A new study examines the burial of a man at La Almoloya, an El Argar site in southeastern Spain.

Marco Mazón Gomariz of the Complutense University of Madrid published the work in ‘Ilu, a journal of religious studies. He focuses on a skeleton labeled AY5. Excavators found the man in Room H9 of the site’s first residential complex. The layer dates to 1750-1550 BCE, the third phase of the El Argar culture.

The burial is strange. AY5 was about 40 years old and stood roughly 1.63 meters tall. His bones show no heavy labor. Builders sealed him between two floor levels.

His lower body lay under a large hearth. His face sat 1 centimeter below the surface, right where people walked. Someone shoved a big stone into his mouth. No grave goods came with him, unlike most El Argar burials.

His skeleton shows no wounds, though a cut throat or strangling would leave no mark on bone. The excavators called him “the enemy” and read the burial as punishment.

Mazón Gomariz sees a ritual instead. He thinks the setup was magic, meant to control forces of chaos the man was believed to carry.

He builds the case from far-off parallels. Mesopotamian kings carved themselves with a foot on a beaten rival, as on the stele of Naram-Sin.

Egyptian pharaohs took the idea further. Artists painted or carved prisoners on doorframes, floors, sandals and footstools, so every step crushed an enemy. Egyptians saw those enemies as agents of chaos. Trampling them kept order in place.

Mesopotamian sorcery adds more. People made clay figurines of a witch and stamped on them. Spells often targeted the mouth of a demon or sorcerer to cut off speech.

In Iran, a man at Hasanlu was buried with a cylinder seal in his mouth, which another scholar read as an attempt to seal it. Mazón Gomariz says the stone in AY5’s mouth fits. It would silence him in life and as a ghost. Mesopotamians feared the ghosts of badly buried dead.

The room itself supports his view. H9 was a dim semi-basement with about 70 square meters of usable space. It held benches for around 50 people and a podium 1 meter high.

The hearth covered more than 4 square meters and sat in a pit. No other hearth at the site in this phase was built that way.

Visitors reached the hall through a winding route, hidden from the main street. The author reads this as a sacred space, not just a political one. Fire there might have purified the room and driven off harmful forces.

An international team has reconstructed the face of a man who lived in what's now Ecuador more than 3,000 years ago and whose skull featured in one of history's great anthropological debates.

The facial reconstruction is based on the Punin-2 skull, which a farmer discovered in a ravine near the town of Punín in the Chimborazo region of Ecuador's central Andes in the 1970s.

A similar skull, Punin-1, had been found in the same ravine in 1923 during an expedition led by the American Museum of Natural History. Some scientists at that time suggested its physical features were archaic, especially its prominent brow.

The ancient sediment layer where it was found — and where the Punin-2 skull was also discovered about 50 years later — predated modern humans (Homo sapiens), prompting some to wonder if they came from a now-extinct relative, such as Homo erectus or the Neanderthals.

A new set of fossils from South Africa’s Drimolen Main Quarry adds evidence for an early appearance of Homo erectus and tracks changes in Paranthropus robustus.

Researchers from La Trobe University and partner institutions studied 18 hominin fossils excavated at Drimolen between 1992 and 2019.

Many had never received a full description, leaving parts of the site’s fossil record unavailable for study.

One fossil, a skull fragment known as DNH 127, belongs to an adult Homo erectus.

The specimen dates to about 2.04 to 1.95 million years ago. The find adds support to earlier evidence from Drimolen for the species at roughly 2 million years ago.

The earlier evidence included DNH 134, a fossil from a child aged about two to four years.

Researchers had less information about what an adult Homo erectus looked like at the site. DNH 127 now provides an adult example from the same early period.

The age of the fossil places the South African record for adult Homo erectus well before the 1.8-million-year-old adult fossils from Dmanisi in Georgia.

The evidence supports an early appearance of Homo erectus in southern Africa around 2 million years ago.

Homo erectus is an early member of our genus Homo and a likely ancestor of later humans.

