Concepts of evolution, refugia, and succession provide a valuable lesson about modern society.
In our life times we can witness the progress of evolution in many ways, and hopefully, learn. The advance of technology illustrates these concepts. Classic examples illustrate:
• cars and displacing or replacing trains and horse-drawn carts as primary means of transportation.
• cell phones replacing telephones, which replaced telegraphs and mail services as primary means of communication.
• cable television replacing radio/TV broadcasting.
• cities grow through succession following the changes in politics, industry, and development of infrastructure.
So, should calamity happen, and an area or region should loose electrical power or access to liquid fuels, what would survive? Populations would need to migrate, adapt, or face famine. Electric- and gas-power tools and equipment would be rendered useless, but hand-powered tools like hammers, water pumps, shovels, saws and axes would be increasingly valuable!
In the business world, evolution provides particularly important concepts. It is an interesting study to see how businesses and corporations survive economic calamities caused by wars and depressions, and the rise of competing new technologies. It is a jungle out there.
