24. 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.
【译文】 自然选择在进化中的作用仅在一百多年前才得以阐明，而环境在塑造和保持个体行为时的选择作用则刚刚开始被认识和研究。
The role of natural selection in evolution 能否翻译成:在进化中的自然选择的作用? 我觉得介词短语in evolution 是作定语吧?那应该这样翻译呀~
请教下大家~谢谢~
