Continue this process until the table is complete. While you can easily make a cladogram on your own, you couldn't make a phylogenetic tree without access to DNA or other molecular data for the animals you're studying. A cladogram resembles a tree, with branches off a main trunk. In this case, it is ok if your cladogram does not match the accepted cladogram. Based on this data, whales and hippos are This process is called convergent evolution, where analogous On the CLADOGRAM tab, use your table to create an insect cladogram. Notice that the molecular data used here are. Every cladogram has a root that serves as its origin. Select the organism in the second row.
