baboon

Other wild animals like elephants and baboons also feature in the new series, which is narrated by Sir David Attenborough.

In most mammal species, females live longer -- for example, female baboons and gorillas often surpass males in age.

Indeed, the Jane Goodall Institute now runs a longstanding baboon research project based partly on the fact that baboons are important chimpanzee prey.

Goodall, in removing the barriers, raised primatology to new heights, opening the way for research on subjects ranging from political coalitions among baboons to the use of deception by an array of primates.

Later, the zoo confirmed that it had killed the baboons - none of which were pregnant females or part of scientific studies.
