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.

kakasveta [241]

Answer:

The correct answer is: False.

Explanation:

  • A Fishery collapse can be defined as the condition in which the composition of different species of fishes forming a food chain or a food web and located in a marine or aquatic community undergoes a drastic alteration.
  • The alternation can be caused due to environmental or anthropological factors.
  • A fishery collapse usually affects the larger fish population like sharks and tuna as their commercial and economic demand is higher.
  • Excessive fishing cause the population of the large fishes to decline without affecting the small fish population.
  • This is because the small fishes do not have high economic or commercial demand, hence they have very less probability of being angled or captured.
