Others Cave popcorn , or cave coral, are small, knobby clusters of calcite Cave pearls are the result of water dripping from high above, causing small “seed” crystals to turn over so often that they form into near-perfect spheres of calcium carbonate Snottites are colonies of predominantly sulfur oxidizing bacteria and have the consistency of “snot”, or mucus Calcite rafts are thin accumulations of calcite that appear on the surface of cave pools Speleothems may also occur in lava tubes. Although sometimes similar in appearance to speleothems in caves formed by dissolution, these are formed by the cooling of residual lava within the lava tube. Speleothems formed from salt, sulfur and other minerals are also known. Speleothems made of pure calcium carbonate are a translucent white color, but often speleothems are colored by minerals such as iron , copper or manganese , or may be brown because of mud and silt particulate inclusions. Chemistry Many factors impact the shape and color of speleothem formations including the rate and direction of water seepage, the amount of acid in the water, the temperature and humidity content of a cave, air currents, the above ground climate, the amount of annual rainfall and the density of the plant cover. Most cave chemistry revolves around calcite ; CaCO 3 , the primary mineral in limestone. It is a slightly soluble mineral whose solubility increases with the introduction of carbon dioxide , CO 2. It is paradoxical in that its solubility decreases as the temperature increases, unlike the vast majority of dissolved solids. This decrease is due to interactions with the carbon dioxide, whose solubility is diminished by elevated temperatures; as the carbon dioxide is released, the calcium carbonate is precipitated. Most other solution caves that are not composed of limestone or dolostone are composed of gypsum calcium sulfate , the solubility of which is positively correlated with temperature.

He earned his Ph. D in Moscow under the supervision of anthropologist F. Debets in with a dissertation on The Origin of the Greeks, a work based on anthropometric studies of a sample of present-day Greek people. In , he returned to Greece as a researcher. This organization has had a long-standing dispute with the Greek Ministry of Culture, after the latter’s attempts to evict the association from the excavation site in the Petralona Cave, which was conceded to them after a contract.
Petralona skull Since the s, Poulianos has investigated early hominid remains found in a cave near Petralona , Greece, and has become known for controversial claims over their age. According to Poulianos, the Petralona Cave was accidentally discovered in by local villagers searching for a spring in the mountainside. The Petralona skull , specifically, was discovered in when it was removed from a rock in the cave. Early estimates at the time placed the age of the hominid remains to around 70, years old.
The scientists involved used electron spin resonance measurements and dated the age of the skull to between , and , years old research based on the detailed analysis of the Cave’s stratigraphy has proven that the original chronography of the skull is ultimately closer to the age of years claimed by Dr. Poulianos states that the age of the overall layer is approximately , years old, based on electron spin resonance measurements.
Some authors, on the other hand, believe that the Petralona cranium is derived from a unique class of hominids different from Homo erectus. Runnels and van Andel summarise the situation as such:
Researchers working at this site have uncovered more than archaeological items in at least ten levels, including 20 hearths ,  the skeletal remains of cave bears and have studied climate change during the Pleistocene. Of those still preserved, the best known is a mandible of a cave bear with three holes in the mandibular canal.
This marks the beginning of Paleolithic research in Slovenia. According to archaeologist Mitja Brodar , who discovered many of them, bones with holes so far not been found in Western Europe and they have been dated only to the end of the Mousterian and the beginning of the Aurignacian. Mitja Brodar assumes that these bones are still not recognized by the international research community due to the fact that most of the bones were found in France and the Paleolithic is still considered to be the French domain.

More than one million Australian men and women served in the war out of a total population of around seven million. Although it was ill-prepared for war, the Australian government had soon dispatched Royal Australian Air Force squadrons and personnel to serve with the Royal Air Force. German submarines and raiding ships operated in Australian waters throughout the war.
The most intensive and numerically largest part of Australia’s war effort came after the outbreak of hostilities with Japan in late The Australian mainland came under direct attack for the first time in , when Japanese aircraft made a major bombing attack on Darwin.

All the townspeople want to forgive him immediately, and they mock the titular priest for only being willing to give a measured forgiveness conditional on penance and self-reflection. They lecture the priest on the virtues of charity and compassion. Later, it comes out that the beloved nobleman did not in fact kill his good-for-nothing brother.
The good-for-nothing brother killed the beloved nobleman and stole his identity. Now the townspeople want to see him lynched or burned alive, and it is only the priest who — consistently — offers a measured forgiveness conditional on penance and self-reflection. The priest tells them: You forgive a conventional duel just as you forgive a conventional divorce. He further notes that this is why the townspeople can self-righteously consider themselves more compassionate and forgiving than he is.
Actual forgiveness, the kind the priest needs to cultivate to forgive evildoers, is really really hard. The fake forgiveness the townspeople use to forgive the people they like is really easy, so they get to boast not only of their forgiving nature, but of how much nicer they are than those mean old priests who find forgiveness difficult and want penance along with it.
Because GitHub is big and their study is automated, they manage to get a really nice sample size — about 2. They find that women get more! That makes their better performance extra impressive.

These plants are better adapted to dry and hot climates than the much more common C3 plants. Although it was already established that North Africa was arid in the early Last Glacial, Scholz et al. Return of Neanderthals to the Levant 80 to 55 ka [ edit[ edit ]tial causes for the initial extinction of modern humans from the Levant and subsequent replacement by Neanderthals around 80 ka include a short-term extreme environmental change in the Levant and environmental changes in the regions neighbouring the Levant.
The only long-term environmental change that has been found in the Levant at this period is an increase in rainfall Hallin et al. Alternatively, climate change could have connected the Neanderthal biome to the north, allowing Neanderthals to replace modern humans if Neanderthals were better pre-adapted to the new Levantine environment. It is also possible for climate change to have allowed the North African desert to expand and cut off the modern human Levantine biome from the larger African one.
This could have driven to extinction the modern human population with too few individuals to survive when disconnected from Africa, allowing Neanderthals to walk into the region. This could have happened even if modern humans were better adapted to the region than Neanderthals. In other words, in this case, the only advantage Neanderthals would have had in the Levant is that they could actually get there.
Environment[ edit[ edit ]arily to modern humans who arrived in the Levant in period particularly warm in both Eurasia and Africa, Neanderthals are thought to have entered the Levant in a period of increasing Eurasian coldness and aridity known as the Last Glacial Period Tchernov This is what Hallin et al. They found that at Amud, neither the goats nor the gazelle consumed arid-adapted C4 plants, indicating that the environment was not as dry as today.
Since owls are opportunistic hunters and will eat any small mammal, the bone assemblage they leave behind are thought to be accurate indicators of the environment, given that rodents, like beetles, are susceptible to small changes in temperature and humidity. The researchers did find changes in microfaunal bone assemblages, but all were expected by taphonomic bias.
