Junk DNA goodbye!: neutral DNA is shown as smaller (Introduction)

dhw: I know the junk theory, and I know that it is being increasingly discredited. You asked who are what is doing the selecting (i.e. of useful DNA). I suggested that it is natural for something useful to survive and for something that is not useful not to survive. What is your objection?

DAVID: The point is the reliance on 'survival of the fittest', which is what you just did, is a very minor unproven aspect of evolution. Your statement is correct if understood in the right context.

You asked who or what did the selection. Since the context is useful DNA versus junk DNA and you accept that it is natural for something useful to survive and for something that is not useful not to survive, there is no disagreement here.
