it has, also, been variable in the individuals of some of the species. And this fact shows that a character, which is generally of generic value, when it sinks in value and becomes only of specific value, often becomes variable, though its
phy- siological

importance may remain the same. Something of the same kind applies to monstrosities: at least Is. Geoffroy St. Hilaire
apparently
seems to

entertain
no doubt, that the more an organ normally differs in the different species of the same group, the more subject it is to
individual

anomalies.
On the ordinary view of each species having been independently created, why should that part of the structure, which differs from the same part in other independently-created species of the same genus, be more variable than those parts which are closely alike in the several species? I do not see that any
explana- tion
explanation
can be given. But on the view
that
of
species

only strongly marked and fixed varieties, we might

expect to find them still often continuing to vary in those parts of their structure which
