451 페이지 - It was evident that such facts as these, as well as many others, could only be explained on the supposition that species gradually become modified ; and the subject haunted me. But it was equally evident that neither the action of the surrounding conditions, nor the will of the organisms (especially in the case of plants) could account for the innumerable cases in which organisms of every kind are beautifully adapted to their habits of life — for instance, a woodpecker or a tree-frog to climb trees,...
