For each statement about the trees shown below, indicate whether it is TRUE (1) or FALSE (2). These trees show that there are far more species of tetrapods (vertebrates with four limbs) than there are of bony fishes. Only tree 1 is accurate because it shows humans, the most complex species, at one end and fishes, the simplest lineage, at the other end. Humans and lizards are equally closely related to frogs according to both trees. The only difference between these two trees is that some of the internal nodes have been rotated. They show the same topology and therefore represent the same evolutionary relationships. The lineage represented by fishes has been evolving for a much longer time than the lineage represented by lizards.
