The Human Genome Project came to this conclusion: only one biological race exists. All humans in the world today are classified as Homo sapiens sapiens (same genus, species, and subspecies). When the Human Genome Project published a draft of their findings in 2000, the New York Times reported that "the researchers had unanimously declared there is only one race—the human race."
All humans basically have the same skin color—a brown pigment called melanin. Although there are a couple of forms of melanin and other pigments and factors playing minor roles in skin color, every human basically has a brown color.
Lots of brown is called black, and a little brown color is called white. In actuality, no human really is "black" and no human is "white." There are not different colors but different shades of one basic color, brown.
While many factors are involved in determining skin color and the steps are very technical, basic genetics can help us understand the most important principles.
DOMINANT GENES result in lots of melanin and RECESSIVE GENES result in little melanin.
One might say: "I'll believe we are all one race when you can show me two black people having a white baby and two white people having a black baby."
OK, here you go:
A few documented examples of fraternal twins being "black" and "white" include:
1. The Hodgson-Horder twin girls (Born April 2005 in England)
2. The Biggs twin girls (Born July 2006 in Australia)
3. The Richardson twin boys (Born July 2006 in England)
4. The Grant twin girls (Born 1983 in England)
5. The Singerl twin girls (Born May 2006 in Australia)…Look them up.
So, it's not just "black" and "white." Bottom line: a person's skin shade (what is on the outside) should in no way invoke any sort of prejudice or racist comments.
Sure, most people suck, but their skin color has nothing to do with it. It's who they are as Individuals that determine their worth.
All this to say Racism is one of the most easily argued down points of view when presented with documented scientific facts. A point of view based on self-hatred, misplaced narcissism and misdirected blame.
