Venn DiagramThe Venn diagram above displays the common relationship each animal has anatomically. Since the Earthworm (Lubricus terrestris) does not have any skeletal structures, the Earthworm is left out of the group. The Frog (Rana pipiens), European Rabbit (Oryctolagus cuniculus), and Human (Homo sapien) have similar skeletal structures in common. Finally, the European Rabbit and Human have a specific similarity in skeletal structure that the Frog and Earthworm do not have. Below is the Cladogram, the Cladogram will show the specific differences of each animal. CladogramThe Cladogram above also follows a similar layout to the simplistic Venn diagram. However, the Cladogram explains the specific differences for each animal as it leads up to the modern specimen. The Earthworm (Lumbricus terrestris) does not have any skeletal system, however, the setaes act somewhat as a skeletal system. The setaes of the worms gives it shape and has calcium. The Frog (Rana pipiens) have a spine which the European Rabbit (Oryctolagus cuniculus) and Humans (Homo Sapiens). However, the Frog does not have a rib cage in which the European rabbit and Human have. Finally, Humans have the ability to stand upright; which the Earthworm, Frog, and European Rabbit, do not have the ability.
