Loretta clocked Dr Parish and made an instant beeline towards her. The bonobo stood upright on the other side of the glass, her soulful amber eyes stared deeply into Parish’s and she made a succession of subtle nods with her head. Parish nodded back using the same shared language of acknowledgement. Loretta then leaned into the glass, placing her head against it. Parish did the same and the two mock-groomed one another through the glass for over twenty minutes. At one stage Loretta placed her hand on the glass and the scientist placed hers against the bonobo’s, as if the glass were not there.
