| Again, with respect to the singular fact of so
many terrestrial and fresh-water animals not
undergoing
any metamorphosis, whilst the
marine members of the same classes
pass through various transformations, Fritz Müller
has suggested that if
an animal during a long succession of generations had to change its habits from living
in the sea
to living on the land or in fresh-water, it
would be a
great
advantage to its descendants during their modification if they were to lose their metamorphoses;
for it is not probable that places well adapted for both the larval and mature stages, under such new and greatly changed habits of life, could
be
found unoccupied or ill-occupied by other organisms.
