   台湾籍旅美老师今天交给我们的句子是:


  Look closely and you'll see parts that aren't there because you need them but because your animal ancestors did. No longer serving their previous function but not costly 1 enough to have disappeared, these remnants of our deep history only make sense within the framework of evolution by natural selection.
  你仔细看看就会发现,有些毫无用处的身体部位是因应动物祖先的需求而存在的。虽然这些部位跟以往的功能不同,但也不至于完全消失。我们深厚历史下的这些遗迹在物竞天择的进化论下有迹可循。
