缺少are会产生歧义，可理解为" they enhance reproduction or survival, but simply random....

simply是adv一定要有修飾的動詞，一定要補are
此句要看成......,but .........的平衡（非not....but.....）

1. 没有了are simply的没有修饰的对象
simply 仅仅

1.but simply存在歧义，可能是favored所引领的形容词性修饰语的一部分，也可能指代前面的生物特性
2.此处simply修饰 random，simply random by-products 的意思就成了，简单随机选择的副产品，不合句义

缺少are的歧义：可能认为favored because they enhance reproduction or survival 和 but simply random by-products都是修饰natural selection的

选对了 are not but 的结构但是没有注意到but小分句没有动词的歧义

缺少are的歧义：可能认为favored because they enhance reproduction or survival 和 but simply random by-products都是修饰natural selection的

without the "are", can cause ambiguous meaning

but在C中可能会导致enhance reproduction, but simply random这样的歧义。加上but are才能确认与are not的平行的结构。

如果不加 are，可能产生but做介词的歧义
