“It is as important that the right people should be born as that the wrong people should not be born. By the ” right people ” I mean not those who, in Herbert Spencer’s phrase, are the “fittest to survive,” but those who give most promise of ” civic worth,” that is to say, will be most likely to be at once useful to themselves in the way of enjoyment and self-support, and also useful to the community at large. Sound health, a sufficient amount of energy, a well-balanced brain, are obviously desirable, nay, necessary ingredients-good moral training should supply the rest. ” Crackanthorpe 1909
Descent with modifications is the idea that offspring will be slightly different from their parents. These differences we now know are due to random mutations and patterns of inheritance. When you hear the word mutation most of us think cancer or some other disaster which is a definite possibility, but mutations can sometimes lead to positive changes. No, unfortunately we are not talking the Marvel movie type of positive changes. We aren’t about to be hanging out with Magneto or Wolverine anytime soon, but if you ever decide to procreate just know you will be producing you very own little mutant.
