Biologists must constantly keep in mind that what they see was not designed,but rather evolved。(你少打了一个空格)译：生物学家们必须时刻牢记他们所看到的并不是设计出来的,而是进化出来的。－－弗朗西斯 克里克 附：keep in mind 记住,牢记例句:That's something we have always to keep in mind。那是我们应该经常记在心里的。Keep in mind that you have to be home by 11 o'clock。记住,你必须在十一点以前回家。It is not easy to keep in mind what you have told me。记住你告诉我的话并不容易。
