1. Evolution Review

2. A farmer sprayed his fields with a new insecticide to rid his crops of grasshoppers. Twenty-four hours later nearly all the grasshoppers were dead. A few, however, survived. Each year he continues to spray his fields with the insecticide, but fewer and fewer of the grasshoppers die. Which of the following best explains the results? A. The insecticide caused a mutation in the species. B. The grasshoppers learned to fight off the insecticide. C. The insecticide caused a side effect of immunity that was passed on to the next generation of grasshoppers. D. A few grasshoppers in the first population were immune and passed this trait to their offspring.
