I disagree. Chimpanzee, intelligence and self awareness are pretty well developed and documented. Below is an excerpt from Wikipedia about chimpanzee intelligence:

Evidence for "chimpanzee spirituality
" includes display of mourning
, "incipient romantic love
", "rain dance
", appreciation of natural beauty such as a sunset over a lake, curiosity and respect towards wildlife (such as the python
, which is neither a threat nor a food source to chimpanzees), empathy toward other species (such as feeding turtles) and even "animism
" or "pretend play" in chimps cradling and grooming rocks or sticks.
