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.
