Chimpanzee Baby Adopted By A Mastiff Dog

Recent studies have shown that chimpanzees engage in apparently altruistic behaviour within groups, but are indifferent to the welfare of unrelated group members.
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.
• Communication
Chimps communicate in a manner similar to human non-verbal communication, using vocalizations, hand gestures, and facial expressions. Research into the chimpanzee brain has revealed that chimp communication activates an area of the chimp brain that is in the same position as Broca's area, the language center in the human brain.
