Macroevolution
1. Intra-species genetic change
1. Changes leads to formation of a completely new species.
2. Occurs over small-time scale.
2. Occurs over large time-scale.
3. Genetic information that already exists is put in new arrangement, altered or lost.
3. New information is added to the existing genetic structure.
4. Changes in the gene pool of a population.
4. Macroevolution is the result of a lot of microevolution over a long period of time.
5. E.g., new breeds of dogs
e.g., Amphibians to reptiles
