Traditionally morphological features are used to construct phylogenic trees of related species. In recent years, molecular sequences of nucleic acids or proteins, called the "molecular clock” by some researchers, have been used to reveal phylogenic relations. This diagram shows phylogenic trees of selected groups of mammals. The tree A is based on morphological features, whilst the tree B is based on molecular data. What statement about the differences of the two phylogenic trees is accurate? A. The common ancestors of Carnivora/Rodentia and Chiroptera/Primates are the same for tree A; they are different for tree B. B. The common ancestors of Carnivora/Rodentia and Chiroptera/Primates are the same for tree A; they are the same for tree B. C. The common ancestors of Carnivora/Rodentia and Chiroptera/Primates are different for tree A; they are different for tree B. D. The common ancestors of Carnivora/Rodentia and Chiroptera/Primates are different for tree A; they are the same for tree B.
