Comparisons of cranial capacity between a. africanus and the later species h. erectus and a. boisei show that h. erectus had much larger brains, while a. boisei had only slightly larger brains, than a. africanus. there is evidence that a. africanus and h. erectus used tools, though the tools made by h. erectus required more skill and planning to craft. how do you think the toolmaking abilities of a. boisei would have compared?   (a)a. boisei  would have had very little ability to make tools, unlike the other two hominids.(b) a. boisei  would have been able to make more advanced tools than the other two hominids.  (c)a. boisei  would have been able to make tools that were less advanced than  h. erectus.  (d)a. boisei  would have made tools that were less advanced than those made by  a. africanus.
