Final answer:
To determine the phylogenetic history of a field mouse, you would need to find the branch in the phylogenetic tree where the field mouse is located and trace its ancestry back to the common ancestor.
Step-by-step explanation:
A phylogenetic tree is a way of showing how different organisms are thought to be related to one another from an evolutionary standpoint. To determine the phylogenetic history of a field mouse, you would need to find the branch in the phylogenetic tree where the field mouse is located and trace its ancestry back to the common ancestor. From there, you can identify the three organisms in the correct order that show the phylogenetic history of the field mouse.
