This provided the first substantial evidence for the endosymbiosis hypothesis. It was also determined that mitochondria and chloroplasts divide independently of the cell they live in.
Explanation:
<em>What role did endosymbiosis play in the evolution of eukaryotes? Endosymbiosis led to the evolution of eukaryotic cells with mitochondria and chloroplasts. This kind of natural selection led to the evolution of eukaryotic cells and the plants and animals we see today.</em>