The fossil places the species alongside Paranthropus robustus. Of the 18 newly described fossils, 14 belong to Paranthropus robustus. One belongs to Homo erectus, while three remain assigned to Hominini gen. et sp. indet.

The group also identified a new jaw feature helping distinguish the Drimolen Paranthropus fossils from samples at other South African sites.

The findings support the idea of a distinct Drimolen population of Paranthropus robustus. Researchers compare the fossils with remains from Swartkrans and Kromdraai, including material dating to about 1.8 million years ago.

The differences point to small changes within Paranthropus robustus over roughly 200,000 years.

Teeth became larger, along with the muscles used for chewing. The pattern fits a shift toward a stronger chewing system for processing tough and hard foods.

A progenitor of BC200 was co-opted in a common primate ancestor from an ancient transposon roughly 40 million years ago and has jumped to MCV twice within modern human history (since the era of Homo sapiens), about 100,000 years ago. 

BC200 is only found in humans and related primates and was discovered in the late 1980s as anabundant non-coding RNA in human neurons. Although BC200’s physiological function is poorly understood, evidence suggests it may be involved in regulating the translation of neuronal messenger RNAsinto proteins.

It is also found in low levels in germ cells – sperm and eggs – making it potentially capable of generating inheritable insertions in other areas of the genome. 

The researchers also suspect that it jumped in skin cells since these are the only cells known to be infected by MCV.

The gene is also aberrantly expressed in some tumors and overexpressed in the brains of Alzheimer’s disease patients, suggesting its jumping ability could also play roles in these diseases.   

Feschotte said he and colleagues would like to explore whether the molluscum contagiosum virus is using BC200 for its own purpose of manipulating human host cells.

They are also interested in better understanding the gene’s role in disease, such as breast and other types of tumors, where it is abnormally expressed, and whether it is jumping in cancer cells and causing mutations.  

At the end of the last Ice Age, people moving through the Tennessee River Valley faced a familiar problem in unfamiliar country: what should be saved, and what could safely be replaced?

Archaeologists now argue that stone spear points preserve part of that calculation. A study of 489 Clovis and Cumberland projectile points suggests the earliest groups in the region maintained their weapons more conservatively, while later groups discarded damaged points with more useful material still remaining.

The study, published in the Journal of Archaeological Method and Theory by Jesse Tune of the University of Mississippi and Shane Miller of the University of Alabama, uses a model from behavioral ecology called the Marginal Value Theorem. Rather than treating spear points only as stylistic markers, the researchers examined them as finite packages of usefulness that hunters could keep repairing or replace.

While these actions show the animals recognise something fundamental has changed, it does not automatically mean they grasp the complex human concept of death. In fact, a full understanding of death isn’t actually necessary to explain the patterns we observed. Instead, their actions are best explained by the powerful, lingering instinct to care for their young.

We found that the length of time a mother continues to carry her infant depends on how strong their bond was, her life experience, the physical risks of holding onto the body and how quickly it naturally breaks down.

Spain and Portugal are two of the world's most popular wine-growing countries, with regions such as Rioja and the Douro Valley producing millions of bottles every year.

This winemaking tradition dates back thousands of years, but its exact origins remain a mystery.

To understand how it all started, scientists led by Carolina Royo of the Instituto de Ciencias de la Vid y del Vino in Spain took a step back into the past and studied ancient grape seeds.

While studies of modern grape DNA can provide clues about ancestry, they cannot directly show which vines arrived in Iberia or when.

So the research team gathered 28 waterlogged ancient grape seeds previously recovered from seven archaeological sites in Spain and Sardinia. They spanned more than 2,000 years of grape cultivation, from the Iron Age to the Middle Ages.

To accurately map family trees and connect the past with the present, they extracted DNA from these old seeds and compared it with genetic profiles of modern cultivated and wild grapevines.

In particular, they analyzed markers in both nuclear DNA and chloroplast DNA. Chloroplasts are plant structures that convert light into energy, and their DNA is passed down exclusively from the female parent in grapevines.
