Many factors control radiations on islands, but some general patterns do emerge. Bird radiations are mostly found on oceanic archipelagos far from the continental coast line. Mammal radiations are mostly know from island arcs, which are somewhat easier to reach though still isolated enough to allow evolutionary lineages to develop and diverge. In contrast to birds, strong mammal radiations seem possible on a single island.
