Background
•West Africa is one of the most complex regions of the world, linguistically speaking
•Three unrelated language phyla meet and interact there and there are also traces of language isolates, i.e. languages of prior populations
•The geographical fragmentation of these language groups suggests considerable movement and ‘layering’ in prehistory
•In principle it should be possible to correlate these with archaeology
•In practice, the density of archaeological sites is far too low to put forward more than speculations
