Years ago there was an abbott in Hingham Mass, Abbott Campbell, who had spent many years - almost three decades - as a missionary in Africa. He was a brilliant guy who had an amazing facility with languages, and had learned 6 or 7 sub-Saharan languages fluently. If there was no one else in the church, he would sometimes say prayers in different languages, to include the click language of the Khoisan people. The Khoi and San peoples are an interesting group for a host of reasons, but for now what is relevant is that they may be the only Homo sapiens who didn’t displace another group of Homo sapiens as they migrated. They were the first.
