The attacks are characterized by extreme violence:
Chimpanzees utilize their sharp, long canines during these assaults.
Victims may suffer severe injuries, including:
Ripping off of body parts such as ears and testes.
Violence likened to human warfare.
Similarities and Differences with Human Warfare
Still unclear whether chimpanzee warfare is a homologous trait shared through common ancestry or a result of similar environmental and selective pressures.
Ongoing debates within the scientific community regarding the evolution of this behavior.
