1. Macro-/Microevolution
Macroevolution
1. Large-scale changes in gene frequencies
2. Longer time period
3. At/above level of species
4. Extended microevolution
5. Not directly observed
6. Fossil Evidence
7. More controversial
8. Eg reptiles  birds
Microevolution
1. Small-scale changes in gene frequencies
2. Few generations
3. Within species / population
4. small evolutionary changes
5. Observable
6. Experimental evidence
7. Less controversial
8. Eg Bacterial resistance to antibiotics
Macro-/Microevolution

2. Macro- / Microevolution

3. Microevolution – dog breeds
Bred for certain traits
Changes in size, shape, and color—or minor genetic alterations
NOT macroevolution (adaptative) 
Microevolution – dog breeds

4. Patterns of Macroevolution
Species
Unrelated
Related
Intense environmental pressure
Inter-relationships
