The endosymbiotic hypothesis of mitochondrial origins suggests that modern-day mitochondria are descended from symbiotic bacteria, in particular an ancestral member of the purple nonsulfur photosynthetic bacterial group. How can evolutionary biologists be so specific as to group of origin? What kinds of analyses would help narrow down the possibilities, leading biologists to this group?
