南亚次大陆位于欧亚大陆南部,历来与东南亚和东亚关系密切,是东西方旧石器文化交流的枢纽之一。自旧石器时代早期开始,南亚次大陆就有古人类活动的踪迹,这一地区发现的打制石器遗存数量丰富、面貌多样;石核-石片技术具有本土特征,阿舍利技术、莫斯特技术、石叶技术和几何形细石器技术与欧亚大陆西侧十分相似;细石叶技术可能受到东亚的影响。本文回顾了南亚次大陆打制石器的发现与研究简史,梳理其文化分期和石器工业技术面貌特点,希望能对东西方旧石器文化起源、交流与扩散课题的深入研究有所启发,并为中国以后的旧石器考古研究工作提供一定的参考。
关键词:
The South Asian subcontinent, located south of the Eurasian continent and adjacent to East Asia, has a close relationship with Southeast Asia and China. It has long been a critical pivot of eastern and western Eurasia playing a unique and irreplaceable role in cultural communication and technology diffusion. In this paper, we clarify the research history, chronology and technology of knapped lithics from the South Asian subcontinent, in order to offer more information for further work.
Traces of ancient humans first appeared in the Early Paleolithic, and numerous lithics of different technological characteristics have been discovered since 1863, when Foote RB collected the first hand-axe in Madras, southeast India. Due to some historical reasons, however, there are three main problems in Paleolithic research of the South Asian subcontinent. First, only a few sites have been excavated, with most findings on the surface, which has led to controversies such as the identity of the Soan culture and its relationship to the Acheulian. Second, both the lack and uncertainty of dating data makes the chronology somewhat questionable and thus ambiguous for each stage of the Paleolithic. Third, despite the efforts of several generations of scholars, most archaeological reports of the subcontinent are still scarce, and many lack clear photographs or 3D models for researchers who do not have access to these important materials.
Various lithic technologies are recognized in the South Asian continent. Core-flake technology, including pebble tool and flake tool assemblages from the Early Pleistocene to the Holocene. This is a unique phenomenon because pebble tools such as chopper-chopping tools decrease and finally disappear with the rise of more complicated technologies in most cases. The Acheulian, Mousterian, blade, and geometric microlithic technologies are similar to those in western Eurasian, respectively. Large cutting tools such as hand-axes, cleavers and picks predominate in the Early Pleistocene, whereas geometric microliths are also widely distributed in Terminal Pleistocene and Holocene. Mousterian and blade products are not as common, which might hint at a different role that the subcontinent plays in human dispersal and communication in the early Late Pleistocene. Microblade products, such as minute blades(microblades) and specially prepared microblade cores, might come from East Asia where these products are large in quantity, mature in technique, and clear and complete in a developing sequence.

1 引言
近二十年,随着考古工作逐步开展,中国百色[11]、丹江口[12]、洛南[13]、川西[14]等地发现了许多含手斧的遗址,表明东亚并非一片孤立、落后的地区,旧大陆东西两侧在旧石器时代早期就已经存在人群或技术的交流。同时,内蒙古、新疆等地也陆续发现了莫斯特和石叶技术遗存[15,16]。关于这些旧石器中晚期技术因素的来源与传播路线,部分学者将目光聚焦于“北方路线”[17,18];这一方面是因为欧洲和西亚的石器研究比较详尽,另一方面则是基于北方草原地带地理阻隔较少、便于人类迁徙。另外一些学者结合石制品、基因组学和人类化石的研究认为,早期现代人扩散采用“南方路线”[19,20],南亚次大陆是其中重要的一站。此外,基于青藏高原尼阿底[21]、白石崖[22]、皮洛[14]、邱桑[23]等新发现,有学者提出了“高原丝绸之路”的概念[24],与克什米尔地区相连的青藏高原西部、沟谷纵横的青藏高原东南部,乃至被视为“天堑”的喜马拉雅山脉都可能成为人类迁徙交流的通道[25],青藏高原有着沟通东西与南北的重要功能。
南亚次大陆作为东西方交流的必经之路,对于讨论中国旧石器时代的人类活动历史具有重要意义。然而,受语言、历史和研究传统等因素的制约,国内研究缺乏对其石器材料的系统介绍,旧石器时代人群与文化的交流情况、时间节点和扩散路线仍不明了。本文尝试回顾南亚次大陆打制石器的发现与研究简史、梳理其文化分期和技术面貌,以期对深入研究东西方古人类文化交流有所裨益,为日后中国、尤其是青藏高原的研究工作提供一定的参考。
2 研究简史
受学科发展历史和自然环境制约,南亚次大陆打制石器遗存的发现和研究多集中于印度和巴基斯坦两国,斯里兰卡和尼泊尔也有一些材料见诸报道,不丹、马尔代夫、孟加拉等国则基本缺乏相关信息(图1)2)(2) 图中细石器的概念与东亚细石叶细石器的概念并不一致,详见后文。)。

