Two scientists produce two different cladograms for the same group of organisms. Explain how the differences are possible.

Due to different grouping style

Explanation:

A)When the organisms are grouped together on the basis of similarities shared by them – Such species are named based on the name of older species and the newly discovered species sharing similar traits are kept under older species thereby dropping its own name.  

B)In the second method, the minute differences are observed in species to group them into several branches arising from one parent organism.
