A new ancient DNA study has uncovered the 5,000-year population history of Xinjiang, China, revealing a complex mix of local northern Asian and western Steppe ancestry in Bronze Age populations. The study found that these early populations were broadly mixed with unique ancestral components from southern Siberia and Central Asia.
Researchers from China, Germany, France and Spain uncovered the lifestyle of humans living in East Asia 40,000 years ago. The study found evidence of ochre processing, miniature stone tools and bone tools, demonstrating technological innovations and cultural diversification.
Professor Wil Roebroeks receives the 2021 Gutenberg Research Award for his groundbreaking work on Neanderthals and early Eurasian hominins. The award acknowledges his interdisciplinary approach, international collaboration, and devotion to paleoanthropology.
Researchers discovered a 150-million-year-old dinosaur with evidence of an avian-style respiratory infection, providing insight into ancient diseases. The study suggests that sauropod dinosaurs may have been susceptible to fungal infections similar to aspergillosis.
A recent study challenges the idea that meat consumption drove major evolutionary changes in humans, suggesting instead that increased research attention may have skewed evidence. The research team analyzed data from nine sites across eastern Africa and found no sustained increase in carnivory after Homo erectus appeared.
The Omo I fossils, found in Ethiopia, have been dated to be at least 230,000 years old, pushing back the known emergence of Homo sapiens by tens of thousands of years. This reevaluation was made possible through advanced geochemical analysis and a new understanding of volcanic ash layers.
A 10,000-year-old female infant was buried with beads and pendants, indicating recognition of her as a full person in her society. The discovery provides insight into the early Mesolithic period and challenges previous assumptions about funerary practices during this time.
A study of Edo-era Japanese skeletons reveals a prevalence of periodontal disease similar to modern times, with distinct bacterial species. Researchers analyzed dental calculus from 12 human skeletons and compared their oral microbiomes to modern samples, shedding light on the evolution of the oral microbiome.
A new study reveals the oldest known punctate ivory pendant found in Eurasia, dating back 41,500 years. The pendant provides direct evidence of Homo sapiens' use of decorative motifs in Poland.
A new species of human ancestor, Homo bodoensis, has been named by an international team of researchers, providing clarity to the poorly understood Middle Pleistocene period in human evolution. The new classification resolves long-standing terminology issues and recognizes a direct human ancestor.
A study by Arizona State University researchers reveals that the coordination between facial growth and chewing muscle mechanics determines when adult molars emerge. The study found that human molars come in at a later age due to slow jaw growth and short faces, which creates a mechanically safe space for molar emergence.
A 16,000-25,000-year-old jawbone from Sulawesi provides conclusive evidence of Pleistocene-era humans in the region. The fossil exhibit unusual dental wear patterns, offering insights into the daily lives and dietary habits of early Homo sapiens.
Scientists have discovered two new species of spinosaurid dinosaurs on the Isle of Wight, providing significant insights into the UK's spinosaurid population. The newly found fossils, including Ceratosuchops and Riparovenator, measure around nine meters in length and suggest a diverse ecosystem with multiple predators.
A team of archaeologists led by Paola Villa has uncovered an unprecedented array of bone tools crafted from elephant bones at the Castel di Guido site in Italy, dating back to around 400,000 years ago. The discovery reveals a high level of cognitive intellect and technological sophistication among early humans during this period.
Researchers analyzed Neandertal and Denisovan genomes to identify blood groups, confirming their African origin and Eurasian dispersal. The study also found evidence of low genetic diversity and possible demographic fragility, shedding light on the disappearance of Neandertals.
A newly discovered sandgrouse fossil from six to nine million-year-old rocks in western China sheds light on the arid habitats near the edge of the Tibetan Plateau. The fossil, named Linxiavis inaquosus, provides key insights into the evolution of sandgrouse and their adaptation to dry environments.
Researchers confirm that two ancient hominin skeletons are from the same early species, Australopithecus sediba. The study provides new insights into the species' adaptations for bipedalism and tree-climbing.
The newly discovered Australopithecus sediba species is unique, sharing features with both Australopithecus africanus and early Homo species. Its fossils reveal a mix of bipedalism and arboreal adaptations, challenging traditional linear views of evolution.
The discovery of Bannykus and Xiyunykus sheds light on the evolution of alvarezsaurian dinosaurs' monodactyl hands. These ancient theropods display a major macroevolutionary shift from grasping hands to specialized, functionally monodactyl hands.
A new study revealed that ancient elephant relatives, such as Gomphotherium connexum and G. steinheimense, primarily ate soft foliage and grasses 17 million years ago. The team found phytoliths stuck to their teeth and analyzed wear patterns on fossil tooth surfaces to confirm these results.
Researchers have discovered a remarkable new species of marine reptile that lived during the Triassic Period. Atopodentatus unicus was an herbivore with a hammerhead-shaped jaw apparatus and used its teeth to filter-feed on plants from the ocean floor.
A newly discovered enantiornithine bird from the Early Cretaceous period in China provides the oldest unambiguous record of an avian gastric pellet. The fossilized remains include a fish-rich pellet, suggesting that some Early Cretaceous birds had evolved modern avian digestive features.
A team of scientists has uncovered over 1,500 hominin fossils in a cave complex in South Africa, representing the largest and most complete set found to date. The discovery adds a new branch to the human family tree, with the fossils suggesting that Homo naledi was deliberately depositing its dead in the cave.
Researchers found bones bearing unambiguous evidence of stone tool use, including cut marks made while carving meat off the bone. The discovery provides the first evidence that Lucy's species, Australopithecus afarensis, used stone tools and consumed meat, shifting the known timeframe of a game-changing behaviour for our ancestors.
The study reveals that the Liujiang brain shares morphological features with modern humans, including a round shape and enlarged frontal lobes. The virtual endocast also shows a high brain capacity, suggesting a Late Homo sapiens classification.
A 40,000-year-old human skeleton found in China suggests that modern humans may have migrated to the region via multiple routes rather than a single 'out of Africa' event. The discovery provides valuable insights into the emergence of modern humans in eastern Asia.
A 3-year-old Australopithecus afarensis girl, discovered in Ethiopia, provides a unique window into human infancy. The fossil offers clues about skull morphology, brain growth, locomotion, and height, shedding light on early human evolution.
Paleoanthropologist Geoffrey Clark questions the clear evidence for human 'replacement', suggesting that archaeological findings reveal a more complex mosaic pattern. He proposes an alternative cause for cultural and technological changes, linking them to population density and critical selection pressures.
