Extra regression practice: bald eagles
The population trend of the bald eagle during the past 70 years provides a history with several
important lessons. After World War II, the insecticide, dichlorodiphenyl-trichloroethane (DDT),

In Chapter 10 Nye discusses how humans edit their surroundings (plants and animals) in order to
suite their wants. He discusses the differences between artificial selection and natural selection
by stating that artificial selection serves a humans needs w

the concept of linkage.
Linkage, or genetic linkage, pertains to genes that are located close together on the
same exact chromos
