Even if it could be proven that species, like varieties, are formed by development, it does not follow that genera and families and classes are so developed. But it has not been proved that a single species has been added by development, much less orders, families and genera. Evolution must account for every division and sub-division to plant and animal life. Darwin answers the objection to the sterility of hybrids by saying, “We do not know.” “But why,” he says, “in the case of distinct species, the sexual elements should so generally have become more or less modified, leading to their mutual infertility, we do not know.” But God knows. 23. THE INSTINCT OF ANIMALS The instinct of animals is not due to their own intelligence. It is unerring, unchangeable, without improvement or deterioration. It implies knowledge and wisdom of the highest order. It is beyond the wisdom of man. It comes direct from God. It is not learned nor gained by experience. It is found in many species of animals, and even in a child, until knowledge and reason make it unnecessary. One of the most familiar illustrations is the instinct of the honey bee. It builds its cells in exact geometric form and we compute, by Calculus, that the form it uses produces the greatest capacity in proportion to the amount of material used. Who taught the bee to build its cell, displaying greater knowledge than that of many a college graduate? Darwin says (Origin of Species), “It can be clearly shown that the most wonderful instincts with which we are acquainted, namely those of the honey bee, could not possibly have been acquired by habit.” We quote from Granville’s Calculus, p. 119: “We know that the shape of a bee cell is hexagonal, giving a certain capacity for honey with the greatest possible economy of wax.” This is demonstrated by the solution of a problem in this same Calculus. Darwin again says (Origin of Species, vol. I, p. 342), “We hear from mathematicians, that bees have practically solved a recondite problem, and have made their cells of the proper shape to hold the greatest possible amount of honey, with the least possible consumption of precious wax in their construction. It has been remarked that a skilful workman, with fitting tools and measures, would find it very difficult to make cells of wax of the true form, though this is effected by a crowd of bees, working in a dark room. Each cell, as is well known, is a hexagonal prism, with the basal edges of its six sides, beveled so as to join an inverted pyramid of three rhombs. These rhombs have certain angles, and the three which form the pyramidal base of a single cell on one side of the comb, enter into the composition of the bases of the three adjoining cells on the opposite side.” Can any one suggest an improvement or show an imperfection? If this intelligence is the bee’s own, which is far superior to that of the ape, why did not the bee develop a human brain?
