Verified step by step guidance1
Examine the structure of the phylogenetic tree provided. A phylogenetic tree represents evolutionary relationships among species, where branches indicate common ancestors.
Identify the branching points (nodes) in the tree. These nodes represent common ancestors shared by the species connected to them.
Compare the positions of Species A, B, and C on the tree. Look for the most recent common ancestor shared by each pair of species.
Notice that Species A and Species B share a node closer to the present than the node connecting them to Species C. This indicates that A and B are more closely related.
Conclude that the two species most closely related are Species A and Species B, based on their shared recent common ancestor.
