Encounter between Present Female Characters and Neolithic Inscribed Symbols Prior to Oracle-bone Inscriptions

Inscribed symbols of Neolithic Age were sometimes suspected to be initial writing prior to developed writing system. The earliest developed writing system in China was Oracle-bone inscriptions (OBIs) of Bronze Age and researchers have long sought its predecessor. Here, we reported that two continuous symbols on a stone ax of Neolithic Liangzhu culture found their identical duplicates in a unique writing system on brocade belts woven by present women in Shanghai suburb. Women in this group duplicated the hereditary text for weddings only once each generation in the past, and they can still interpret these two characters, implying that the two identical Liangzhu symbols may have the similar meanings. The meanings and patterns are both similar to those in OBIs, suggesting that Liangzhu symbols might be one of the predecessors of OBIs. Integrating philology, genetics, linguistics, and folklore, we discussed that special small population may inherit both the genetic structure and convert culture for extremely long time, such as this population in southern Shanghai.

Have We Been Barking up the Wrong Ancestral Tree? Australopithecines Are Probably Not Our Ancestors

The dominant paradigm regarding human evolution since the split with Pan considers australopithecines as hominins, i.e., the closest relatives and/or direct ancestors of Homo. Historically, this paradigm started from the assumption that the Homo/Pan/Gorilla last common ancestor was a knuckle-walking ape that evolved into the fully upright (orthograde), obligate bipedal genus Homo, whereas Pan and Gorilla remained knuckle-walkers. Obligate terrestrial upright bipedalism, unique for our species, is an odd locomotor behaviour for a primate. Therefore, it had become generally accepted that a cooler and drier African climate had caused deforestation, which had forced our ancestors to develop upright bipedalism as an adaptation to living on open grassland savannah. This view, already held by Lamarck and Darwin, appeared most parsimonious in the almost complete absence of fossils. The discovery in the 20th century of australopithecine fossils, bipedal apes with small brains, in open country in southern and eastern Africa corroborated the savannah paradigm. Therefore, australopithecines are considered hominins. However, it is now recognized that most australopithecines instead lived in a mosaic of forests, grasslands and wetlands, and better knowledge of their fossils clearly indicates that they possessed several climbing adaptations. Moreover, none of the extinct ape species older than Australopithecus and Paranthropus for which postcranial remains have been described (e.g., Morotopithecus, Sahelanthropus, Orrorin, Ardipithecus) were knuckle-walking. On the other hand, upright posture/gait is already present to different degrees even in Miocene apes. Moreover, the notion that hominoid orthogrady is a primitive characteristic is corroborated by the growing consensus that knuckle-walking is not a primitive trait but has evolved in parallel, independently in both Pan and Gorilla. Consequently, it is possible that australopithecines are not transitional between a semi-erect ancestor and upright bipedal humans, but to the contrary, are intermediate between a more upright ancestor and extant semi-erect African apes. In summary, hypotheses that attempt to explain how a semi-erect Homo/Pan last common ancestor transitioned into the bipedal australopithecines as an adaptation to life on the savannah appear to be ill-conceived and moreover seem to have been superfluous from the very start. We review the numerous similarities between australopithecines and extant African apes, suggesting that they are possibly not hominins and therefore not our direct ancestors. We suggest that we may have been barking up the wrong ancestral tree, for almost a century.

Where Do Chinese Doublets Come From?—The Doublets from Prehistory to the Era of the Book of Poetry

