Was Israel the birthplace of modern man?


Findings from Tel Aviv University archaeologists locate remains of Homo sapiens in Israel 400,000 years ago

It has long been believed that modern man emerged from the continent of Africa 200,000 years ago. Now Tel Aviv University archaeologists have uncovered evidence thatHomo sapiens roamed the land now called Israel as early as 400,000 years ago ― the earliest evidence for the existence of modern man anywhere in the world.

The findings were discovered in the Qesem Cave, a pre-historic site located near Rosh Ha'ayin that was first excavated in 2000. Prof. Avi Gopher and Dr. Ran Barkai of Tel Aviv University's Department of Archaeology, who run the excavations, and Prof. Israel Hershkowitz of the university's Department of Anatomy and Anthropology and Sackler School of Medicine, together with an international team of scientists, performed a morphological analysis on eight human teeth found in the Qesem Cave.

This analysis, which included CT scans and X-rays, indicates that the size and shape of the teeth are very similar to those of modern man. The teeth found in the Qesem Cave are very similar to other evidence of modern man from Israel, dated to around 100,000 years ago, discovered in the Skhul Cave in the Carmel and Qafzeh Cave in the Lower Galilee near Nazareth. The results of the researchers' findings are being published in the American Journal of Physical Anthropology.

Lascaux: virtual cave visit

In 1940 the cave of Lascaux was discovered by four teenagers. The cave is located in the French region of Dordogne and hosts more then 2000 cave paintings from the Paleolithicum: animals, humans but also more abstract drawings.

These cave paintings are incredibly well preserved and give us a good idea about the life at that time. The paintings however are threatened by bacteria and fungal infections. The government closed the cave in 1963 in an attempt to save the paintings from further deterioration.

A virtual visit to the cave however is still possible: by clicking on the picture below you can discover the different panels and find additional info about each painting.

Enjoy!

Lascaux cave: History

Lascaux is the setting of a complex of caves in southwestern France famous for its Paleolithic cave paintings. The original caves are located near the village of Montignac, in the department of Dordogne. They contain some of the best-known Upper Paleolithic art. These paintings are estimated to be 17,300 years old.

 They primarily consist of primitive images of large animals, most of which are known from fossil evidence to have lived in the area at the time. In 1979, Lascaux was added to the UNESCO World Heritage Sites list along with other prehistoric sites in the Vézère valley.

Tourists to Spend New Year's Eve in Miraculous Bulgarian Cave

Tourists and speleologists have been increasingly
enthusiastic about the Yagodinska Cave.
Cave-lovers from a tourist club called "Rodopeya" are going to welcome the new year in the Yagodinska Cave in Southern Bulgaria.

The Yagodinska Cave is located in the Rhodope Mountain; it is long 10 km and has three levels, of which the lowest one is equipped with electricity and fit for organized tourism with 1.1-km path, and special entrance tunnels.

The first level of the Yagodinska Cave is a valuable archaeological site as in the 4th millennium BC it was inhabited by pottery makers with had special ovens.

The cave is renowned for its unique forms and rocks with different colors; it features a permanent temperature of 6 degrees Celsius.

In the recent years, speleologists from the Rodopeya Club and tourists who arrive to the nearby villages of Yagodina and Buynovo hold New Year's celebrations inside the cave. A number of wedding ceremonies have also been held there recently.

The Yagodinska Cave is one of Bulgaria's "100 National Tourist Sites"; in 2010, it was visited by 51 000 tourists from Bulgaria and abroad.

Fossil finger bone yields genome of a previously unknown human relative


Study suggests 'Denisovans' shared the stage with early modern humans and Neanderthals and interbred with ancestors of modern Melanesians

A 30,000-year-old finger bone found in a cave in southern Siberia came from a young girl who was neither an early modern human nor a Neanderthal, but belonged to a previously unknown group of human relatives who may have lived throughout much of Asia during the late Pleistocene epoch. Although the fossil evidence consists of just a bone fragment and one tooth, DNA extracted from the bone has yielded a draft genome sequence, enabling scientists to reach some startling conclusions about this extinct branch of the human family tree, called "Denisovans" after the cave where the fossils were found.

