Question:
Which one of the following rooted tree topologies best describes the primate phylogeny?
Which one of the following rooted tree topologies best describes the primate phylogeny?
Show Hint
Phylogenetic trees are constructed based on evolutionary relationships. Close relatives share a more recent common ancestor and are grouped together on the tree.

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The primate phylogeny is best described by the tree topology that groups species based on their evolutionary relationships. The correct topology for primates should:
1. Group {Homo sapiens}, {Pan troglodytes}, and {Pan paniscus} together, reflecting their close evolutionary relationships.
2. Place {Gorilla gorilla} as the next closest relative.
3. Position {Hoolock hoolock} as the most distantly related species. Tree topology ( {III} ) satisfies these conditions by accurately reflecting the evolutionary hierarchy of the species.
