Based on hand anatomy, robust australopithecines may have __________.

B) been among the earliest makers of stone tools
C) been limited to using natural objects as tools
D) been clumsier tool makers than contemporary gracile australopithecines

Question

Quizplus · Accepted Answer

The robust australopithecine hand anatomy suggests they had greater strength and dexterity, which would have aided in the creation and use of stone tools. This makes choice B the best fit. Choices A and C are both incorrect because they suggest that the robust australopithecines did not use tools or were limited to using natural objects, which is not supported by their anatomical features. Choice D is incorrect because there is no evidence that robust australopithecines were clumsier tool makers than gracile australopithecines.
