Transcribed Image Text: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.

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.

Review the evidence below for each hypothesis, then, using that evidence, explain whether they should be classified as distinct or the same species based on each species concept. Then, using the overall evidence, decide whether to classify them as the same or different species. Genetic Information (In the Species Concepts lab, we used a "controversial" 10% cutoff. A more realistic cutoff might be 1%. Let's use a 1% cutoff for this activity.) Sequence Differences Baltimore Oriole vs Black- backed Oriole Cytochrome b 0.26% Control region 0.74% 2A.
