Which of these statements is not a characteristic of the cladistics system?
a) it shows the "rank" of the organism.
b) it shows the probable sequence of origins.
c) it shows shared, derived characteristics.

The correct answer is option A.

Explanation:

A biological classification system, which comprises the classification of organisms on the basis of the shared traits is known as cladistics. The organisms are generally grouped on the basis of how closely they are associated, and thus, it can be used to find the ancestry back to shared common ancestors, and the origin of various features.  

Cladistics system is not used to demonstrate the rank of the organism, it generally shows the shared and derived characteristics and the probable sequence of origins.
