Which of the following is not an example of evidence supporting the endosymbiotic theory?
Correct answer: D. None of these
- A. Mitochondria contain their own DNA, which is a single circular chromosome
- B. Mitochondria and other plastids multiply by binary fission
- C. Mitochondria have their own ribosomes, which are 70S
- D. None of these
Explanation
The endosymbiotic theory posits that some eukaryotic cell organelles evolved from free-living prokaryotes. All of the mentioned options show similarity between mitochondria and bacteria, indicating that mitochondria too could have been an independent bacteria initially that got ingested by an endosymbiont cell. This is the basis of and hence supports the endosymbiont theory.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
