Question: The chloroplast genome of most photosynthetic eukaryotes is roughly 5% the size of the genome of the cyanobacterium from which it is thought to have been derived. In comparison, the genome of a photosynthetic amoeba chloroplast from P.chromatophora is roughly 30%-50% the size of the cyanobacterium from which it is thought to have been derived.

Does this information suggest that P.chromatophora and other photosynthetic eukaryotes share the same history in terms of evolutionary progress? Why or why not?
