The molecular data are not found here but rabbits and whales are linked with the dogs and pigs in a cladogram due to evolutionary relationships.
<h3>What is a cladogram?</h3>
A cladogram is a graphical representation used to evidence the relationships between organisms due to a common evolutionary origin.
A cladogram is composed of a root that represents the common ancestor of the group and nodes where taxonomic groups diverge.
Cladograms based on molecular data use the homology level of nucleotide sequences of the genome to determine evolutionary relationships among individuals of different species.
In conclusion, rabbits and whales are linked with dogs and pigs in a cladogram due to evolutionary relationships.
