Which of the following statements is FALSE based on the simplified phylogenetic tree shown?
A
The cucumber is equally related to the apple and the pear.
B
The cucumber and the California poppy share a common ancestor at node E.
C
The most recent common ancestor between the apple and the orange is also the most recent common ancestor of the apple and the California poppy.
D
The pear and the cucumber are more closely related than the pear and the orange.
Verified step by step guidance1
Examine the phylogenetic tree to understand the relationships between the species. Each node represents a common ancestor.
Identify the node where the cucumber, apple, and pear diverge. The cucumber diverges at node B, while the apple and pear share a more recent common ancestor at node A.
Determine the common ancestor for the cucumber and the California poppy. They share a common ancestor at node E.
Analyze the relationship between the apple, orange, and California poppy. The apple and orange share a common ancestor at node D, while the apple and California poppy share a common ancestor at node E.
Compare the relationships of the pear with the cucumber and the orange. The pear shares a common ancestor with the cucumber at node D, and with the orange at node E, indicating the pear and cucumber are more closely related.
