Why, again, do whole groups of allied species appear, though certainly they
often falsely
appear,
to have come in suddenly on the several
geological stages?

existed. The

the pouter and fantail pigeons. We should not be able to recognise a species as the parent of any one or more
species
if we were to examine them
ever
so closely, unless we likewise
possessed many
of the intermediate links
between their past or parent and present states; and these many links we could hardly ever
expect to discover, owing to the imperfection of the geological record. If two or three, or even more linking forms were discovered, they would simply be ranked as
so many new species, more especially if found in different geological sub-stages, let their differences be ever so
