| A chief difficulty in arguing for macroevolution by mutations is the fact that most expressed mutations are either lethal or semi-lethal. |
|
| Creationists are usually more careful about distinguishing between microevolution and macroevolution at this point. |
|
| In antievolution literature, vertical change equates with macroevolution, or evolution above the species level. |
|
| Similarly, microevolutionary explanations may not provide a sufficient account of macroevolution, even if such reductionism were justifiable in principle. |
|
| The next generation of advances in macroevolution and evolutionary paleoecology will not occur until a well-tested phylogenetic classification is established. |
|
| While it may apply to populations, it is unlikely to apply to species or supraspecific taxa, and macroevolution in general. |
|
| The creation science folks accept microevolution but not macroevolution. |
|
| Creationists argued that while Gould's proposed mechanism could explain speciation, it could not explain macroevolution. |
|
| Instead, they say that macroevolution is nothing more than microevolution played out over long periods. |
|
| The other is that developmental genetics offers keys to understanding macroevolution. |
|
| However, in macroevolution, the traits of the entire species may be important. |
|
| 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. |
|
| Some who study smaller-scale evolution within species, called microevolutionists, reject Dr. Gould's arguments that there are unique features to large-scale evolution, or macroevolution. |
|
| Many credit punctuated equilibrium with promoting the flowering of the field of macroevolution, in which researchers study large-scale evolutionary changes, often in a geological time frame. |
|
| This runs contrary to evolutionary biology's account of universal common ancestry and its phylogenetic tree, that is, that all life on the planet is related via macroevolution. |
|
| These outcomes of evolution are distinguished based on time scale as macroevolution versus microevolution. |
|
| In general, macroevolution is regarded as the outcome of long periods of microevolution. |
|
| David Sepkoski's admirable essay on macroevolution addresses both familiar and not so familiar issues. |
|
| This activity offers one way to teach students about macroevolution by demonstrating that variation in the development of individuals is fodder for large changes in shape. |
|
| Family level phylogenies reveal modes of macroevolution in RNA viruses. |
|
|
|
| Further, methods are shared by paleontologists and neontologists, and this allows direct communication on the patterns and processes of macroevolution. |
