...hondria are believed to have such an origin; see endosymbiotic hypothesis . In Acquiring Genomes: A Theory of the Origins of Species , Lynn Margulis argued that symbiogenesis was the primary force in evolution . According to her theory, acquisition and accumulation of random mutations are not sufficient ...

Prokaryotes also have cell walls , while some eukaryotes, particularly animals , do not. Both eukaryotes and prokaryotes have structur...
