    Nanjing, the Homo sapiens erectus fossil site, is a geographical intermediary between Zhoukoudian, North China, and Sangiran, Indonesia. Fortunately, the Nanjing 1 cranium preserves facial skeleton, which is comparable with those from Zhoukoudian and Sangiran. To examine the geographic variation of Homo sapiens erectus in China, a comparison of Nanjing 1 with Sangiran 17 and Zhoukoudian 11 in facial morphology is made in this paper. The comparison shows that Nanjing 1 resembles Zhoukoudian 11 in many features, including smaller face, flat infraorbital region, flatter upper face, less massive supraorbital torus, mesoconchy orbit, obtuse angle shape of inferolateral margin of the orbit, clear expression of the malar incisure, and high base of zygomatic process of maxilla. However, Nanjing 1 resembles Sangiran 17 in other features. These features include broad face, the supraorbital torus projecting more medially than laterally in superion view, relatively horizontal orientation of the inferior border of the supraorbital torus, distinct internasal keeling, tented shape of saddle in transverse section, eversion of the low border of the zygomatic, a more laterally situated malar tubercle, and a higher zygomatic bone. Nanjing 1, as Hexian does, is a morphological intermediary between Zhoukoudian and Sagiran, and suggests a geographic variation between North and South Homo sapiens erectus in China. The morphology of Nanjing 1 supportsthe contention that "There may have been a gradient in morphology running from the north to the south of East Asia"( Wolpoff, 1999) .

    In 1933, Black et al subdivided the deposits in the cave into 3 different regions: the Main Deposit, the Lower Fissure and the Kotzetang. From then on, however, some controversies regarding the correlation of different strata in the three regions have arisen. Specifically, the first skull of Peking Man, which was definitely unearthed from the Lower Fissure, has always been virtually located in two different layers of the Main Deposit.
    Lin Shenglong recently published a paper proposing the stratum bearing the first skull of Peking Man be correlated with layer 11 of the Main Deposit. However, based mainly on the original reports in the 1920s and 1930s, we have readily come to an otherwise conclusion by employing the principles of stratigraphy. As a result, we tentatively propose here that it would be even more appropriate if the SE stratum was correlated with layer 10 of the Main Deposit.

    Zhang Shuang-quan and Xu Qin-qi emphasize that the stratum bearing the first skull ( Locus E skull) of Peking Man is the red sandy clay, so it should correspond to the Layer 10 of the Main Deposit. The discoverer of the Locus E skull, Pei WC and the first researcher of it, Black reported that the sediment adhered to Locus skull is travertine, so the stratum bearing Locus E skull belongs to the Travertine Layer. With the Layer 10 of the Main Deposit as the frame of reference, the stratum of Lower Cave should correspond to the Layer 11 of the Main Deposit ( Table 1) .

    23 human skulls excavated from 11 ancient tombs in Kizil, Baicheng county, Xinjiang, have been measured and observed. Some indexes and angles were calculated. The statistics combined with other 25 ancient groups located nearby and Centra-l Asia were compared directly and analyzed with Cluster Analysis and Principle Component Analysis. All results have been shown that the ancient Kizil population belong to Caucasoid, they have close relation to the Indo-Afghan racial type of the east branch of the Mediterranean.

    The HeathCarter somatotyping method was used to study the adult somatotypes among 494 Bouyei individuals (259 males; 235 females) in Guizhou province. This comparison of somatotypes was between northern and southern nationalities. Results of this research were : (1) The mean somatotype for both sexes was endomesomorphic, where males and females ranged between 3.0-5.3-2.4and 4.3-4.9-1.9 respectively. (2) With age in males, the value of endomorphic traits hardly changed, mesomorph increased and ectomorph decreased and generally changes of male somatotypes were small. (3) With age in females, endomorphic and ectomorphic features increased but mesomorphic decreased.

    A survey of somatoscopic and anthropometric traits of 773 adults (379 males and 394 females) of Bouyei nationality between ages 20 and 55 years living in Guizhou was carried out in July 2003. Twenty2eight observations and 64 measurements were made on this sample of parents and grandparents.
    The results of the survey are summarized as follows:
    The average stature of Bouyei nationality males is 1 602142 mm, and females is 1 504104mm. In both of sexes ,arm span is longer than that stature. Most of the individuals belong to a mesocephalic body shape ,mesoproscopy for males, euryproscopy for females ,platyrrhiny. The stature of these people is sub2medium and short. The Bouyei nationality clearly belongs to the South Asian type of the Mongoloid race.
    On a comparative basis of the Bouyei with 29 other minorities groups living in southern China, the physical character of the Bouyei is most closely related to the Zhuang in Guangxi, Li in Hainan, and is similar to those of the Tujia, Yao in Hunan, and Yi in Guangxi. It is remotely related to the Dong in Hunan, Maonan in Guizhou, and the Baiku Yao living in Libo county of Guizhou and Nandan county of Guangxi.

