I teach chemistry and evolutionary biology... on the internet.
People keep asking why this flagella model looks like ramen noodles. Here's why: @smartereveryday.bsky.social
Co-evolution is a beautiful thing! See more in the full video here: youtu.be/fguLh2deMz0
I once tried to fix my bicycle but found it to be a really hard problem. At first I was frustrated but then I realized that if someone as smart as me can’t figure out bicycleness, that must mean the entire universe IS bicycle! #Panbicyclism.
The animation I'm working on shows how flagella work and assemble. I'm very excited!
I just want you to know that when I got my @dragonsofwales.bsky.social book, I was so excited I cut myself opening the package! Worth it! www.etsy.com/ca/shop/Drag...
It's on track to be published April 6th. See the teaser now: www.patreon.com/posts/teaser...
Some critters from this year's #EvoTour in the Amazon Jungle with @scibugs.bsky.social (she can do custom tours for you or your group too on scibugs.wetravel.com) Can you name all the species, or at least the genera?
I have hundreds of photos to share from this year's Evolution Tour in the Amazon jungle, but first, shout-out to @scibugs.bsky.social for finding us a neon pink Jesus bus! I love that this exists!
I made this for my interview with Dr. Juliet Turner. Video is out soon!
This X-ray of a Komodo dragon is rad! That is all. www.mdpi.com/2076-2615/13...
Scientist: "This remains an active area of research and ongoing empirical exploration." Napoleon Dynamite translation: "We don't flippin' know yet but we're trying. Jeez!"
This lizard is pregnant! I talk about it in the new Stated Clearly animation: Darwin's Monster youtu.be/CHvclYKy85w?... These photos are by Dr Rebecca Pyles who studies the evolution of pregnancy and live-birth in reptiles.
Note to #ScienceTeachers, the new animation now has NGSS categories added to it. HS-LS4-1: Communicating Common Ancestry HS-LS4-2: Process of evolution HS-LS4-4: Natural selection and adaptation. www.statedclearly.com/videos/darwi... #biology
Snake biologists: How do you feel about where I set the "certainty-o-meter" here for the burrowing snake (Fossorial) hypothesis? Should I have it higher, lower? Side note: The scale was drawn for me by @jordancollver.bsky.social years ago. I added the gauge today to illustrate confidence levels.

Okay, I know that right now is not the best time in history to criticize scientists, but seriously? Why is this diagram in a real paleontology article about limb evo? They mix pectoral & pelvic fins. Each illustration has a different style. I'd get fired for this shit & I'm a YouTuber.
Ha! This was emailed to me today by a fan: "Leaked photo of Colossal's resurrected Dodo bird"
My dog has a teddy bear he brings with him everywhere. He uses it, not to snuggle, but to practice murdering.
I love Gila Monsters. Their shape is so... potato? But then they're covered in beads! @jordancollver.bsky.social did you ever draw one? I feel like you'd be the best at noticing all the things about them that must be appreciated and put into ink!
RFK Jr claims we have measles outbreaks every year. Is he correct? Turns out he is. Here's the CDC data: www.cdc.gov/measles/data... Does this calm you or do you still worry he's downplaying the significance? It does look like we're headed into a rough year but hopefully not like 2019.
I asked ChatGPT to do a deep research response on leg loss in snakes and parallel evolutionary in other reptile groups. It read a bunch of papers and tried to supplement with popular articles. Turns out that our new robot overlord has great taste in science blogs! @tetzoo.bsky.social.
Trait duplications (serial homologies) happen all the time in evolution. The 4 horned antelope is the only bovid species with 4 horns. It's not clear if they evolved from a single mutation (as in 4 horned sheep) or evolved gradually from a pronged horn.
Law and order is essential but this is not a celebration of law and order, it is the institutional celebration of suffering.
I keep seeing biologists claim they've falsified the (poorly named) "central dogma" by finding proteins that cause mutations. No. To actually defy the "central dogma" you need a natural system that reads protein sequences & converts them to DNA sequences. Search on, my friends!
This art is from the first paper modeling the structure of double stranded DNA. It was Drawn by Odile Crick (married to Francis Crick) & based on the X-ray diffraction data of Rosalind Franklin. I love it! It shows the major & minor grooves, correct chirality & approximate number of bases per turn.
