Resumen
The ancestor(s) of apparently Japan-indigenous strains of Hepatitis E virus (HEV) was probably of foreign origin, but it remains unclear when and from where it made inroads. In this study, 24 genotype 3 and 24 genotype 4 HEV strains recovered in Japan each showed a significant cluster, clearly distinct from those of foreign strains, in the phylogenetic tree constructed from an 821 nt RNA polymerase gene fragment. The evolutionary rate, approximately 0·8×10−3 nucleotide substitutions per site per year, enabled tracing of the demographic history of HEV and suggested that the ancestors of Japan-indigenous HEV had made inroads around 1900, when several kinds of Yorkshire pig were imported from the UK to Japan. Interestingly, the evolutionary growth of genotype 3 in Japan has been slow since the 1920s, whereas genotype 4 has spread rapidly since the 1980s. In conclusion, these data suggest that the indigenization and spread of HEV in Japan were associated with the popularization of eating pork.

Resumen
Cucurbita pepo is an economically important crop, which consists of cultivated C. pepo ssp. pepo , and two wild taxa ( C. pepo ssp. fraterna and C. pepo ssp. ovifera ) . We aimed at understanding the domestication and the diversity of C. pepo in Mexico. We used two chloroplast regions and nine nuclear microsatellite loci to assess the levels of genetic variation and structure for C. pepo ssp. pepo 's landraces sampled in 13 locations in Mexico, five improved varieties, one C. pepo ssp. fraterna population and ornamental C. pepo ssp. ovifera . We tested four hypotheses regarding the origin of C. pepo ssp. pepo 's ancestor through approximate Bayesian computation: C. pepo ssp. ovifera as the ancestor; C. pepo ssp. fraterna as the ancestor; an unknown extinct lineage as the ancestor; and C. pepo ssp. pepo as hybrid from C. pepo ssp. ovifera and C. pepo ssp. fraterna ancestors. Cucurbita pepo ssp. pepo showed high genetic variation and low genetic differentiation. Cucurbita pepo ssp. fraterna and C. pepo ssp. pepo shared two chloroplast haplotypes. The three subspecies were well differentiated for microsatellite loci. Cucurbita pepo ssp. fraterna was probably C. pepo ssp. pepo 's wild ancestor, but subsequent hybridization between taxa complicate defining C. pepo ssp. pepo 's ancestor.

Resumen
The only play by Kezilahabi, Marx`s shorts, is a political satire, so pungent that it has not yet been published, although its photocopied manuscript has been in circulation for almost twenty years (it is dated 1978). Probably it was written soon after Julius Nyerere`s pamphlet Azzmio la Arusha baada ya Miaka Kumi (1977), where he overtly admitted for the first time the failure of his policy, clearing the way for critical literary works.

Resumen
African rice (Oryza glaberrima) and African cultivation practices are said to have influenced emerging colonial plantation economies in the Americas(1,2). However, the level of impact of African rice practices is difficult to establish because of limited written or botanical records(2,3). Recent findings of O. glaberrima in rice fields of Suriname Maroons bear evidence of the high level of knowledge about rice among African slaves and their descendants, who consecrate it in ancestor rituals(4,5). Here we establish the strong similarity, and hence likely origin, of the first extant New World landrace of O. glaberrima to landraces from the Upper Guinean forests in West Africa. We collected African rice from a Maroon market in Paramaribo, Suriname, propagated it, sequenced its genome(6) and compared it with genomes of 109 accessions representing O. glaberrima diversity across West Africa. By analysing 1,649,769 single nucleotide polymorphisms (SNPs) in clustering analyses, the Suriname sample appears sister to an Ivory Coast landrace, and shows no evidence of introgression from Asian rice. Whereas the Dutch took most slaves from Ghana, Benin and Central Africa(7), the diaries of slave ship captains record the purchase of food for provisions when sailing along the West African Coast(8), offering one possible explanation for the patterns of genetic similarity. This study demonstrates the utility of genomics in understanding the largely unwritten histories of crop cultures of diaspora communities.

