Consider the following scenario:
Some fish in a murky underground lake have lighter scales than the others. This makes it slightly harder for the lighter fish to escape detection by predators, but most light-colored fish live long enough to reproduce. A natural event separates the dark-scaled fish from their light-scaled cousins, and as a result, a new species of dark-scaled fish emerges.
Which statement accurately describes the scenario?

The fish survived because of an inheritable advantage.
The fish survived because of an inheritable advantage.
The fish survived because of a non-genetic advantage.
The fish survived because of a non-genetic advantage.
The fish experienced an evolutionary change because of genetic drift.
The fish experienced an evolutionary change because of genetic drift.
The fish experienced an evolutionary change because of natural selection.

The fish experienced an evolutionary change because of natural selection.
The statement that accurately describes the scenario is:
The fish experienced an evolutionary change because of natural selection.
This is because the lighter-scaled fish had a slightly disadvantageous characteristic when it came to predator detection, while the dark-scaled fish were better suited to their environment, leading to eventual reproductive success and the emergence of a new species.

The scenario that accurately describes an example of artificial selection is:
A farmer intentionally breeds oranges to be more resistant to aphids.
This involves human intervention to select and breed specific traits in organisms, which is the essence of artificial selection.
Over many generations, there is a good chance that an advantageous gene will be shared by every organism of the same species or that a new species will emerge. These long-term outcomes are called(1 point)

The long-term outcomes described in your statement are called evolution.
Evolution refers to the process by which populations of organisms change over generations, leading to adaptations and potentially the emergence of new species.
Consider the following scenario:
An animal is born with a shorter tail. This makes no difference to its ability to survive or reproduce, but as a result of pure luck, the animal survives, reproduces, and passes its shorter tail down to its offspring. Over time, the species develops a shorter tail.

The type of process described in this scenario is genetic drift.
Genetic drift refers to random changes in allele frequencies within a population due to chance events. In this case, the shorter tail trait is passed down not because of any advantage or selection pressure, but rather due to luck and the random survival of the animal.
