The occipital torns refers to a thickened band of bone usually betWeen the superior and supreme nuchal lines. Since Weidenreich published his study in 1940, the size of the oCCipital tornshas been thought to decrease over the course of human evolution. A strong torns can be aden incrania of Homo e.rectus, whereas a relatively weak one is presented in HOrn o sa ̄s. A well--developed occipital torns therefore may be useful in the diagnosis of Homo erectus.Recent finds and dating resultS in China indicate that extensive...

The occipital torns refers to a thickened band of bone usually betWeen the superior and supreme nuchal lines. Since Weidenreich published his study in 1940, the size of the oCCipital tornshas been thought to decrease over the course of human evolution. A strong torns can be aden incrania of Homo e.rectus, whereas a relatively weak one is presented in HOrn o sa ̄s. A well--developed occipital torns therefore may be useful in the diagnosis of Homo erectus.Recent finds and dating resultS in China indicate that extensive variahon occurred in thedevelopment of the occipital torns during the period 190--230 by B.P. Thus, some authors havesuggested the co--existence of Hobo erectal and Homo swim in China during that time. However. it is also possible that the occipital torns is not a genehc marker, but rather may be anadaptive skeletal response to veriable nuchal muscle action.To help establish whether middle Pleistocene oCCipital variations in China reflecttaxonomy, adaptation, dimorphism, or mechanical consequences of differing cramal form, observations and measurementS were taken on 507 modern human skulls. These skulls representpopulations of Mongoloid affinity across a wide range of adaptive conditions, including samples of American indians, Aleuts. North Chinese. and from Yunnan.In eaCh skull the degree of oeeipital torns development was recorded and 14 measurementswere taken rcflCCting cramal and occipital forms. The degree of occipital torns development wasdivided intO four categorics:0: No torns. Supreme nuchal line (SMNL) cannot be idenhficd. Superior nuchal line afL)may or may not be discernible. The surface between SMNL and SNL is smooth and levelwith the occipital and nuchal planes.l: Slight elevation betWeen SMNL and SNL, and SMNL shows a trace only. Alternatively,two small rounded elevations, one on right and left sides, appear between SMNL andSNL, and the SMNL presents itS median portion only.2: Moderately developed elevation between SMNL and SNL. The SMNL and SNL arc didtinct. The SNL extends laterally toward asterian.3: Strong elevation with distinct demarcations (SMNL and SNL). The SMNL and SNL are'pronounced and elevated. The SNL extends laterally toward asterian.ResultS of these observations are given in Table 1. Testing the occurrence of each degree ofdripital torns development, xZ testS indicate that there are no significant differences betweendifferent populations in either the male or the female samples (P>0.05). There is. however, aaignificant difference between male and female samples within populations (P < 0.01).To examine the correlation between occipital torns development and cramal or occipitalform, statistics for the 14 measurements are given by sex and population. Analysis suggestS thatonly occipital angle and nuchal plane length may be correlated with torns development withinmale or female samples of some (but not all) populations (Tables 2 alld 3). This correlation isnot widespread, and the development of the occipital torns is not necessarily affected by overallcramal and oedpital form.To summarize, the incidence of each category of oCCipital torns development appears tO beidentical across populations, controlling for sex. Moreover, the incidence is not sttongly affected by geographic (environmental) differences in male or female samples of populations havingthe same raceal affinity. Genetic factors thus may be operating in the development of theOCCipital torns. In this sense, oedpital torns size may be considered a genetic marker.Wide variahon in the development of the oCCipital torns can be talced back to Homo erectus. Comparedespecially with torns shape, the development (size) of the torns does not appear to be an cffcobye taxonomic character, although genetically controlled.This work was funded by SFPPAS of Acadcmia Sinica, the Office of Fellowships andGrants of the Smithsonian institution, and a grant from the American Museum of Natllral History.

