" I was warmly amused at the way each one tried to outdo the others in showing how her ape was the “most human”—trying to win the audience over to favor her animal. Orangutans, Biruté said, seemed the most human because of the whites of their eyes. Dian insisted that her gorillas were most humanlike because of their tight-knit family groupings. And Jane reminded us that chimps are the apes most closely related to man, sharing 99 percent of our genetic material. I was reminded of kids who insist “my dad can beat up your dad,” or of grandmothers comparing their grandchildren. None of the women would ever think of disparaging the others’ work, but each is firmly convinced that the animals she loves are the best. For they do love them. "