    Using PCR-STR, the polymorphism distributions of nine STR loci were investigated in 183 unrelated Mulao individuals from Guangxi Province, and as part of this work the genetic database of Mulao population was established. There were 70 STR alleles and 207 genotypes were observed in the nine STR of the Mulao ethnic group with statistical frequencies ranging from 0.002 7~ 0.530 1 and 0.0055~ 0.3388 respectively. The average heterozygosity was 0.729 8; polymorphism information content was 0.701 6; accumulative discrimination power was 0.999 999999, and the probability of paternity exclusion was 0.999 098. The result of a comparison between the Mulao and other ethnic groups showed that there were statistically significant differences between the Mulao and Miao, Hui minorites of Guangxi and the minorities of Yunnan and North China, but with there was no difference between the Mulao and Guangxi Zhuang and Hunan Han minorities. The obtained data can be useful for its application to genetics, forensic science and anthropology.

    Objective: To explore the applicability and rationale of principle component analysis based on the averaged covariance matrix for analyzing human populational genetic structure. Methods: Based on the structure of gene frequency matrix, we showed differences of eigenvalues, eigenvectors, and their effect in reducing the dimensionality between the standardized correlation matrix principle component analysis and the averaged covariance matrix principle component analysis. To validate and compare their use and rationale in human population genetics, we analyzed the genetic structure of HLA-A locus in 26 Chinese Han populations using both standardized correlation matrix principle component analysis and averaged covariance matrix principle component analysis methods. Results: The principle component of standardized correlation matrix does not represent the variance weight of gene frequency matrix. Instead it represents the correlation weight between the genes. The principle component of averaged covariance matrix not only reflectsthe variance weight of gene frequency matrix, but also identifies correlation weight between the genes in gene the matrix. From analyzing the genetic structure of HLA - A locus in 26 Chinese Han populations using the different two methods, we discovered that the averaged covariance matrix principle component analysis is better than the standardized correlation matrix principle component analysis in reducing the dimensionality of gene frequency matrix. And using the principle method in reducing covariance matrix, the genetic structure of HLA-A locus in Chinese Han populations can be explained correctly. Conclusion: carry out the principle component analysis of human population genetic structure, one should calculate the PC using averaged covariance matrix rather than the standardized correlation matrix.

    Animals remains discovered at the Guanzhuangping site in theYangtze River Three Gorges area belong to the Neolithic, Eastern Zhou and Ming Dynasty periods. Significant Neolithic faunal remains include Ailuropoda melanoleuca, Capricornis sumatraensis kanjereus and Equus przewalskii. Among them Capricornis sumatraensis kanjereus is the latest record of this kind of animal in China, whereas Bos Taurus dated to the Ming Dynasty was introduced from other region. The general feature of the faunal remains from the Guanzhuangping site shows that there was a natural landscape with the high-mountain and valley climate from the Neolithic to the Ming Dynasty. The barranca is dominated by a damp and hot forest climate, while in the peak area, there is a rather natural environmental change in terms of climate and vegetation. Faunal remains from the site also indicate that ancient residents had a strong reliance on wild animal resources as shown by the quantity of associated buried wild animal jaws dating to the Neolithic. A mandible of Ailuropoda as part of a burial is first reported here.

    Post-conflict behavior has been reported in most of non-human primates. Through studies of Old World monkeys and great apes, primatologists have focused on reconciliation behavior as an early stage of post-conflict behavior, but other post-conflict behaviors such as redirected aggression consolatory behaviors and substitute reconciliation have also been noted in recent years. Nowadays, the PC2MC method is adopted in most post-conflict behavior work and many studies indicated that different species have different post-conflict behavioral patterns. Dominance style, kin relationship, rank distance and other factors can influence post-conflict behaviors. Primatologists have also found that different post-conflict behaviors have different functions and have put forward various hypothesese, such as social-cognition hypothesis, social-constraints hypothesis and valuable relationship hypothesis to account for some certain post-conflict behavior.
