Researchers believe they have found the other evidence ofhuman ancestorsbutchering and perchance eating each other , date back around 1.45 million days . The pearl of an ancient human metal money displayed chop shot marks that were incredibly similar to those created by stone putz , suggesting ancient population were even more brutal than previously thought .
“ The entropy we have tells us that hominins were probable eating other hominins at least 1.45 million years ago , ” author Briana Pobiner say in astatement .
“ There are numerous other model of species from the human evolutionary tree consuming each other for aliment , but this fossil suggests that our mintage ’ relatives were eating each other to survive further into the past tense than we recognized . ”

The study see a fossilised shin bone from the collection of the National Museums of Kenya ’s Nairobi National Museum , on which they were look for telling marks of predator . The researcher , from the Smithsonian ’s National Museum of Natural History , were originally hoping to learn more about the types of predators that were prey on ancient humans , but found something else entirely .
With a magnifying methamphetamine hydrochloride , Pobiner key what search like evidence of slaughterhouse rather of bite marks clothe the shin , suggesting that this human was chop up by a tool . To break , the team made a shape of the marks and enter them into a large database , before compare them to other marks of depredation or trample through a series of experimentation .
In total , nine out of the 11 mark search at were consistent with pit tools , while the other two were thought to be snack marks from a Leo the Lion - esque big cat , likely a saber - toothed computerized axial tomography . Taking a closer expression at where the creature crisscross were , they were around the country where the muscular tissue meet the bone in a ordered direction , as if someone was sat chopping the meat from the bone . grant to the researcher , it wait a lot like marks from humans being processed for consumption .
Of of course , it is out of the question to really tell whether they were deplete – they could have been chop up for presentation or inhumation , instead . However , it looks extremely likely that whoever owned that tibia met a sick end and may well have been eaten by other humans .
“ These deletion marks reckon very similar to what I ’ve regard on fauna fossils that were being processed for intake , ” Pobiner aver .
“ It seems most likely that the sum from this leg was eat and that it was eaten for aliment as opposed to for a ritual . ”
It is also not necessarilycannibalism , even if the human being was feed , as it is unclear exactly what species of hominin they were . For it to be classified as such , it would need to be proven that the eaten and feeder were the same specie , which is not potential at this time .
What it does prove , though , is that there continue to be some genuine gems hide in museum collection , still hold back to be found .
The study is published inScientific Reports .
