The statement that best models Darwin's theory of natural selection is 'A'.
Explicación
## Step 1Darwin's theory of natural selection, also known as survival of the fittest, is a concept in biology that explains how species evolve over time. According to this theory, individuals within a species who possess traits that are advantageous for their environment are more likely to survive and reproduce. These advantageous traits are then passed on to their offspring, leading to the evolution of the species over time.## Step 2Looking at the options provided, we need to identify which one best models this theory. ## Step 3Option A describes a situation where a population of peppered moths with darker coloration are better camouflaged against soot-darkened trees. This is a clear example of natural selection, as the darker coloration provides a survival advantage in the soot-darkened environment.## Step 4The other options do not accurately represent Darwin's theory of natural selection. For example, option B describes a population of rabbits evolving over one generation to develop longer ears to hear predators more effectively. This is not an example of natural selection, as the change in ear length is not passed down to future generations.## Step 5Similarly, option C describes a species of bird growing larger beaks after a drought, but these changes are not passed down to future generations. This is not an example of natural selection, as the change in beak size is not inherited.## Step 6Finally, option D describes a group of giraffes with longer necks being able to reach higher leaves, but they do not reproduce because of competition. This is not an example of natural selection, as the change in neck length is not passed down to future generations.
