The tree below is the one that you are looking at (or should be!) for this exercise. Your classmate says that if you rotate around the node that joins Peaks

1 and 4, the flowers on Peak1 will have blue spurs. What would you say about this? "If you do this, then both Peak 1 and Peak 4 columbines will have blue spurs" "Rotating nodes does not change the evolution of the traits on the tree" If I rotated around the node that joins Peaks 1, 3 and 4 There is no way this can change
