May 16,  · Evolution Essay Evolution is the theory that all living forms came from ancient ancestors. Through a series of mutations, genetic drift, migration, and natural selection today’s descendants show an amazing amount of similarities and diversity. This essay considers three kinds of evolution that have had theoretical significance in university pursuits: Linguistic evolution (which forms an intellectual background for other models of evolution), biological evolution (where the idea has been most interesting), and cultural evolution (where the idea has never worked very well).
