A trove of
Neanderthal fossils including bones of children and adults, discovered in a
cave in Greece
hints the area may have been a key crossroad for ancient humans, researchers
say.
The timing of
the fossils suggests Neanderthals http://www.livescience.com/28036-neanderthals-facts-about-our-extinct-human-relatives.html
and humans may have at least had the opportunity to interact, or cross paths,
there, the researchers added.
Neanderthals
are the closest extinct relatives of modern humans, apparently even
occasionally interbreeding with our ancestors http://www.livescience.com/23730-neanderthals-modern-humans-interbreeding.html
Neanderthals
entered Europe before modern humans did, and
may have lasted there until about 35,000 years ago, although recent findings
have called this date into question
To learn more
about the history of ancient humans, scientists have recently focused on Greece .
"Greece lies directly on the most likely route of
dispersals of early modern humans and earlier hominins into Europe from Africa
via the Near East," paleoanthropologist Katerina Harvati at the University of TFCbingen
in Germany
told LiveScience. "It also lies at the heart of one of the three Mediterranean
peninsulae of Europe, which acted as refugia for plant and animal species,
including human populations, during glacial times 97 that is, areas where
species and populations were able to survive during the worst climatic
deteriorations."
"Until
recently, very little was known about deep prehistory in Greece , chiefly
because the archaeological research focus in the country has been on classical
and other more recent periods," Harvati added.
Harvati and
colleagues from Greece and France analyzed remains from a site known as
Kalamakia, a cave stretching about 65 feet (20 meters) deep into limestone
cliffs on the western coast of the Mani
Peninsula on the mainland of Greece . They
excavated the cave over the course of 13 years. Amazing Caves: Photos Reveal
Earth's Innards http://www.livescience.com/16410-amazing-caves-gallery.html
The archaeological deposits of the cave date back to between about 39,000 and
100,000 years ago to the Middle Paleolithic period. During the height of the
ice age, the area still possessed a mild climate and supported a wide range of
wildlife, including deer, wild boar, rabbits, elephants, weasels, foxes,
wolves, leopards, bears, falcons, toads, vipers and tortoises.
In the cave,
the researchers found tools such as scrapers made of flint, quartz and
seashells. The stone tools were all shaped, or knapped, in a way typical of
Neanderthal artifacts http://www.livescience.com/20967-neanderthals-europe-cave-art.html
Now, the
scientists reveal they discovered 14 specimens of child and adult human remains
in the cave, including teeth, a small fragment of skull, a vertebra, and leg
and foot bones with bite and gnaw marks on them. The teeth strongly appear to
be Neanderthal, and judging by marks on the teeth, the ancient people
apparently had a diet of meat and diverse plants.
"Kalamakia,
together with the single human tooth from the nearby cave site of Lakonis, are
the first Neanderthal remains to be identified from Greece ," Harvati said. The
discoveries are "confirmation of a thriving and long-standing Neanderthal
population in the region."
These findings
suggest "the fossil record from Greece potentially holds answers about the
earliest dispersal of modern humans http://www.livescience.com/22529-oldest-bones-modern-humans-asia.html and earlier hominins into Europe, about
possible late survival of Neanderthals and about one of the first instances
where the two might have had the opportunity to interact," Harvati said.
In the future,
Harvati and her colleagues will conduct new fieldwork in other areas in Greece to address mysteries such as potential
coexistence and interactions between Neanderthals and modern humans, the spread
of modern and extinct humans into Europe and
possible seafaring capabilities of ancient humans.
"We look
forward to exciting discoveries in the coming years," Harvati said.
The scientists
detailed their findings online March 13 in the Journal of Human Evolution.
