The diagram represents the evolutionary relationships among many organisms. Three species with the most similar traits are most likely1) F, I, G2) D, H, J3) B, D, G4) F, A, J

Solution:
A clade is a group of organisms that includes an ancestor and all of its descendants. Clades are based on cladistics. This is a method of comparing traits in related species to determine ancestor-descendant relationships. Notice that, according to this, H and J are more closely related than the other options. So that, we can conclude that the correct answer is:
2) D, H, J
