Why is there different kinds of hair and eye colors?

Question

I know is due to evolution BUT why, was the use of lets say having red hair and blue eyes how could that help in our evolution??

And why is it that eye colors have a wider range in women than men ??

Answer 1

I personally am a Christian so Evolution doesn't work for me.

BUT! Here's what happens: Since eye color and, to a lesser extent, hair color have minimal impact on survival then it's very likely that they exist simply because they haven't been bred out of us. Also, since certain hair and eye colors are more sexually attractive those colors are able to survive for long periods of time even if they are recessive, blonde hair and blue eyes for instance.

Why they're more varied in women than men. IDK if that's true or not but I would venture to say that theirs not much statistical difference between the rarity of a blonde girl and a blonde guy. What would be more likely in my opinion is the fact that blonde girls are more likely to be noticed than blonde boys and that guys are less picky about the difference between dirty blonde and say light brown. {Like Red and Strawberry Blonde...WTFlip is the difference?}

Answer 2

Because if we didn't have variety, we'd all look like the Baldwin brothers.

Answer 3

It's all about the pigments, If you have brown hair then there is a good chance you have brown eyes. But there are genes that are more likely to show up than others. For instance if your mom had blue eyes and your dad brown eyes then you would have brown eyes because that is the stronger genes.

Answer 4

Natural selection, its in your genes, it just depend on your phenotypes.

Answer 5

Different skin colors and eye colors result from the environment different races of people adapted to.  It's mostly to do with the amount of sunlight those people get. People of African descent have black hair and dark eyes because those are best adapted to surviving in the harsh sunlight that is found in the desert and near the equator.  People of European descent hair lighter colored skin and eyes because the amount of sunlight found that far from the equator did not force them to adapt with darker pigments.  

I don't think women have a wider range of eye colors than men.  There are actually only two genetically different eye colors, brown and blue.  All other colors are just slight derrivations of these two.  For example, green, hazel, and black are all derrivations of the brown genes for eye color while eye colors such as gray or silver are derrivations of blue.  Eye and hair color are results of environmental adaptations, not for attracting mates, so there is no reason for men and women to have different frequencies of eye color variations.
