Do you have a good link about LUCA genes looking like a rock-boring microbe? That still sounds vaguely consistent with earth-based abiogenesis, but interesting

Do you have a good link about LUCA genes looking like a rock-boring microbe? That still sounds vaguely consistent with earth-based abiogenesis, but interesting for sure.
- adastra22 4y agoI’m having trouble finding an article to back up my claim, so I fear I must be misremembering. Current consensus seems to be that LUCA was part of the hydrothermal vent ecosystem.
- andrewflnr 4y agoRight, I'm not a microbiologist, but it seemed like similar genes might be involved for chemoautotrophy(?) that we would expect in early earth-based life at a vent system as for rock-boring microbes that could survive a trip from Mars to Earth. I appreciate you replying, though. :)
- adastra22 4y agoThat's my understanding as well. But I'm also not an astrobiologist. Just spent a couple of years working with them.
