"Peking Man" by Hyena gnawing?

<p> Hyenas wars "Beijing erectus" </ p> <p> </ p> <p> <wbr> </ p> <p> In the traditional way, Beijing described erectus is able to hunt using fire. </ .p> Figure / CFP <wbr> <p> <wbr> </ p> <p> Zhoukoudian site in a new round of excavation work is still going on. </ p> At the end of October, we had just spent " .Beijing erectus "first skull found 80 anniversary. Beijing erectus is always written in our history textbooks first chapter. The traditional way, he described to labor, can control fire, can create tools that can collect fruit, Hunt large animal that can select suitable accommodation .... No wonder people are not willing to accept the molecular biology of human origins discussion on Chile. <p> <wbr> </ p> <p> In fact, the existence of the ancient world and the image quite different point of .view: Beijing erectus is not a developed advanced burrowing, only around ten "people" teeth-Hui. </ p> Hyena is the owner of the cave. <p> <wbr> </ p> <p> 1 excluded factors < ./ p> <p> "Cannibalism" breed is unlikely to be </ p> <p> <wbr> </ p> <p> In Beijing: the discovery of Homo erectus, which by some archaeologists, such as "Peking Man ."named user, who step up to Health Canada as the immediate ancestor of modern people. </ p> The use of fire, tools, hunting the dawn of civilization has been sufficient to explain the problem, not just the animals caught grilled and eat .? <p> <wbr> </ p> <p> As research intensive, doubt has gradually appear. </ p> In 1929, France archaeologists step-asked why there are so many human skulls? date, a total of skulls, .6 pieces, skull fragments 12 pieces, teeth, and limb 157 is only 13 pieces of bone. Are these skull "headhunting" trophy? does the Beijing erectus to "eat"? several years later, Germany's Weimar Tun Shwe detail describes the Beijing erectus .fossils, that it have a blunt and stab wounds, and femur fracture mode is like a relic qiaoguxisui after ... <p> <wbr> </ p> <p> Objections of course. </ p> Mr. Pei wenzhong maintain .that this mark is the Hyena gnawing. It was also specially made experiments, find Hyena gnawing through bones really like Zhoukoudian fossil. Subsequently, related studies basically limited to domestic, academic one-sided opinion Beijing erectus is not present "cannibalism" breed. May .be new problems appeared: Hyena is which? <p> <wbr> </ p> <p> 2 marks on </ p> <p> Large teeth marks hyenas stay? </ p> <p> <wbr> </ .p> <p> Walk into the Zhoukoudian Museum, visitors may be mistaken for an ancient animal Museum here: Tiger, hyenas, swollen bone deer, hippo fossils are many, small mammals, and more mountains; human fossils full filled count only 40 pieces .... </ p> This ratio is somewhat exaggerated. Is it true that Beijing erectus faced the unexpected? <p> <wbr> </ p> <p> In 1970, scientists found a in Kenya with human bones of hyenas. .</ p> The same year was also found that the meat of animals often prey limbs chewing the rotten, primates are basically hands and feet are stripped. These discoveries make traditional interpretation. <p> <wbr> </ p> <p> .In 1993, the archaeologist NoelBoaz arrived at Zhoukoudian. </ p> Having carefully observed the bone bruises, he was surprised to discover that most human fossils with sharp puncture holes, slender bite or irregular fracture surface exactly corresponds to the hyena's canine teeth and the .lower jaw. But Mr. Tun Shwe "qiaoguxisui" marks for large extinct Hyena nor can do. Have a bone or even show signs of gastric acid corrosion, seems to be the customer of the restaurant after the feel of sorts to swallow it up again .. Skull injuries seems like hyenas hold head after biting down from the forehead, but also modern hyenas do not have a bite of facial indulgence (most animals are relatively thin facial bone). Keel mountain, basically no facial bone unearthed is one of the supporting .evidence. According to this view, the keel of the Beijing erectus probably are poor prey. <p> <wbr> </ p> <p> <wbr> Hyena is keel mountain cave of "masters". </ p> <p .> <wbr> </ p> <p> 3 in-depth troubleshooting </ p> <p> Erectus visit Mr. hyenas </ p> <p> <wbr> </ p> <p> By relying on bones of .bite cannot describe Beijing people's lives. </ p> The bones may be washed in water accumulate in this? this is unlikely. Keel mountain, either very fine-grained sediments, or very rough edged; the former means that the wind of deposition or .slow flowing water, while the latter is more likely to be a debris flow, unlike ordinary stream products. <p> <wbr> </ p> <p> Caves of ash layer how to explain it?, in fact, archaeologists have so .far not found Beijing erectus by fire of direct evidence. </ p> In fact, the dung heap spontaneous combustion can also produce ash layer. Straw combustion will stay "phytolith". After analysis, keel mountain cave ash layers are not found in the .SI-rich layer. Of course, would not exclude the Beijing people the possibility of collecting dung fires, but stool this thing a wide market demand, and difficult to store, before the advent of the livestock industry is very difficult to become a stable source .of fuel. <p> <wbr> </ p> <p> Then, hyenas bite is not means that Beijing erectus is not present "cannibalism" breed? unfortunately, archaeologists and indeed in some skulls were found on the traces of stone tools .. </ p> These scratches distribution clutter and lighter, more like when using the stone cut meat by-products. In most cases the stone marks will overwrite the bite that people may die from hyenas, and later it was like "a share" .. Of course, this cannot be excluded is the punishment for the offender, the victim suffering. <p> <wbr> </ p> <p> Don't keel mountain a living nor? this said. </ p> Keel mountain .caves in existence for at least 50 years, this period is likely to spent a lot of the tenant. But here's most of the bones and human behavior. In additionFor the sake of humanity and hyenas stealing meat, often in the vicinity of the entrance, .will leave traces; the occasional series doors what can always. They may even be the day to go, simply do not know the hyenas in cave sleeps ... <p> <wbr> </ p> <p> 4 related conclusions < ./ p> <p> To save face erectus </ p> <p> <wbr> </ p> <p> A personal bio, can only rely on the throat sound confused murmuring lung and clumsy gestures, all rely on finding rotten .meat and eat their own similar living ... </ p> This figure seems more suited to appear in the comic book, not suited as "human ancestors" candidate ". However, Europe and Africa, nearly all of Homo erectus is doing the .same thing. <p> <wbr> </ p> <p> "Homo erectus is Hunter" in the 1950s is standard, and there is a lot of the theory of evolution and ecology, but with the backing of fossils, issues emerge .. </ p> The original lot is considered to be hunting groups feature, now believes in rot food groups in the might exist. Overall, "Hunter" is now on the defensive. However, as the more in-depth study, "Hunter ."put on all the reversal is not known. <p> <wbr> </ p> <p> □ Entre (Beijing paleontology) <wbr> </ p>.