The findings are reported in the December 23 issue of Nature by an international team of scientists, including many of the same researchers who earlier this year published the Neanderthal genome. Coauthor Richard Green of the University of California, Santa Cruz, played a lead role in the analysis of the genome sequence data, for which a special portal was designed on the UCSC Genome Browser. The team was led by Svante Pääbo of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany.

Genome of extinct Siberian cave-dweller linked to modern-day humans


Sequencing of ancient DNA reveals new hominin population that is neither Neanderthal nor modern human
Researchers have discovered evidence of a distinct group of "archaic" humans existing outside of Africa more than 30,000 years ago at a time when Neanderthals are thought to have dominated Europe and Asia. But genetic testing shows that members of this new group were not Neanderthals, and they interbred with the ancestors of some modern humans who are alive today.

The journal Nature reported the finding this week. The National Science Foundation's Behavioral and Cognitive Sciences Division partially funded the research.

An international team of scientists led by Svante Pääbo at the Max Planck Institute of Evolutionary Anthropology in Leipzig, Germany, used a combination of genetic data and dental analysis to identify a previously unknown population of early humans, whom the researchers call "Denisovans." The name was taken from Denisova Cave in southern Siberia where archaeologists from the Russian Academy of Sciences recovered a bone in 2008.

Genetic sequencing of DNA extracted from a finger bone of a 5-10-year-old girl from the cave revealed that she was neither Neanderthal nor a modern human, but shared an ancient origin with Neanderthals. The genetic analysis also showed she had a very different history since splitting from Neanderthals, the researchers concluded.

15 km drink Avalon

On Friday december 17th, our caving club (grotto), SC Avalon, gave a party for the discovery of more than 15 km of virgin cave passage in Belgium since the 80's.

Despite the bad weather (snow) and slippery roads, 63 persons turned up. Not only members from VVS, but also people from UBS and Speleo Nederland joined.



Our long-time chairman, Paul De Bie, gave a nice speech and a short presentation about some of the more important / bigger discoveries. (which you can download here).

Exploration in Belgium is really not the same as in some other countries. People were awed by the immense amount of labour and the tons and tons of mud, pebbles and rock that had to be moved. Most of the times the digs don't end up revealing anything spectacular, but once in a while a real beauty is discovered (like the "Grotte du Bois de Waerimont" and the "Grotte des Emotions"). You can find the complete list of discoveries on this page.

After the presentation people could enjoy the exposition with some nice pictures and surveys of these discoveries, as well as some drawings and paintings from Annette Van Houtte.



A cabinet filled with archeological and paleontological objects discovered during various digs was also getting a lot of attention. Especially the skull of a cave bear (Ursus speleaus) was impressive.



If your interested in exploration and you want to follow us working towards the next discovery, I can recommend our grotto's blog: http://scavalon.blogspot.com

Update 28/12/2010: As of today a huge new picture gallery is available here, covering not only the clubs discoveries but also some pictures from visits to some of the most beautiful caves in the world.

A special word of thanks goes to our grotto's sponsors Proviron, De Berghut and Chronos.

Journées 2010 de Spéléologie Scientifique

The JSS 2010, an annual cave science conference organised by the Belgian Caving Federation (UBS) and the Belgian Center for Karst Studies held place in Han-sur-Lesse on 11 and 12 december.

This years main topic was the "VMR". The VMR is a book titled "Les Cavernes et les Rivières Souterraines de la Belgique" published by E. Van Den Broeck, E.A. Martel and E. Rahir in 1910. It's a huge book in two parts that described all the caves and underground rivers in Belgium for the first time on a scientific manner. Up until today it's never been equaled. Though there are many new insights and discoveries it's still a reference book for all who are studying the Belgian underground, whether as a scientist or a caver. As it is quite rare and wanted, the price is skyrocketing (I've seen it go for over 300 EUR). Luckily the book has been completely digitized and will be available somewhere in 2011.

