Place, priestly status and purity: the impact of genetic research on an Indian Jewish community

The Bene Israel is a Jewish community in western India whose origins are unknown from conventional sources. This paper discusses a genetic ancestry study that mapped Bene Israel genealogies and the impact of the study on the Bene Israel.     

The Genetics of Bene Israel from India Reveals Both Substantial Jewish and Indian Ancestry

The Bene Israel Jewish community from West India is a unique population whose history before the 18^th century remains largely unknown. Bene Israel members consider themselves as descendants of Jews, yet the identity of Jewish ancestors and their arrival time to India are unknown, with speculations on arrival time varying between the 8th century BCE and the 6th century CE. Here, we characterize the genetic history of Bene Israel by collecting and genotyping 18 Bene Israel individuals. Combining with 486 individuals from 41 other Jewish, Indian and Pakistani populations, and additional individuals from worldwide populations, we conducted comprehensive genome-wide analyses based on F_ST, principal component analysis, ADMIXTURE, identity-by-descent sharing, admixture linkage disequilibrium decay, haplotype sharing and allele sharing autocorrelation decay, as well as contrasted patterns between the X chromosome and the autosomes. The genetics of Bene Israel individuals resemble local Indian populations, while at the same time constituting a clearly separated and unique population in India. They are unique among Indian and Pakistani populations we analyzed in sharing considerable genetic ancestry with other Jewish populations. Putting together the results from all analyses point to Bene Israel being an admixed population with both Jewish and Indian ancestry, with the genetic contribution of each of these ancestral populations being substantial. The admixture took place in the last millennium, about 19–33 generations ago. It involved Middle-Eastern Jews and was sex-biased, with more male Jewish and local female contribution. It was followed by a population bottleneck and high endogamy, which can lead to increased prevalence of recessive diseases in this population. This study provides an example of how genetic analysis advances our knowledge of human history in cases where other disciplines lack the relevant data to do so.     

Black Jews in the Northern Province: a study of ethnic identity in South Africa

The article examines ways in which the Lemba people of the Northern Province of South Africa have used their oral history and traditional customs associated with distant Semitic origins in Yemen, to claim a modern Jewish identity in racially divided South Africa. While Lemba live in Mozambique and Zimbabwe as well as in South Africa, it is only in the latter that belief in a Jewish origin is found. The article seeks to show that early white missionaries and colonial officials propagated a Semitic identity for the Lemba and in their writings emphasized the differences between the Lemba and their African neighbours through comparisons of Lemba customs with Jewish communities in Europe. Such writings contributed to an ethos of a distinct identity, through which, via the establishment of the Lemba Cultural Association, middle-class Lemba intellectuals sought to promote the Lemba. This was achieved in a situation where the apartheid regime in South Africa pursued a divide and rule policy which allowed the Bantustans to discriminate against ethnic minorities under their control.     

Y chromosomes traveling south: the cohen modal haplotype and the origins of the Lemba--the "Black Jews of Southern Africa"

The Lemba are a traditionally endogamous group speaking a variety of Bantu languages who live in a number of locations in southern Africa. They claim descent from Jews who came to Africa from "Sena." "Sena" is variously identified by them as Sanaa in Yemen, Judea, Egypt, or Ethiopia. A previous study using Y-chromosome markers suggested both a Bantu and a Semitic contribution to the Lemba gene pool, a suggestion that is not inconsistent with Lemba oral tradition. To provide a more detailed picture of the Lemba paternal genetic heritage, we analyzed 399 Y chromosomes for six microsatellites and six biallelic markers in six populations (Lemba, Bantu, Yemeni-Hadramaut, Yemeni-Sena, Sephardic Jews, and Ashkenazic Jews). The high resolution afforded by the markers shows that Lemba Y chromosomes are clearly divided into Semitic and Bantu clades. Interestingly, one of the Lemba clans carries, at a very high frequency, a particular Y-chromosome type termed the "Cohen modal haplotype," which is known to be characteristic of the paternally inherited Jewish priesthood and is thought, more generally, to be a potential signature haplotype of Judaic origin. The Bantu Y-chromosome samples are predominantly (>80%) YAP+ and include a modal haplotype at high frequency. Assuming a rapid expansion of the eastern Bantu, we used variation in microsatellite alleles in YAP+ sY81-G Bantu Y chromosomes to calculate a rough date, 3,000-5,000 years before the present, for the start of their expansion.     

The origins of the Lemba "Black Jews" of southern Africa: evidence from p12F2 and other Y-chromosome markers.

The Lemba are a southern African Bantu-speaking population claiming Jewish ancestry. Allele frequencies at four different Y-specific polymorphic loci, as well as extended-haplotype frequencies that included data from several loci, were analyzed in an attempt to establish the genetic affinities and origins of the Lemba. The results suggest that > or = 50% of the Lemba Y chromosomes are Semitic in origin, approximately 40% are Negroid, and the ancestry of the remainder cannot be resolved. These Y-specific genetic findings are consistent with Lemba oral tradition, and analysis of the history of Jewish people and their association with Africa indicates that the historical facts are not incompatible with theories concerning the origin of the Lemba.

