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 ... WebMitochondria are proposed to have evolved from primitive prokaryotes that could utilize oxygen for respiration (aerobic prokaryotes) following their ingestion into the proto-eukaryotic cells through the process of phagocytosis (Fig. 20.8). The O 2 utilizing prokaryotic cells became symbionts of the proto-eukaryotic cells which had ingested them.
