 Even in chemical soups individual molecules are arranged in a particular pattern. This pattern affects, for example, which molecule encounters another. When analyzing such soups, however, chemists do not try to decipher the arrangement but instead rely on statistical measures about the likelihood of encounters. But cells are different—different molecules are segregated in different locations and how they are organized affects the resulting behavior (this is true even in prokaryotic cells that lack internal membranes, with molecules segregated in different parts of the cell, sometimes changing location over the course of a day; see Cohen, Erb, Selimkhanov, et al., 2014). Organization is also important in manufactured products. If the parts of your computer were distributed on your desk, and each part was provided with some input so that it was performing an operation, the parts would still not carry out the same activities as they do when they are in their proper arrangement. Organization ensures that the outputs of one component are passed to the appropriate others as inputs. The importance of organization is further recognized when one considers that what human designers do is impose new organization on existing components to achieve novel desired effects. Evolution often does the same in biology.
