Part B- Phylogenetic trees and geographic relationships The island fox, Urocyon littoralis, is endemic to the Channel Islands, which are located off the coast of southern California, Six of the eight Channel Islands support fox populations, and each of these islands is home to a distinct subspecies, as shown in the table below. Island Subspecies Santa Cruz santacruzae Northern Chanel Islands Santa Rosa U. I. santarosae San Miguel U. I. littoralis San Nicolas U.I. dickeyi Southern Channel Islands San Clemente U.I. clementae Santa Catalina U.I. catalinae The island fox shares a common ancestor with the gray fox. Urocyon cinerecargenteus, which is found on the mainland. Both species have similar coloration and a diploid chromosome number of 66. One structural difference between the two species is the reduced size of the island fox, a feature known as dwarfism. The various island subspecies also differ from each other in size, number of tail vertebrae, and other characteristics The phylogenetic tree below shows the evolutionary relationships between the island fox subspecies and the gray fox Drag the labels to their appropriate locations on the tree. First, drag the labels of Group 1 to identify the common ancestors at the branch points. • Next, drag one label of Group 2 to identify the homologous characteristic. • Then, drag one label of Group 3 to identify the relationship between the two species.
