"African languages". Many African languages had complex linguistic structures that were on a par with Latin and Frisian, for instance. A dialect is a variation in a given language. The key elements that make up dialects are phonology, grammar and lexis (vocab). Sadly, dialects have a negative connotation. So I wouldn't group African languages under the dialect umbrella. It contradicts the points you made so well. :-)
