Consider the following information. chimpanzees have a tibia (shin bone), whose upper end is "t" shaped, as it does not have to support their entire body weight. the "t" shaped tibia is an ancestral characteristic shared by most primates. humans and members of the genus australopithecus, a fossil primate, have a "y" shape to the upper tibia, capable of supporting the full body weight, and evidence of bidpedalism. the "y" shaped tibia is a recent evolutionary adaptation, or a derived trait. additionally, australopithecus shares an ancestral small cranium with chimps and gorillas, while humans have a derived large cranium. you design a phylogenetic tree based on the information describe above. what type of approach have you employed in your classification scheme?
a) traditional approach.
b) cladistic approach.
