Question

have tails with dull coloring.

which concept is demonstrated by a decrease in dull coloring?
○ speciation
○ biodiversity
○ natural selection
○ variation

Explanation:

A decrease in dull tail coloring in peacocks implies that males with more vibrant tails are more successful at mating and passing on their genes, as females select for these traits. This is a classic example of natural selection, where traits that improve reproductive success become more common in a population over time. Speciation refers to the formation of new species, biodiversity is the variety of life, and variation is the presence of different traits, none of which directly describe the reduction of dull coloring due to reproductive advantage.

Answer:

natural selection
