Why do you think we go on roller coasters, watch horror movies or in my case, fly through the air?

你认为我们为什么会坐过山车、看恐怖电影， 或者就我而言， 会在空中飞翔？

In this case, flying insects would have evolved before Delitzschala, but not as early as Rhyniognatha -- and we just don't know when, thanks to the gap.

在这种情况下， 飞虫会在 Delitzschala 之前进化，但不会像 Rhyniognatha 那样早——而且我们只是不知道什么时候，这要归功于差距。
