The Macroevolutionary Process

Evolution is believed to proceed along two distinct scales. At the smaller scale, evolution is believed to represent changes in largely reversible, continuous phenotype that happen quickly (i.e. on the same timescale as generational turnover). This is known as microevolution. Macroevolution, on the other hand, is believed to represent permanent and discrete changes in phenotype that happen over multiple generations. I am interested in determining the simulating what the differences between these two modes of evolution may be, deriving explanations for various aspects of macroevolution such as diversification and Cope’s rule, and whether the division between macroevolution and microevolution is real.
