WebScore: 4.3/5 (27 votes) . The key difference between cladogram and phylogenetic tree is that cladogram shows only the relationship between different organisms with respective to a common ancestor while phylogenetic tree shows the relationship between different organisms with respect to the evolutionary time and the amount of change with time. WebMost phylogenies therefore are hypotheses and are based on indirect evidence. Different phylogenies often emerge using the same evidence. Nevertheless, there is universal agreement that the tree of life is the result …
