Cut marks on the foot bone from El Mirador cave, Spain
iphes-cerca
The discovery of human remains in caves in northern Spain indicates that Neolithic people may have resorted to cannibalism after battles.
Francesc Marginedas from the Catalan Institute of Human Paleoecology and Social Evolution (IPHES) in Tarragona, along with his team, examined fragments from 650 human remains found in El Mirador cave on Mount Atapuerca. These remains date back approximately 5,700 years and belong to 11 individuals.
All examined bones displayed evidence that these individuals had been consumed by other humans. Some exhibited chop markings made by a stone tool, while others showed translucent portions with gently rounded edges. Some of the long bones were fractured open with stones to access the bone marrow, and smaller bones like metatarsals and ribs had clear human bite marks.
This research supports the notion that cannibalistic practices were more prevalent in human history than previously believed.
El Mirador marks at least the fifth significant site in Spain with notable evidence of cannibalism during the Neolithic era, a shift period from foraging to agriculture, according to Margida. “There’s a growing understanding that such behavior was more frequent than we anticipated.”
The motives behind these cannibalistic acts remain unclear. Some archaeological sites show skull cups indicating a ritualistic aspect to cannibalism, while others hint at survival strategies during dire circumstances.
However, Marsidas and his team propose that the findings at El Mirador suggest these acts were linked to warfare. There was a significant amount of animal remains, and no signs of nutritional stress among the humans involved, indicating this early agricultural community was not struggling with food scarcity. Their findings offer no indication of ritualistic behavior, as human bones were found alongside animal remains.
The ages of the individuals ranged from under seven to over fifty, implying that an entire family unit may have been lost to conflict. Radiocarbon dating indicated that all 11 individuals were killed and consumed within a few days.
This evidence reflects patterns of conflict and cannibalism, which have also been noted at two other Neolithic sites: the Von Bregore Caves in France and Helxheim in Germany. This period appears marked by instability and violence due to community clashes with neighboring groups and newcomers.
While Margida and his colleagues are uncertain about the reasons behind these cannibalistic practices, historical ethnographic studies suggest that such acts during warfare can serve as a method of “ultimate exclusion.” “We believe that one group attacking and consuming another serves as a humiliating statement,” states Merseydus.
“The thoroughness of the body’s treatment and consumption is remarkable.” Paul Pettitt from Durham University, UK, comments, “The aggressive nature shown in these artifacts, regardless of whether the consumed were relatives or adversaries, mirrors a dehumanization process during consumption.”
Sylvia Bello from the Museum of Natural History in London concurs that this evidence of death likely ties back to conflicts but remains skeptical about the notion of consumption as humiliation. She suggests that cannibalism may stem from aggression and animosity rather than ritualized farewell practices, implying a more complex interpretation. “It could carry ritual significance, even amid warfare,” she asserts.
Neanderthals, Ancient Humans, and Cave Art in France
Join new scientist Kate Douglas on an enthralling exploration of the key Neanderthal and Upper Paleolithic sites in southern France, spanning from Bordeaux to Montpellier.
New research has revealed that during the early Bronze Age in England, at least 37 people may have been “systematically dismembered” and eaten in the aftermath of “extremely violent” attacks.
The study, published in the journal ancient, revealed that more than 3,000 bones were excavated from a 50-foot hole at Charterhouse Warren in southwest England.
The bones, which were first discovered in the 1970s by cave explorers, showed an “abundance of cut marks,” prompting researchers to conduct further analysis.
Lead author Rick Schulting, a professor of scientific and prehistoric archeology at the University of Oxford, described the violence inflicted on the bodies as exceptional, with victims being killed with blows to the head, systematically dismembered, skinned, and crushed.
The study suggests that this extreme violence likely occurred in a single event between 2210 BC and 2010 BC, making it a unique example of violence in early Bronze Age Britain.

This act of violence was likely not isolated and may have sparked a cycle of revenge within and between communities in the Early Bronze Age, according to Mr. Schulting.
The motives behind such attacks are difficult to determine, but the study suggests that tensions may have escalated from accusations of theft and witchcraft, leading to an uncontrollable spiral of violence.
Victims may have been eaten to dehumanize and treat them like animals, involving a large number of aggressors based on the number of victims and the dismemberment process, the study noted.
The bones were found alongside animal fossils, indicating early evidence of slaughter, which the researchers believe was driven by hunger as the attackers had access to plenty of food.
Cerebellum of a person suffering from kuru disease

Genetic research in a very remote community in Papua New Guinea has revealed new insights into a brain disease that is spread when people eat dead relatives and has killed thousands of people over two decades.
Dotted with mountains, gorges, and fast-flowing rivers, Papua New Guinea’s Eastern Highlands province is extremely isolated from the rest of the world, and it wasn’t until the beginning of the 20th century that outsiders realized that about 1 million people lived there.
