Genetic genealogy provides crucial insights into the complex biological relationships within contemporary and ancient human populations by analyzing shared alleles and chromosomal segments that are identical by descent to understand kinship,migration patterns,and population dynamics.Within forensic science,forensic investigative genetic genealogy(FIGG)has gained prominence by leveraging next-generation sequencing technologies and population-specific genomic resources,opening useful investigative avenues.In this review,we synthesize current knowledge,underscore recent advancements,and discuss the growing role of FIGG in forensic genomics.FIGG has been pivotal in revitalizing dormant inquiries and offering genetic leads in numerous cold cases.Its effectiveness relies on the extensive single-nucleotide polymorphism profiles contributed by individuals from diverse populations to specialized genomic databases.Advances in computational genomics and the growth of human genomic databases have spurred a profound shift in the application of genetic genealogy across forensics,anthropology,and ancient DNA studies.As the field progresses,FIGG is evolving from a nascent practice into a more sophisticated and specialized discipline,shaping the future of forensic investigations. 展开更多

Purpose:This study aims to construct new models and methods of academic genealogy research based on bibliometrics.Design/methodology/approach:This study proposes an academic influence scale for academic genealogy,and introduces the w index for bibliometric scaling of the academic genealogy.We then construct a two-dimensional(academic fecundity versus academic influence)evaluation system of academic genealogy,and validate it on the academic genealogy of a famous Chinese geologist.Findings:The two-dimensional evaluation system can characterize the development and evolution of the academic genealogy,compare the academic influences of different genealogies,and evaluate individuals’contributions to the inheritance and evolution of the academic genealogy.Individual academic influence is mainly indicated by the w index(the improved h index),which overcomes the situation of repeated measurements and distortion of results in the academic genealogy.Practical implications:The two-dimensional evaluation system for the academic genealogy can better demonstrate the reproduction and the academic inheritance ability of a genealogy.Research limitations:It is not comprehensive to only use the w index to characterize academic influence.It should also include scholars’academic awards and academic parttimers and so on.In future work,we will integrate scholars’academic awards and academic part-timers into the w index for a comprehensive reflection of scholars’individual academic influences.Originality/value:This study constructs new models and methods of academic genealogy research based on bibliometrics,which improves the quantitative assessment of academic genealogy and enriches its research and evaluation methods. 展开更多

The paper shows that the story about the origin of Armenians, Georgians and other Caucasians from a common ancestor, namely, from Targamos (Togormah)—The Life of the Fore-Patriarchs and Ancestors of the Georgian Kings, which is represented in the introductory part of The Georgian Chronicles and is dated back to the end of the11th, is a compiled work that mainly contains, on the one hand, an old Georgian genealogical-geographical story about Tarshish’s son Kartlos (Iber) and his six brothers ( Egros, Movakan, Heros, Bardos, Lekan and Caucas)created at the end of the 6th c.-first half of the 8th c. based on Byzantine works, and on the other hand, a genealogical story created in old Armenian historiography about Targamos and his son Hayk that went through certain steps of development as well. In the process of synthesizing, Togormah (Targamos) and his son Hayk (Haos)were inserted between Tarsish and his son Kartlos (Iber), which violated the Biblical scheme as well as the structure of the sentence in which the insertion was made. The goal of developing the synthesized scheme was to bring evidence of the common origin of Georgians and Armenians, as long as quite a large number of Armenians,because of the incorporation of a large part of Armenian territories within Georgian borders, became citizens of Georgia. At the same time, the story also offers a justification in the eyes of the Muslim world for the claims of Georgia for Armenian territories. According to the newly-created synthesized scheme, Georgia was “the successor brother” of Armenia(Haos//Hayk) and considering the absence of Armenian states, i.e., “the elder brother”,Georgia was the only legal heir of Armenian territories. 展开更多

The geographical information reflected in a traditional genealogy mainly has two aspects.On the one hand,it is the administrative division,human geography,and other general environmental conditions of the ethnic group.On the other hand,it points to the specific origin and migration of family members in the family tree.In addition to affecting the formation and evolution of language,these factors will also affect the development trend of language behavior by promoting the psychology of people’s geographic identity.From these data,we find that geographic factors in the genealogy have a non-negligible relationship with the geographical spread of the language of the genealogy. 展开更多

Regarding the Chan Buddhism lamp records from the Song Dynasty and starting from Jing De Zhuan Deng Lu,the category of“enlightened masters in Chan Buddhism”禪門達者was listed separately,meaning a separate category was established for eccentric monks who pretended to be crazy,had unknown inheritance and miraculous deeds,and were difficult to classify.The following lamp records named this category of eccentric monks as“sages”散聖,or“saints”應化聖賢,which constructed another historical genealogy for the special Chan Buddhism eccentric monks.Moreover,the early lamp records included mostly idiosyncratic mad monks from previous dynasties.Since the Southern Song Dynasty,Chan Buddhism historical materials included many sages from the current dynasty.Therefore,this study mainly examines how the genealogy of Chan Buddhism eccentric monks was constructed in Song Dynasty Chan Buddhism lamp records,including quotations,and organizes the images of eccentric monks in the Song Dynasty,as written in Chan Buddhism historical materials,in order that the meaning of existence of these enlightened masters,sages,saints,etc.,included in the genealogy of Song Dynasty eccentric monks in the history of Chan Buddhism can be reflected. 展开更多

