Looking at the phylogenetic tree, which three statements can you make about the interconnectedness of the species A, B, C, D, and E?


1. Species A and C may have shared features from a common ancestor.

2. Species C is more related to species D than species D is related to species E.

3. Species B and C are more closely related than species C and D.

4. Species B and E may have shared features from a common ancestor.

5. Species A is more related to species B than species B is related to species C.

Answer 1

Option 1, 4 and 5

Step-by-step explanation:

In a phylogenetic tree, the species which emerge from the same node are more closely related as compared to the other parallel species originating from the same ancestors but at a different node.

Hence, species A is more closely related to species B as compared to the relation between B and C. Option 5 is correct

Both the species B and E will share some characteristics as they have evolved from the same ancestors, though they do not emerge from the same node. Thus, option 4 is also correct.

Similarly A and C have some common characteristics. Thus, option 1 is correct

Answer 2

The correct options are 1,4 and 5. By looking at phylogenetic tree we can conclude this;

1. Species A and C may have shared features from a common ancestor.

4. Species B and E may have shared features from a common ancestor.

5. Species A is more related to species B than species B is related to species C