南亚次大陆打制石器的研究始于19世纪60年代,但早年的工作中,石制品的分类与分期大多没有统一的标准和术语,影响力非常有限。Foote最早将南亚次大陆旧石器时代的文化性质与欧洲旧石器时代早中期的舍利-莫斯特文化(Chellian-Mousteria)对应起来,认为印度旧石器时代缺乏晚期遗存,与新石器时代之间存在一段空白[3]。有的学者提出南亚存在一个旧、新石器时代过渡阶段的中石器时代,以细石器为主要特征[4,5]。20世纪30年代,南亚次大陆的旧石器研究进入了新阶段[26],Cammiade和Burkitt将印度东南部石制品划分为手斧产品、石片石器、石叶-雕刻器-端刮器组合和细石器产品[6]。随后,Todd又划分出手斧、发达手斧和石片石器、石叶和刮削器、石叶-雕刻器、细石器等组合[7]。上述分类虽无明确分期命名,但已有相对明确的时间涵义,这使得南亚次大陆石器技术的年代序列逐渐清晰起来。
表1 南亚次大陆旧石器时代分期表(据Kenndy[30],Korisettar[31],Chauhan[32])
Tab.1
分期Period | 石器特征Characteristics of lithic artifacts | 年代范围Age (kaBP) |
---|---|---|
旧石器时代早期 Lower Paleolithic | 模式I与模式II,石制品类型有大石片、手斧、薄刃斧、砍砸器等。 | 1500-130 |
旧石器时代中期 Middle Paleolithic | 石片石器技术,存在莫斯特技术。石制品类型有石片、勒瓦娄哇石片、刮削器、尖状器、小型化的手斧、钻等。 | 385/114-40 |
旧石器时代晚期 Upper Paleolithic | 以棱柱状石核剥离的两边平行石叶为显著特征,石器包括雕刻器、琢背石叶等。同时开始出现细石器技术产品。 | 40-10 |
中石器时代Mesolithic | 以细石器技术产品为代表。 | 10-6 |
上述分期体系使用了常用术语便于开展研究,但也存在如下问题:
3 石器技术
3.1 石核-石片技术
索安文化发现于20世纪30年代,它是南亚次大陆最具特点的石核-石片技术传统文化,代表了一种不含手斧的石器工业。它在广义上囊括了砾石石器、石片石器、莫斯特技术产品的技术混合体[9],狭义上仅指以砾石石器为代表的砍砸器传统[10]。由于缺乏明确的地层信息和测年数据[32],研究者们对其文化内涵与分期观点不一。de Terra和Paterson认为索安文化包括砍砸器、预制石核、长石片等元素[9],莫维斯将其统一归为砍砸器传统[10],而Stiles则认为所谓的砍砸器传统是调查时采样偏差造成的[47]。之后,学者又按照石制品组合将其分为下层索安(Lower Soanian)、早期索安(Early Soanian)、上层索安(Upper Soanian)和末期索安(Final Soanian),分别对应砾石石器、盘状石核石器、石片石器和勒瓦娄哇技术产品[48],同时包括了模式I与模式III技术。
根据砍砸器的存在,部分学者认为印度中部的Mahedevian和Durkadian砾石石器组合属于奥杜威工业[52]。而另一些学者又以整体数量偏少、技术面貌混杂为由加以反对,认为南亚次大陆石核-石片技术的文化面貌模糊,不能轻易归入奥杜威或克拉克当工业[36],一些曾被认为属于旧石器早期的砾石石器可能属于和平文化(Hoabinhian Culture)和安雅辛文化(Anyathian Culture)等更晚的文化类型[46]。有学者甚至认为“索安文化”并不是一个有效的概念[36]、已属历史话题[30]。目前学界仍保留着“索安文化”这一术语,但其确切的文化面貌尚有待未来新的发现和研究工作进一步厘清。
3.2 阿舍利技术
阿舍利遗存在南亚次大陆分布广泛,它是南亚次大陆旧石器时代早期最具特色的石器遗存。除恒河平原、东北部雨林和半岛最南端外[32],喜马拉雅山区、西北部沙漠、中部河谷、东部高原和南部沿海地区均发现有大量的手斧遗存[57]。然而,与南亚次大陆其他旧石器遗址的问题一样,大部分阿舍利技术遗址缺乏绝对测年数据[36]。在为数不多经过测年的遗址中,最早的可早至1.50 MaBP前后[60],其他则多在0.70~0.40 MaBP的范围内。一些遗址的测年结果还存在争议,如Bori遗址通过K-Ar测年法可至1.38 MaBP[61],但后续的工作并不支持这一结果[62]。值得一提的是,南亚次大陆还存在晚至MIS 6(约130 kaBP)、非常年轻的阿舍利遗存[63]。
3.3 莫斯特技术
3.4 石叶技术
3.5 细石器技术
