The basic structure of proteins is quite simple: they are formed by hooking together in a chain discrete subunits called amino acids.

Although Darwin was able to persuade much of the world that a modern eye could be produced gradually from a much simpler structure, he did not even attempt to explain how the simple light sensitive spot that was his starting point actually worked.
