which of the following statements depend on the relative dating of events? 1.amphibians evolved before land reptiles.
2. bony fish first evolved about 420 million years ago.
3.the jurassic period began 200 million years ago.
4.elephants appear in the fossil record after dinosaurs became extinct

The correct answers are options:

1. Amphibians evolved before land reptiles.

4. Elephants appear in the fossil record after dinosaurs became extinct.

The relative dating is a technique of dating with respect to any past event. In this case, two events are discussed to be occurred in a sequence related to one-another. In the option 1, the amphibians are said to be evolved before reptiles. So, the evolution of the amphibians is relatively dated with the evolution of reptiles. Same in the option 4, the evolution of the elephants is relatively dated with the extinction of the dinosaurs.
