Her moment of international recognition came with the broadcast of the documentary 'Miss Goodall and the Wild Chimpanzees' across the United States. However, Goodall's career hasn't always been embraced by society. As discoveries were made establishing the real biological and behavioural similarities between chimpanzees and human beings, the resistance in both the press and general public grew, the main point of contention being how a woman - without a university degree - could make such claims about humanity. As science backed the facts Goodall continued to uncover, those issues were more or less laid to rest; but the peoples' trust in science and what studying chimpanzees could tell us about humanity, especially whether aggression was an innate trait or something learned, was a real political predicament. 'At that time, in the early 1970s, it was a political issue. Science was divided as to whether human infants are born with a clean slate, everything is learned from your culture, your society, from your mother ...

In light of an upcoming visit to chimpanzee sanctuary Ngamba Island, Goodall also recalls the maltreatment and abuse of primates at the Entebbe zoo when she first visited Uganda under then-president Idi Amin's rule. 'They [Entebbe zoo] had about eight or nine infa
