Other changes occur as well, when current moth mates with its ancestor moth, no viable eggs are produced.

Incident 2: A species of frogs is living in a pond near an earthquake fault line. An earthquake separates the frog population into two separate populations. After hundreds of years, the two population are not able to mate.

Based on the second incident, mating between two groups of frogs is not possible as they have now become different:
