Instead, he looked for a way to practice the loves of his life - biology and geology. To respectfully accomplish this, and still have the illusion that he was working, it was arranged that he would become a country parish priest that required minimal work while allowing him plenty of time for biogeological classification and study. Of course he needed to do further study, of course he needed to write, and there were other things that as a scholar and scientist he had to do. He knew what his findings and theory would prompt. In one respect, there was nothing new about evolution which had been around for a long, long time.
Natural history is nothing but evolution - the slow evolving of the planet and life forms.
In fact, the word evolution was commonly used and understood as describing a part of science that Darwin was refuting. And there were two ideas in natural selection that Darwin knew would be dangerous, drawing the wrath of all Christians and the Church of England. First, natural selection is random - it is not planned, there is no design to evolution, in other words God did not predestine the world and life as we know it. And second, Darwin went further than anyone else had dared to go when he wrote that human beings are just part of the mix, simply part of the cosmos - we evolved just like everything else. Actually, one of the reasons why Darwin finally did publish Origin was that another Englishman was about to present a similar book, but he had not gone as far as Darwin.
