I'm not sure which category this falls under, but it has a medical basis, so I guess here is as good as anywhere.

I keep seeing all of these issues with race and racism everywhere, and I find them very unsettling. Our skin color is nothing more than the adaption of man to his environment.

So many people judge others based on the color of the skin, rather than their personal integrity, and values. I get so fed up with comments like, "All blacks/whites/Arabs/etc. are the same. They are all thieves/liars/untrustworthy/etc."

So much evil and pain has come from people's hatred for each other based on the pigment of their skin. An even more unfortunate result of this short-sightedness, though, is the loss of camaraderie and unity that mankind could have achieved, were they not limited by their distrust of anyone that appears different.

I know that a lot of people have other "excuses" for why they dislike people of other races, but it all seems to go back to the matter of skin color.

So, for those of you who may not already be aware of how we all came to have our various skin tones, this is how it worked:

Skin color is determined by the amount and type of the pigment melanin in the skin. Melanin comes in two types: phaeomelanin (red to yellow) and eumelanin (dark brown to black). Both amount and type are determined by 4-6 genes which operate under incomplete dominance. One copy of each of those genes is inherited from the father and one from the mother. Each gene comes in several alleles, resulting in a great variety of different skin colors.

In general, people with ancestors from sunny regions have darker skin than people with ancestors from regions with less sunlight. (However, this is complicated by the fact that there are people whose ancestors come from both sunny and less-sunny regions; and these people can have skin colors across the spectrum.)

Dark skin evolved to protect people in sunny regions against skin cancer, mutations in skin cells induced by ultraviolet light. Light-skinned persons have about a tenfold greater risk of dying from skin cancer under equal sun conditions. Furthermore, dark skin prevents UV-A radiation from destroying the essential B vitamin folate. Folate is needed for the synthesis of DNA in dividing cells and too low levels of folate in pregnant women are associated with birth defects.

While people who lived in colder, less sunny places developed light skin because it lets more sunlight through, which leads to increased production of vitamin D3, necessary for calcium absorption and bone growth. .
When humans migrated to sun-poorer regions in the north, low vitamin D3 levels became a problem and light skin color evolved. Dark-skinned people who live in sun-poor regions often lack vitamin D3, one reason for the fortification of milk with vitamin D in some countries

Also, women generally have lighter skin than their male counterparts. This results either from sexual preference or from the higher calcium needs of women during pregnancy and lactation. en.wikipedia.org...

So, to anyone who judges by appearance first, rather than by personal integrity, PLEASE STOP! Our planet can't take much more intolerance and hatred. We're on the verge of destroying ourselves as it is, If we don't start learning to love each other for our differences (this goes for all religious bigots as well) we are not going be around much longer.
