I remember a documentary (I think it was produced by the NGC) about bonobos, I believe (OK, not chimpanzees, but close enough).
One of the many things that stand out in my memory is one monkey that apparently was able to relate to the researcher (through sign language) the
death of his mother who was killed (by humans, who else?) when s/he was a baby.
The monkey was still traumatised by it (duh!).
But it was the fact that s/he was able to recount that grief what struck the researchers the most.
(I suppose that speaks volumes - and not necessarily positively - about humans and their solipsist perception of other living beings...)