Some tribes known as the Fore practiced a form of cannibalism called “funeral feasts,” in which they consumed the bodies of their deceased relatives as part of their funeral rites. This could mean they ingested an abnormally folded protein called a prion, which can cause a fatal neurodegenerative condition called kuru associated with Creutzfeldt-Jakob disease (CJD). However, the local people believed that the Kuru phenomenon was caused by witchcraft. At least 2,700 Kuru deaths have been recorded in the eastern highlands.
Simon Mead Researchers at University College London examined the genomes of 943 people representing 68 villages and 21 language groups in the region. Although this region of Papua New Guinea covers just over 11,000 square kilometers, smaller than Jamaica, researchers say the different groups are as genetically different as the peoples of Finland and Spain, some 3,000 kilometers apart.
The study found that not everyone who attended the funeral died from the disease. Mead and his colleagues say it appears communities were beginning to develop a resistance to kuru, which led to tremors, loss of coordination, and, ultimately, death.
The study found that some of the elderly women who survived the feast had mutations in the gene encoding the prion protein, which likely conferred resistance to kuru disease.
By the 1950s, funeral feasts had become illegal, and the kuru epidemic began to subside, but visitors say that the number of women in some villages had dwindled because so many women had died from kuru. It pointed out. Mead said women and children are most susceptible to the disease, likely because they ate the brains of deceased relatives.
However, genetic evidence shows that despite fears of the disease, there was a large influx of women into Fora tribal areas, particularly in areas where the highest levels of kuru were present.
“We believe it is likely that the sexual prejudice caused by Kuru caused single men in Kuru-affected communities to look further afield for wives than usual because they were unable to find potential wives locally. “We will,” Meade said.
He said the team wants to understand what factors confer resistance to prion diseases such as CJD, which caused a severe epidemic in the UK in the 1990s.
“[Our work sets] “This is a site to detect genetic factors that may have helped the Fore people resist kuru,” Mead said. “Such resistance genes may suggest therapeutic targets.”
Ira Debson Researchers from the Garvan Institute of Medical Research in Sydney, Australia, say the study provides new insight into the “rich and unique cultural, linguistic and genomic diversity” of the Eastern Highlands region.
“This is a demonstration of how genomics can be used to look almost back in time, reading the genetic signature of past epidemics and understanding how they have shaped today’s populations. It helps.”

Cutting, biting, slashing, and cannibalism are not words that we naturally associate with love. But there is beauty and splendor in the dark side of animal mating, too.
This article takes a closer look at eight of the strangest courtship behaviors in the animal kingdom.
Some male anglerfish often attach themselves to passing females, reducing them to little more than brainless sperm sacs. This is called “parabiosis,” where two organisms combine to develop a shared physiological system. Monkfish are the only known example of symbiotic symbiosis in nature.
Anglerfish develop symbiotic relationships in response to the vastness of the deep sea, where encounters between the sexes are rare and rare. A male bites the first female he encounters because it’s a safer choice than gambling with another female who may never arrive.
Biologists to investigate how anglerfish achieve symbiosis Dr. Thomas Boehm Researchers at the Max Planck Institute for Immunobiology and Epigenetics in Germany tested the DNA of 31 specimens from 10 species of monkfish.
They discovered that the monkfish species, which are fused male and female, lack important immune system genes. Somehow they are compromising the immune system to allow parabiosis without suffering any negative effects.
Understanding how anglerfish manage this trick could facilitate future blood transfusions and organ transplants and have important implications for medicine.
Snakes have two penises instead of just one. These organs, known as hemipenes, allow male snakes to mate with snakes from various directions. This is especially useful for red-sided garter snakes, which form chaotic “mating balls” during mating season in which males outnumber females 100 to 1.
This situation occurs because male snakes wake up from hibernation before females, causing a temporary imbalance in the sex ratio.
To increase the probability of mating success, the hemipenes of many reptile species have evolved complex spines that lock into place during copulation. In red-sided garter snakes, the hemipenis has a large spine that is inserted into the female during copulation.
This finding suggests that by contracting the genital opening and vagina, females may be able to forcefully reject male advances and thwart an unworthy partner’s chances of success.
Earlier this year, scientists discovered a type of nudibranch (Siphopterone Maxig) It stabs the partner directly in the center of the head with poisonous spurs, in the throes of love.
This spur (attached to the penis), called a penile stylet, injects a complex cocktail of hormones directly into the lover’s brain, increasing the odds of a successful copulation.
This is just one of the many reproductive oddities that nudibranchs have evolved. Some nudibranchs even “kiss” their bodies mouth-to-mouth before transferring their sperm. After mating, sea slugs can also “cuddle” by wrapping their colorful bodies around each other.
