If we turn to nature to test the truth of these remarks, and look at any small isolated area, such as an oceanic island
, although the total number of the species inhabiting it, will be found to be small, as we shall see in our chapter on geographical distribution; yet of these species a very large proportion are endemic,--that is, have been produced there, and nowhere else.
The volcanic nature of these oceanic islands
is evidently an extension of that law, and the effect of those same causes, whether chemical or mechanical, from which it results that a vast majority of the volcanoes now in action stand either near sea-coasts or as islands in the midst of the sea.
Only on Aldabra, which has the oldest palaeontological record of any oceanic island
within the Indian Ocean region, is fossil evidence available that demonstrates the effects of changing sea levels on extinction and re-colonisation events.

(2008) offer an innovative model based on the life cycle of a typical oceanic island
, which forms over a volcanic hotspot and then gradually sinks as its tectonic plate moves off this bulge in the Earth's crust.
Sipadan is the only oceanic island
in Malaysia; it is not attached to the continental shelf and stands on a limestone and coral stalk, rising 600 metres from the bed of the Celebes Sea.
