"That's when I consciously thought about the fact that this can't be by chance, there must truly and honestly be something behind the universe." Hope for the futureĭr Goodall is still pushing boundaries as a conservation leader and activist – and she's still cultivating an extraordinary capacity for curiosity, wonder and hope. "It all came together then … the amazing path through history of the couplings, of people meeting, marrying, having children, that eventually led to Bach, the brilliant mind that created that glorious music. "As I was looking at the sun coming through the window, suddenly the amazing organ started up with Bach's Toccata and Fugue in G minor. ![]() "The sun was just rising and shining through the glorious rose window," she says. Specifically, they suggest greater continuity between chimpanzee and human cultural evolution than is normally assumed and that the human capacity for cumulative culture may have a shared evolutionary origin with chimpanzees.Dr Goodall was in Paris's Notre Dame Cathedral one morning in the 1970s, when she experienced a moment of spiritual enlightenment. "Our findings on wild chimpanzees, our closest living relatives, help to shed light on what it is (and isn't!) that makes human culture unique. The presence of a model from whom to learn appears to be the missing piece. "Our findings suggest that chimpanzees acquire cultural behaviors more like humans and do not simply invent a complex tool use behavior like nut cracking on their own," says Koops. Shared evolutionary origin of cumulative culture Only one female chimpanzee was observed eating from the palm fruit, but on no occasion did the chimpanzees crack or eat either oil palm or Coula nuts. The chimpanzees were more likely to explore the experiments when visiting in bigger parties. A total of 35 chimpanzee parties (or sub-groups) visited the experiments, of which 11 parties closely investigated the experimental items. The chimpanzees visited the nut cracking experiments and explored the nuts and stones, yet they did not crack any nuts, even after more than a year of exposure to the materials. And finally, the chimps were presented with another, easier-to-crack species of nuts ( Coula) together with stones. In the third experiment, the nuts were cracked open and placed on top of the stones. Next, the researches added a palm fruit to the experimental setup. First, the chimps were presented with oil palm nuts and stones. The chimpanzees were presented with a series of four experiments. The primatologist investigated whether wild chimpanzees can in fact invent a complex behavior like nut cracking independently. UZH professor in the department of Anthropology Kathelijne Koops has now carried out novel field experiments in the Nimba Mountains of Guinea to show that this may not be the case. According to the zone of latent solutions hypothesis in Anthropology, chimpanzees do not learn in this way, but can reinvent cultural behaviors individually. As such, human culture is cumulative, since skills and technologies accumulate over generations and become increasingly efficient or complex. ![]() Humans have a complex culture that enables them to copy behaviors from others.