The earliest writing in China is the oracle bone inscriptions of the Shang Dynasty, which records early Chinese, also known as oracle bone Chinese, which are all monosyllabic-words (1300 BC). In the Bronze Inscriptions of the Western Zhou Dynasty and later handed down documents, doublets appear (beginning in 1046 BC). At present, the philological academy believes that the doublets recorded with two Chinese single-characters come from reduplication of two single-character symbols, but there is no complete argument and reliable evidence. This article, by using the opposite method of argument, reversely assumes that the single-characters (monosyllabic words) come from doublets and tries to demonstrate it. The article proves the truth of the origin of doublets based on the word distribution and semantic correspondence between doublets and single-characters in “the Book of Poetry”, that is, doublets are the source and single-characters are flows. Among them, 39.66% of the doublets have no corresponding single-characters, and they are the characters created to record doublets; 41.92% of the meanings of doublets have nothing to do with the meanings of single-characters, which proves that the doublets does not come from the combination of single-characters; 12.46% of the meanings of doublets are interpreted as the meanings of single-characters, which are the subjective errors of later generations of interpreters; the remaining 5.66% are only associated with proclitics and enclitics rather than single-characters. Finally, the article proposes that doublets originate from a unique mechanism of expressive morphology, which is a new type of etymological theory outside the morphological grammar system, and can create various polysyllabic ideophones, including the onomatopoeia or mimetic words. The article proves that a language begins with the creation of words. In the prehistoric period before the oracle bone inscriptions, Chinese ancestors had invented a large number of distinctive doublets (AA), couplets (AB) and other polysyllabic words (xA, or ABB, ABA’B), or ideophones. Due to the difficulty of writing, the doublets were hidden in spoken language for hundreds of years. It was not until the time of “Book of Poetry” and “Book of History” in the bronze inscriptions of the Western Zhou Dynasty that it entered the history and has continued to this day. Doublets are the earliest Chinese words and the beginning of Chinese civilization.

The Future of Artificial Intelligence Will Be “Next to Normal”—A Perspective on Future Directions and the Psychology of AI Safety Concerns

This paper introduces the AI “next to normal”-thesis, suggesting that as Artificial Intelligence becomes more ingrained in our daily lives, it will transition from a sensationalized entity to a regular tool. However, this normalization has psychosocial implications, particularly when it comes to AI safety concerns. The “next to normal”-thesis proposes that AI will soon be perceived as a standard component of our technological interactions, with its sensationalized nature diminishing over time. As AI’s integration becomes more seamless, many users may not even recognize their interactions with AI systems. The paper delves into the psychology of AI safety concerns, discussing the “Mere Exposure Effect” and the “Black Box Effect”. While the former suggests that increased exposure to AI leads to a more positive perception, the latter highlights the unease stemming from not fully understanding its capabilities. These effects can be seen as two opposing forces shaping the public’s perception of the technology. The central claim of the thesis is that as AI progresses to become normal, human psychology will evolve alongside with it and safety concerns will diminish, which may have practical consequences. The paper concludes by discussing the implications of the “next to normal”-thesis and offers recommendations for the industry and policymakers, emphasizing the need for increased transparency, continuous education, robust regulation, and empirical research. The future of AI is envisioned as one that is seamlessly integrated into society, yet it is imperative to address the associated safety concerns proactively and not take the normalization effects take ahold of it.

Fine-scale Genetic Structure of Geographically Distinct Patrilineal Lineages Delineates Southward Migration Routes for Han Chinese

The Han Chinese (HAN) represent the world’s largest ethnic group, and their genetic structure has been the focus of numerous studies. Yet previous studies failed to draw out finer population stratification of patrilineal HAN, due to limitations in sample size and genetic marker density. This essay employs a Y-haplogroup frequency dataset from virtually whole China aiming to draw out a detailed genetic structure of the patrilineal HAN. We provide an overview of the Y chromosome haplogroup distributions, and find that the patrilineal HAN can be divided into five geographic subgroups. Analysis of Molecular Variance (AMOVA) provided further support for the five-substructure model. By comparing patrilineal and matrilineal descent, we revealed stronger geographical aggregation for patrilineal HAN. Moreover, populations with patrilineal descent showed lower levels of haplogroup diversity (HD) compared to those with matrilineal descent, suggesting potential population bottleneck of patrilineal HAN. The larger HD among northern patrilines verified historical migration of HAN from north to south, which validated by neighbor joining tree (NJ-tree). Overall, we speculate the southward migration routes for Han Chinese, and the HAN south of the Nanling Mountains may have entered via the middle reaches of the Yangtze River, rather than via eastern coastal provinces.