Vleermuizen in winterslaap

In België en Nederland komen zo'n 20 verschillende vleermuizen voor (gladneuzen en hoefijzerneuzen), waarvan een aantal zeer zeldzaam is.
(ↄ) Public domain - Bat on ceiling
Omdat er in de koude wintermaanden amper insecten zijn, houden ze een winterslaap: Hun lichaamstemperatuur daalt tot 5°C en ze vertragen hun ademhaling, hartritme en stofwisseling. Naast steengroeven en holle bomen zijn onze grotten een van de plekken bij uitstek om de winter door te brengen: ze zijn koel en vochtig, en gegarandeerd vorstvrij.

Voor verschillende vleermuissoorten, zoals de ingekorven vleermuis, vormt verstoring en het ongeschikt worden van overwinteringsplaatsen, zoals forten en ijskelder, een belangrijke bedreiging.  Om de populaties niet te verstoren tijdens hun winterslaap, worden volgende grotten voorzien van een extra slot, zodanig dat ze niet toegankelijk zijn van 1 november tot 31 maart:

7 Bulgarians Safe and Sound after Rescue from Flooded Cave

The rescue operation to free four adults and three teenagers who have been stranded in the Duhlata cave in western Bulgaria for two days, ended successfully late on Sunday.

The accident occurred after Saturday torrential rains and rising underground waters flooded thecave's lower passages.

The rescue teams have worked all through the night using heavy equipment such as excavators. The head of the operation told Darik radio he was optimistic regarding the outcome, adding this could be an unprecedented rescue effort in Bulgaria over its large scale.

The four adults are believed to be experienced in speleology with over 20 years of practice and to have all basics to survive inside, along with the teenagers, for several days. Rescuers further said the stranded people are in a safe part of the cave.

Nevertheless, Civil Defense pointed out it is reckless to not watch the weather forecast before undertaking such adventures.

The seven people entered the cave at about 8 pm Friday night. The kids are aged 11, 13 and 14, and are known to be teenage climbers. They are from Sofia, Pernik, and Karlovo.

The Duhlata cave is long 18 km and is known as the more complex underground labyrinth in Bulgaria; it has seven levels. It is near the village of Bosnek, alongside theStruma River.

The cave is secured with a door of metal bars but the speleologists received the key for the door from the mayor of the nearby village, not expecting that the torrential rains will affect their trip.

Mass Rescue Effort to Free Cave-Stranded Bulgarian Adults, Teens

Civil Defense teams have worked round-the-clock overnight to free the
7 people stranded in a cave in western Bulgaria.
The rescue operation to free four adults and three teenagers who have beenstranded in the Duhlata cave in western Bulgaria for 24 hours now is continuing, Civil Defense informed Sunday.

The incident occurred after the Saturday torrential rains and rising underground waters flooded the cave's lower passages.

According to the report, there is one rescue team inside the cave and two more on standby outside. They have worked all through the night using heavy equipment such as excavators. The head of the operation told Darik radio he was optimistic regarding the outcome, adding this could be an unprecedented rescue effort in Bulgaria over its large scale.

The four adults are believed to be experienced in speleology with over 20 years of practice and to have all basics to survive inside, along with the teenagers, for several days. Rescuers further say the stranded people are in a safe part of the cave. They hope to be able to reach them by noon Sunday.

Nevertheless, Civil Defense point out it is reckless to not watch the weather forecast before undertaking such adventures.

The Civil Defense Head, Stefko Burdzhev is travelling to the incident's location Sunday.

7 Bulgarians Stranded in Flooded Cave

The entrance of the Duhlata cave looks deceptively small.
It is secured with a door of metal bars.

The cave is secured with a door of metal bars but the speleologists received the key for the door from the mayor of the nearby village, not expecting that the torrential rains will affect their trip.

The rescue units of experienced cave explorers are certain that the strandedpeople are safe because even if the low passages of the cave are flooded, it also has several higher floors where they probably found refuge.

