The Dark Side of Darwin's Legacy

Should we reassess Darwin's legacy?
(...)He asserted that different races of mankind had traveled different distances along the evolutionary path — white Caucasians were at the top of the racial hierarchy, while black and brown people ranked below. [Racism] was a widespread prejudice in British society at the time, but he presented racial hierarchy as a matter of science. He also held that the poor were genetically second-rate — which inspired eugenics.

We understand now that eugenics was an illegitimate science, so why even worry about it today?
The thinking behind eugenics is still present. Many senior geneticists point to a genetically engineered future. As the technology for this falls into place, there has also been an explosion of the field of evolutionary psychology that tries to describe every element of human behavior as genetically determined. What we will begin to see is scientists arguing for the use of genetics to breed out certain behavioral traits from humanity.
