Final answer:

On a phylogenetic tree, nodes represent common ancestors, and branches show evolutionary relationships based on traits.


Explanation:

A phylogenetic tree is a diagram that shows the evolutionary relationships among biological species based on genetic or physical traits. In a phylogenetic tree, nodes represent ancestors, and each node where the tree branches into two or more descendant branches represents a common ancestor. The length of branches can indicate the amount of molecular changes over time.
