the author of my book is dead

"Ten yards. Hagar held the microphone out in front of him. The tourists were pulling out their cameras. The orang stared directly at Hagar and made an odd sound like a cough. "Dwaas." Hagar repeated the sound back. "Dwaas." The orang stared at him. The curved lips moved. A sequence of guttural grunts: "Ooh stomm dwaas, varlaat leanme." One of the tourists says, "Is he making those sounds?" "Yes," Hagar said. "Is he....talking??" "Apes can't talk," another tourist said, "orangs are silent, it says so in the book." A man pointed at the orang. "That's Dutch, " he said." (43)
In this excerpt, a group of tourists, led by a guide, venture into an orangutan-populated part of the jungle, and an orangutan begins speaking. The author introduces the topic of mixing genes between different species, and allows the reader to assume that perhaps, this orangutan has human genes introduced to it. Orangutans are our closest relative, so intertwining human genes with those of orangutans wouldn't be impossible. Is this orangutan really part human? What role will it play in the story? Does the orangutan pose a threat?
