artificially maintained ignorance is what you need.
I’ve been playing with a few other species, and now I really want a cat-sized salticid for a pet.
It’s not a shot of cold water in the face…more like a blast of super-heated steam. Yeah, this article on our prospects for global climate change is the most terrifying thing I’ve read in ages.
The present tense of climate change — the destruction we’ve already baked into our future — is horrifying enough. Most people talk as if Miami and Bangladesh still have a chance of surviving; most of the scientists I spoke with assume we’ll lose them within the century, even if we stop burning fossil fuel in the next decade. Two degrees of warming used to be considered the threshold of catastrophe: tens of millions of climate refugees unleashed upon an unprepared world. Now two degrees is our goal, per the Paris climate accords, and experts give us only slim odds of hitting it. The U.N. Intergovernmental Panel on Climate Change issues serial reports, often called the “gold standard” of climate research; the most recent one projects us to hit four degrees of warming by the beginning of the next century, should we stay the present course. But that’s just a median projection. The upper end of the probability curve runs as high as eight degrees — and the authors still haven’t figured out how to deal with that permafrost melt. The IPCC reports also don’t fully account for the albedo effect (less ice means less reflected and more absorbed sunlight, hence more warming); more cloud cover (which traps heat); or the dieback of forests and other flora (which extract carbon from the atmosphere). Each of these promises to accelerate warming, and the history of the planet shows that temperature can shift as much as five degrees Celsius within thirteen years. The last time the planet was even four degrees warmer, Peter Brannen points out in The Ends of the World, his new history of the planet’s major extinction events, the oceans were hundreds of feet higher.
It gets worse from there. Much worse.
Future generations — I mean, the current generation — will look back on this time and regard all those Republican climate change deniers as monsters committing crimes against humanity, and the rest of us as lazy good-for-nothings who couldn’t get off our butts to arrest the liars and frauds and greedy, corrupt short-term thinkers who are busily wrecking the planet for our species.
But wait, you say, didn’t Trump recently bring on a science advisor, at last? Isn’t he a scientist of some sort? Of some sort, sure — Kelvin Droegemeier is a weather man with no knowledge of climatology, but he has some credentials. If you think he’ll be a voice of reason in the White House, watch this and be disillusioned.
That was a truly masterful demonstration of cowardice and evasion — he’s got no spine at all. If he doesn’t die of natural causes first, our descendants are going to have his wobbly, worthless head on a pike, and he’ll deserve it.
Arielle Duhaime-Ross, the interviewer, is good and persistent, though, not letting him off the hook at all. I wish more journalists would do that.
I should let you know about this article, The ultimate lovely legs competition: the world’s nine most beautiful spiders, although I’m not too thrilled with the premise. It’s not a competition, all spiders have lovely legs…and chelicerae and eyes and abdomens and cephalothoraxes.
(I didn’t include any photos in this post because I’ve learned that some of you get so overwhelmed by the beauty that you close your eyes or close the browser window and go have a nice lie-down, and I didn’t want to disturb your work flow.)
