On the ordinary view of each species having been independently created, why should
specific
or those by which the species of the same genus differ from each other, be more variable than
generic characters in which they all agree? Why, for instance, should the colour of a flower be more likely to vary in any one species of a genus, if the other

differently coloured flowers, than if all
→the species of the genus have
the same coloured flowers? If species are only well-marked varieties, of which the characters have become in a high degree permanent, we can understand this fact; for they have already varied since they branched off from a common progenitor in certain characters, by which they have come to be specifically distinct from each other;
