The Anatolian languages thread had my little brain well addled*, and it led me to wonder what is known about the origin of African languages? Apart from this wikipedia article: http://en.wikipedia.org/wiki/Languages_of_Africa.
(A brief google brought me to this Cambridge University site, which may or may not be familiar to some of you here. It’s new to me, anyway, so I thought I’d share the love).
*addled: cognate with Middle Dutch ael, first English citation meaning liquid dung. Not sure I like that comparison, accurate though some may think it is.
