Use the following information for the next two questions. Dr. Samwise is studying a species of ground pheasants that live around an extremely large ravine to determine if parapatric speciation has occurred. The pheasant species, Lophura diardi, is divided into seven subspecies based on morphology and the location of each subspecies around the ravine is plotted on the figure. Based on morphological observations, Dr. Samwise hypothesizes that an ancestral population similar to the Scathii subspecies originated on the eastern side of the ravine. Then, groups moved along the northern and southern sides of the ravine until the northern, and southern groups met again on the western side of the ravine. Dr. Samwise constructs a phylogeny of the subspecies using DNA data. Which of the phylogenies below support Dr. Samwise’s hypothesis based on morphological data?
