C
2. Which of the mystery specimens is a gracile australopith? What evidence indicates this?
B has smaller premolars and molars.
3. Which of the mystery specimens is a robust australopith? What evidence indicates this?
A has larger premolars



Answer :

Final answer:

Homo habilis had gracile features compared to australopiths, while robust australopithecines had large teeth for tough diets.


Explanation:

Homo habilis exhibited a high degree of sexual dimorphism and had more gracile characteristics compared to australopiths. Their dentition was more human-like, with smaller teeth and dental arcade. On the other hand, robust australopithecines, like Paranthropus boisei, had large premolars suited for chewing tough plant material.
