theory
these several relations throughout time and space are intelligible; for whether we look to the forms
of life which have changed during successive ages
within the same quarter of the world,
or to those which have changed after having migrated into distant quarters, in both cases the
forms within each class have been
connected by the same bond of ordinary generation; and the more nearly any two forms are related in blood, the nearer they will generally stand to each other in time and space;
in both cases the laws of variation have been the same, and modifications have been accumulated by the same power
of natural selection.
