Serial endosymbiosis is margulis' hypothesis that all organelles were created by a series of endosymbiosis events few believe that this is true only mitochondria and chloroplasts are believed to be created in this way, because there is no direct.

Evidence of endosymbiosis the endosymbiosis evidence holds immense importance in the endosymbiotic theory of the origin of eukaryotic cells there have been multiple endosymbiosis evidences to support the endosymbiotic theory, but very few are considered and accepted by the widely known scientists and researchers. The evidence that supports the endosymbiotic theory includes: 1 mitochondria have a circular genome 2 mitochondria divide separately from the division of the cell itself and do so in a manner similar to binary fission. Although endosymbiosis includes a huge range of interaction types, the term is commonly used in reference to beneficial, intracellular associations such mutualisms are often closely knit, evolutionarily stable, and characterized by a high degree of functional and genetic integration.
