You couldn't be more wrong, Mr. Moron.
First of all evolution is not called "Darwin's teachings".
Evolution is called "evolution".
The difference in human skin colors is as insignificant as the differences in cow colors. It doesn't matter, it's just minor differences in a small number of genes. Each human race has developed to have the best possible skin color for the environment that race came from. Look it up for the details. Find out why racist biologists don't exist. Meanwhile there's the Ku Klux Klan which is a Christian organization.
Also it's interesting that while Christians used their worthless Bible to justify slavery, Darwin spoke out strongly against slavery.
If everyone was educated about evolutionary biology there would be no racists in the world.
