Over time, this population eventually gave rise to the majority of Homo sapiens ancestry, as well as to Neanderthals and Denisovans. We may find fossils that match their genetic legacy, or we may already have them but lack the tools to identify their role in our ancestry." This group shrank to a tiny size before slowly recovering.
Because most genomic research has focused on people of European ancestry, existing diagnostic tools and treatments often fail when applied to non-European populations. More Greenlanders now have European ancestry—on average, about 25%—which is influencing the frequency of certain genetic traits.

The researchers found no widespread East Asian ancestry among the European populations of the Carpathian Basin following the Huns' arrival. However, a small but distinct group of individuals, primarily from "eastern-type" burials, carried significant East Asian ancestry.
While Leobersdorf's population was predominantly of East Asian origin, Mödling's inhabitants carried European ancestry," said Ke Wang, one of the study’s lead geneticists. These people were obviously regarded as Avars, regardless of their ancestry." But ancient DNA analysis told a different story.
This ancient group shares ancestry with the 15,000-year-old foragers of Taforalt Cave in Morocco, associated with the Iberomaurusian culture. Neandertal DNA and the Origins of North African Ancestry Another striking discovery concerns the presence of Neandertal DNA in the Takarkori individuals.
A groundbreaking genetic study conducted by researchers at the RIKEN Center for Integrative Medical Sciences has uncovered new evidence that challenges the longstanding belief in a dual-origin model of Japanese ancestry. This study shows that their genetic legacy persists, with their ancestry decreasing as one moves westward across Japan.
What we’ve found, however, suggests a sophisticated society where maternal ancestry shaped group identity.” ” The avoidance of close inbreeding and the occurrence of marriages between distant family branches suggest that the Durotriges had a deep awareness of their ancestry.
Denisovan ancestry and population history of early East Asians. [link] Slon, V., The genome of the offspring of a Neanderthal mother and a Denisovan father. Nature , 561, 113–116. link] Massilani, D., Science , 370(6516), 579–583. link] 1 Tsutaya, T., Sawafuji, R., Taurozzi, A. Fagernäs, Z., Patramanis, I., Troché, G.,
The analysis revealed that Denisovans diverged from Neanderthals around 400,000 years ago, although the two groups share a common ancestry. Ongaro’s team has identified areas for further research, including more extensive genetic studies of understudied populations that may carry yet-undiscovered traces of Denisovan ancestry.
. “By connecting the dots between genetics, linguistics, and archaeology, we now recognize West Papua as the launching place of historical Papuan seafarers that now contribute up to 60% of modern Wallacean ancestry,” he said.
Credit: Incola / Wikimedia Commons Despite these external influences, the Picenes largely retained a genetic profile similar to other Iron Age Italic groups, emphasizing a shared ancestry that predated the Roman era. Green gradients show the hypothesized origins of individuals with diverse ancestries in the Central Italic IA.
Traditional ancestry reports often provide a static snapshot, indicating, for example, that an individual is "50% Irish." While informative, this perspective oversimplifies the intricate tapestry of human ancestry, which is more akin to a dynamic film than a still photograph. Credit: Science (2025).
“The ability to tie them may have been passed between cultures, or more likely through shared ancestry,” — Roope Kaaronen But cultural transmission can’t explain everything. In some cases, such as identical knots from South America and Russia, the likelihood of direct interaction is negligible.
Unraveling the Complex Origins of Homo sapiens At the core of understanding human evolution lies the question of human nature. Were early Homo sapiens inherently peaceful or aggressive?
Bridging Evolutionary Gaps in Asia Asia's evolutionary timeline during the Pleistocene is marked by a mosaic of hominin species, each contributing uniquely to human ancestry. .” The researchers hope that this systematic reclassification will enhance science communication by providing a more coherent picture of hominin diversity in Asia.
These genetic signatures match the so-called "Fournol cluster" of Gravettian ancestry, suggesting that a distinct population survived in this region through the Last Glacial Maximum. “These were the people whose range had contracted southward during the climatic crisis,” explains Gelabert.
Grey wolf genomic history reveals a dual ancestry of dogs." The wolves that became dogs may have chosen to live alongside us—not because we tamed them, but because they evolved to see us as their best chance for survival. Related Research For further reading on dog domestication and evolutionary modeling: Bergström, A.
