There is little evidence to prove where protists originated from, but biologists are currently testing DNA and RNA to find an answer. However, biologists do agree on the ancestry of one group of protists. What do biologists say originated from ancient green algae? This has been discovered by comparing the RNA sequences of modern plants and green algae.
