From Chronicles:
ShareOne day in the 1960s, in a forest in Tanzania, a 26-year-old British ethologist watched a chimpanzee she had nicknamed “David Greybeard” digging termites out of a mound with a stick. Birds had long been known to use “tools”—Egyptian vultures drop stones onto eggs to crack them open, and Darwin had seen finches on the Galapagos Islands using cactus spines to pry insects out of wood. But Jane Goodall was astounded to see a mammal doing something similar. It strengthened in her mind something that had often been surmised—that chimpanzees were proto-humans, us as we used to be millions of years before we diverged into Australopithecus, Neanderthal, and, finally, Sapiens.
Humans have always been fascinated by primates. African animists worshipped gorillas as gods, the Dayaks of Borneo saw orangutans as near-kin (“orangutan” means “people of the forest”), and Westerners encountering primates after the 16th century embraced them as pets and circus animals. We would later derive endless entertainment from the likes of King Kong, Tarzan, Planet of the Apes, and 2001: A Space Odyssey. Linnaean taxonomy and Darwinian evolution can even be seen as systematizations of an ancient obsession with the “wild men” of legends—hirsute forest-dwellers both disconcertingly familiar and dangerously fey.
Goodall had been a student of the paleoanthropologist Louis Leakey, originator of the “out of Africa” theory of human evolution, who was likewise fascinated by the great apes. Other 20th-century influencers famously interested in apes included Robert Yerkes, the once-celebrated psychologist who devised intelligence tests for the U.S. Army, and whose 1925 book Almost Human recounted his delight in the company of Prince Chim, an “intellectual genius” of a bonobo, with whom he shared his New Hampshire home.
Growing liberalization and secularization of thought over the 20th century would encourage new ways of viewing ourselves and animals. By 1965, Goodall was on the cover of National Geographic, celebrating the chimpanzee as an almost-person—no mere bundle of Brownian instincts, but a distant cousin, whose obvious skeletal similarities were mirrored by humanlike behavioral traits. (Goodall herself was careful never to read too much into chimpanzees’ apparent “emotions,” however.) (Read more.)
