Of the scenarios listed below, which is an example of diversifying selection?
Historically, beach mice were a light beige color that allowed them to blend in with Florida's uniquely colored sand. Over the last 30 years, beach
restoration efforts have delivered darker colored sand to Florida's beaches. Current census of beach mice populations show that many
populations are now a darker color than they were 30 years ago.
None of these scenarios are an example of diversifying selection.
Female robins typically lay four eggs in each clutch. Larger clutches result in chick malnourishment as the parents struggle to feed many chicks
and smaller clutches result in chick mortality as the chicks are less able to keep each other warm when their parents are hunting.
All of these scenarios are an example of diversifyting selection.
Lizards in Florida are either brown green depending on whether they live. The brown lizards tend to live in rocky areas while the green lizards tend
to live in grassy areas. A third color morph, white, is possible but rarely appears.
