Level	Species level	All taxon levels
Scale	Small-scale	Large-scale
Species	Within species	Between species
Period	Few generations	Longer periods of time that span up to eras.
Factors	Mutation, Selection, Gene flow, Genetic drift.	Extended microevolution
Basis	Molecular level	Fossil data
Occurs when	Always	High post mass extinction
