and likewise the close alliance of some of the inhabitants of the sea in the northern and southern temperate zones,
though separated by the whole intertropical ocean. Although two areas
may present the same
physical conditions of life,
we need feel no surprise at their inhabitants being widely different, if they have been for a long period completely separated
from each other; for as the relation of organism to organism is the most important of all relations, and as the two areas
will have received colonists from some third source or from each other,
at various periods and in different proportions, the
course of modification in the two areas will inevitably be
different. |

On this view of migration, with subsequent modification, we can
see why oceanic islands should be
inhabited by few
species, but of these, that
many should be peculiar. We can
clearly see why those
animals which cannot cross wide spaces of ocean,
as frogs and terrestrial mammals, should
not inhabit oceanic islands; and why, on the other hand, new and peculiar species of bats, which
can traverse the ocean,
are often are often 1872 |
should so often be 1859 1860 1861 |
are so often 1866 1869 |
found on islands far distant from any continent. Such facts
as the presence of peculiar species of bats,
on oceanic islands and on oceanic islands and 1872 |
and 1859 1860 1861 1866 |
on oceanic islands, and 1869 |
the absence of all other mammals, on oceanic islands, are
utterly inexplicable on the theory of independent acts of creation. |
