Abstract

Evolutionary processes have two underlying mechanisms: variation (expanding options) and selection (narrowing options). Darwin and Darwinism focused on the selectional mechanism, i.e., natural selection. If an evolutionary process is seen as pushing towards higher altitudes on a multi-peaked and cloudy “fitness landscape,” then selection is a hill-climbing mechanism while a mechanism for variation would explore to find higher hills. Selection without variation might get stuck on a low hill. Our thesis is that the best solution for the problem of variation is parallel experimentation with the different probes having some semi-isolation from selectional pressure and where results in the experiments can be cross-communicated and compared to ratchet up the performance of the whole group. Our approach is by seeking out the common elements addressing the problem of variation in evolutionary theory (Sewall Wright’s shifting balance theory), in various search procedures, in the selection of economic projects, and in science and technology development. The opposite strategy is series experimentation which assumes that one is already climbing the highest peak so consideration of other peaks is irrelevant. The main critical applications are to global institutions such as the World Bank or IMF who do not condone parallel experimentation since they already “know” what is the highest peak—and, more generally, to those in power on top of a low hill who know that any real variation would be downhill for them.
