advantages and disadvantages of cladistics

Because a cladogram maps out evolutionary history, it has an implicit time scale. Characteristics of studies in cladistics are: There are various methodologies used by researchers to examine species in terms of their physical characteristics and trait-based theorized relationships.

Systematics, Taxonomy, and Classification. The method suffers a logical weakness, or circularity, leading to bias when characters with multiple states are used. Then the analysis or estimation is committed for the next percentage. This process can occur repeatedly with some highly successful species leading to a large group of organisms that share a common ancestor.
