We don't usually think of speaking as similar to chewing, licking and sucking, but, like speaking, all of these actions involve movements of the mouth, tongue and lips in some kind of controlled way. So, perhaps this connection is not as improbable as it first sounds. It is an example of the type of observation that can lead to interesting speculations about the origins of spoken language. They remain, however, speculations, not facts. We simply don't know how language originated. We suspect that some type of spoken language developed between 100,000 and 50,000 years ago, well before written language (about 5,000 years ago). Yet, among the traces of earlier periods of life on earth, we never find any direct evidence or artifacts relating to the speech of our distant ancestors that might tell us how language was back in the early stages. Perhaps because of this absence of direct physical evidence, there has been no shortage of speculation about the origins of human speech. In this chapter, we will consider the merits of some of those speculations.

The divine source

In the biblical tradition, God created Adam and “whatsoever Adam called every living creature, that was the name thereof”. Alternatively, following a Hindu tradition, language came from Sarasvati, wife of Brahma, creator of the universe.
