Answer:

Explanation:
Australopithecine refers to several species of an extinct bipedal primate. Researchers disagree on which of the species evolved into the homo in Africa two million years ago. However, observation of their remains indicates that australopithecines possessed larger post canine teeth with more enamel that modern humans and apes, which could demonstrate their consumption of hard food like nuts.
