Question

the image here is a spiny stickleback, with the three spines highlighted with black arrows. The spines are a rigid projection of the external scales. The three-spine stickleback is found in freshwater lakes, but it is rarely found in oceans. Large oceans have spineless sticklebacks that lack these projections. Which component of natural selection is likely driving the change in phenotype distribution of these two sticklebacks in different environments?

Answer 1

The component of natural selection which is most likely driving the change in phenotype distribution is, that the presence of spines on stickleback caused increased food acquisition and survival in ocean areas.

What do you mean by Natural selection?

Natural selection may be defined as a process through which populations of living organisms adapt and change. It involves the favorable variations to carry forward.

Stickleback play a major role in the diet of fish. This structure of fish allows them to feed on small crustaceans and insects.

Therefore, it is well described above.
