在这种转变中，历史学家研究历史时，解释新史料的新方法充实了传统的历史研究方法。

The role of natural selection in evolution was formulated only a little more than a hundred years ago, and the selective role of the environment in shaping and maintaining the behavior of the individual is only beginning to be recognized and studied. (2002年翻译)
