    We summarize data showing that there is population structure in African populations of Drosophila from the melanogaster-simulans complex. In D. melanogaster, population structuring is found at individual loci, but is obscured by population structuring for large inversions that simultaneously affect several loci. In D. simulans, molecular polymorphism at the X-linked vermilion locus suggests that different groups of populations have been geographically isolated for some time. Invading populations are probably derived from different areas in Africa. European populations originate from an east African population that was probably not at a demographic equilibrium. The origin of the Antilles population is apparently different and is as yet unknown. In south-western France, populations from these two species undergo different population structuring at the scale of a few kilometres: D. melanogaster makes up a large panmictic population, whereas D. simulans forms a metapopulation that is divided into smaller demes.