The sero-anthropology of the Rhodesian Lemba

122 Rhodesian Lemba were blood grouped to establish whether there was any serological evidence to support their claim to be immigrants into central and southern Africa; and whether their endogamous practices had resulted in blood group frequencies different from those of their present neighbours. Our results are typical of those found in central Africa, and show no similarity to the blood group frequencies of populations outside sub-Saharan Africa.     

Increased resolution of Y chromosome haplogroup T defines relationships among populations of the Near East, Europe, and Africa

Increasing phylogenetic resolution of the Y chromosome haplogroup tree has led to finer temporal and spatial resolution for studies of human migration. Haplogroup T, initially known as K2 and defined by mutation M70, is found at variable frequencies across West Asia, Africa, and Europe. While several SNPs were recently discovered that extended the length of the branch leading to haplogroup T, only two SNPs are known to mark internal branches of haplogroup T. This low level of phylogenetic resolution has hindered studies of the origin and dispersal of this interesting haplogroup, which is found in Near Eastern non-Jewish populations, Jewish populations from several communities, and in the patrilineage of President Thomas Jefferson. Here we map 10 new SNPs that, together with the previously known SNPs, mark 11 lineages and two large subclades (T1a and T1b) of haplogroup T. We also report a new SNP that links haplogroups T and L within the major framework of Y chromosome evolution. Estimates of the timing of the branching events within haplogroup T, along with a comprehensive geographic survey of the major T subclades, suggest that this haplogroup began to diversify in the Near East -25 kya. Our survey also points to a complex history of dispersal of this rare and informative haplogroup within the Near East and from the Near East to Europe and sub-Saharan Africa. The presence of T1a2 chromosomes in Near Eastern Jewish and non-Jewish populations may reflect early exiles between the ancient lands of Israel and Babylon. The presence of different subclades of T chromosomes in Europe may be explained by both the spread of Neolithic farmers and the later dispersal of Jews from the Near East. Finally, the moderately high frequency (-18%) of T1b* chromosomes in the Lemba of southern Africa supports the hypothesis of a Near Eastern, but not necessarily a Jewish, origin for their paternal line.     

Constructing black Jews: genetic tests and the Lemba--the 'black Jews' of South Africa

This commentary examines the use of Y-chromosome testing to reconstruct a genetic ancestry for the Lemba, a group in southern Africa that has long considered itself Jewish. The commentary looks especially at the reasons why this project drew such attention from the mainstream media.     

Consistent long-range linkage disequilibrium generated by admixture in a Bantu-Semitic hybrid population

Both the optimal marker density for genome scans in case-control association studies and the appropriate study design for the testing of candidate genes depend on the genomic pattern of linkage disequilibrium (LD). In this study, we provide the first conclusive demonstration that the diverse demographic histories of human populations have produced dramatic differences in genomewide patterns of LD. Using a panel of 66 markers spanning the X chromosome, we show that, in the Lemba, a Bantu-Semitic hybrid population, markers 2 cM. Moreover, analysis of Bantu and Ashkenazi populations as putative parental populations of the Lemba shows a significant relationship between allele-frequency differentials and the LD observed in the Lemba, which demonstrates that much of the excess LD is due to admixture. Our results suggest that demographic history has such a profound effect on LD that it will not be possible to predict patterns a priori but that it will be necessary to empirically evaluate the patterns in all populations of interest.     

Mine and gall predation as top down regulation in the plant–insect systems from the Cretaceous of Negev, Israel

Fossil evidence of predation on leaf mines and galls opens the way to analyzing regulatory circuits in plant–insect interaction systems and assessing their evolutionary advancement. In the Cretaceous (mid-Turonian) flora of Negev, Israel, predation traces vary from the entire gall or mine excisions to minute punctures and slits over the mine tracks. Bite marks on the borders of predation holes representing different mouthpart morphologies may show how diverse the predators were. The efficiency of predation as a top down regulation force is attested on the basis of the gall and mine abundance, gall morphologies, mine configurations, co-occurrence of different mine types on leaves, and temporary mining. In turn, the regulation efficiency is considered as a criterion of evolutionary advancement of the plant–insect community as a whole. It is suggested that the coeval Cretaceous coastal and inland communities differed in the relative significance of top-down regulation.     

Case study: the Lemba

The attempts of scholars and scientists to unravel the mystery of the ancestral origins of the Lemba are summarised, focusing on Tudor Parfitt's book, Journey to the Vanished City, and a study by an international group of genetic and social scientists. The impact of this research on identity questions is raised.     

