It is believed to have happened in the past and is currently happening. Explanation: The process of microevolution does not assess anything, it is merely a process of change. These adaptations tend to take place within four different patterns. Why don't libraries smell like bookstores? The correct answer is (A) Microevolution. Macroevolution includes everything else required to support the proposition that all life on earth developed from a single, or a few, original life forms that themselves originated naturally from non-living matter". It is believed to produce large-scale (“macro”) changes. Web Resources: The Guinness View of Macroevolution. Macro evolution is defined as evolution spanning species.
