Vestigial structures do not harm the organism. Nature selects against only harmful traits.

When there is low gene flow
When there is no selective pressure
When there is a bottleneck
Mass extinction
Natural selection occurs when four conditions are met:
1. There is variation among individuals.
2. That variation is at least partially heritable.
3. That variation is linked to differential reproductive success.
4. More individuals are born than can survive and reproduce.
They make the species more genetically diverse

the way that a species creates offspring
directional selection and disruptive selection both decrease genetic variation - apex