南亚次大陆的细石器包括几何形细石器和非几何形细石器两大类[72]:前者是该区域细石器的主流产品,以半月形器、梯形器、三角形器等为代表;后者则是一个较为混杂的概念,同时包括细石核、细石叶,以及小石片、端刮器、边刮器等。在东亚地区的研究中,细石器以细石叶、细石核及相关石制品为限,一般不囊括小型石片石器[82,83]。南亚和东亚细石器的概念存在一定差异,细石叶细石器和小型石片石器揭示的文化传播与适应意义也大有不同,在开展地区对比研究时需要格外注意。如斯里兰卡约45 kaBP的Kitulgala遗址[84],原研究者认为的细石器遗存实为脉石英质小型石片石器组合,并非严格意义上的细石器遗存[85],无论是讨论几何形细石器技术或是细石叶细石器技术的扩散都不宜包括此类遗存。
南亚细石器的打制方法主要是硬锤或间接法,台面小或破碎,石器通常是琢背(backed)或斜折(obliquely truncated)修理。细石核可见金字塔形(pyramidal)、长方形(rectangular)、锥形(conical)、亚金字塔形(sub-pyramidal)、亚长方形(sub-rectangular)、亚锥形(sub-conical)等形态[86,87]。细石叶常被有意截断成各种形态,其形状和尺寸的差异可能是由于时代或生计模式不同[81]。原料上,大部分地区以燧石、玛瑙、玉髓等为主要原料,而在斯里兰卡则是脉石英和水晶占主导地位。南亚报道最早的细石器在45 kaBP前后,如印度北部47 kaBP的Dhaba第3地点[75],中部44 kaBP的Mehtakheri遗址[71],东南部38~35 kaBP的Jwalapuram 9遗址[87],东部48~25 kaBP的Kana和Mahadebbera遗址[88]。不过其年代虽早,文化面貌却与东亚细石器存在显著差异,在对比研究时需详细辨析斯里兰卡的细石器遗存多为几何形细石器,从更新世晚期一直延续到全新世[81]。在空间分布上,除了东北部雨林地区之外[81],细石器在河岸、岩石露头地、山麓、沙丘、洞穴、岩厦等各种地貌环境均有所见[89]。有学者认为南亚次大陆西北部沙漠地区的细石器出现很晚,与更早的石器遗存没有太多联系,可能并非本地起源;中部纳尔默达河流域则有非几何形细石器出现早于几何形细石器的现象[90],可能代表了细石器工业内部的发展变化。
石器小型化作为晚更新世期间全球石器共有的显著特点,其起源与扩散问题一直备受关注,许多学者将其与现代人及其复杂化行为、象征性行为等联系在一起[91]。在西方学者的视角下,南亚次大陆细石器的来源大致有以下两种假说[92]:扩散假说(dispersal model)认为掌握几何形细石器技术的非洲现代人群沿海岸线向东迁徙,在距今50 ka前后将该技术带到了南亚[91];适应假说(adaptive model)认为南亚次大陆与非洲的细石器并不相似,且两者存在时间差[93],因此南亚细石器技术是本地人群适应人口增长和环境恶化的产物[72]。事实上,南亚次大陆是东西方旧石器文化交流的枢纽,流动性极高、掌握细石器技术的人群在这一区域可能有着更为复杂的迁徙路线和交流活动。除几何形细石器外,南亚还有特殊的细石叶细石器,这类技术可能受到东亚周边地区人群的影响,其具体扩散路线和时间节点有待进一步研究。
4 讨论与结语
4.1 南亚次大陆打制石器的特点
自19世纪中叶以来,多国学者在南亚次大陆开展石器调查和研究,积累了大量考古材料,涉及诸多重要学术问题。该地区旧石器研究中,系统发掘遗址数量有限、遗址绝对测年数据的缺乏、对采集标本相关研究的可靠性常被质疑[94],术语和范式存在概念不一、阐释不清的现象。因此,总结和梳理南亚次大陆打制石器的研究状况,有助于了解和讨论其石器文化序列及其与周边地区的文化交流。
南亚次大陆的打制石器遗存数量丰富、面貌多样,整体上与旧大陆西侧的石器技术类似。南亚次大陆的石核-石片技术存续时间很长,且分布范围广、特点突出,应当存在自身发展和演化的序列。旧石器时代早期的阿舍利遗存遍布整个南亚次大陆地区,最早的Attirampakkam遗址在年代上与亚洲西部和非洲的早期遗存接近,这或许意味着使用手斧的直立人群体走出非洲后很快就扩散到了这里。旧石器时代中晚期的勒瓦娄哇和石叶技术则有所不同,尽管存在特例[35],但南亚次大陆遗存整体晚于欧洲同类技术的遗存,数量上也不占优势。这一现象与阿舍利技术阶段有显著区别,可能代表该阶段南亚的本土因素更占上风。随后,全球石器技术出现小型化趋势,南亚出现了几何形和非几何形细石器遗存,前者应为旧大陆西侧技术或人群扩散的结果,细石叶细石器则可能受到东亚的影响。
南亚次大陆的石器技术和人类活动呈现出复杂性与多样性,各方学者对莫斯特技术与细石器技术的来源也是各执一词。尽管本土起源说与外来说针锋相对,但南亚次大陆独特的地理位置使它成为人类交流、扩散路途上重要的交汇点,本土与外来因素在这片土地上相互交织,其遗存与文化丰富多元。

