The things in Xiang Shan's eyes became different.
After downloading the information from DNA, the polypeptide long chain becomes a rope with designated characteristics. Each segment of this long chain, due to its own charge, either attracts or repels other parts. This unstable structure cannot be maintained for long. The fundamental laws of the universe demand that it fall to the most stable and lowest energy state.
Someone like Xiang Shan might use the analogy of "headphone wires getting tangled."
But this is actually an inappropriate analogy. The primary function for which headphone wires are designed is not "to become tangled."
The polypeptide chain carrying information, however, exists to fold into proteins. It has a spontaneous purposiveness.
The originally unconscious nature, within an almost infinite probability and spontaneous selection, produces a landscape that is almost "purposeful."
