Question

Quizplus · Accepted Answer

In a phylogenetic tree where branch lengths represent genetic changes, the organism with the longest branch has undergone the most genetic changes. Without seeing Figure 20.3, based on the question's information, if Drosophila is the correct answer, it implies that Drosophila's branch is the longest, indicating it has undergone the most genetic changes since divergence from the common ancestor.
