In the process he documented some of the crimes of the eugenics movement and the monstrous atrocities committed by German National Socialism in the name of eugenics and biology, while noting the Nazi’s promotion of twin research.

Cooper-White concluded that the results of this study indicate that the nature-nurture debate “may now be over.”
