A cladogram is a diagram used to represent a hypothetical relationship between groups of animals, called a phylogeny.A cladogram is used by a scientist studying phylogenetic systematics to visualize the groups of organisms being compared, how they are related, and their most common ancestors. C. that originated from the same stem cells. C. by overexploitation, humans have caused many predatory species to become endangered The presence of mountain ranges tends to produce extremes in precipitation 2. Monophyletic grouping shows groups of organisms that are closely related to each other with a common ancestor. In the example cladogram, the outgroup is Species E. It is related to the root organism but it is not as closely related to the other terminal nodes or species as those terminal nodes are to each other. Five of these species are then discovered; these are shown as boxed on the left.
