That is funny.. When I was in college taking an anthropology class, the professor said no way lanquages developed from a single language..
There are some who also believe that in Eternity, the Redeemed will all speak Hebrew, i.e., God’s language. FWIW
You’re right, it is funny. A course I took on the history and derivation of languages said the same thing and that most languages appeared to have derived from ancient languages in the Indus valley. They lump the african phonemes together but don’t seem to account for the variations and development of individual languages and dialects based on small tribal groups of which there are many in africa. Are they saying that the Bushmen share the same language as central or northern african tribes or that the North African groups are not distinct from the central and Southern African tribes?
The implication of that statement is almost as obvious as the finding in question.
If there was a first language among the first persons, all languages and all people result. Adam and Eve aside, first was first.
The finding here is merely evidence of the obvious