Anthropologists are often the custodians of long-term unidentified human remains though their positions as curators of university or museum skeletal collections.Various factors decrease the solvability of these legacy cases including the passage of time,the loss of provenience for specific cases,and lack of documentation or case records.While anthropologists can contribute important information toward identification,it is often necessary to explore novel and cross-disciplinary strategies to resolve difficult cold cases.In long cold cases,the postmortem interval,in particular,may be difficult to estimate leading to further challenges in achieving identification.Modern advances in radiocarbon bomb pulse dating,isotope analysis,and actualistic studies have contributed to positive identification of unidentified human remains in some legacy cases,but may not be available to all forensic practitioners and law enforcement from resource-poor agencies.Pooling resources,as well as collaborating with professionals outside of forensic anthropology,is a useful strategy to pursue when anthropological methods are exhausted.The case study presented here demonstrates a collaborative approach between forensic anthropologists,forensic genetic genealogists,and law enforcement in a century-old homicide.The dismembered and mummified parts of a male body were recovered in a remote cave in 1979 and again in 1991.Despite forensic anthropologists creating and updating the biological profile over the decades from recovery to present,no identification was made until the application of forensic genetic genealogy(FGG)to the case in 2019.New interpretations of bone microstructure and trauma analysis are presented for the case,alongside the historical documentation and“proof of life”evidence used by the genealogy team.A review of the FGG methods underscores the challenges in this case(e.g.significant endogamy,multiple aliases used by the victim)and the steps taken toward resolution.Ultimately,a combined anthropology and genealogy approach resulted in a confirmed identity for a man who was murdered in 1916. 展开更多

This article focuses on a genre of late imperial women's writing that has rarely been explored, namely, genealogy writing. By "genealogy writing," I refer not only to family histories composed of lists of descendants and ancestors' biographies, but also, more broadly, to writings specifying the terms for ancestral rites. This genre of writing conferred ritual and moral authority, especially during a time when ancestral worship became the defining attribute of a lineage and was held in supreme importance by local families and lineages. Women, however, almost never enjoyed such authority. My selection of the case of Yuan Jingrong (1786-ca.1852, wife to the Vice Minister of Rites, Wu Jie) is based precisely on this concern of genre. By appropriating the authority conferred by genealogy writing, Yuan Jingrong gained the upper hand in her family's dramatic shifts of fortune and power, and pushed women's self-empowering strategies to extraordinary proportions. 展开更多

[Objectives]To explore the phylogenetic diversity of wetlands at the source of the Qin River and provide data reference for future research.[Methods]Taking survey data(July,2016)of plants in wetlands at the source of Qin River as research object,this study utilizes Phylocom 4.2 to construct plant(in wetlands at the source of Qin River)genealogical tree for 72 non-angiosperm species within research area,besides,the paper adopts Pedigree diversity index(PD),community pedigree structure index(net Relatedness index,NRI and Nearest Taxon Index,NTI)to analyze pedigree diversity and pedigree structure of plants in wetlands at the source of Qin River.This paper is going to explain the scientific question:pedigree diversity,pedigreeβdiversity,and pedigree structure of plants in wetlands at the source of Qin River,in order to study on relatedness and stability of community.[Results]The effect of habitat filtration will result in similar species adaptation and close genetic relationships in the community,manifesting as genealogy aggregation.On the contrary,the effect of competitive exclusion can lead to distant species genetic relationships in the community,manifesting as genealogy divergence.In this study,there was a tendency of aggregation among the species in sample plot S5,which indicated that the effect of habitat filtration was dominant in this plot,and in S2 and S6 the species had a decentralized trend.The NRI and NTI values in other plots were different in the positive and negative.[Conclusions]This research serves as an initial exploration of the phylogenetic diversity and community assembly mechanisms in the wetlands at the source of Qin River.Further studies incorporating environmental factors and human activities could provide deeper insights into community ecology phenomena and assembly mechanisms. 展开更多

[Method] The ploidy level of 38 roses was examined by the flow cytometry. [Result] The four Chinese old roses that influenced breeding of mod- ern roses were diploid. Since the progenies of these Chinese old roses crossed with the tetraploid European old roses were almost tetraploid, it is probable that the pro- genies were arisen by the unreduced gametes of the Chinese old roses. Other Chi- nese old roses analysed were triploid, it was presumed that triploids and diploids were intermingled in China of the 1700s and the plant hunters preferred the more fertile Chinese old roses to be introduced to Europe. Sixteen hybrids of Chinese old rose originated in China consisted of six diploids, five triploids and five tetraploids. [Conclusion] Although these diploid Chinese roses might be the progeny brought by crossing among only Chinese old roses, it was considered that triploids and tetraploids have been arisen by crossing between European old roses and Chinese old rose. 展开更多