Human Mobility in the Central and Eastern Mediterranean during Hellenistic and Roman Times: The Potential and Limitations of Bioarchaeological Research

This paper offers a review of bioarchaeological research on human mobility during the Hellenistic and Roman period in the Central and Eastern Mediterranean. This period was marked by significant connectivity amidst the establishment of major political entities. The paper begins with an overview of bioarchaeological methods used to study past mobility, including biodistance, isotopic and ancient DNA analyses. It then examines published studies that have utilized these methods to explore mobility during the Hellenistic and Roman periods. The paper concludes by critically assessing the current research limitations and proposing directions for future studies. These suggestions emphasize the importance of conducting additional research to investigate human mobility in neglected areas, as well as at different temporal and spatial scales. Integrating mobility data with other sources of evidence, such as historical accounts, paleoenvironmental data and osteobiographic information is another important future direction of research. Finally, relevant research should be more theoretically informed and its contemporary implications should be effectively communicated within and beyond the academic community. An enhancement of our understanding of the nature and impact of mobility is crucial in today’s society, where misconceptions linking immigration to the decline of the Roman Empire can perpetuate biases against contemporary mobility. 

An Extremely Long Span of the Sun-Earth Pattern in the History of China

Chinese people believe that they are descendants of the prehistory Emperors Yan and Huang, while Yan (hot/red) and Huang (yellow) are the colors of the sun and earth. In the Dahecun style of Yangshao Culture archaeological culture of the legendary Yan and Huang’s period, the patterns of the sun and earth were frequently painted on the religious potteries, implying that the paired symbols might refer to the two emperors. However, the same paired pattern appeared in Shangshan Culture much earlier than Yangshao, indicating that the worship of Sun-Earth might have a quite long history prior to the two emperors. The pattern was inherited in the populations of China till today. The Jade Bi-Cong group of late Neolithic and early Bronze Age China also showed the same meanings and shapes. We found that the Sun-Earth pattern was quite common on the traditional brocade belts woven in the countryside around Shanghai. The origin of the sun shape was easy to understand, while that of the earth shape, a cross with or without an outline square, was hard to trace. Recent archaeological discovery in Shangshan Culture of a kind of yellow pyramid stone provided a new clue to the origin of earth symbol.

Disentangling Human Nature: Environment, Evolution and Our Existential Predicament

Throughout our entire evolutionary history, the physical environment has played a significant role in shaping humans’ subsistence adaptations. As early humans began to colonise novel biomes and construct ecological niches, their behavioural flexibility appeared as an unquestionable fact. During the Late Pleistocene-Holocene transition, the shift from foraging to farming radically altered ecosystem services, resulting in increased exposure to zoonotic pathogens and the emergence of structural inequalities that pervade our current human condition in the Anthropocene epoch. The article seeks to use an anthropological biosocial analysis to explore the diverse evolutionary paths humans have taken, which in turn shape their relationships with the natural world. Given the enigmatic nature of human behavior, it is essential to examine it holistically to understand how different subsistence patterns (e.g., intensive agriculture, foraging, and horticulture) have influenced resilience and adaptation to environmental challenges.utf-8

Human Behavioral Ecology: Opportunities for Theoretically Driven Research on Human Behavioral Variation in China

Human behavioral ecology is an evolutionary framework that attempts to understand how adaptive human behavior maps on to variation in social, cultural, and ecological environments. It emerged as a coherent framework in the United States and the U.K. in the 1980s and has flourished as an explanatory framework ever since. The concentration of HBE scholarship in English-speaking countries has led to missed opportunities to engage other partners in testing and expanding human behavioral ecological models of human behavioral and life history variation. In this review, we provide a brief review of human behavioral ecology and describe opportunities for related scholarship in the Chinese context. We introduce human behavioral ecology holistically, including its history, methodological frameworks, pet topics, and recent integration with related fields, with a special emphasis on its recent integration with Chinese social, archaeological, and life sciences scholarship. We address potential criticisms of human behavioral ecology and how to ensure a robust and careful application of human behavioral ecology principles in the study of human behavior in China, past and present. We conclude with excitement as the remarkable variation in the Chinese behavioral landscape offers unparalleled opportunities for innovative and integrative studies.utf-8

