Answer: “Comparing the mitochondrial DNA between different eukaryotes to see how closely they are related.”
The endosymbiotic theory focuses on the origin of two eukaryotic organelles that have bacteria characteristics (mitochondria in animals and chloroplasts in plants). These two are s are believed to have developed from symbiotic bacteria.
In designing an experiment that would support the endosymbiotic theory, the statement that would provide the best evidence is comparing mitochondrial DNA between different eukaryotes to see how closely they are related.