“Maybe ‘hugging’ is akin to protecting your spouse,” he says. Cheyenne Tatean experienced sea slug observer at the University of Massachusetts Amherst.
“The threat to their reproductive success is that their sperm gets digested by their partner before it can be used for fertilization. And ‘hugging’ gives sperm a chance to travel deeper within their partner’s reproductive tract. You can get it. ”
Most people think that sea slugs, like many invertebrates, are primitive lower orders of bony animals with large brains. Their rich and duplicitous sex lives suggest otherwise.
The case of male spiders is complicated. To prepare for sex, they must first ejaculate onto a small web and then collect the semen in a pair of syringe-like appendages near their mouth known as palps.
Locked and loaded, the male spider must approach the female and insert its antennae into the female’s reproductive passageway, being careful not to activate the predatory kill reflex. The female’s reproductive tract happens to be just a few millimeters from the venomous fangs.
To limit the chance of being eaten, male spiders have evolved complex dances to clearly communicate their sexual intentions.
Some offer gifts to the female to keep her entertained while the sperm transfer takes place. But male redback spiders go one step further: During mating, the male somersaults balletically into the female’s jaw, encouraging her to bite.
During courtship, some species of snails periodically fire chemical-tipped arrows at each other, like the garden snail pictured here.
And since snails have both female and male reproductive organs, these arrows (or “love darts”) often fly in both directions.
“The purpose of the love dart is not to kill the mate, but to introduce bioactive substances that affect the mate’s reproductive process,” states Dr. Joris M. Corne of the Amsterdam Institute for Life and Environmental Research.
The substances contained in love darts contain a rich cocktail of special compounds (known as allomones) that prevent sperm from being lost within the reproductive tract of a potential mate if mating takes place.
Each species of snail has its own unique shape. Some love darts are curved like a harpoon. Some have thorns. Some have diamond-shaped tips, like decorated spears.
Can misfires cause fatalities? “I’ve occasionally seen darts go straight into the recipient’s head, and the recipient survived.” says Joris M. Corne.
“Cannibalism has its advantages,” says Nathan Burke, a postdoctoral researcher at the University of Hamburg, who studies the mating strategies of praying mantises.
“It can lead to improved growth, condition and reproduction in cannibals. What makes many praying mantises and spiders different from other cannibals is that they also cannibalize in mating situations, usually eating the male. That means it’s only female.”
Burke is particularly interested in the wrestling matches that some praying mantis species engage in before mating. Wrestling matches involve violent grappling and violent contests between males and females who scrape their paws together.
If the female wins these struggles, the male will almost certainly be eaten. However, if the male wins, there is a good chance of mating.
Why sexual cannibalism is so rare among insects remains a subject of debate.
“The thing about praying mantises is that they are mostly sit-and-wait predators. They don’t move around looking for food, they patiently wait for food to come to them,” says Burke.
“This sit-and-wait lifestyle may be a pre-adaptation for sexual cannibalism.”
This may explain why cannibalism occurs in other sit-and-wait predators such as spiders.
A seed beetle’s penis, which has hundreds of sharp spines whose purpose is to scratch and tear the female’s reproductive organs, makes no sense at all.
After all, how does a penis gene that damages a woman’s reproductive tract spread throughout a population?
A female stag beetle that mated with a male with long spines produced sons with the same long spines. However, their daughters also appeared to have inherited some valuable traits.
On average, they were larger and produced more eggs during their lifetime.

Archaeologists have discovered the remains of at least six people at Gough's Cave in the Cheddar Valley in southwest England. Many of the bones were intentionally broken, and the fragments are covered in cut marks, the result of people using stone tools to separate the bones and remove the flesh.Additionally, 42 percent of bone fragments traces of human teeth. There is little doubt that the people who lived in this cave 14,700 years ago practiced cannibalism.
Today, cannibalism is considered taboo in many societies. We think that's an anomaly, as evidenced by films like . texas chainsaw massacre. We associate it with zombies, psychopaths, and serial killers like the fictional Hannibal Lecter. There are very few positive stories about cannibals. But despite our preconceptions, evidence is accumulating that cannibalism was a common human behavior, so perhaps it's time to reconsider.
Our ancestors have been eating each other for over a million years. In fact, it seems that about one-fifth of society has practiced cannibalism since ancient times. While some of this cannibalism may have been done simply to survive, in many cases the reasons appear to be more complex. For example, in places like Gough's Cave, eating the bodies of the dead appears to have been part of the funerary ritual. Some archaeologists say cannibalism may be a way to show respect and love for the dead, rather than a horrific insult to nature.
Stories of cannibals can be found throughout human history.At Homer's Odyssey,…