The rescue units got a bulldozer to start smashing the rocks at the site of water springs starting at one side of the cave in order to release more water from thecave passages.

Cops recover large cache of arms from cave in J&K

Delhi Police on Wednesday claimed to have recovered a large cache of arms and ammunitions from a cave in a forest in Jammu and Kashmir following a trail given by a "most wanted" Hizb militant who was arrested here last month.

Acting on the information, a joint team of Special Cell and JK Police on November 25 recovered a AK-56 rifle, four magazines, 120 rounds, a hand grenade, two matrix, documents, diary and combat gun pouch (Bandolier) from a cave in Richbagla forest in Rajouri, Additional DCP (Special Cell) Shibhesh Singh said.

After evading arrest for nearly a decade, Hizbul Mujahideen's self-styled divisional commander Mohammed Abdullah Inquilabi referred to as 'Mr Surrender' was arrested in Delhi on November 14.

During interrogation, Singh said, Inquilabi told investigators that during his school days he came in contact with a Maulavi in PoK, who motivated him to join militancy.

"The Maulavi introduced him to leader of Peer Panjal Regiment of Hizbul Mujahideen in PoK. After undergoing training in weapon handling in PoK, he came to JK along with other militants.

7 Bulgarians Safe and Sound after Rescue from Flooded Cave

The rescue operation to free four adults and three teenagers who have been stranded in the Duhlata cave in western Bulgaria for two days, ended successfully late on Sunday.

The accident occurred after Saturday torrential rains and rising underground waters flooded thecave's lower passages.

The rescue teams have worked all through the night using heavy equipment such as excavators. The head of the operation told Darik radio he was optimistic regarding the outcome, adding this could be an unprecedented rescue effort in Bulgaria over its large scale.

The four adults are believed to be experienced in speleology with over 20 years of practice and to have all basics to survive inside, along with the teenagers, for several days. Rescuers further said the stranded people are in a safe part of the cave.

Nevertheless, Civil Defense pointed out it is reckless to not watch the weather forecast before undertaking such adventures.

The seven people entered the cave at about 8 pm Friday night. The kids are aged 11, 13 and 14, and are known to be teenage climbers. They are from Sofia, Pernik, and Karlovo.

The Duhlata cave is long 18 km and is known as the more complex underground labyrinth in Bulgaria; it has seven levels. It is near the village of Bosnek, alongside theStruma River.

The cave is secured with a door of metal bars but the speleologists received the key for the door from the mayor of the nearby village, not expecting that the torrential rains will affect their trip.

The cave is secured with a door of metal bars but the speleologists received the key for the door from the mayor of the nearby village, not expecting that the torrential rains will affect their trip.

The rescue units of experienced cave explorers are certain that the strandedpeople are safe because even if the low passages of the cave are flooded, it also has several higher floors where they probably found refuge.

The rescue units got a bulldozer to start smashing the rocks at the site of water springs starting at one side of the cave in order to release more water from thecave passages.

Cops recover large cache of arms from cave in J&K

Delhi Police on Wednesday claimed to have recovered a large cache of arms and ammunitions from a cave in a forest in Jammu and Kashmir following a trail given by a "most wanted" Hizb militant who was arrested here last month.

Acting on the information, a joint team of Special Cell and JK Police on November 25 recovered a AK-56 rifle, four magazines, 120 rounds, a hand grenade, two matrix, documents, diary and combat gun pouch (Bandolier) from a cave in Richbagla forest in Rajouri, Additional DCP (Special Cell) Shibhesh Singh said.

After evading arrest for nearly a decade, Hizbul Mujahideen's self-styled divisional commander Mohammed Abdullah Inquilabi referred to as 'Mr Surrender' was arrested in Delhi on November 14.

During interrogation, Singh said, Inquilabi told investigators that during his school days he came in contact with a Maulavi in PoK, who motivated him to join militancy.

"The Maulavi introduced him to leader of Peer Panjal Regiment of Hizbul Mujahideen in PoK. After undergoing training in weapon handling in PoK, he came to JK along with other militants.
