把这一句，留给此刻的你
In Darwin's time all of biology was a black box: not only the cell, or the eye, or digestion, or immunity, but every biological structure and function because, ultimately, no one could explain how biological processes occurred.
在达尔文的时代，所有的生物学都是一个黑盒子:不仅是细胞，眼睛，消化，免疫，还有所有的生物结构和功能，因为最终没有人能解释生物过程是如何发生的。