4.3 结语
本文通过回顾南亚次大陆百余年来旧石器时代考古的发现与研究发现,南亚次大陆因其特殊的地理位置,在旧石器时代就扮演着旧大陆东西两侧人类沟通的重要作用,文化因素呈现多元交融的特点。南亚次大陆有相对本土的石核-石片工业,阿舍利、莫斯特、石叶技术等与旧大陆西侧近乎同步,而晚期的细石叶技术则明显受到东亚地区的影响。
南亚次大陆紧邻中国,了解、辨析南亚次大陆旧石器时代石器技术的面貌和源流,对于研究东亚地区旧石器时代“西方因素”技术产品的来源和传播过程有重要的参考价值。更加重要的是,南亚次大陆与青藏高原在地理位置更为接近,旧石器时代考古遗存的分布、类型与保存状况也存在相似之处,分析和总结南亚次大陆的材料,对未来在青藏高原地区开展调查和发掘工作,研究喜马拉雅山脉南北古人类活动具有重要的参考价值。

The first Indian Palaeolithic stone implement was found more than 60 years ago in a ballast pit at Pallavaram, a little to the west of the Madras-Trichinopoly road. Since then a large number of stone tools belonging to various prehistoric cultures have been discovered by several keen archaeologists, among whom Bruce Foote deserves special mention.

