Испанийн Атапуерка цогцолборын Гран Долина агуйгаас 850 мянган жилийн тэртээх Homo antecessor төрөл зүйлийн насанд хүрсэн хувь хүмүүсийн чулуужсан үлдэгдэл илэрлээ.
Каталоны Хүний палеоэкологи ба нийгмийн хувьслын хүрээлэнгийн (IPHES) судлаачид Гран Долина агуйгаас гавлын яс, нуруу, мөчдийн ясны хэлтэрхий болон шүд зэрэг хоёр гаруй олдворыг малтан илрүүлжээ. Эдгээр ясан дээр чулуун зэвсгээр хийсэн зүсэлтийн ул мөр байгаа нь тухайн үед амьдарч байсан Homo antecessor төрөл зүйлийнхэн өөрийн төрлийнхнийг хүнсэндээ хэрэглэдэг байсныг нотолж байна. Өмнөх судалгаагаар каннибализмын ул мөр зөвхөн хүүхэд, өсвөр насныхны яснаас илэрч байсан бол энэ удаагийн олдвор насанд хүрэгчид ч мөн адил өртөж байсныг харуулснаараа онцлог юм.
Судлаач Пальмира Саладьегийн тэмдэглэснээр, энэхүү олдвор нь каннибализм зөвхөн хүүхдүүдээр хязгаарлагдаагүй болохыг баталж байна. Одоогоор тус газраас илэрсэн нийт 13 хүний үлдэгдлийн тал орчим хувь нь насанд хүрэгчид байгаа нь тухайн популяцийн амьдралын хэв маягийг илүү өргөн хүрээнд судлах боломжийг олгож буй юм.
Малтлагын явцад чулуун зэвсэг болон гиена, зэрлэг адуу, хирс зэрэг амьтдын яснууд олдсон нь хүний ясан дээрх зүсэлттэй адил техникээр амьтдыг нядалдаг байсныг харуулж байна. Ясан дээрх хүний хазаж авсан ул мөр нь эдгээр бие махбодыг хүнсэндээ хэрэглэж байсны хамгийн найдвартай нотолгоо гэж эрдэмтэд үзэж байна. Одоо судлаачид энэхүү зан үйлийн шалтгаан болон тухайн бүлгийн нийгмийн зохион байгуулалтыг тодруулахаар үргэлжлүүлэн ажиллаж байна.

Cut marks suggestive of cannibalism have been discovered on the fossils of an ancient human relative in a cave in Spain, new research finds. But many of the bones from the species, known as Homo antecessor, were from adults — not just children, as previous discoveries had found — adding a new dimension to the cannibalism that was practiced in this area 850,000 years ago.
The two dozen bones and teeth were recently found in Gran Dolina cave, part of the Sierra de Atapuerca archaeological complex in northern Spain, according to a July 24 translated statement from the Catalan Institute of Human Paleoecology and Social Evolution (IPHES). Among the remains were fragments of a skull, spine, arm and leg bones, as well as three teeth from several members of the now-extinct H. antecessor, a relative of modern humans that lived in Europe between about 1.2 million and 770,000 years ago. Several of the bone fragments had cut marks from stone tools.
Over the past few decades, researchers have identified numerous cases of cannibalism at Gran Dolina, meaning H. antecessor is the oldest known human relative to eat its own group members for nutritional reasons. In a 2010 study, researchers noted that most of the evidence of cannibalism at Gran Dolina came from the bones of infants and juveniles, who would have been easier to capture and kill as the young, defenseless members of a rival group. But the newly excavated fossils have upended that assumption.
“The discovery of more adult individuals, some of whom also bear cut marks, demonstrates that cannibalism was not restricted to younger individuals,” Palmira Saladié, a biological anthropologist at the IPHES who coordinated the work, said in the statement.
The number of individuals found at Gran Dolina has now risen to at least 13, and about half of them are adults. “The increase in the number of individuals, and especially the addition of more adults, allows us to begin understanding this population from a much more complete perspective than ever before,” Andreu Ollé, an archaeologist at the IPHES, said in the statement.
Excavation at Gran Dolina has also brought to light an assemblage of stone tools made from flint, quartzite and sandstone, along with animal bones from hyenas, beavers, deer, horses and rhinoceroses, according to the statement.
Evidence of cannibalism at the site is extensive. Stone tools found in the cave are consistent with the cut marks on the human bones, and the animal bones have revealed butchering techniques that were also used on humans. Some of the human bones also had human bite marks, Saladié told Live Science in 2025, which is the “most reliable evidence that the bodies found at the site were indeed consumed.”
But while the practice of cannibalism at Gran Dolina has been confirmed, the reason for it is still unclear. Researchers hope the newly discovered adult bones may help them better understand the practice among H. antecessor groups.
“We have only just begun excavating this new area” at Gran Dolina, Marina Mosquera, an archaeologist at the IPHES, said in the statement, “and the first results already demonstrate its enormous scientific potential.”
Further analyses on the bones are now underway to explore questions about age-related differences in cannibalism, the number and length of cannibalistic episodes, and the social organization of H. antecessor, according to the statement.