The records of local history and oral account of local people show that the sediments inside Dadong cave have been greatly disturbed by local people for various reasons in the past 100 years. The grand main hall of the cave measures 250m from its back wall to the entrance and covers an area of roughly 9900m 2. The deposit is estimated to be 19 5m thick near the entrance. The middle and lower part of the sequence are generally preserved. Therefore,comparing with the grand scale and the preserved portion of...

The records of local history and oral account of local people show that the sediments inside Dadong cave have been greatly disturbed by local people for various reasons in the past 100 years. The grand main hall of the cave measures 250m from its back wall to the entrance and covers an area of roughly 9900m 2. The deposit is estimated to be 19 5m thick near the entrance. The middle and lower part of the sequence are generally preserved. Therefore,comparing with the grand scale and the preserved portion of the deposit, the man made disturbance of Dadong is limited. The sediments inside the cave consist of two parts in source. One comes from the cave itself, which includes blocks and fragments of limestone, travertine. The other includes clay, sand, gravel, fragments of limestone which were brought from the hill slope outside cave by ground water and loess like clay which may be brought into cave by wind. In addition, animal and human fossils, stone artefacts, evidences of using fire(ash, charcoal, burnt bones) and etc. are in relation with human activities mainly. According to composite analysis, the sediments above mentioned have no direct relation to river. In other words, they have been deposited within the cave after the cave separated itself from the underground river. Preliminary observation on the exposure at the front area of main hall, the upper part of sediments can be divided into 8 layers from top to base as follows: Layer 1\ The first travertine, 5—10cm, slightly brown. 130ka based on U series dating. Layer 2\ Brown sandy clay, powdered clay with breccia, 2 5—4m. Abundant animal fossils and cultural relics are present. Layer 3\ The second travertine, 5—12cm, greyish brown. Stone artefacts, charcoal and animal fossils are present. 200ka based on U series dating. Layer 4\ Greyish brown sandy clay, clay with breccia, 1—2 5m. Abundant stone artefacts and animal fossils, as well as charcoal are present. Layer 5\ The third travertine, 10—25cm, greyish brown. 260ka based on U series dating. Layer 6\ Brown sandy clay with breccia, 0 5—1m. Abundant stone artefacts and animal fossils, as well as charcoal and burnt bones are present. Layer 7\ The fourth travertine, slightly brown, 5—10cm. Layer 8\ Brown sand with bedded clay, as well as breccia, fragments of fossil and some blocks of limestone, 1 8m.

Weidenreich made a detailed in\|depth description of the fossils of Sinanthropus pekinensis (now Homo erectus pekinensis) and pointed out the characteristic features of Homo erectus. He rightly postulated that the adoption of erect posture was achieved first and the transformation of skull followed.Brain enlargement was the motive cause of the change of skull as illustrated by the different sizes of dogs.\;Weidenreich was the first man in history in the first half of the present century attempting to correlate all human fossils yet found in the world with a chart.He believed all fossil humans belonging to one species and could interbreed each other.Man did not originate from one place but several places.He rejected the Australopithecine fossils then found in south Africa playing any post in human evolution and instead suggested a giant phase as the first human period.\;His giant theory of origin of man so far has no fossil evidence.As to the origin of mo\| dern man, the Multiregional hypothesis and the Out of Africa one are now in hot debate.

魏敦瑞对中国猿人(现为直立人北京亚种),化石作了详尽而深入的描述并指出了直立人的典型特征。他正确地推测, 在从猿到人的演化过程中首先是直立姿势的采用, 跟着是头骨的变化, 脑的扩张是头骨变化的动因。本世纪前半叶, 魏敦瑞第一次用一个图将所有已知的人类化石集合在一起, 作系统排列的尝试, 来表示整个人类的演化过程。他相信所有化石人类属于一个种, 能够互相杂交, 人类不是起源于一个地方, 而是起源于几个地方。他反对南方古猿曾经参与人类进化的说法, 代之以认为人类进化的早先各期是巨人阶段, 但是他的巨人理论迄今没有化石的证据。关于现代人的起源, 多地区起源说和非洲起源说目前正在激烈争论之中
