An anatomical trait that changes during development from small to large. Feedback: Great job. Question 18 of 33 3.0 Points A classic scientific study showed that crayfish on one side of the isthmus of Panama were more closely related to other species on the other side of the isthmus than to each other. The most likely explanation for this result is: • A. mutation • B. gene flow • C. vicariance • D. dispersal Feedback: The most likely explanation is that a several separation crayfish species were separated by the formation of the isthmus and the then separated populations diverged.
