A bit late to the party- but this is one of the finest papers I have read in years. It is both super cool science, and does the near impossible in our field: grounding insights about the evolution of molecular mechanism in the ecological arena in which they (presumably) arose. It's a masterpiece.
Researchers in the US might be having feelings about writing grants atm-I know I am!
We still need to write them. In this Evolution Exchange, I again chat with Sam Scheiner, who summarizes how to write a competitive proposal.
His advice is gold, and helpful regardless of funder. Pls RT!

Bimbo!
We’re coming for the record!
I haven’t really spent that much time playing with 4.6, but it seems similar to 4.5. Which is an incredibly good model.
I’d watch that!
Yes. But he’s playing both roles.

It was an amazing trip. A picture from our stroll through Lausanne’s vineyard region, as well as the other side of the fondue pot!
Thanks again for hosting me Omaya!
If you liked this experiment, I published a full piece today in the same vein: a text that gets 100 years older with every section, from a modern blog post to a medieval chronicle.
It's a single story spanning 1000 years of English. See how far you get.

Damn it what mischief are my kinfolk up to?!
Wow, Michael, thank you so much for the detailed questions and also kind words!
I think most of these questions are unanswered, but will be major areas of exploration over the coming century. The closest I know is this: www.pnas.org/doi/full/10....
Seems to fit your central hypothesis!
Cooperation is a universal feature of complex systems, from the origins of life and microbiomes to societies. What universal patterns can be found in these systems? Here's our new @pnas.org paper. @jordipinero.bsky.social @artemyte.bsky.social @sfiscience.bsky.social www.pnas.org/doi/epdf/10....

New paper out - fun collaboration with @wcratcliff.bsky.social & led by the wonderful Tony Burnetti! IMO, a rare clear example identifying the mechanism underlying priority effects at macroevolutionary scales. Also, continuing to justify my PhD from a plant lab 🍃

It was domesticated there!
Dang, I don’t know- if only Tony Burnetti were on BlueSky!
Good q! They don’t!
All rhodopsin based critters are either heterotrophs (and use rhodopsin as a facultative energy source) or also have chlorophotrophy too.
Very cool! I’ll have to watch when I’m not chaperoning a field trip of rambunctious 5th graders!
He’s one of a kind!
Sweet. Would love to chat about some time! You should talk with Tony too, this paper is absolutely his brainchild!
Yes! Only chlorophototrophs can fix carbon, which opens up totally different niche opportunities! Rhodopsins are like a little supplemental solar panel for a heterotroph.
Thanks man!
I think it still fits. The cyano hasn’t evolved a third type of photography has it?
I love this idea! I’d be game.
28/28 As always, we'd love to hear your thoughts. Thanks for sticking around to the end!
27/28 More broadly, this framework may apply to other apparent "evolutionary singularities." Eukaryogenesis. The origin of life itself. The evolution of animals. Events that happened once might not be improbable: they might simply have created priority effects that prevented repeats.
26/28 If proto-chlorophototrophy appeared in a world with established retinalophototrophs, it could escape competitive exclusion by occupying the carbon fixation niche, something rhodopsins are chemically incapable of doing. Then it had time to optimize for energy metabolism too.
25/28 This raises another question: why didn't whichever system evolved first simply exclude the second? Our model suggests retinalophototrophy likely came first. Here's why: chlorophototrophy can fix carbon. Rhodopsins cannot.
