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

"This suggests that while most of our genetic material is formed of non-functional sequences, the vast majority of it evolves indirectly under some type of selection."

DAVID: And who or what is doing the selecting?

dhw: Nature, as in natural selection? Whatever is useful will survive?

DAVID: Unless there are extinctions. We don't know what is natural and what is controlled.

Extinctions are the natural consequence of organisms not having the necessary equipment to cope with changing conditions. But we are talking about so-called “junk DNA”. Why do you find it so difficult to accept the idea that something useful is more likely to survive than something which is of no use?
