It is instead diversity. When you look out the window, what you see is not a predictable distribution of a particular element but an assortment of living things, and assortment which is different in each direction you look. Moreover, if you happen to see six pine trees, you don't see one paradigmatic pine tree replicated six times. You see six pine trees, each different from the others. They are all made up of elements which differ from one another.
Diversity is as fundamental to life as is order.
It is neither incidental nor detrimental. It is instead essential to the success of any biological entity. Not only do cells differ in kind, but in many cases, there are important differences among individual cells of a given kind. Similarly, the earth can exist as a biosphere precisely because of the diversity of organisms it contains. Animals are not capable of photosynthesis and would not survive if there weren't plants to trap the energy of sunlight.
