Monophyletic: A group containing all the organisms that have descended from a single ancestral species. It ensures that every member is related and includes the common ancestor.
Polyphyletic: A grouping of organisms that do not share a recent common ancestor. This category is characterized by members derived from multiple ancestral lines, leading to a composition of unrelated species.
Paraphyletic: A taxonomic group that includes the most recent common ancestor but excludes some of its descendants. This results in an incomplete representation of a lineage.
