Three species of mouse that are similar in appearance occupy the same geographic area. One species has tan fur, one has brown fur, and the third has gray fur. Scientists studying these mice assumed that the mice with brown and tan fur would be more closely related, but they discover the tan mice and the gray mice have fewer differences in their genomes than the tan mice and brown mice. Based on this information, which of the following is the most logical conclusion?

OpenStudy (anonymous):

Gray and tan mice share a common evolutionary ancestor that is most likely not related to the brown mice’s ancestors. Tan and brown mice evolved from the gray mouse, most likely because the fur color provided a survival benefit. The gray mice does not share a common ancestor with the brown mice. The tan mice and gray mice share a more recent common evolutionary ancestor than the tan mice and brown mice.