Efficient Communication, the Lexicon, and Grammar

The driving forces behind language variation and change have long been a subject of debate. One prominent approach takes a functionalist perspective and posits that the need for efficient communication shapes lexical and grammatical patterns. This paper reviews five recent studies that offer further support for the plausibility of the communicative efficiency principle while also providing new insights into other factors that contribute to efficient linguistic structures. The key findings from these studies can be summarized as follows: (1) the principle of communicative efficiency offers plausible explanations for both lexical and grammatical phenomena, addressing both synchronic variations and diachronic changes in language evolution; (2) linguistic systems achieve efficiency through multiple mechanisms such as creation bias and selective pressures favoring efficient communication; (3) in addition to communicative efficiency, language evolution is also shaped by language history, with existing structures influencing subsequent ones. By synthesizing these studies, this paper underscores the efficiency account as a plausible and inclusive explanatory framework. It also stresses the need to rigorously delineate the role of communicative efficiency in language evolution, cautioning against automatically conflating the presence of efficient structures with intentional optimization for communicative goals.utf-8

Genetic Insights into Ancient Kinship and Human History: Methods, Applications, and Implications

Recent advances in ancient DNA analysis have transformed our understanding of kinship and underlying social structures in past populations. The application of next-generation sequencing technologies has enabled researchers to reconstruct the genetic makeup of ancient individuals with unprecedented precision, providing new insights into lineage, ancestry, and social organization. Ancient DNA evidence has revealed a wide range of kinship systems, including patrilineal and matrilineal descent, consanguineous marriages, female exogamy, and family-based burial practices. These findings underscore the complexity of human social relationships and the dynamic interactions between genetic inheritance, cultural traditions, and environmental factors in ancient societies. By examining case studies across different geographic and temporal contexts, this review highlights the transformative potential of ancient DNA in deciphering past human relationships. However, it also addresses key ethical concerns, including the importance of respecting cultural sensitivities and avoiding overly deterministic interpretations of genetic data. The integration of genetic evidence with archaeological and anthropological perspectives enables a more comprehensive reconstruction of ancient social systems, moving beyond simplistic genetic determinism to appreciate the intricate interconnections between biology, culture, and identity.utf-8

Maxillary Molar Enamel Dentine-Junction Shape Differences between Krapina Neanderthals and Modern Humans

Archaic and modern humans differ in a range of craniodental features. From a taxonomic and phylogenetic perspective, it is essential to distinguish between species accurately through detailed morphological characterizations. This study analyzes the size and shape variation of the enamel-dentine junction (EDJ) of upper molars from two hominin species, early Neanderthals from Krapina (N = 13) and mid-Holocene European modern humans (N = 14), to assess the extent of their endostructural morphological differentiation. The EDJ was obtained through microtomographic scans of each molar using segmentation procedures. Three-dimensional landmarks semilandmarks and 3D geometric morphometric methods, were employed to investigate EDJ size and shape variation through univariate (t-test), multivariate exploratory, and classification methods (PCA and LDA). The results indicate that the shape of the EDJ and cervix of M² differentiates Krapina Neanderthals from mid-Holocene European modern humans with a high degree of accuracy (~85%). Furthermore, EDJ size and dental nonmetric traits expressed in this structure provide additional information that is useful for distinguishing between the two species. Compared to modern humans, Krapina Neanderthals exhibit reduced dental diversity. From an endostructural perspective, this study provides additional insights into early Neanderthals’ morphological diversification relative to modern humans, which is valuable for studying middle and late Pleistocene hominin evolution.utf-8
