One of the Most Surprising Aspects of the Recent Discovery

One of the most surprising aspects of the recent discovery of H.floresiensis is the

A) suggestion that this species had developed capacities for language despite their small brains, as is evidenced in their cave art.
B) evidence that this new species may have replaced Neandertals in the Middle East later than expected.
C) archaeological evidence of sophisticated astronomical knowledge.
D) suggestion that anatomically modern humans may have reached the Americas much earlier than expected.
E) evidence of sophisticated cultural abilities typically associated with anatomically modern humans, not with a hominin with a chimplike brain and extremities.
