Madagascar has a striking and peculiar fauna. It has been proposed that the ancestors of Madagascar's present-day mammal stock rafted there from Africa, but the validity of this hypothesis is questioned. Using palaeogeographic reconstructions and palaeo-oceanographic modelling, surface currents during the Palaeogene period are now shown to have been capable of transporting the animals to the island, as required by the hypothesis.
