* A due to their enhancement of reproduction or survival, but that they are 分析A选项
B due to the reproduction or survival they enhance, but they are 分析B选项

not, but 的用法
1.not.. but中be动词没那么严格要求,be动词可以放在not前,but后加动词
2.but可以作为连词用也可以作为介词用,注意不同选项中but的用法
3.选项C中,but可以理解成为介词,并属于because从句中。一起修饰natural election.所以要补出are
