For centuries, it was thought that male songbirds alone used song as they used fancy plumage and elaborate tails, to attract females and compete with rival males. The female role was to listen and choose and, in so doing, exert influence through sexual selection, driving the evolution of elaborate singing by preferring males with ever more melodious and complex songs. This was considered a classic example of the power of sexual selection to generate extreme sex differences in brain and behavior. Instances of female song were largely dismissed as atypical—rare exceptions or the outcome of hormonal abnormalities.
All that changed when the international team of researchers led by Karan Odom surveyed the occurrence of female song in 1,141 species from all over the world. The team suspected that male-only song was not the whole story by any stretch. Most songbird species live in tropical regions, which have been less studied. And female song is more common in Australia and surrounding areas, where songbirds originated. There, it’s a much more egalitarian setup. Sure enough, the results of the study, published in 2014, showed that female song occurs in more than two-thirds of surveyed songbird species and families—and that it’s structurally similar to male songs (long and complex) and used for similar purposes. In the songs of male and female superb starlings of eastern Africa, for instance, there’s no difference in the structure or the number of motifs that each sex sings. Both sexes in this highly social species sing all year long and may do so to signal identity and establish rank within their groups. The study made it clear: Birdsong is not just a male thing. And elaborate song did not evolve just through sexual selection—females choosing males for their vocal prowess—but through the broader process of social selection: both sexes competing for food, nest sites, territories, and mates.

我对谐音梗欲罢不能
Er beugte sich vor und streckte ihr langsam Zunge entgegen. Er ließ sie auf- und abflappen wie einen gefangenen Schmetterling
Sie kann sich so viel Zeit mit dem Abschied lassen wie die Bäume, die sich dem Jahr entziehen, jeder mit seiner eigenen Geschwindigkeit. Den Ahorn hat die Kälte schon erfasst, während in den Linden noch der Sommer steckt.

感觉不用买高价牛肉卷了上上次跟教授说我的下一步计划，一是解决基础问题，二是扩大应用面，教授回复：嗯，我也觉得下一步应该首先扩大应用面。
上次教授又问到应用面做得怎么样了，我说我现在还是想先搞基础的东西。教授说：嗯，下次开会给我们展示一下你应用面的进展。
教授是只听得见他想听到的吧
太多想干的事情了怎么办啊，我工作之外的兴趣怎么这么广泛，难以想象我竟然有一段时间对什么都不感兴趣
我突然想起来电影千星之城里面为了清路而毁掉途经的星球的灵感是不是来自银河系漫游指南？但是在千星之城里看到这个情节我的感觉是：好残忍！好过分！在银河系漫游指南里我的感觉是：好好笑！哈哈哈！
It is worth repeating at this point the theories that Ford had come up with, on his first encounter with human beings, to account for their peculiar habit of continually stating and restating the very very obvious, as it ‘It’s a nice day,“ or ”You’re very tall,“ or ”So this is it, we’re going to die.”
这个现象我也惊奇很久了
之前说到我遇见生词都不是在浏览器上，都是读书的时候。为了使用这个 Burning Vocabulary，我把 epub 转成 txt，然后在静态博客的本地 repo 里建了个文档，把内容都复制过去，然后在浏览器里预览。。
折腾死我了
但是它 40 个词以上要交钱啊好烦！我感觉我都可以写一个！（还是算了
