| For Darwin, macroevolution is just microevolution aggregated over long periods of time and space. Gould goes on to chart the fate of Darwin's ideas. |
| Similarly, microevolutionary explanations may not provide a sufficient account of macroevolution, even if such reductionism were justifiable in principle. |
| In antievolution literature, vertical change equates with macroevolution, or evolution above the species level. |
| The other is that developmental genetics offers keys to understanding macroevolution. |
| A chief difficulty in arguing for macroevolution by mutations is the fact that most expressed mutations are either lethal or semi-lethal. |
| However, in macroevolution, the traits of the entire species may be important. |
