The bone, belonging to a relative of Homo sapiens, showed nine unique cut marks. Amazingly, these marks were a perfect match for the damage caused by stone tools.
” There are various other examples of types from the human evolutionary tree taking in each other for nutrition, however this fossil recommends that our types family members were consuming each other to make it through even more into the past than we recognized.”
The butchered fossil may have belonged to Australopithecus anamensis, however researchers do not have sufficient info to inform for sure.
New research study from the Smithsonians National Museum of Natural History exposes a dark and interesting element of human evolution. Researchers have actually uncovered the oldest proof to date that our close evolutionary loved ones might have turned to cannibalism over 1.45 million years back. The findings, published in Scientific Reports, offer a chilling look into the habits of our ancient forefathers and challenge our understanding of their dietary habits.
” The info we have informs us that hominins were likely eating other hominins at least 1.45 million years earlier,” she stated.
A dark past
Identified to verify her hypothesis, Pobiner teamed up with Michael Pante of Colorado State University. By producing 3D scans of molds made from the bones cut marks, they compared them to a thorough database of tooth, butchery, and stomp marks.
The consistent orientation of the marks suggests that a stone tool-wielding hand might have made them successively, without altering grip or adjusting the angle of attack. These cut marks are virtually indistinguishable from those discovered on animal fossils processed for consumption, suggesting that this possible act of cannibalism might have been driven by nutritional needs rather than ritualistic practices.
While cannibalism is not uncommon amongst various types, this finding recommends that our evolutionary relatives participated in this habits for survival far earlier than previously recognized. It raises questions about the concept that cannibalism was entirely a recent development in our evolutionary history.
While the cut marks alone do not conclusively show that the leg and other body parts were consumed, it is the most likely circumstance. The place of the cut marks on the bone, where the calf muscle would have been connected, suggests an intentional effort to remove flesh.
Their analysis exposed that 9 of the eleven marks were indisputably the result of stone tool use. The remaining two marks seemed bite marks, potentially originating from a big cat, with a lion being the closest match. These bite marks could have originated from one of the 3 types of saber-tooth felines that wandered the landscape at that time.

At first, the researchers analyzed the fossilized tibia, or shin bone, seeking clues and signs of ancient predators. But instead of teeth or claw marks, they discovered evidence of butchery. Did these early hominins actually eat their own?
The fossil was at first found several years back and is now part of the collections of the National Museums of Kenyas Nairobi National Museum. At first, scientists reckoned the shin bone need to have come from Australopithecus boisei, but the identity of the specimen was later on ascribed to Homo erectus in 1990. However, today researchers still cant comprise their minds about which species the fossil comes from as there is not adequate info.
Cannibalism or something much more ominous?
However what about the big cat bite marks? The individual performing the butchery could have eliminated the majority of the meat from the leg bone before a huge feline scavenged the remains. Or perhaps a big cat might have eliminated a hominin before being frightened, allowing opportunistic hominins to declare the kill. The precise series of events remains an enigma, shrouded in predatory intrigue.
All in all, these findings paint a stark photo of our ancient relatives. Were reminded that the human household has actually always engaged in complex and intriguing behaviors, rather than being something unique to modern-day humans.
CORRECTION (29 June, 2023): The storys heading and some of the articles text have been upgraded to clarify that the findings merely recommend rather than definitely conclude that the fossil is proof of hominin cannibalism. Though it is likely that cannibalism was included, it is not certain. An earlier variation of this story may have deceived readers into believing this is well-defined direct proof of ancient cannibalism.
The findings appeared in the journal Scientific Reports.
The marks just listed below the skulls ideal cheekbone have been credited to both stone tools and contact with sharp-edged stone blocks. The lack of considerable muscle groups on the skull makes it uncertain whether these marks resulted from attempts at getting food. In comparison, this just recently explained shin bone is much less ambiguous.
Cannibalism, by definition, needs both parties to belong to the very same species. The option, which is possibly even wilder, is that different types within the hominin family might have engaged in interspecies usage.
This recent discovery is not the very first to ignite speculation about ancient cannibalism. In 1976, a skull discovered in South Africa sparked an argument over the earliest known circumstances of hominin butchering. However, conflicting interpretations and the skulls unpredictable age have prevented definitive conclusions.

Thanks for your feedback!
The marks just below the skulls best cheekbone have been attributed to both stone tools and contact with sharp-edged stone blocks.
The bone, belonging to a relative of Homo sapiens, displayed 9 distinct cut marks. The hominin tibia and amplified location showing cut marks. The remaining 2 marks appeared to be bite marks, possibly originating from a big cat, with a lion being the closest match. These bite marks might have come from one of the 3 types of saber-tooth felines that wandered the landscape at that time.
