The Last Supper

The Last Supper Of The Hominids Establishes The Times They Lived At
The Sites

ScienceDaily (July 14, 2009) — In the French cave of Arago, an
international team of scientists has analyzed the dental wear of the
fossils of herbivorous animals hunted by Homo heidelbergensis. It is
the first time that an analytical method has allowed the establishment
of the length of human occupations at archaeological sites. The key is
the last food that these hominids consumed.

For many years, the mobility of the groups of hominids and how long
they spent in caves or outdoors has been a subject of discussion among
scientists. Now, an international team headed by researchers from the
Catalan Institute of Human Paleoecology and Social Evolution (IPHES)
in Tarragona has based its studies on the dental fossils of animals
hunted by hominids in order to determine the vegetation in the
environment and the way of life of Homo heidelbergensis.

Florent Rivals is the main author and a researcher from the Catalan
Institute for Research and Advanced Studies (ICREA), attached to the
IPHES in Tarragona. "For the first time, a method has been put forward
which allows us to establish the relative length of the human
occupations at archaeological sites as, up until now, it was difficult
to ascertain the difference between, for example, a single long-term
occupation and a succession of shorter seasonal occupations in the
same place", he explained to SINC.

In the study, recently published in the Journal of Human Evolution,
the researchers analyze the dental wear of the ungulates (herbivorous
mammals) caused by microscopic particles of opaline silica in plants.
These marks appear when eating takes place and erase the previous
ones. This is why they are so useful.

Thanks to the "last supper phenomenon", the scientists have been able
to analyze the last food consumed by animals such as the Eurasian wild
horse (Equus ferus), the mouflon (Ovis ammon antiqua) and the reindeer
(Rangifer tarandus). "This method allows us to confirm the seasonal
nature of the occupation", Rivals added. According to the team, the
microwear of the teeth is sensitive to seasonal changes in the diet.

The application has allowed the researchers to estimate the length of
the occupation of the site from the Lower Paleolithic Age in the cave
of Arago (France) by the number of marks on the fossils and,
therefore, the variation in the diet of several species of herbivores,
as "each season presented food resources which were limited and
different in the environment", the paleontologist clarified.

High and low periods of occupation

After confirming the hypothesis in present-day animals whose age and
date of death was known to the scientists, the researchers
demonstrated that, if a group of animals is seen during a specific
season (a short-term occupation), the signs of dental wear undergo
little variation. But if the occupation lasts several seasons, the
dental marks are more diverse.

"If the animals are hunted during long periods of occupation, more
variable dental wear would be expected", Rivals declared. In the case
of the French cave of Arago, the study of the dental wear confirms
that it was occupied in different ways. "With this method, we were
able to prove that at the site, which belonged to Homo
heidelbergensis, there is evidence of differing mobility, as there
were highly mobile groups and others with little mobility", the
scientist confirmed.

The Spanish and German researchers have combined this application with
multidisciplinary studies of archaeological sites in order to apply it
to other settlements of the Mid-Paleolithic Age such as Payre
(France), Taubach (Germany) and Abric Romani (Spain).

Characterization of settlement patterns is one of the core concepts in
archeological research. The duration of an occupation is usually
estimated through zooarchaeology (e.g., density of remains,
cementochronology) and is limited by taphonomic processes and sample
size. We propose a new application of dental wear methods for
estimating the relative duration of hominid settlements in Paleolithic
sites. Dental microwear is known to be sensitive to seasonal changes
in diet. In this new application we use microwear scratch counts to
estimate the variation in the dietary signal of various ungulate
species. We propose that this variation is correlated to the duration
of site occupation. Each season presents a limited and different set
of food resources available in the environment. If animals are sampled
only during a specific season (i.e., during a short term occupation)
then they would be expected to have a dental wear signal with little
variation. On the other hand, a greater diversity of food is available
across different seasons. Therefore, if game animals are hunted
through various seasons during long occupation periods, then they
would be expected to have more variable dental wear. The application
of this technique to the Middle Paleolithic site of Arago Cave
(France), where various types of occupations occurred, supports this
hypothesis. When combined with multidisciplinary studies of
archaeological localities (seasonality in particular), this new
application of dental wear analysis presents valuable information
about hominid settlements and behavior. We contextualize our data with
results from lithic and zooarchaeological analyses from Arago. These
results reveal the presence of both high and low mobility groups of
Homo heidelbergensis throughout the sequence of the Arago Cave.

First Europeans were cannibals: archaeologists

First Europeans were cannibals: archaeologists

The remains of the "first Europeans" discovered at an archaeological site in northern Spain have revealed that the prehistoric men were cannibals, who particularly liked the flesh of children.

"We know that they practised cannibalism," said Jose Maria Bermudez de Castro, a co-director of the Atapuerca project, a UNESCO World Heritage Site.

