How did the mitochondria evolve

WebThe evolutionary origin of eubacterial flagellae is probably an example of indirect evolution. A hypothesis on the evolutionary pathway of the eubacterial flagellum argues that a secretory system evolved first, based around the SMC rod- and pore-forming complex. This is presumed to be the common ancestor of the type-III secretory system and the ... WebThe eukaryotic cell seems to have evolved from a symbiotic community of prokaryotic cells.
