1. What is NOT vestigial structure for humans?
2. A process in which 2 species evolve in response to changes in each other.
3. The method of scientific classification used today is based on the classification system developed by

This leads to a reduction in the variation of the trait in the population over time, as individuals with extreme traits have lower fitness and are less likely to survive and reproduce.