Their morphological resemblance to grey wolves thus results from convergent evolution rather than shared ancestry ( Perri et al. Despite coexisting geographically during the Late Pleistocene, dire wolves show no genomic evidence of interbreeding with grey wolves or coyotes, indicating prolonged evolutionary isolation.
Analysis of the Neanderthal genome revealed that 1 to 4% of the genome in modern humans living outside Africa is derived from Neanderthals," the study notes. The reason for this remains an open question High-Altitude Adaptations and the Denisovan Connection Living at high altitudes presents unique physiological challenges.
For instance, a study focusing on prehistoric individuals from France and Germany revealed significant levels of hunter-gatherer ancestry in early farming communities, suggesting continuous contact and integration between these groups over centuries. Instead, there was a prolonged period of coexistence and genetic admixture.
Delving into Canine Ancestry In a seminal study published 2022 in the prestigious journal Nature 1 , scientists embarked on a quest to unlock the secrets of dog domestication using a novel approach: analyzing the DNA of ancient wolves. Grey wolf genomic history reveals a dual ancestry of dogs. Ollivier, M., Speidel, L., Westbury, M.
“Most non-Africans today carry 1-2% Neanderthal ancestry, underscoring the impact of these interactions on the settlement of regions outside Africa.” The Genomic Landscape of Neanderthal Ancestry in Present-Day Humans Authors : Sankararaman, S., Origins of Modern Human Ancestry Authors : Bergström, A.,
The findings offer clarity on how Japan’s dual genetic ancestry emerged, enriching the current understanding of ancient East Asian migration. Principal investigator Jun Ohashi, "East Asian-related and Northeast Asian-related ancestries account for over 80% of nuclear genomes of the modern Japanese population.”
By examining variations in Neanderthal ancestry across different times and locations, they estimated the timing and duration of interbreeding events.

A population of hybrid ancestry? While Qafzeh Cave is well known for its early Homo sapiens burials , Manot Cave and Quneitra contain archaeological deposits from multiple time periods This makes it difficult to attribute these engravings to a specific hominin species. Did Neanderthals create them? Early modern humans?
An attempt to depict the relatedness of nearly 250,000 people in the All of Us study has drawn criticism.All of Us Research Program Genomics Investigators, Nature (2024), [link] The Complexity of Human Ancestry Data The controversy surrounding the depiction of genetic diversity underscores the challenges inherent in describing human ancestry data.
While 21% of teachers in Hawai’i are Japanese, only 10% have Native Hawaiian ancestry. Everett Collection/Shutterstock At the same time, I also recognize that my privileged experience in Hawaiʻi was forged by settler culture , the effects of which still persist in the state educational system.
Both positions allow for the occasional interbreeding that has resulted in a little bit of Neanderthal being present in many of us, especially those of European and East Asian ancestry. However, there are many challenges to exploring this distant time.
” By comparing this genome with others, the researchers discovered that this Neanderthal had ancestry from a distinct lineage, indicating the presence of multiple isolated communities in Western Europe up until their extinction. The DNA was analyzed along with other known Neanderthal genomes to understand their shared history.”
Peyrégne confirmed that if any such "superarchaic" ancestry exists, it would be shared between Denisova 3 and Denisova 25. The Max Planck researchers plan to publish the new genome soon, offering further insights into this mysterious group.
The vermillion marks on our foreheads dispel assumptions about our ancestry, I draw stares as we stand next to aunty. Peace is lotuses set afloat on seafoam always at risk of drowning in scattered uncertainty. We are a motley crew: aunty, uncle, and two young women.
Despite the technical challenges posed by DNA degradation, the researchers successfully sequenced the genomes, revealing valuable information about the inhabitants' ancestry and genetic stability.
Modern Europeans, with diverse genetic ancestries, carry traits influenced by the hunter-gatherers, farmers, and pastoralists. A Global Perspective: Extending the Genomic Exploration Experts laud the study's innovative approach to understanding ancient humans by examining how ancestry influences modern traits. 1 Allentoft, M.
For now, the science is almost entirely based on data collected from people with European ancestry, which limits the conclusions that can be drawn from it, so researchers feel that they’ve at least temporarily sidestepped the issue.
