The thoughts of the wicked are an abomination to the LORD...
Proverbs 15:26
"On the last page of his book The Descent of Man, Charles
Darwin expressed the opinion that he would rather be descended from a
monkey than from a “Savage.” 
In describing those with darker skin, he
often used words like “savage,” “low,” and “degraded” to describe
American Indians, people groups from Africa, and almost every ethnic
group whose physical appearance and culture differed from his own.
In
his work, those once called pygmies have been compared to “lower
organisms” and were labeled “the low integrated inhabitants of the
Andaman Islands.”
Although racism did not begin with Darwinism, Darwin did more than any person to popularize it.
After Darwin “proved” that all humans descended from apes, it was natural to conclude that some so-called “races” had descended further than others.
In his opinion, some “races” (namely the “white” ones) have left the others far behind, while other races (especially certain groups from Africa) have hardly matured at all.
The subtitle of Darwin’s classic 1859 book, The Origin of the Species, was The Preservation of Favoured Races in the Struggle for Life. The book dealt with the evolution of animals in general, and his later book, The Descent of Man, applied his ideas to humans." AIG
