The mitochondria of eukaryotes share similarities with living alpha-proteobacteria, an ancient clade of aerobic bacteria. List two lines of evidence supporting the idea that mitochondria evolved from an alpha- proteobacterium symbiont that inhabited a larger host cell. a. b. Explain why these similarities between mitochondria and alpha-proteobactera are not interpreted as evidence that the domain Eukarva evolved directly from an alpha- proteobacterial ancestor.
