Periodicity of Retzius lines is a key factor in dental development. In this study, we examined the periodicity of Retzius lines in fossil Pongo from South china using polarized light microscope observation of dental ground sections. The periodicities all of the 15 teeth were 9 d. Comparisons of periodicity were made with extant primates, fossil apes and hominins. Periodicity of fossil Pongo from South china was relatively long but fell within the variation of extant Pongo, Gorilla and modern {2., and longer than periodicity of Pan and other extant primates. Fossil Pongo from South china was similar to Lufengpithecus and Sivapithecus, shorter than Gigantopithecus and longer than European and African fossil apes and most early hominins in periodicity. Generally, the periodicities of Asian large-body fossil apes were longer than the periodicities of European and African large-body fossil apes in Miocene. Difference among species and trend of evolution in periodicity were analyzed and discussed. We found that periodicity might gradually increase from Proconsul in early Miocene to several fossil apes in Miocene and then Gigantopithecus in Pleistocene. In addition, this study made correlate analysis between periodicity and body mass respectively in males and females of six extant apes and five fossil apes, and found that periodicity positively correlated with body mass.

During 2.07-2.08 excavations at the Lingjing site near Xuchang,Henan Province,dated back to around 100-80 ka ago,a large quantity of mammalian fossil remains were recovered along with a remarkable cluster of Early Modern human(EMH) skull fragments in *** some of those animal bones were probably modified into tools.A use-wear analysis was carried out to examine the functions of modified bone *** results suggest that Lingjing bone tools were used for drilling,penetrating,and scraping animal substances,and that some might have been hafted during the *** study confirms that early existence ofintentionally-modified bone tools at human occupations of the early Late Pleistocene in northern *** discovery suggests making and use of bone tools were inevitably a part of early human behaviors and cultural development,as such of stone tools.

Chipped-stone "adze-shaped objects" (ASOs) were identified from a few Upper Palaeolithic sites in northern china. Its morpho- logical form resembles to ground-stone type-specific adze, but the function of the ASO has never been assessed. The objective of this study is to investigate the use function of this particular tool type recovered from the Hutouliang site in the Nihewan Basin of northern china. In this study, the lithic use-wear analysis is applied to examining microscopically edge-damages and sur- face-rounding of the tools in order to assess how they were employed. The result suggests that the ASO might have been used as woodworking tools with a hafted shaft, providing evidence for the appearance of the earliest hafted chipped-stone adzes prior to 10000 years ago in northern china. This study also demonstrates that the use-wear technique is an innovated and effective analytic appraoch to the study of stone tool functions that has been conventionally treated by typo-technological analyses. Stone tool use-patterns revealed by use-wear evidence would shed new insights on prehistoric adaptive strategies of modern human in northern china.

In this paper, cut marks on the long bones of class Ⅱ sized animals in the Ma'anshann site are studied. Based on the location and frequencies of the long bone cut marks, the distribution characteristics are analyzed as follows: (1) cut mark frequencies in the lower layer (LL) are much higher than those of the upper; (2. in the LL cut mark frequency of the upper limbs is the highest, and that of the middle and lower limbs is lower and the lowest; (3) In the upper layer (UL) the cut mark frequency, does not spread as orderly as in the LL. The data are compared to those of the experiment and it is demonstrated that values of the LL all fall into the experimental 95% confidence intervals, and the cut mark frequencies of the upper, middle and lower limbs coincide with those of the experiment; while the values of the UL are much lower, of which, those of the humerus, femur and radius are out of the intervals, and the frequencies of the upper, middle and lower limbs are far more different from those of the experiment. It implies that the earlier hominids (of the LL) defleshed the limbs of the class Ⅱ sized animals with stone tools more completely than the later hominids. With the evidence of burning marks, it is suggested that the difference on the roasting behaviors derived the cut mark difference of the Ma'anshan UL and LL.

This paper reviews a large number of genes under positive Darwinian selection in modern human populations, such as brain development genes, immunity genes, reproductive related genes, perception receptors. The research on the evolutionary property of these genes will provide important insight into human evolution and disease mechanisms. With the increase of population genetics and comparative genomics data, more and more evidences indicate that positive Darwinian selection plays an indispensable role in the origin and evolution of human beings. This paper will also summarize the methods to detect positive selection, analyze the interference factors faced and make suggestions for further research on positive selection.

The retrieval of DNA from ancient human specimens is not always successful owing to DNA deteriora-tion and contamination although it is vital to provide new insights into the genetic structure of ancient people and to reconstruct the past history. Normally, only short DNA fragments can be retrieved from the ancient specimens. How to identify the authenticity of DNA obtained and to uncover the information it contained are difficult. We employed the ancient mtDNAs reported from Central Asia (including Xin-jiang, china) as an example to discern potentially extraneous DNA contamination based on the updated mtDNA phylog-eny derived from mtDNA control region, coding region, as well as complete sequence information. Our results demon-strated that many mtDNAs reported are more or less prob-lematic. Starting from a reliable mtDNA phylogeney and combining the available modern data into analysis, one can ascertain the authenticity of the ancient DNA, distinguish the potential errors in a data set, and efficiently decipher the meager information it harbored. The reappraisal of the mtDNAs with the age of more than 2.00 years from Central Asia gave support to the suggestion of extensively (pre)historical gene admixture in this region.

For the past two decades, studies and debates on the modern human origins around the world have attracted attentions to the late Pleistocene human {2. and formation of modern human populations, and some controversial hypotheses and problems have been proposed. In the present paper, some problems on the late Pleistocene human {2., and the formation and differentiations of modern human populations in china are studied with a brief description and comments on the research advances in this field.
