Neandertal genes shed light on unique aspects of the modern human brain
Jonathan KantrowitzatArchaeology News Report - 2 weeks ago
Modern human skulls have a unique 'globular' (round) shape. Our closest cousins, the long extinct Neandertals, had the elongated skulls that are typical of most primates. This striking shape difference is suspected to reflect evolutionary changes in the relative sizes of structures of the human brain, perhaps even in the ways that key brain areas are connected to each other. However, brain tissue doesn't itself fossilize, so the underlying biological explanation has remained elusive. An international research team, led by paleoanthropologist Philipp Gunz (MPI, Leipzig) and genetic... more »

Neanderthal healthcare practices crucial to survival
Jonathan KantrowitzatArchaeology News Report - 2 months ago
Research at the University of York has suggested that Neanderthals embraced healthcare practices, such as assisting in cases of serious injury and the challenges of childbirth. Healthcare practices in this period of human evolution have often been studied alongside complex cultural behaviour, mostly based around research into rituals and symbols associated with death. This new study, however, sets out, for the first time, that healthcare could have had a more strategic role in Neanderthal survival. Previous research at the University of York has already suggested that compassion ... more »
Neandertal mother, Denisovan father!
Jonathan KantrowitzatArchaeology News Report - 4 months ago
Together with their sister group the Neandertals, Denisovans are the closest extinct relatives of currently living humans. "We knew from previous studies that Neandertals and Denisovans must have occasionally had children together", says Viviane Slon, researcher at the MPI-EVA and one of three first authors of the study. "But I never thought we would be so lucky as to find an actual offspring of the two groups." The ancient individual is only represented by a single small bone fragment. "The fragment is part of a long bone, and we can estimate that this individual was at least 13 y... more »
Neandertal fire-making technology inferred from microwear analysis
Jonathan KantrowitzatArchaeology News Report - 5 months ago
*Scientific Reports *complete article Fire use appears to have been relatively common among Neandertals in the Middle Palaeolithic. However, the means by which Neandertals procured their fire—either through the collection of natural fire, or by producing it themselves using tools—is still a matter of debate. We present here the first direct artefactual evidence for regular, systematic fire production by Neandertals. From archaeological layers attributed to late Mousterian industries at multiple sites throughout France, primarily to the Mousterian of Acheulean Tradition (MTA) tech... more »

Compassion helped Neanderthals to survive
Jonathan KantrowitzatArchaeology News Report - 9 months ago
They have an unwarranted image as brutish and uncaring, but new research has revealed just how knowledgeable and effective Neanderthal healthcare was. The study, by the University of York, reveals that Neanderthal healthcare was uncalculated and highly effective - challenging our notions that they were brutish compared to modern humans. The researchers argue that the care provided was widespread and should be seen as a "compassionate and knowledgeable response to injury and illness." It is well known that Neanderthals sometimes provided care for the injured, but new analysis by t... more »
Neanderthals were artistic like modern humans
Jonathan KantrowitzatArchaeology News Report - 10 months ago
Scientists have found the first major evidence that Neanderthals, rather than modern humans, created the world's oldest known cave paintings - suggesting they may have had an artistic sense similar to our own. A new study led by the University of Southampton and the Max Planck Institute for Evolutionary Anthropology shows that paintings in three caves in Spain were created more than 64,000 years ago - 20,000 years before modern humans arrived in Europe. This means that the Palaeolithic (Ice Age) cave art - including pictures of animals, dots and geometric signs - must have been mad... more »

Archaeologists at The Australian National University (ANU) and the University of Sydney have provided a window into one of the most exciting periods in human history -- the transition between Neanderthals and modern humans. An archaeological dig in a cave in the Moravian region of the Czech Republic has provided a timeline of evidence from 10 sedimentary layers spanning 28,000 to 50,000 years ago. This is the period when our modern human ancestors first arrived in Europe. The dig, in a cave near the Czech border with Austria and around 150kms north of Vienna, has unearthed over 20... more » Dental plaque DNA shows Neandertals used 'aspirin'
