Image constructed for use with cladogram. This Image illustrates the six possible solutions to the problem raised in T56.061225. The red, blue and yellow fields link equivalent solutions (in each pair the images are structurally the same and therefore redundant). What is significant is the form which occupies the most basal node (those circled in red). This place denotes the most common form. Threfore, either of the cladograms outlined in blue would be the correct solution.
