But why? Why does an onion carry around so much more genetic material than a human? Or why, for that matter, do the broad-footed salamander (65.5 billion bases), the African lungfish (132 billion) and the Paris japonica flower (149 billion)? These organisms don’t appear to be more complex than we are, so Gregory rejects the idea that they’re accomplishing more with all their extra DNA. Instead, he champions an idea first developed in the 1970s but still startling today: that the size of an animal’s or plant’s genome has essentially no relationship to its complexity, because a vast majority of its DNA is — to put it bluntly — junk.
