When we study macroevolution, we look at the overall pattern of change that caused the speciation to occur. This includes the diversity, speed, or direction of the change that caused the new species to emerge from the old one. Speciation generally happens at a very slow pace.

The term divergent evolution is believed to have been first used by J. T. Gulick. Divergent evolution is commonly defined as what occurs when two groups of the same species evolve different traits within those groups in order to accommodate for differing environmental and social pressures.
