📚 RESEARCH & SOURCES:
▸ The killer ape idea: "The Predatory Transition from Ape to Man" by Raymond Dart (1953, International Anthropological and Linguistic Review). Smashed cave bones read as proof we were born killers.
▸ SK 54 and the leopard jaw: "The Hunters or the Hunted? An Introduction to African Cave Taphonomy" by C.K. Brain (1981, University of Chicago Press). The two holes in the SK 54 skull match the lower fangs of a fossil leopard jaw from the same cave.
▸ SK 54 belongs to early Homo: "We the hunted" by Martin, Leece, Herries, Baker & Strait (2024, South African Journal of Science) the leopard's victim was early Homo, the group that leads to us.
▸ The Taung Child and the eagle: "Predatory bird damage to the Taung type-skull of Australopithecus africanus" by Lee Berger (2006, American Journal of Physical Anthropology) punctures in the eye sockets match crowned eagle kills.

▸ Fire at Wonderwerk Cave: "Microstratigraphic evidence of in situ fire in the Acheulean strata of Wonderwerk Cave" (2012, Proceedings of the National Academy of Sciences) burned bones and plant ash from about 1 million years ago.

▸ The oldest spear tip: "A reappraisal of the Clacton spearpoint" by Oakley et al. (1977, Proceedings of the Prehistoric Society). A wooden spear tip from England, about 400,000 years old.
▸ Schöningen spears re-dated: "Revised age for Schöningen hunting spears indicates intensification of Neanderthal cooperative behavior around 200,000 years ago" (2025, Science Advances)
▸ Spears built to be thrown: "External ballistics of Pleistocene hand-thrown spears" by Annemieke Milks et al. (2019, Scientific Reports) : javelin throwers hit targets up to 20 meters away.

PEOPLE & SITES MENTIONED IN THIS VIDEO:
▸ Raymond Dart: Anatomist who saw weapons in broken cave bones and gave us the "killer ape" story of human origins.
▸ C.K. Brain: Studied Swartkrans for years and showed the bones in the cave were a leopard's leftovers, not a killer's trophies.
▸ Swartkrans: A South African cave where leopards ate in trees above the openings and the bones fell inside. Home of SK 54.
▸ Taung: The quarry in South Africa where the Taung Child was found in 1924, one of the first early human relatives ever found in Africa.
▸ Lee Berger: Paleoanthropologist who found eagle talon damage in the Taung Child's eye sockets in 2006.
▸ Olduvai Gorge: A canyon in Tanzania where Jackson Njau showed crocodile bite marks on our relatives' leg and foot bones from about 1.8 million years ago.
▸ Wonderwerk Cave: A cave in South Africa holding some of the oldest solid evidence of fire, about 1 million years old.
▸ Schöningen: A coal mine in Germany where about ten complete wooden weapons were found, preserved in wet mud for about 200,000 years and most likely made by early Neanderthals.
▸ Liana Zanette: Ecologist who played lion growls and human voices at 21 waterholes in Kruger National Park and found animals feared us more.
▸ The Dorobo: Hunters in Kenya filmed for BBC's Human Planet walking straight into a pride of lions to take their meat.
