The author probably intends to show off his research on genetics instead of composing a solid sensible story. He spent too much time depicting various scenes which are not well linked and paved for the story development. I don't feel like turning the page continuously. In his other book State of Fear, he involved the cannibals (goodness… what a lousy idea!); and in this book he inserts an orangutan, humanzee (human + chimpanzee breed) and a talking parrot who could think and speak like human being. Another lousy idea… Not recommended.
