Question

How does natural selection explain the differences in coloration between inland and coastal guppies?

Inland guppies evolved muted colors for camouflage, while coastal guppies developed muted colors because predators in clear water prefer bright colors.

Inland guppies evolved bright colors to signal good health, while coastal guppies evolved muted colors for camouflage.

Inland guppies evolved bright colors to blend into the local vegetation, while coastal guppies evolved muted colors to signal good health and attract mates.

Inland guppies evolved muted colors to blend into dense vegetation and avoid predators, while coastal guppies evolved bright colors to improve mate attraction and visual communication.

Answer 1

"Inland guppies evolved bright colors to signal good health, while coastal guppies evolved muted colors for camouflage."

Explanation: In habitats with few predators (often upstream/inland), sexual selection favors conspicuous males because bright colors attract mates. In habitats with many visual predators (often downstream/coastal, clearer water), natural selection favors cryptic, muted coloration to reduce predation risk.