Mid-Pleistocene Acheulean-like Stone Technology of the Bose Basin, South China
[J].Stone artifacts from the Bose basin, South China, are associated with tektites dated to 803,000 +/- 3000 years ago and represent the oldest known large cutting tools (LCTs) in East Asia. Bose toolmaking is compatible with Mode 2 (Acheulean) technologies in Africa in its targeted manufacture and biased spatial distribution of LCTs, large-scale flaking, and high flake scar counts. Acheulean-like tools in the mid-Pleistocene of South China imply that Mode 2 technical advances were manifested in East Asia contemporaneously with handaxe technology in Africa and western Eurasia. Bose lithic technology is associated with a tektite airfall and forest burning.

The dispersal of Neanderthals and their genetic and cultural interactions with anatomically modern humans and other hominin populations in Eurasia are critical issues in human evolution research. Neither Neanderthal fossils nor typical Mousterian assemblages have been reported in East Asia to date. Here we report on artifact assemblages comparable to western Eurasian Middle Paleolithic (Mousterian) at Jinsitai, a cave site in North China. The lithic industry at Jinsitai appeared at least 47-42 ka and persisted until around 40-37 ka. These findings expand the geographic range of the Mousterian-like industries at least 2000 km further to the east than what has been previously recognized. This discovery supplies a missing part of the picture of Middle Paleolithic distribution in Eurasia and also demonstrates the makers' capacity to adapt to diverse geographic regions and habitats of Eurasia.Copyright © 2017 Elsevier Ltd.

The Initial Upper Paleolithic of Kamenka site, Zabaikal region (Siberia): A closer look at the blade technology
[J].
DOI:10.1016/j.ara.2018.02.004
[本文引用: 1]
In Asia, the Initial Upper Paleolithic refers to blade-based lithic assemblages that display a specific suite of features and date back to the beginning of the MIS3. Previously we reported strong similarities between examples from the Siberian Altai and North Mongolia, but little is known about what generates the variability observed at the assemblage level. The site of Kamenka is particularly relevant to address these issues for several reasons. First, it documents some of the earliest occurrences of the Upper Paleolithic in the Zabaikal region. Second, the fast burial of the archaeological layer and the bone preservation provide groundwork to discuss human subsistence strategies. Third, the dominant raw material sources could be distant and fall outside of the daily foraging radius. Here we give a closer look at the Kamenka A blade assemblage to model the reduction sequences. Our analyses confirm that the blade technology fits a conservative definition of the Initial Upper Paleolithic in Asia. Considering other lines of evidence (such as spatial distribution, or fauna analyses), we discuss the impact of mobility, site function and raw material procurement strategies on the assemblage composition. We conclude that while some of these parameters may affect the tool types and reduction stages represented within the assemblage, the blade reduction method does not show substantial differences between neighboring regions.

