Question

Some scientists have been concluded that the legs of modern land vertebrates evolved from the fins of ancient fish. What most likely provided the evidence for this conclusion?
- study the fossils of ancient land vertebrates

- Identity the numbers of ancient fish and ancient land vertebrates

- comparing the number of genes in modern fish to the number of genes in modern land vertebrates

- comparing the movements of genes in modern fish fins to the limbs of modern land vertebrates

Answer 1

Answer:

1- study the fossils of ancient land vertebrates

Explanation:

Some scientists concluded after performing a number of experiments that the legs of modern land vertebrates evolved from the fins of ancient fish. With the passage of time evolution occurs within the body of organisms. These changes occurs due to the surrounding environmental condition of that organism. When the organisms live in water, fins were present but when they go to the land so these fins change into legs. This type of evidence is provided by the scientist after studying the remains of ancient land vertebrates.
