If I were a “transformist” how I should delight in this question!  Yes, I should say:  yes, by the fact of its germ every animal is originally carnivorous.  The insect in particular makes a beginning with albuminoid materials.  Many larvae adhere to the alimentation present in the egg, as do many adult insects also.  But the struggle to fill the belly, which is actually the struggle for life, demands something better than the precarious chances of the chase.  Man, at first an eager hunter of game, collected flocks and became a shepherd in order to profit by his possessions in time of dearth.  Further progress inspired him to till the earth and sow; a method which assured him of a certain living.  Evolution from the defective to the mediocre, and from the mediocre to the abundant, has led to the resources of agriculture.

The lower animals have preceded us on the way of progress.  The ancestors of the Philanthus, in the remote ages of the lacustrian tertiary formations, lived by capturing prey in both phases—­both as larvae and as adults; they hunted for their own benefit as well as for the family.  They did not confine themselves to emptying the stomach of the bee, as do their descendants to-day; they devoured the victim entire.  From beginning to end they remained carnivorous.  Later there were fortunate innovators, whose race supplanted the more conservative element, who discovered an inexhaustible source of nourishment, to be obtained without painful search or dangerous conflict:  the saccharine exudation of the flowers.  The wasteful system of living upon prey, by no means favourable to large populations, has been preserved for the feeble larvae; but the vigorous adult has abandoned it for an easier and more prosperous existence.  Thus the Philanthus of our own days was gradually developed; thus was formed the double system of nourishment practised by the various predatory insects which we know.

The bee has done still better; from the moment of leaving the egg it dispenses completely with chance-won aliments.  It has invented honey, the food of its larvae.  Renouncing the chase for ever, and becoming exclusively agricultural, this insect has acquired a degree of moral and physical prosperity that the predatory species are far from sharing.  Hence the flourishing colonies of the Anthophorae, the Osmiae, the Eucerae, the Halicti, and other makers of honey, while the hunters of prey work in isolation; hence the societies in which the bee displays its admirable talents, the supreme expression of instinct.

This is what I should say if I were a “transformist.”  All this is a chain of highly logical deductions, and it hangs together with a certain air of reality, such as we like to look for in a host of “transformist” arguments which are put forward as irrefutable.  Well, I make a present of my deductive theory to whosoever desires it, and without the least regret; I do not believe a single word of it, and I confess my profound ignorance of the origin of the twofold system of diet.
