The phylogenetic tree of animals shows that
WebbWhy is the tree of life a phylogenetic tree? Scientists consider phylogenetic trees to be a hypothesis of the evolutionary past since one cannot go back to confirm the proposed relationships. In other words, a “tree of life” can be constructed to illustrate when different organisms evolved and to show the relationships among different organisms (Figure 2). WebbMarsupials have the typical characteristics of mammals —e.g., mammary glands, three middle ear bones, and true hair. There are, however, striking differences as well as a number of anatomical features that separate …
