8. Complexity comes and goes.
复杂性增加又减少。

Other than creationists, most people have no trouble appreciating the difference between "orderly" (low entropy) and "complex." Entropy increases, but complexity is ephemeral; it increases and decreases in complex ways, unsurprisingly enough. Part of the "job" of complex structures is to increase entropy, e.g. in the origin of life. But we're far from having a complete understanding of this crucial phenomenon.
除了神创论者，大多数人都能够明白“有序（低熵）”和“复杂”的区别。熵在不断增加，但复杂状态是短暂的；复杂性以复杂的方式增加和减少，这一点也不令人意外。复杂结构存在的“意义”之一就是使各种过程——比如生命起源——中的熵增加。但我们还远未能对这一至关重要的现象有全面的理解。
