Among the host of sceptics and were they not legion? who met this evolutionary and revolutionary theory with incredulity, not to say ridicule or worse, was one who thus challenged its author shortly after the appearance of his "Fertilization of Orchids," addressing Darwin from Madagascar substantially as follows: "Upon your theory of evolution through natural selection all the various contrasting structural features of the orchids have direct reference to some insect which shall best cross-fertilize them.
He has shown us most convincingly how the several literary forms, the lyric, the oration, the epic, with its illegitimate descendant, the modern novel in prose, may cross-fertilize each other from time to time, and also how the casual hybrids that result are ever struggling to revert each to its own species.
The jay, by his propensity to carry away and hide things, plants many of our oak and chestnut trees, but who dares say that he does this on purpose, any more than that the insects cross-fertilize the flowers on purpose? Sheep do not take thought of the wool upon their backs that is to protect them from the cold of winter, nor does the fox of his fur.
Accordingly he called the tall character dominant, and the dwarf character recessive, and a pair of contrasted characters which act in this way are now called factors or sometimes called unit characters. But on allowing these hybrids to cross-fertilize one another in the usual way, Mendel found that in the second generation of hybrids there were always three talls to one dwarf out of every four.
