2. How do mutations change populations over time?
a. Most mutations are harmful and cause species to become extinct
b. Most mutations cause abnormal disease in species
c. Mutations generally have no effect on a population since they are simple changes in DNA

results?
a. The insecticide caused a mutation in the species.
b. The grasshoppers learned to fight off the insecticide.

grasshoppers.
d. A few grasshoppers in the first population were immune and passed this trait to their offspring.
6. The human appendix is a vestigial structure. How is it evidence of evolution?