A study of the remains revealed that they turned to cannibalism to feed themselves and not as part of a ritual, that they ate their rivals after killing them, mostly children and adolescents.

"It is the first well-documented case of cannibalism in the history of humanity, which does not mean that it is the oldest," he said.

The remains discovered in the caves "appeared scattered, broken, fragmented, mixed with other animals such as horses, deer, rhinoceroses, all kinds of animals caught in hunting" and eaten by humans, he said.

"This gives us an idea of cannibalism as a type gastronomy, and not as a ritual."

The Atapuerca caves were first discovered in the late 19th century, when a tunnel was blasted through the mountain for a railway line.

"But at the time in Spain, there was not enough scientific knowledge to begin research," said another co-director, Eudald Carbonell.

The first excavations did not take place until 1978, then "in 1984, we found 150 human remains".

In 1992, they found a complete intact skeleton, and two years later, they discovered remains dating back more than 800,000 years.

fortunate that the thing still plays, as per the recorded sample.

The Divje Babe flute, that is dated at around 43,000 years ago, has
been suggested as Neanderthal made.

"Music did not directly produce a more effective subsistence economy
and greater reproductive success, he concluded, but it might have
fostered social cohesion and new forms of communication, which
indirectly contributed to expansion of modern humans to the detriment
of the culturally more conservative Neanderthals." Then again, he
never saw what went on the back of the cave when the flutist really
put on the sounds.

Golden oldies

Discovery of the world's oldest known musical instrument, a 35,000-
year-old flute, suggests the first Europeans had a fairly
sophisticated culture.

By Thomas H. Maugh II
Los Angeles Times

The wing bone of a griffon vulture with five precisely drilled holes
in it is the oldest known musical instrument, a 35,000-year-old relic
of an early human society that drank beer, played flute and drums and
danced around the campfire on cold winter evenings, researchers said.

Excavated from a cave in southwest Germany, the nearly complete flute
suggests that the first humans to occupy Europe had a fairly
sophisticated culture, complete with alcohol, adornments, art objects
and music that they developed there or even brought with them from
Africa when they moved to the new continent 40,000 years or so ago.

"It is not too surprising that music was a part of their culture,"
said archaeologist John J. Shea of Stony Brook University, who was not
involved in the research. "Every single society we know of has music.
The more widespread a characteristic is today, the more likely it is
to spread back into the past."

The making of music probably extended even further back into the past,
he said, but the flute may represent "the first time that people
invested time and energy in making instruments that were (durable
enough to be) preserved."

The flute was discovered last summer in the Hohle Fels cave, about 14
miles southwest of the city of Ulm, by archaeologist Nicholas J.
Conard of the University of Tubingen in Germany. Conard described the
find in a report published online by the journal Nature

"It's unambiguously the oldest instrument in the world," Conard told
The Associated Press.

Other archaeologists agreed with Conard's assessment.

April Nowell, a Paleolithic archaeologist at the University of
Victoria in Canada, said the flute predates previously discovered
instruments, "but the dates are not so much older that it's surprising
or controversial." Nowell was not involved in Conard's research.

In 1995, archaeologist Ivan Turk excavated a bear bone artifact from a
cave in Slovenia, known as the

But other archaeologists, including Nowell, have challenged that
theory, suggesting instead that the twin holes on the 4.3-inch-long
(11-centimeter-long) bone were made by a carnivore's bite.

Turk did not respond to an Associated Press e-mail seeking comment.

The cave is the same one where Conard found the recently described
40,000-year-old Venus figurine in the same layer of sediment, the
oldest known representation of the female form, and a host of other

The cave, which had been occupied for millennia, "is one of the most
wonderfully clear windows into the past, where conditions of
preservation are just right," Shea said.

The reconstructed flute, a little under 9 inches long, was found in 12
pieces in a layer of sediment nearly 9 feet below the cave's floor.

The surfaces of the flute are in excellent condition and reveal many
details about its manufacture. The maker carved two deep, V-shaped
notches into one end, presumably to form the end into which the
musician blew, and four fine lines near the finger holes. The other
end is broken off, but Conard estimates the intact flute was probably
2 to 3 inches longer.

In 2004, Conard found a 30,000-year-old, 7-inch, three-holed ivory
flute at the nearby Geissenklosterle cave, and he has found fragments
of others. Combined, the finds indicate the development of a strong
musical tradition in the region, accompanied by the development of
figurative art and other innovations, Conard said.

Music did not directly produce a more effective subsistence economy
and greater reproductive success, he concluded, but it might have
fostered social cohesion and new forms of communication, which
indirectly contributed to expansion of modern humans to the detriment
of the culturally more conservative Neanderthals.
