👉 Plesiomorphs are terms that have been used to describe a type of animal or species, which is not recognized by any other living organism. Plesiomorphs can be considered as "pseudonyms" or "alias names" for existing species. For example, the plesiomorphic name for the giraffe is "Giraffa camelopardalis", which is a synonym of the actual giraffe species, Giraffa camelopardalis.
