Is skin changing color possible?
Eventually, your skin returns to its normal shade. For some people, though, skin can change color and stay that way. People with a condition known as vitiligo (pronounced vit-uh-LIE-go) experience patches of skin that suddenly turn white, as if they’ve lost all pigmentation.
How did skin color evolve?
Pigmentation, (skin color), in humans has evolved under selection pressure from the duration and intensity of sunlight. Ancestral populations near the equator were selected for dark skin, while those living in higher northern latitudes were selected for lighter skin.
What skin color is the most attractive?
A new study by Missouri School of Journalism researcher Cynthia Frisby found that people perceive a light brown skin tone to be more physically attractive than a pale or dark skin tone.
How often does skin color change in lineages?
Skin pigmentation in human lineages has changed faster and more frequently than scientists previously thought, one expert says. A population can be one color, and 100 generations later, with no intermarriage, can be a very different color. You have to define change of skin color.
Why did we evolve different skin colors?
The Sepia Rainbow In the early 1990s, the evolution of skin color was regarded by many of her peers as an intractable problem. Theory held that darker skin had evolved in order to afford early humans—who had recently lost the cover of fur—a protection against skin cancer under the tropical sun.
Is it possible to change your skin colour by natural selection?
So, particularly in the case of people whose skin is already dark, there would be no effect of changing skin-colour that would make them less likely to die before providing offspring, and therefore it wouldn’t happen by natural selection. However, that’s just the physical side of things.
Can you change the color of a baby’s skin?
Modify the chemical “formula” of one of the skin-color genes, and then the baby that comes from that germ cell will have a different color. It probably will be a small change. Later on, somebody already carrying that gene will get hit by a cosmic ray and the resultant baby will have another color change.
