Then are you working with the entire DNA strand?" Grant asked. "Oh no," Wu said. "That's impossible. We've come a long way from the sixties, when it took a whole laboratory four years to decode a screen like this. Now the computers can do it in a couple of hours. But, even so, the DNA molecule is too big. We look only at the sections of the strand that differ from animal to animal, or from contemporary DNA. Only a few percent of the nucleotides differ from one species to the next. That's what we analyze, and it's still a big job.
