Eukaryotes have lots of ribosomes, so I'm confused about why it would be easier to create eukaryotes.
And while bigger cells absorbing smaller cells happens all the time, it seems extremely, extremely rare that those events lead to reproducing life. It's probably happened 2X on earth (whatever lead to the original eukaryotes, and the absorption by that lineage of cyanobacteria).
- koeng 6y agoThere are tons of insects with novel endosymbionts. For example, Camponotus ants have some novel endosymbionts - https://pubmed.ncbi.nlm.nih.gov/8866472/ https://pubmed.ncbi.nlm.nih.gov/8866472/ . There are even synthetic endosymbionts nowadays (e coli in yeast), and there are cytoplasmic parasites like Wolbachia that you could imagine evolving into an endosymbionts. On the other hand, even if had only occurred 2x, ribosomes occurred 1x - all ribosomes are related to each other and didn’t evolve separately.
