Where next?
qThe work
on palaeohydrography will continue to enrich
the picture of the early Sahara
q Animal genetics should improve our
understanding of zoogeography and in particular which faunal movements
are associated with the most recent green Sahara
and which with much older movements
q Linguistic
research, particularly on Nilo-Saharan needs to
develop more relevant
reconstructions
q and archaeology needs to provide us with more
dates!
