Answer:
Cladistic analysis compares the shared and shared derived characteristics of organisms which are thought to be of same ancestral origin.
Explanation:
- The branch of sytematics concerned with inferring phylogeny is termed as cladistics.
- It determines the branching pattern of evolution.
- It decribes the sequence of branching of ancestral lines.
