To draw: The three possible dichotomously branching phylogenetic trees showing evolutionary relationships between the three domains: Bacteria, Archaea, and Eukarya.
Introduction:
The phylogenetic tree can be constructed from DNA sequences or morphological study. The organism that shares a very similar morphology, or DNA sequences are most likely to be the descendant from a common ancestor. The closely-related organisms that are immediately descended from a common ancestor is called the sister group.
To explain: Whether the third tree is supported by genetic data.
