英文翻译(中翻英）
为了适应不同的生态环境和leavemore offspring，昆虫在物种进化过程中，演化出了十分丰富类型用来对环境做出adjustment/adaption，（Favorable adaptions will accumulate over time.）然而值得关注和容易被忽视的是：sexualconflict也是致使male进化的原因之一。但其实原本female和male昆虫原本有完全相同的Genome，但是他们的性别致使繁殖的不同作用导致了后来完全不同的进化。根据达尔文的进化理论，是由female来选择male，因此说male是被选择的。而为了获得female的青睐并在reproductive competition中获得成功正是contribute使得会有a quite different route to speciationon male insect的四肢。根据water striders的实验，我们看到Male bugs use their hookson the antennae(like wrench) and spikes work together to grab females’ eyes 同时快速的弹跳在female身上并 mate with them而female只有正常的antennae。造成这样差距的是dll gene. By using the RNA inference，there’sno change on female, but for male water striders 很明显他们失去了他们的不同的antennae.而缺少了antennae的male water strider，结果是显而易见的，他们明显不再能够很好地控制femalewater strider 。综上所述，sexuallconflict是使得生物进化的一个原因，而生物就是在这样的竞争下发生一些改变并进化。
