| 11. | Goldschmidt thought that small gradual changes could not bridge the hypothetical divide between microevolution and macroevolution.
|
| 12. | As biologists define " macroevolution ", both microevolution and macroevolution have been observed.
|
| 13. | Microevolution over time leads to speciation or the appearance of novel structure, sometimes classified as macroevolution.
|
| 14. | The core of the debate for me, therefore, is the extrapolation of microevolution to macroevolution ."
|
| 15. | This acceptance of " microevolution " only within a " kind " is also typical of old Earth creationism.
|
| 16. | "' Microevolution "'is the change in allele frequencies that occurs over time within a population.
|
| 17. | Population genetics is the branch of biology that provides the mathematical structure for the study of the process of microevolution.
|
| 18. | Typically, observable instances of evolution are examples of microevolution; for example, bacterial strains that have antibiotic resistance.
|
| 19. | Macroevolution includes changes occurring on geological time scales, in contrast to microevolution, which occurs on any time scale.
|
| 20. | These differences in diet and foraging behavior between coastal and inland snake populations suggest that the species has undergone microevolution.