The genealogy is one kind of digital archives. There are many researches focusing on the digitization of family history and genealogical material. There are three types of genealogy tourism in Hakka ethnic group, including homeland tourism, family temple names tourism, and common ancestor tourism. According to the genealogy curious and return intention to homeland, there are four kinds of ancestral tourists. The recognition of the role of technology and the increasing use of the internet for genealogy development has offered new opportunities to sell accommodation and other tourism-related products. The genealogy tourism marketing matrix has four alternatives of marketing strategies: well-developed genealogy tourism, enhance ancestral connection, improve tourism infrastructure, and potential genealogy tourism. Responding to this, this study proposed four key factors which are identified to have facilitated the development of genealogy tourism, including information communication technology, resources, search for identity, and postmodern forms of tourism. There are several challenging issues in linking genealogy and tourism including interpretation, marketing built genealogy, planning for genealogy, and the interdependencies between genealogy tourism and the Hakka cultural industry. 展开更多

Fieldwork in Jiemuxi National Nature Reserve, Hunan, China, discovered morphologically indis- tinguishable groups of brown frogs that bred at different, exclusive times of the year. A principal components analysis of morphometric data, molecular analyses, and the exclusive breeding season suggested the occurrence of two species. The population that breeds during the winter was found to be an undescribed species and was subsequently described as Rana jiemuxiensis sp. nov. The new cryptic species can be identified from its congeners at the same locality by having a different breeding season and a divergent DNA barcode, Six major lineages of brown frogs were resolved with high nodal support. Rana japonica, R. chaochiaoensis, R. omeimontis, and R. jiemuxiensis have independent maternal lineages. Rana hanlunica and R. maoershanensis have essentially identical maternal lineages and they appear to represent the same species. The validity of the species R. longicrus, R. zhenhaiensis, and R. culaiensis and their genealogical relationships are not resolved and deserve further study. The genealogy indicates that sympatric cryptic lineages probably widely exist in the R. longicrus group. This highlights the importance of future more fine-scaled samplings and the inclusion of nuclear genes. 展开更多

The matrilineal genealogy of the genus Paramesotriton is hypothesized based on DNA sequences from mitochondrial NADH subunit two (ND2) and its flanking tRNAs (tRN^Arp and a partial tRNA^Ala). The genealogy identifies a highly divergent, unnamed lineage from Qixiling Nature Reserve, Jiangxi, China and places it as the sister taxon of P. chinensis. The newly discovered population differs from other congeners by several features of external morphology including having large clusters of dark brown conical warts on the dorsum of the head, lateral surface of the body and dorsolateral ridges. Its intermittent dorsal vertebral ridge is the same color as other parts of the dorsum and tail narrows gradually from the base to the tip. Further, the new population differs from all congeners by an uncorrected P-distance of more than 9.38% in ND2. Consequently, we describe the new species of Asian warty newt (Salamandridae) as Paramesotriton qixilingensis sp. nov. 展开更多

The South and Southeast Asian snake genus Oligodon, known for its egg-eating feeding behavior, has been a taxonomically and systematically challenging group. This work provides the first phylogenetic hypothesis for the genus. We use approximately 1900 base pairs of mitochondrial DNA sequence data to infer the relationships of these snakes, and we examine congruence between the phylogeny and hemipenial characters. A hypothesis for the position of Oligodon within the Colubridae is also proposed. We discuss the implications of the phylogeny for previous taxonomic groupings, and consider the usefulness of the trees in analysis of behavior and biogeography of this genus. 展开更多

At some future time, each person alive today will be either an ancestor of everyone or an ancestor of no one. If the global population were unstructured by geography, race, religion and other factors, the time to future common ancestry for present-day humans would be between 33 and 66 generations, or about 1000 - 2000 years. In a structured population, migration and intermarriage are the necessary conditions for global common ancestry. Simulation of random and hierarchical migration models, shows that time to future global ancestry is generally less than triple, and often less than twice, that required for an unstructured population. The models suggest that someone alive today will become a common ancestor of the entire world population by about 5000 CE, or sooner;and that all current humans who are destined to become global common ancestors will be so by about 8000 CE, or sooner. At which time, everybody then alive will have the exact same genealogical ancestors from the present day. 展开更多

New insights into the origin of the disease are sorely needed. The present article synthesizes the results from integrative reconsideration of actual data on cancer from the viewpoint of recent developments in pathology, epidemiology, immunology, genetics, and evolution. In contrast to the 80 years old hypothesis of somatic mutative origin of carcinogenesis, the revealed set of evidence showed the origin of cancerous clones is based on inherent constitutional incongruence between the regulators of cell physiology and their targets realized in inherent immunity of cancerous cells to normal regulation of cell replication and tissue growth. The incongruence arises out of both genome mutations which led to interethnic differences in the regulator-receptor structures and intercourse between ethnoses, the regulator-receptor evolution of which has been processed to deal with different ecologic conditions. The current pandemic spread of cancer is brought about growing expansion of interethnic xenogamy favored by growing industrialization, urbanization, globalization, and migration. The proposed hypothesis of genome intrusion in the origin of cancer induces new research ideas and proposals for cancer prevention and therapy. 展开更多
