In a phylogenetic tree, the organism that has evolved most recently is found at the branch tips. This is because each branch tip represents the endpoint of a lineage’s evolution, either a currently living species or the most recently evolved form in that lineage
. To clarify:
- The base (root) of the tree represents the most ancient common ancestor of all species in the tree.
- The nodes are points where a single lineage splits into two, representing common ancestors, not the most recent species.
- The branches represent evolutionary pathways.
- The branch tips are the ends of these branches and correspond to the most recently evolved species or taxa.
Thus, the most recently evolved organism is located at the tips of the branches in the phylogenetic tree
