Cheryl Knott, a biological anthropologist who studies orangutans in Gunung Palung National Park in Indonesia, made her own startling discovery about the similarities between humans and these shaggy red-haired great apes. “[W]e and orangutans are so similar that Knott can use standard drugstore test kits on urine from female orangutans to determine whether they’re pregnant,” reported National Geographic.
