So far, so good. What is more than a bit odd, however, is that some of the most ardent opponents of Darwinian evolution -- for example, many fundamentalist Christians -- are among the most ardent supporters of the free market. These people accept the natural complexity of the market without qualm, yet they insist that the natural complexity of biological phenomena requires a designer.
They would reject the idea that there is or should be central planning in the economy. They would rightly point out that simple economic exchanges that are beneficial to people become entrenched and then gradually modified as they become part of larger systems of exchange, while those that are not beneficial die out. They accept that Adam Smith's invisible hand brings about the spontaneous order of the modern economy. Yet, as noted, some of these same people refuse to believe that natural selection and "blind processes" can lead to similar biological order arising spontaneously.
These ideas are not new. As mentioned, Smith, Hayek, Popper, and others have made them more or less explicitly. Recently, there have appeared several more mathematical echoes of these analogies invoking network, complexity, and systems theory. These include an essay by Kelley L. Ross as well as briefer comments by Mark Kleiman and Jim Lindgren.
There are, of course, quite significant differences and disanalogies between biological systems and economic ones (one being that biology is a much more substantive science than economics), but these shouldn't blind us to their similarities nor mask the obvious analogies.
These analogies prompt two final questions.
What would you think of someone who studied economic entities and their interactions in a modern free market economy and insisted that they were, despite a perfectly reasonable and empirically supported account of their development, the consequence of some all-powerful, detail-obsessed economic law-giver? You might deem such a person a conspiracy theorist.
