Aim To provide evidence suggesting the existence of a dynamic system of extinction and replacement.
Location The Indo-West Pacific Ocean.
Methods Utilization of species distribution patterns produced by detailed systematic works.
Results The distribution patterns appear to suggest a sequence of events that is consistent with the centre of origin hypothesis. The East Indies centre is considered to operate according to the centrifugal speciation model.
Main conclusions Disjunct patterns appear to have originated in the East Indies and spread out from there. In cases where the vacated area is occupied by a sibling species, competitive (sympatric) speciation may have occurred. Over time the extinction pattern will gradually extend outward until it is played out among small populations far from their centre of origin
