Natural science in England, as Darwin already knew to his cost, was still the purview of Christian scholars. But here was a question that Darwin found compelling: if God had created all the creatures of the world, what possible reason could there be for the variations found in the Galápagos?
In 1867, George Campbell, Duke of Argyll, had published The Reign of Law, a book that Darwin found deeply annoying. A supporter of Richard Owen, Campbell argued that while evolution (or "Development") might be observable in the fossil record, it was merely evidence of God's purpose. God, for example, would cause horses and oxen to evolve in time to meet human needs. The brightly colored plumage of birds, Campbell went on, were simply God's decorations of nature for humanity's enjoyment.
In what appears to have been an unplanned quip, Wilberforce asked Huxley if he thought he was descended from an ape on his father's or mother's side. Huxley retorted that he would rather have simian relatives than claim kinship with a man who used his charisma and authority to quash free debate.
Thomas Wollaston, in the Annals and Magazine of Natural History, complained that Darwin did no seem to know what a species actually was. The British Quarterly, deliberately sitting up trouble, speculated that a time might come when a monkey could propose marriage to a genteel British lady. Perhaps cruelest of all was a cartoon in Punch magazine, depicting a gorilla with a sign on its neck. Deliberately evoking the anti-slavery tract of Darwin's Wedgwood forbears, the sign read:"Am I a Man and a Brother?