The earliest human occupation of the high-altitude Tibetan Plateau 40 thousand to 30 thousand years ago

[本文引用: 1]
The Tibetan Plateau is the highest and one of the most demanding environments ever inhabited by humans. We investigated the timing and mechanisms of its initial colonization at the Nwya Devu site, located nearly 4600 meters above sea level. This site, dating from 40,000 to 30,000 years ago, is the highest Paleolithic archaeological site yet identified globally. Nwya Devu has yielded an abundant blade tool assemblage, indicating hitherto-unknown capacities for the survival of modern humans who camped in this environment. This site deepens the history of the peopling of the "roof of the world" and the antiquity of human high-altitude occupations more generally.Copyright © 2018 The Authors, some rights reserved; exclusive licensee American Association for the Advancement of Science.

Earliest parietal art: hominin hand and foot traces from the middle Pleistocene of Tibet

[本文引用: 1]
At Quesang on the Tibetan Plateau we report a series of hand and foot impressions that appear to have been intentionally placed on the surface of a unit of soft travertine. The travertine was deposited by water from a hot spring which is now inactive and as the travertine lithified it preserved the traces. On the basis of the sizes of the hand and foot traces, we suggest that two track-makers were involved and were likely children. We interpret this event as a deliberate artistic act that created a work of parietal art. The travertine unit on which the traces were imprinted dates to between ∼169 and 226 ka BP. This would make the site the earliest currently known example of parietal art in the world and would also provide the earliest evidence discovered to date for hominins on the High Tibetan Plateau (above 4000 m a.s.l.). This remarkable discovery adds to the body of research that identifies children as some of the earliest artists within the genus Homo.Copyright © 2021 Science China Press. Published by Elsevier B.V.

Stimulated cells and cancer cells have widespread shortening of mRNA 3’-untranslated regions (3’UTRs) and switches to shorter mRNA isoforms due to usage of more proximal polyadenylation signals (PASs) in introns and last exons. U1 snRNP (U1), vertebrates’ most abundant non-coding (spliceosomal) small nuclear RNA, silences proximal PASs and its inhibition with antisense morpholino oligonucleotides (U1 AMO) triggers widespread premature transcription termination and mRNA shortening. Here we show that low U1 AMO doses increase cancer cells’ migration and invasion in vitro by up to 500%, whereas U1 over-expression has the opposite effect. In addition to 3’UTR length, numerous transcriptome changes that could contribute to this phenotype are observed, including alternative splicing, and mRNA expression levels of proto-oncogenes and tumor suppressors. These findings reveal an unexpected role for U1 homeostasis (available U1 relative to transcription) in oncogenic and activated cell states, and suggest U1 as a potential target for their modulation.

Wave-particle duality is an inherent peculiarity of the quantum world. The double-slit experiment has been frequently used for understanding different aspects of this fundamental concept. The occurrence of interference rests on the lack of which-way information and on the absence of decoherence mechanisms, which could scramble the wave fronts. Here, we report on the observation of two-center interference in the molecular-frame photoelectron momentum distribution upon ionization of the neon dimer by a strong laser field. Postselection of ions, which are measured in coincidence with electrons, allows choosing the symmetry of the residual ion, leading to observation of both, gerade and ungerade, types of interference.

It has been argued recently that the initial dispersal of anatomically modern humans from Africa to southern Asia occurred before the volcanic “supereruption” of the Mount Toba volcano (Sumatra) at ∼74,000 y before present (B.P.)—possibly as early as 120,000 y B.P. We show here that this “pre-Toba” dispersal model is in serious conflict with both the most recent genetic evidence from both Africa and Asia and the archaeological evidence from South Asian sites. We present an alternative model based on a combination of genetic analyses and recent archaeological evidence from South Asia and Africa. These data support a coastally oriented dispersal of modern humans from eastern Africa to southern Asia ∼60–50 thousand years ago (ka). This was associated with distinctively African microlithic and “backed-segment” technologies analogous to the African “Howiesons Poort” and related technologies, together with a range of distinctively “modern” cultural and symbolic features (highly shaped bone tools, personal ornaments, abstract artistic motifs, microblade technology, etc.), similar to those that accompanied the replacement of “archaic” Neanderthal by anatomically modern human populations in other regions of western Eurasia at a broadly similar date.
