Social responses to the idea of evolution
Galton's ideas were meant to do good. He said that the human gene pool should be improved by selective breeding policies. This would mean that those who were considered "good stock" would receive a reward if they reproduced.  However, other people added to this, and said those considered "bad stock" would need to undergo compulsory sterilization, prenatal testing and  birth control; and they might even have to be killed.
