Modern human being traverse the Alps into parky Northern Europe about 45,000 years ago , intend they may have coexisted with Neanderthals in Europe for thousands of geezerhood longer than expert previously recall , concord to newfangled research .
The discovery — of 13 bone fragment belonging toHomo sapienswho occupy a cave in Germany between about 44,000 and 47,500 years ago — catalogue the oldest knownH. sapiensremains from Central and Northwest Europe , the researchers enounce . The determination also surprised the squad because , as they found , the climate in the region was glacial at that time .
Excavating the tool industry known as Lincombian-Ranisian-Jerzmanowician (LRJ) 26 feet (8 meters) deep at Ranis was a challenge and required scaffolding to support the trench.
" This shows that even these early groups ofHomo sapiensdispersing across Eurasia already had some capacity to adapt to such coarse climatic conditions,“Sarah Pederzani , an archaeologist at the University of La Laguna in Spain and the Max Planck Institute for Evolutionary Anthropology in Germany who result the paleoclimate sketch of the web site , said in astatement .

WhenH. sapiensarrived in Europe , they were not the first human lineage to enter the continent . Homo sapiens neanderthalensis — our closest extinct relative , which was well - adapt to the low temperature — occupy Europe fromat least 200,000 years agountil they went extinct around 40,000 years ago .
EarlyHomo sapiensprocessed the carcasses of deer but also of carnivores, including wolf, according to analyses of over 1,000 animal bones from Ranis.
Prior work discovered thatH. sapiensentered Southwest Europe by46,000 age ago . Much remains hotly consider about the nature of the fundamental interaction betweenH. sapiensand Neanderthals during this period , called the Middle - to - Upper Paleolithic passage ( 47,000 to 42,000 years ago ) , and how much our metal money might have sped up the Neanderthals ' death .
To investigate this mysterious transitional period , the researchers of three new study try artefact and the clime from that sentence , according totheir findings , published online Wednesday ( Jan. 31 ) in the journal Nature and intwostudiesin the journal Nature Ecology & Evolution .
Archaeologists previously unearthed a number of different " industries , " or Harlan Fisk Stone tool manufacturing styles , go out to this period — including the Lincombian - Ranisian - Jerzmanowician ( LRJ ) diligence — but it was indecipherable whetherH. sapiensor Neanderthals had crafted them .

" The Middle Paleolithic in Europe [ about 300,000 to 35,000 years ago ] is link with Neanderthals , while the Upper Paleolithic in Europe [ about 35,000 to 10,000 class ago ] is linked with modernH. sapiens , " subject area co - authorJean - Jacques Hublin , a paleoanthropologist at the Max Planck Institute for Evolutionary Anthropology , told Live Science . " The artifacts of the transitional point have sort of mixed feature . "
In one of the new studies , researchers examine LRJ artefact , which include elaborately craft , leaf - shaped Harlan F. Stone tools that were far-flung in Northern Europe from Germany to Britain .
The scientists focused on M of bone fragments affiliate with LRJ artefact in Ilsenhöhle ( Ilse ’s cave ) in Ranis , Germany . The research worker not only conduct new excavations at the site but also performed new analyses of remains found in the cave in the 1930s that are now in museum accumulation .

One of the new studiesfound the cave was used intermittently not only by denning hyenas and hibernating cave bears but also small groups of hominins — in all probability eitherH. sapiensor Neanderthals — who din on reindeer , woolly rhinoceros and horse . However , many bone fragment there were too small and broken for researchers to name them by their shape . Instead , the researchers analyzed protein and DNA take out from these remains to determine the bones ' origins .
Their enquiry uncovered the 13 bone sherd from about 44,000 to 47,500 yr ago .

" The unwashed sapience was these transitional assemblages of artifacts were made mostly by late Neanderthals , " Hublin said . " What we find with the LRJ is that it was not made by Neanderthals but byHomo sapiensmoving into Europe much sooner than we thought . "
analyse animal teeth and clappers from the cave suggest that when humans lived there , the field had very cold climates and steppe or tundra landscapes similar to those find in Siberia or northern Scandinavia today .
" Until recently it was thought that resilience to frigid - climate conditions did not appear until several thousand yr later , so this is a enthralling and surprising solution , " Pederzani said in the statement . " Perhaps cold steppes with large herd of prey animals were more attractive environments for these human grouping than previously appreciated . "
After chemical preparation and purification, very small animal teeth samples are loaded into an isotope ratio mass spectrometer to get oxygen stable isotope ratios, which can yield information about past climates that animals lived in.
These findings reveal thatH. sapiensarrived in Northwest Europe several thousand years before Neanderthals disappeared in Southwest Europe — a hint that the two groups may have interact . " So we now have another of import piece of what is a complicated puzzle " about the nature of the interactions between H. sapiens and Neanderthals , William Banks , an archaeologist with the French National Center for Scientific Research who did not take part in this bailiwick but write aneditorialabout it , told Live Science .
— When did Homo sapiens first appear ?
— What did the last common ascendent between humans and apes wait like ?
— Are Neanderthals and Homo sapiens the same species ?
" These finding suggest that alternatively ofH. sapiensreplacing Neanderthals in Europe in a speedy Orient - to - west wave as previously thought , " we seeHomo sapienscolonized the northern part of Europe first and lived there for several millenary on the periphery of the swinish Earth , " Hublin order . " I would sayHomo sapiensprobably last in these rather hostile environments because they had technical capabilities to adjust there . We do n’t see one wave ofHomo sapiensmoving into Europe and replacing Neanderthals , but successive pulsation of small groups moving into young territory , and then after several millennium finally completely replacing Neanderthals . "
Future research can investigate whether other Middle - to - Upper Paleolithic transition industries whose origins currently remain unsealed came fromH. sapiens , Hublin enjoin . " I would also like to examine Neanderthal remains from after contact withHomo sapiens , to see if there ’s any signs ofHomo sapiensDNA in them , " he added .
