Five species (V, W, X, Y, Z) are being compared based on the presence or absence of five derived traits. The following observations were made: Species Y lacks all derived traits and serves as a baseline for comparison. Species V and W share three derived traits, making them very similar. Species Z shares some traits with both species V and W but has fewer traits overall. Species X has two unique traits that distinguish it from the others. Which of the following statements best describes the evolutionary relationships among these species?
