Stone tools preserve more than technology. They also preserve evidence of learning.
A new study of the Middle Palaeolithic open-air site of Givat Rabi East (Israel) examines Levallois technology through cores, flakes and reduction sequences to explore how knapping skills were transmitted across generations. The researchers identified systematic raw material management, deliberate reuse of cores and distinctive "shared cores" that bear evidence of both expert and novice knappers working on the same artefacts. These findings suggest that Levallois technology was not simply copied but taught through apprenticeship, where knowledge was passed from experienced individuals to learners over time.
Despite abundant high-quality local flint, the inhabitants carefully conserved raw material by retaining cortical surfaces, rejuvenating cores and repeatedly reworking stone tools. Such behaviour reflects deliberate technological planning rather than resource scarcity, revealing that social learning and cultural transmission were central to maintaining Levallois traditions in the Levant. The study adds a valuable behavioural dimension to Middle Palaeolithic archaeology, demonstrating that prehistoric stone tools can illuminate not only technological innovation but also the teaching and learning practices that sustained human cultural evolution.

When did the first modern humans reach Sahul, the ancient landmass connecting Australia, New Guinea and Tasmania?
A new Science Advances study analysed 2,456 mitochondrial genomes, together with Y-chromosome, genome-wide, archaeological and palaeoclimatic evidence, to reassess one of prehistory's longest-running debates. The results strongly support the "long chronology", indicating that modern humans settled Sahul around 60,000 years ago, rather than the later estimate of 47–51 thousand years ago. The research also suggests that these pioneering populations entered Sahul through at least two distinct migration routes, one via northern Wallacea into New Guinea and another through southern Wallacea into Australia.
Beyond refining the timeline, the study highlights the remarkable maritime capabilities of early Homo sapiens. Reaching Sahul required repeated sea crossings long before the development of agriculture, demonstrating advanced planning, navigation and adaptation to unfamiliar island landscapes. By integrating genetics with archaeology, this research provides one of the strongest multidisciplinary cases yet for an early human expansion into the Australasian continent, offering fresh insights into one of humanity's greatest prehistoric migrations.

Can artificial intelligence help archaeologists rediscover how people played games nearly two thousand years ago?
A study published in Antiquity investigates a uniquely engraved limestone object from the Roman town of Coriovallum (modern Heerlen, Netherlands), whose unusual pattern did not match any known ancient board game. Rather than relying solely on visual comparison, researchers combined use-wear analysis, 3D surface modelling, and AI-driven gameplay simulations using the Ludii game system to test hundreds of possible rule combinations.
The simulations consistently showed that blocking games, where one player attempts to trap the opponent's pieces, best reproduced the wear patterns preserved on the stone. This suggests that the object was most likely a Roman game board for a previously undocumented game, extending the known history of this family of board games by many centuries. More importantly, the study demonstrates how artificial intelligence can move beyond identifying artefacts to reconstructing ancient human behaviour, offering a powerful new approach for exploring archaeological questions that have long remained unanswered.

What happened after the fall of the Western Roman Empire? Was it a simple replacement of one population by another, or the emergence of an entirely new society?
A new Science study analysed 314 ancient genomes from Roman and post-Roman cemeteries across Pannonia (modern western Hungary), integrating ancient DNA, isotopic evidence, and archaeology to reconstruct community formation at an unprecedented resolution. The researchers identified a substantial influx of Northern European ancestry around the sixth century CE, consistent with the expansion of the Langobards. However, the incoming groups did not replace the local population. Instead, they mixed with existing Roman communities, creating genetically and culturally diverse societies.
Beyond migration, the study reveals that early Langobard communities developed distinct social hierarchies. Large biologically related kin groups occupied privileged positions, with archaeological evidence suggesting inherited status, while neighbouring communities displayed markedly different social organisations despite sharing similar material culture. Together, these findings demonstrate that the emergence of the Langobard polity was driven by dynamic interactions between migration, local continuity, and evolving social networks, rather than by simple conquest or population replacement.