Putting a notch in our understanding of nuclear migration

The nuclei of progenitor cells in developing neural epithelia change their position during the cell cycle through a process called interkinetic nuclear migration. Del Bene et al. (2008) report that defects in the machinery controlling this process lead to altered exposure to Notch signals and systemic effects on neurogenesis in the retina.     

Is there a connection between weather at departure sites,onset of migration and timing of soaring‐bird autumn migration in Israel?

Aims Different aspects of soaring‐bird migration are influenced by weather. However, the relationship between weather and the onset of soaring‐bird migration, particularly in autumn, is not clear. Although long‐term migration counts are often unavailable near the breeding areas of many soaring birds in the western Palaearctic, soaring‐bird migration has been systematically monitored in Israel, a region where populations from large geographical areas converge. This study tests several fundamental hypotheses regarding the onset of migration and explores the connection between weather, migration onset and arrival at a distant site. Location Globally gridded meteorological data from the breeding areas in north‐eastern Europe were used as predictive variables in relation to the arrival of soaring migrants in Israel. Methods Inverse modelling was used to study the temporal and spatial influence of weather on initiation of migration based on autumn soaring‐bird migration counts in Israel. Numerous combinations of migration duration and temporal influence of meteorological variables (temperature, sea‐level pressure and precipitable water) were tested with different models for meteorological sensitivity. Results The day of arrival in Israel of white storks, honey buzzards, Levant sparrowhawks and lesser spotted eagles was significantly and strongly related to meteorological conditions in the breeding area days or even weeks before arrival in Israel. The cumulative number of days or cumulative value above or below a meteorological threshold performed significantly better than other models tested. Models provided reliable estimates of migration duration for each species. Main conclusions The meteorological triggers of migration at the breeding grounds differed between species and were related to deteriorating living conditions and deteriorating migratory flight conditions. Soaring birds are sensitive to meteorological triggers at the same period every year and their temporal response to weather appears to be constrained by their annual routine.     

Tradition, uses and Biodiversity of rocket (Eruca Sativa, Brassicaceae) in Israel

Eruca sativa (rocket) is a native plant of Israel, documented in the old literature. A survey was conducted of the old literature of ancient Israel, including Jewish, Classical and Islamic sources up to the Middle ages. It was found that rocket was used as a garden crop and spice. It was also known as a medicinal plant and was used as an aphrodisiac, for eye infections, and for digestive and kidney problems. It is important to note that special attention was given in the old times to biodiversity within the rocket species. In the light of its high erucic acid content, native accessions were collected and evaluated as a potential future source of industrial oil. Ten accessions ofEruca sativa were cultivated in Bet-Dagan experimental farm during the 1995/96 growing season. Physiological as well as chemical parameters were recorded. Erucic acid (C 22:1) and eicosenoic acid (C 20:1) contents varied from 33 to 45% and from 7.3% to 9.8%, respectively. Special attention was given to the expressed biodiversity among the accessions and its relation to their origins.     

Representation,minorities and electoral reform: the case of the Palestinian minority in Israel

ABSTRACT

The article examines the impact of the recent change in the electoral threshold in Israel, from 2 per cent to 3.25 per cent, on the political representation of the Palestinian minority in Israel in the 2015 national election. I argue that the change in the threshold had a direct impact on Palestinian electoral representation and that this change provided incentives to Palestinian leadership to broaden their appeal and become more inclusive in their agenda. Following recent scholarship on ethnic minorities and employing the concept of “representational claims”, I suggest that through the provision of electoral incentives, institutional design can influence not only the degree of representation, but its substantive claims as well.     

Participatory destigmatization strategies among Palestinian citizens,Ethiopian Jews and Mizrahi Jews in Israel

Abstract

This study examines how members of minority groups in Israel cope with stigmatization in everyday life. It focuses on working-class members of three minority groups: Palestinian Arabs or Palestinian citizens of Israel, Mizrahim (Jews of Middle Eastern and North African origin) and Ethiopian Jews. It reveals the use of racial, ethnic and national markers in daily processes of social inclusion and exclusion in one sociopolitical context. Palestinians, a group with a fixed external identity and a limited sphere of participation, were found to use the language of race and racism when describing stigmatizing encounters. Ethiopian Jews, the most phenotypically marked group, strictly avoided this language. For their part, Mizrahi Jews perceived the very discussion of stigmatization as stigmatizing, while often using ‘contingent detachment’ to distance themselves from negative group identities. Despite differences between the communities and the powerful role of the state in establishing symbolic and social boundaries, members of all three groups expressed their intention to achieve or retain avenues for participation in the larger society.     

Biometrical analysis on populations ofOrchis israelitica,O. caspia,and their hybrids (Orchidaceae)

The population variability ofOrchis israelitica, O. caspia, and their intermediates, from two localities in Israel, was analyzed and illustrated by scatter diagram and hybrid index. It is suggested that the hybrids are a result of introgression and are closer toO. caspia. Aspects of isolating barriers between these two species are discussed.
