Web4. Each branch tip on a phylogenetic tree represents a specific group of organisms known as a (n): 1. branch point or node. 2. Sister taxa. 3. evolutionary lineage. 4. taxon. The branching pattern of a phylogenetic tree indicates whether taxa are closely or distantly related relative to other taxa in the tree. WebThe tree like structures tries to reconstruct the history of life by grouping the organisms according to their relationship with their ancestor.
