To quickly assess the difficulty of the text, read a short excerpt:
Those who believe that such peculiar structures can only have arisen by very minute successive variations, each one advan- tageous to its possessor, must see, in the posses- sion of such an organ by one group and its com- plete absence in every other, a proof of a very ancient origin and of very long-continued modifi- cation. And such a positive structural addition to the organization of the family, subserving an important function, seems to me alone sufficient to warrant us in considering the ...Papilionidae as the most highly developed portion of the whole order, and thus in retaining it in the position which the size, strength, beauty, and general structure of the perfect insects have been gener- ally thought to deserve. " (Nat. Select. , p. 135. ) It is unphilosophical, however, to accord high rank to any group for a single characteristic, and especially when in nearly all its other important peculiarities it evinces its low origin. Moreover, extensile fleshy scent organs do occur in other groups.
