Which is not evidence for the endosymbiotic origins of mitochondria and chloroplasts?
Zolol [24]

Mitochondria and chloroplast have similar DNA, which is not evidence for the endosymbiotic origins of mitochondria and chloroplasts.

According to the endosymbiotic theory, a chloroplast and a mitochondria were the independent prokaryotes. Both can be ingested by a large prokaryote and resist digestion. As a result, they continued as endosymbionts and eventually lost some of their autonomic properties. They divide by binary fission, have their own genetic material, possess 70s ribosomes, and Both include their own transcriptional and translational machinery.

Therefore, considering endosymbiotic origin theory, Both Mitochondria and chloroplast have similar DNA is not a piece of evidence.
