Answer & Explanation: The initial classification of protists under the kingdom Protista was polyphyletic. This means that they had multiple ancestral sources or refers to a taxon that does not contain the most recent common ancestor of its member. As a result, it was observed that some protists are more closely related to other eukaryotes than to each other, and this brought about their reclassification into "supergroups". The entire domain is now recognized as Eukarya.
