Why don't peacocks have arms?

Peacocks, like all birds, have evolved from ancestors that lost their forelimbs over millions of years. Instead of arms, they have developed wings that are adapted for flight, although peacocks are not strong fliers. Their evolutionary adaptations have favored traits like their vibrant tail feathers for mating displays, rather than the development of functional arms. This specialization has allowed them to thrive in their environments without the need for arms.
