Hominid butchers and biting crocodiles in the African Plio-Pleistocene.

Zooarchaeologists have long relied on linear traces and pits found on the surfaces of ancient bones to infer ancient hominid behaviors such as slicing, chopping, and percussive actions during butchery of mammal carcasses. However, such claims about Plio-Pleistocene hominids rely mostly on very small assemblages of bony remains. Furthermore, recent experiments on trampling animals and biting crocodiles have shown each to be capable of producing mimics of such marks. This equifinality-the creation of similar products by different processes-makes deciphering early archaeological bone assemblages difficult. Bone modifications among Ethiopian Plio-Pleistocene hominid and faunal remains at Asa Issie, Maka, Hadar, and Bouri were reassessed in light of these findings. The results show that crocodiles were important modifiers of these bone assemblages. The relative roles of hominids, mammalian carnivores, and crocodiles in the formation of Oldowan zooarchaeological assemblages will only be accurately revealed by better bounding equifinality. Critical analysis within a consilience-based approach is identified as the pathway forward. More experimental studies and increased archaeological fieldwork aimed at generating adequate samples are now required

Earliest stone-tipped projectiles from the Ethiopian Rift date to> 279,000 years ago

Projectile weapons (i.e. those delivered from a distance) enhanced prehistoric hunting efficiency by enabling higher impact delivery and hunting of a broader range of animals while reducing confrontations with dangerous prey species. Projectiles therefore provided a significant advantage over thrusting spears. Composite projectile technologies are considered indicative of complex behavior and pivotal to the successful spread of Homo sapiens . Direct evidence for such projectiles is thus far unknown from >80,000 years ago. Data from velocity-dependent microfracture features, diagnostic damage patterns, and artifact shape reported here indicate that pointed stone artifacts from Ethiopia were used as projectile weapons (in the form of hafted javelin tips) as early as >279,000 years ago. In combination with the existing archaeological, fossil and genetic evidence, these data isolate eastern Africa as a source of modern cultures and biology

A social archaeology of colonial war in Ethiopia

[EN] The archaeology of twentieth-century warfare, with its focus on Western armies and military issues, has often neglected indigenous experiences of war and social aspects, particularly the role of women in reproducing culture through material practices in situations of great distress. In this article, we propose a postcolonial examination of imperialistic war in Ethiopia. We study the cave of Zeret, the refuge of a large guerrilla group that was massacred by the Italian colonial army in 1939. Using the material evidence available, life underground is described, as well as the military events that led to the destruction of the place and the killing of most of its inhabitants. We argue that archaeology can be a way of revealing, with material facts, the brutality of fascism and colonialism. Finally, drawing upon Spivak and Derrida, we ask: What are the ethical problems of representing the voice of the subaltern? What is the role of materiality in evoking her presence?[ES] La arqueología de la guerra en el siglo XX, al centrarse en ejércitos occidentales y cuestiones militares, ha dejado de lado experiencias indígenas de la guerra y las cuestiones sociales, particularmente el papel de las mujeres en reproducir la cultura a través de prácticas materiales en situaciones de gran estrés. En este artículo, proponemos un estudio poscolonial de la guerra imperialista en Etiopía. Estudiamos la cueva de Zeret, el refugio de un gran grupo guerrillero que fue masacrado por el ejército colonial italiano en 1939. Usando las pruebas materiales, describimos la vida bajo tierra, así como los hechos militares que llevaron a la destrucción del lugar y al asesinato de la mayor parte de sus habitantes. Defendemos que la arqueología puede ser una forma de revelar, con hechos materiales, la brutalidad del fascismo y el colonialismo. Finalmente, basándonos en Spivak y Derrida, nos preguntamos: ¿Cuáles son los problemas éticas de representar la voz del subalterno? ¿Cuál es el papel de la materialidad en evocar su presencia?Peer reviewe

Assessment of complex projectiles in the early Late Pleistocene at Aduma, Ethiopia.

Complex projectiles-propulsion via mechanical aid-are considered an important technological innovation, with possible relevance for the successful Out-of-Africa dispersal of our species. Conclusive evidence for the beginning of this technology, however, is lacking from the early Late Pleistocene (ca. 130 to 70 thousand years ago; ka). Given the extremely limited applicability of relatively robust methods for validating stone-tipped projectile use, such as through fracture propagation velocity, converging lines of circumstantial evidence remain the best way to examine early complex projectiles. We assess here suggestions for an early Late Pleistocene origin of complex projectiles in Africa. Results from both previous and present independent approaches suggest a trajectory in which complex projectiles were likely adopted during the early Late Pleistocene in eastern Africa. At Aduma (Middle Awash, Ethiopia), morphometric, hafting, and impact damage patterns in several lithic point assemblages suggest a shift from simple spear technologies (thrusting and/or hand-cast) to complex projectiles. Broadly dated to 80-100 ka, lithic points from later phases of the Aduma succession represent a particularly strong candidate for projectile armatures most comparable to ethnographically known spearthrower darts, lending support for previous suggestions and warranting further investigations
