Chimps, Humans 96 Percent the Same, Gene Study Finds

"If genetic code is a book, what we found is that entire pages of the book duplicated in one species but not the other," said Eichler. "This gives us some insight into the genetic diversity that's going on between chimp and human and identifies regions that contain genes that have undergone very rapid genomic changes."

I am not able to understand the meaning of "duplicated in one species but not the other" clearly. Does it mean "duplicated in humans but not chimps" or "duplicated in chimps but not humans"?

I would say that there is an "are" missing before "duplicated".
From the part that you have quoted, it is not clear to me exactly what the author means. It would, I think, be necessary to read the whole article.

Either one.

(I'm sure you thought you could understand the answer or you wouldn't have asked the question.)
