Ever notice how city Pigeons are darker than their countryside cousins?
Thatβs Evolution in action.
Darker pigeons carry more Melanin,
Natureβs built-in detox agent.
City air is laced with heavy metals. Melanin binds these toxins and locks them into feathers. When the pigeons molt, they literally shed the pollution off their bodies.
This is why they're better at managing the toxic load that city life brings.
Over generations, this means more dark pigeons survive and reproduce, which explains why urban populations tend to be darker than rural ones.
