Lex Friedman had an evolutionary biologist on his podcast, sometime in the last few months. The way he explained it was that the accumulation of simple mechanisms trend towards the more complex mechanisms via gradients, electron affinity, etc. I believe it was with Michael Levin, but I can’t play the audio to confirm right now.
I’ve had the opportunity to work with quite a few patients that were born with anatomical structures where they shouldn’t be or oriented abnormally (e.g. Apert syndrome and dextrocardia). It’s fascinating stuff from a biological standpoint.

DNA has a carbon backbone!? Next you’re going to claim the Earth isn’t flat

Side question, what’s happening biologically when a patient begins to “sundown”?
Worked geriatrics for 2 years and it was like clockwork with certain folks. I always assumed it was issues with signals in the pituitary

Reply to comment by regular_modern_girl in Why does alcohol kill bacteria, but not the cells that our bodies are composed of? by Chairman_Mittens
Aren’t certain types of bacteria more resistant based on their cell membrane composition? Like gram-positive vs gram-negative or acid-fast bacteria?
Not saying they’re immune but stain retention after ethyl alcohol washes would indicate its membrane is less permeable with regards to ethyl, right? iirc the thickness of the layer peptidoglycan in gram-positive cells allows for simple stain retention; mycolic acid in acid aids in stain retention after acid-alcohol washes

Reply to Hyperion is the largest of Saturn's irregular, nonspherical moons. Hyperion's mean radius is 135 km, but as it's potato-shaped, its shape can be described in terms of its diameter along its three axes: 410 x 260 x 220 km. Credit: NASA/JPL/Caltech/SSI by MistWeaver80
It’s clearly a giant egg, possibly space Godzilla?
