Question
The diagram below represents one possible evolutionary change that could have led lobe-finned fish to develop into the first amphibians. Amphibians are animals that live on land some of their life.
This change from fins on the lobe-finned fish to legs and feet on the early amphibian is most likely due to

Answers

The most likely explanation for the change from fins on lobe-finned fish to legs and feet on early amphibians is:
**variations among offspring, followed by natural selection.**
This response aligns with the principles of evolution, where genetic variations within a population are subject to natural selection, leading to adaptations that enhance survival in a changing environment. In this case, those variations that favored movement onto land may have been selected for, eventually leading to the development of legs and feet in amphibians.
