Based on the cladogram above, which conclusion is NOT justified? Sharks and ray-finned fish are about as related to each other as primates are to rodents and rabbits. The traits that are marked with red lines on the tree represent characters that are shared by all groups above that point on the tree. This tree does not contain any evidence of traits evolving independently more than once. The primates and rodents & rabbits form a smaller group that fits inside of a larger group including all animals with amniotic eggs..
