How does a mutation cause a population to change over time?

• Mutations are harmful and usually end in death of an organism
• If a mutated trait results in a successful trait, that trait will most likely be passed on to the next generation and so on.
• Mutations help an organism live longer.
• Mutated traits usually result in a super trait that is always beneficial.

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? 

• The insecticide caused a side effect of immunity that was passed on to the next generation of grasshoppers.
• A few grasshoppers in the first population were immune and passed this trait to their offspring.
• The insecticide caused a mutation in the species.
• The grasshoppers learned to fight off the insecticide.
