Guida verificata passo dopo passo1
Examine the first tree: It shows a branching pattern where A and B are closely related, and D and E are closely related, with C being more distantly related to all.
Understand that evolutionary trees can be rotated at their nodes without changing the relationships. This means the order of the branches can be rearranged as long as the connections remain the same.
Look for a tree among the options that maintains the same grouping: A and B together, D and E together, and C as a separate branch.
Compare each tree to the original tree's structure. Check if the branching pattern and the relative positions of the groups (A-B and D-E) are preserved.
Identify the tree that has the same evolutionary relationships by ensuring the same clades (groups) are present and the branching order is consistent with the original tree.
