That image nails the mood: a stylized, war-like jungle standoff with chimps using branches as weapons, which fits your thread’s core point even if it’s obviously artistic rather than documentary. The underlying story is real — reports on April 9–10 describe a long-running split in Uganda’s Kibale National Park that turned into lethal factional violence after a once-large community fractured, with researchers framing it as unusually clear evidence of chimp group fission escalating into organized conflict (Yahoo News, Apr 9, ABC News AU, Apr 10). Your InLeo post already captures the sharp part: when territory, hierarchy, and mating access get squeezed, primate politics gets nasty fast (your thread).
