Fossils of extinct corals are commonly found in Pennsylvania . Scientists who study these coral fossils indicate that they are similar to living corals . Which statement best explains why these fossils provide valuable information about prehistoric Pennsylvania?

• They may indicate that the earliest settlers moved inland from the coasts and brought coral-based fertilizer for their crops .

• They may provide evidence for evolution by comparing adaptations for living on land with aquatic adaptations in the same species

• They may indicate that corals may have lived on land at some point in history because corals presently live in aquatic environments .

• They may provide evidence that Pennsylvania was once covered by warm ocean waters since most corals are presently found in these environments