For decades, geometric reasoning has been considered a defining hallmark of human intelligence. A new study challenges that assumption.
Using behavioural experiments with monkeys, preschool children, and adults, researchers found that humans and monkeys rely on remarkably similar high-level geometric representations. Rather than revealing a uniquely human symbolic system, the results support an evolutionary continuum in which geometric intuition is shared across primates and becomes progressively refined through development and experience.
The study further demonstrates that rotation-invariant shape recognition, the ability to recognise a shape regardless of its orientation, plays a central role in geometric reasoning. Once this factor is considered, the apparent gap between humans and monkeys largely disappears. Instead of a sharp evolutionary divide, the findings point to a gradual amplification of shared cognitive mechanisms.
These findings reshape our understanding of the evolutionary origins of abstract thought, suggesting that the foundations of geometry emerged long before our species and were inherited from a common primate ancestry. Human mathematical cognition may therefore represent an expansion of ancient cognitive abilities rather than an entirely unique evolutionary innovation.

Violence, survival, and care have shaped human history far longer than written records.
A new multidisciplinary study of the Middle Palaeolithic individual Qafzeh 25 from Israel re-examined the fossil using high-resolution micro-CT, revealing a previously overlooked sharp-force injury to the left mandible and premolar. Evidence of bone remodelling demonstrates that the individual survived the wound, making it one of the earliest documented cases of healed sharp-force trauma in the archaeological record.
Beyond trauma, the researchers identified a hidden dental carious lesion and reassessed the burial context, finding strong taphonomic evidence that Qafzeh 25 was intentionally interred. Together, these discoveries provide a rare glimpse into the lives of early Homo sapiens, highlighting resilience after serious injury, oral health, and the emergence of deliberate funerary practices during the Middle Palaeolithic.
Studies like this remind us that fossil bones preserve more than anatomy. They record episodes of conflict, recovery, caregiving, and mortuary behaviour, offering an increasingly detailed picture of the social complexity of our early ancestors.

Even today, science continues to discover large mammals hidden within Earth's remaining wilderness.
Researchers have described Colobus congoensis, commonly known as Likweli, as a new species of black-and-white colobus monkey from Lomami National Park, Democratic Republic of Congo. Integrating field observations, morphology, genetics, and vocalisation analyses, the study demonstrates that Likweli is a distinct species and the closest known relative of the black colobus (Colobus satanas), despite being separated by more than 1,200 km.
With a known distribution of only about 1,700 km², Likweli inhabits mature closed-canopy forests and already faces threats from hunting and habitat loss. The authors therefore recommend an initial Endangered conservation status, highlighting the critical role of Lomami National Park in safeguarding one of Africa's newest primate species.
The discovery reminds us that biodiversity is still incompletely known. Protecting the world's remaining forests is not only about preserving species we know, but also those science is only beginning to uncover.

For decades, Pakistan's loess deposits were believed to be confined mainly to its northern highlands. This new study overturns that view.
Through extensive field investigations, grain-size analysis, magnetic mineralogy, and geochemical investigations, researchers identified widespread aeolian loess deposits across the Indus Plain, revealing an overlooked archive of South Asian environmental history. The study shows that loess deposition in northern Pakistan began at least 300,000 years ago, while deposits across the Indus Plain accumulated mainly during Marine Isotope Stage 3 (60,000-25,000 years ago).
The findings also demonstrate strong regional differences in grain size, paleosol development, magnetic properties, and weathering, reflecting the combined influence of the Indian Summer Monsoon, Thar Desert dust, regional topography, and hydrology. These newly identified sequences provide an important framework for reconstructing Quaternary climate variability and understanding dust transport across South Asia.
Sometimes, the most valuable climate archives are not hidden beneath ice sheets or deep oceans, but preserved as layers of wind-blown dust waiting to be recognised.

What happens after a civilization declines?
A new ancient DNA study from the Bury megalithic cemetery in the Paris Basin sequenced 132 ancient genomes, revealing that the people buried before and after the Neolithic decline were genetically distinct. Rather than simple cultural continuity, the cemetery records a substantial population turnover around 2900 BC, accompanied by shifts in ancestry, kinship patterns, and burial traditions. s41559-026-03027-z
The research also detected ancient pathogens, including Yersinia pestis (plague), alongside evidence of forest regeneration, suggesting a period of demographic contraction before new farming populations carrying southern Neolithic ancestry expanded into the region. The study provides one of the clearest genomic windows into how prehistoric Europe was reshaped before the arrival of Steppe-related populations and the Bell Beaker phenomenon. s41559-026-03027-z
Sometimes, the greatest archaeological discoveries are not the monuments themselves, but the people who quietly disappeared from history.
