For the past two decades, studies and debates on the modern human origins around the world have attracted attentions to the late Pleistocene human evolution 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 evolution, 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.

Mesial-distal and buccal-lingual dimensions of 1 2.6 hominoid teeth found in Yuanmou of Yunnan Province during the period of 1986 and 1988 have been measured. The statistical analyses of the metric data show that the tooth sizes of Yuanmou hominoid can be divided into big and small two types, and most tooth dimensions display obvious bimodalities in both histograms and 2.dimensional plots. The coefficients of variance (CV) reveal that the CVs of Yuanmou hominoid tooth sizes are within or close to the CV ranges of Lufengpithecus and extant great apes. The comparisons of tooth sizes and their proportions indicate that Yuanmou hominoids have close affinities with Lefeng and Kaiyuan hominoids, and have obvious differences with Gorilla, Chimpanzee and Orangutan. The authors believe that the hominoid fossils found in Yuanmou in the past 10 years represent a single species with highly sexual dimorphism in morphology and this species may have a close evolutionary relationship with the hominoids found in

The development of computer tomography and image processing has made it possible to establish virtual 3D reconstruction and non-invasive dissection of fossil specimens. We used these methods to reconstruct a virtual 3D skull of a Pleistocene cheetah skull from the Tuozi cave, Tangshan, Nanjing, and virtually dissected it for anatomic studies, and measured the volumes of different parts of the endocranium. The endocranium of the cheetah skull has showed that its frontal sinus is beehive-like, the frontal lobe of cerebra is relatively large but the temporal lobe is relatively small, its cerebral sulcus and gyrus are more complicated than those of the domestic cat, similar to those of the domestic dog, but simpler than those of giant panda, pig, cattle and horse. The technology of virtual 3D reconstruction and non-invasive dissection of fossil specimens can extend the morphological study from the exterior to the interior, and it can also help to study fragile specimens and virtually backup rare and precious specimens.

Three early vertebrates (galeaspids Sanqiaspis zhaotongensis liu 1975,Lungmenshanaspis yunnanensis sp. nov., and an undetermined osteolepid ), weredescribed from the Early Devonian of Bianqinggou, Zhaotong District,northeastern Yunnan. It is argued that the fish-bearing formation could be directly correlated with the Posongchong Formation in Guangnan and Wenshan,southeastern Yunnan, and might be named as the Posongchong Formation, rather than the "Cuifengshan Formation". The Posongchong Formation of Bianqinggou yields abundant remains of early vertebrates including galeaspids, antiarchs,petalichthyids and sarcopterygians. Four genera of galeaspids have been described from this formation, i.e., Sanqiaspis (liu, 1975; this paper), Qingmenaspis (Pan & Wang, 1981), Zhaolongaspis (Wang & Zhu, 1994 ), Lungmenshanaspis.

Track fading is a basic phenomenon in track science and has been the source of informa- tion in geosciences. This article summarizes the knowledge of track fading and gives some examples of successful applications of track fading in archaeology, tectonics and geothermal chronology in china. The applications of track fading are classified into 5 modes：（1） mode of complete fading （annealing）; （2. mode of partial fading; （3） use of the dependence of track fading on time and temperature; （4） use of the differences of track fading between coexisting minerals; and （5） use of fading-reduced track length. Track fading mechanisms hints that scientists in geothermal chronology should adopt microprobes for quantitative elemental analysis to determine the detailed chemical compositions of each mineral grain or at least of the grains from each position of geological structures in order that one becomes well aware of the relation between the track fading behavior and chemical compositions of the mineral used.

Large herbivorous mammals from 10 representative Quaternary localities in northeasternchina were studied. The evolution of these animals confirms Pei’s law and Bergmann’s rule. Of thethree global cold periods in the Quaternary, the first and second are not well recorded in the *** temperate period between these is well recorded. Records show that there was a sub-coldperiod (around 2.0 000 yr) during this temperate period. It remains to be confirmed whether thissub-cold period was limited to northeastern china. The third cold period is well recorded in theregion. The fauna in this third period were composed mostly of temperate forms, as well as typicalcold and pro-cold forms.

The Asian interior has the largest mid-latitude arid zone in the Northern Hemisphere,and so has become increasingly attractive for studying the initiation and the past extent of aridiflcation in this *** the enormousness of the Asian interior,it remains unclear how old and extensive the eolian deposits might have been,and what wind regimes have been responsible for the formation of the mid-latitude arid *** we report new eolian records of widespread Tertiary eolian deposits in a region far from the chinese Loess Plateau,the giant Junggar inland basin of northwestern *** results demonstrate that the earliest eolian deposition initiated ca.2. *** interpret that the Tertiary eolian dust in the Junggar Basin was transported by westerly winds,possibly from areas in Kazakhstan;the dust differs from the airborne dust transported by winter monsoon winds from the deserts of Mongolia and northern china that accumulated on the Loess *** results further reveal that the climate pattern,similar to that of the present,has prevailed at least since the latest Oligocene in Central Asia.
