Arrange the steps of natural selection to describe the evolution of armor among stickleback fish in freshwater lakes. 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.
