a. Marine stickleback fish had heavy armor.
b. Some freshwater environments became closed systems of lakes with few or no predators.
c. Marine sticklebacks carrying the recessive low-armor Eda mutation spread into freshwater habitats.
d. In freshwater lakes, sticklebacks with less armor produced more offspring than sticklebacks with more armor.
e. A mutation in the Eda gene gave rise to the low-Eda allele, resulting in variation in armor plating.
f. Most stickleback populations in lakes evolved a predominance Of light armor.
