I have included a rather romantic video that is widely circulated on the Internet. It was a film made by a Canadian team to explain how the reintroduction of wolves in Yellowstone Park has dramatically changed the flora, fauna and geography of the park in a very short period of time. I don't know whether the film segment is accurate. It is possible that the introduction of wolves has had some other dramatic but harmful effects that the film overlooks.
In any case the film does depict the interaction of many multiple biological forces that result in unexpected outcomes.
This is because of Darwinian forces that allow species to become dominant based on local niche environments for which they have survival superiority. It is the same mechanism that allows new species to develop and evolve in the standard Darwinian model.
What I want to point out is that commerce is Darwinian. There is a constant random fluctuation as new people introduce new services and goods into a local niche market. There is a constant repression and selection that goes on in which consumers and buyers select the most desirable or suitable goods and services for each niche.
The consequence is that commerce produces incredible novelty and unexpected and often unimaginable outcomes.
