Four different phylogenetic trees of a group of salamanders have been proposed. Trees A and B each require 12 homoplasies, but tree A requires 14 synapomorphies and tree B requires 13 synapomorphies. Tree C requires 15 homoplasies and 13 synapomorphies. Finally, tree D requires 10 homoplasies and 15 synapomorphies. According to the principle of parsimony, which tree (s) is/are the most accurate? A) Tree A only B) Tree B only C) Tree C only D) Tree D only E) Both tree A and tree B
