That cave is 1. 'a natural home in the ground, large enough for human entry' is probably the most useful definition. this covers the enormous variety of caves that do occur but eliminates the many artificial tunnels and galleries incorrectly named caves. the size criterion is arbitrary and subjective, but practical, as it eliminates narrow openings irrelevant to explorers but very significant hydrologically, that may be better referred to as proto-caves, sub-conduits or fissures. a cave may be a single, short length of accessible passage, or an extensive and complex network of tunnels as long as the hundreds of kilometers in the flint mammoth cave system. most caves are formed by dissolution in limestone but sandstone caves, lava caves, glacier caves and tectonic caves also occur. marginal candidates for use of the name cave include riverbank undercuts and rock shelters of various origins. in some countries a cave is regarded as being a horizontal opening, as opposed to a pothole, which is a vertical opening. this usage is common in england but is not ubiquitous [9]. 2. a natural opening formed in the rocks below the surface of the ground large enough for a man to enter. it may consist of a single connected opening or a series of small or large chambers connected by galleries [20]. 3. a similar artificial opening [10]. related to cavern. synonyms: (french.) grotte, caverne; (german.) hohle, grotte; (greek.) speleon; (italian.) caverna, grotta; (russian.) pescera; (spanish.) cueva; (turkish.) magara; (yugoslavian.) pecina. pec, pestera, spilja, zijjalka, jama. see also active cave; bedding cave; cave system; grotto; sea cave.?

Dental morphology of the Dawenkou Neolithic population in North China: implications for the origin and distribution of Sinodonty
Abstract:
We compare the incidence of 25 nonmetric dental traits of the people of the Neolithic Dawenkou culture (6300-4500 BP) sites in Shandong Province, North China with those of other East Asian populations. The Dawenkou teeth had an overwhelmingly greater resemblance to the Sinodont pattern typical of Northeast Asia than to the Sundadont pattern typical of Southeast Asia. Multidimensional scaling using Smith's mean measure of divergence (MMD) statistic place the Dawenkou sample near the Amur and the North China-Mongolia populations in the area of the plot indicating typical Sinodonty. The existence of the Sinodont population in Neolithic North China suggests a possible continuity of Sinodonty from the Upper Cave population at Zhoukoudian (about 34,000-10,000 BP) to the modern North Chinese. The presence of Sinodonty in Shandong Province shows that the Japan Sea and East China Sea were strong barriers to gene flow for at least 3000 years, because at this time the Jomonese of Japan were fully Sundadont. In addition, we suggest that the descendants of the Dawenkou population cannot be excluded as one of the source populations that contributed to sinodontification in Japan. (C) 2003 Elsevier Ltd.
