What term refers to a classification based on only one or a few characteristics?

Natural classification
Artificial classification
Taxonomy
Phylogeny

The correct answer is: Artificial classification

The correct term that refers to a classification based on only one or a few characteristics is indeed artificial classification. This type of classification often organizes organisms according to easily observable traits rather than their evolutionary relationships or genetic similarities, which can lead to a more simplistic and sometimes misleading understanding of biodiversity. Natural classification, on the other hand, groups organisms based on their evolutionary relationships and shared genetic features, rather than just a single aspect. Taxonomy is the overarching science of naming and classifying organisms, which includes various methods beyond just a few characteristics. Phylogeny specifically deals with the evolutionary history and relationships among species, focusing on a broader range of traits and genetic information.
