Language around 40,000 BC

The Globe

Linguist Merrit Ruhlen has gone one step further and proposed that a common language once spanned the entire world. He said of this foundation language, which he calls Proto-Global: What seems to me the most probable explanation for the linguistic data, as they are presently known, is that current linguistic diversity derives from the appearance of behaviourally modern people forty or fifty thousand years ago. While anatomically modern humans may have appeared in Africa before 100,000 BC these people did not behave like us. That in itself may indicate their more rudimentary linguistic skills. Several scholars have in fact suggested that the 'sapiens explosion' as it is sometimes called, involved the development of fully modern human language as recently as 40,000 years ago.
