- Accidents in small populations can change the frequency of some genes in a population.
- This is known as Genetic Drift .

- But when the elephant stepped on the population of beetles, beetles of one characteristic accidentally survived .
- This is not a survival advantage .
- But, this can result in the emergence of new species .
