Answer: What does the endosymbiont hypothesis propose? It proposes that early eukaryotic cells acquired the precursors of mitochondria and chloroplasts by engulfing certain types of bacteria. ... Mitochondria, chloroplasts, and centrioles in eukaryotic cells each contain their own minute and unique supply of DNA.
Explanation:
The first piece of evidence that needed to be found to support the endosymbiotic hypothesis was whether or not mitochondria and chloroplasts have their own DNA and if this DNA is similar to bacterial DNA. This was later proven to be true for DNA, RNA, ribosomes, chlorophyll (for chloroplasts), and protein synthesis.
