It all soon after the mass extinction they kill dinosaurs. As shown by the above cladogram, several cases of mammals evolve from the common memo ancestor. Each line in the diagram represents an evolutionary lineage. The cladogram describes an example of which macroevoloutinary pattern, and for what reason?
