Should also say i thougt all the other findings were interesting and convincing, nice work!

Also, although many current eukaryotes need a high ATP production rate to maintain their expanded genomes, FECA/LECA likely not yet needed that, as it's genome may still have been relatively small, like current Archaea and many current protists or fungi. Just my 2 cts

@archaeal.bsky.social, I have reservations about the conclusions of this paper because of muddling kinetic and stoichiometric aspects. Yes micropcompartments can boost rates but that will never affect energy yields as suggested, so cannot compensate for not using O2.

Wow

Here's a GIANT one: C3 photosynthesis using RUBISCO is inefficient, but scientists have designed and run a new and more efficient photosynthetic pathway in Arabidopsis:
