Prints of the employment of stone fragments and others, to cut, to scratch, to line and to eat meat coming from the interior of goat and cow bones, would be evidence that human but early ancestors (homínids), used tools for but of 3.2 million years (data from volcanic rocks near to Dikika, the region where previously were found remains of Australopithecus afarensis, direct ancestor of Homo genus), one that was thought was vegetarian. Until recently the tools but old came from Gona, Ethiopia (2.5 million years ago). According to Zeresenay Alemseged (California Academy of Sciences), the discoveries make think that the employment of tools was not exclusive of Homo genus or species related to it, since so much A. afarensis and Homo used tools to eat meat. Alemseged and Shannon McPherron (Max Planck Institute of Evolutionary Anthropology in Leipzig), look for evidences to know if it was A. afarensis or another species that monopolized the employment of stone tools.
Huellas del empleo de fragmentos de piedra y otros para cortar, raer, rayar y comer carne procedente del interior de huesos de cabra y vaca, serian evidencia de que nuestros ancestros humanos mas tempranos (homínidos), usaron herramientas desde hace mas de 3.2 millones de años (datación de rocas volcánicas cercanas a Dikika, la región donde anteriormente fueron encontrados restos de Australopithecus afarensis, ancestro directo del genero Homo, del que se pensaba era vegetariano. Hasta hace poco las herramientas mas antiguas provenian de Gona, Etiopia (2.5 millones de años). Según Zeresenay Alemseged (California Academy of Sciences), los hallazgos hacen pensar que el empleo de herramientas no fue exclusivo del genero Homo o species relacionadas a el, ya que tanto A. afarensis y Homo empleaban herramientas para comer carne. Alemseged and Shannon McPherron (Max Planck Institute of Evolutionary Anthropology in Leipzig), buscan evidencias para saber si fue A. afarensis u otra especie la que monopolizo el empleo de cortes con piedras.
