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.
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.
