Did Homo Erectus Have a (Vocal) Language?
摘要
After the human–chimpanzee split, the human-related lineage evolved into different species of Homo. However, only one of these species, or anatomically modern humans (AMHs), has survived, leading to what we are. A question of language evolution that has remained both appealing and controversial is whether AMHs were the first and only species of Homo to have a vocal language. Although there are viewpoints in favor of the emergence of such linguistic capability only in AMHs, or also in Neanderthals, this review argues for a much earlier emergence of it in Homo erectus by accumulating evidence from anatomy, genetics, archaeology, and social cooperation. The article ends with a discussion that defends the vocal hypothesis of language origin based on a critique of the gestural hypothesis.