Resumen
Introduction La traite transatlantique, du 15ième au 19ième siècle, a changé radicalement la démographie des Amériques. Des milliers d'esclaves africains ont réussi à échapper aux plantations des colonisateurs européens, et ont formé des colonies indépendantes de peuples libres (ou 'Marron'). Dans notre travail, nous étudions quatre communautés Noir Marron de la Guyane française et du Surinam, ainsi que d'autres populations ayant un héritage africain : Brésil et Colombie, ainsi que des populations d'Afrique de l'Ouest : Bénin, Côte-d'Ivoire et Mali. Afin de définir les différentes histoires démographiques, ces populations ont été caractérisées à l'aide de plusieurs marqueurs génétiques des lignées uniparentales: chromosome Y (17 Y-STR et 96 Y-SNP), ADN mitochondrial (génomes complet), et de données pan-génomiques (4,5 millions de SNP). Résultats Les ADN paternels et maternels ont mis en évidence différents modèles de biais sexuels dans les populations afro-brésiliennes et afro-colombiennes, ce qui suggère des comportements de mariages préférentiels. À l'opposé, les communautés Noir Marron présentent l'origine africaine la plus élevée pour tous les systèmes génétiques analysés (supérieure à 98%). Dans ces communautés, on note l'absence de flux génique avec les groupes non-africains, et également des coefficients de consanguinité très élevés. En accord avec les études linguistiques, les communautés Noir Marron montrent une origine géographique africaine associée aux royaumes historiques de l'Afrique de l'Ouest qui existaient au Bénin durant la traite des esclaves. En accord avec les études historiques, l'origine des afro-colombiens montre des liens génétiques avec la région de la Côte de l'Or, et celle des afro-brésiliens avec la région de l'Afrique centrale. Conclusions Cette étude fournit une importante information génétique sur les afro-américains et nous permet de reconstruire les liens brisés avec leur passé africain. Les communautés Noir Marron montrent une identité africaine très élevée, reliée au Golfe du Bénin. Les populations afro-brésiliennes et afro-colombiennes font apparaitre différentes histoires démographiques en raison de leur passé colonial différent. Confronté avec les études historiques, la génétique permet de mieux appréhender l'identité ethnique africaine sur les deux rives de l'Atlantique
Background The transatlantic slave trade, from the 15th to the 19th centuries, changed dramatically the demography of the Americas. Thousands of enslaved Africans managed to escape from the plantations of European colonizers, and formed independent African settlements of free people (or 'Marron'). Here, we study four Noir Marron communities from French Guiana and Surinam, as well as other populations with noteworthy African heritage in Brazil and Colombia, and West African populations in Benin, Ivory Coast, and Mali. To uncover different population histories, these populations were specifically characterized using different genetic markers based on 17 Y-STRs, 96 Y-SNPs, whole mtDNA genome, and genome-wide SNP data (4.5 million autosomal SNP). Results Paternally and maternally inherited DNA highlighted different patterns of sex-biased gene flow in both Afro-Brazilian and Afro-Colombian populations that suggest different preferential marriage behaviours. In sharp contrast, the Noir Marron communities presented the highest African ancestry in all genetic systems analysed (above 98%). These communities have apparently a null gene flow with non-African groups, and also present elevated inbreeding coefficients. In good agreement with linguistic studies, the Noir Marron communities showed a biogeographical ancestry associated with historical West African Kingdoms that existed in modern Benin during the slave trade. Afro-Colombians indicated genetic ancestry linked with the Gold Coast region. While Afro-Brazilian genetic ancestry was linked with the West Central African region, also supported by historical research. Conclusions This study provides specific genetic information in African Americans and thereby helps us to reconstruct broken links with their African past. The Noir Marron communities revealed a remarkably high African identity, which is still linked to Bight of Benin region. The Afro-Brazilian and Afro-Colombian populations present different demographic histories because of their different colonial pasts. Within an appropriate historical framework, genetic ancestry can add further understanding of ethnicity in African populations throughout the Atlantic world

Resumen
A dissertation submitted to the Faculty of Health Sciences, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Master of Science in Medicine in the Division of Human Genetics Pretoria, 2016
Oral history and anthropological data indicate that several Xhosa clans in the mPondoland region of the Eastern Cape (formerly the Transkei) were established by individuals of non-African ancestry. Several oral and few written accounts state that circa 1730, survivors from trade- and slave-bearing vessels shipwrecked along the Wild coast of the Eastern Cape. Castaways who had survived the shipwrecking events had assimilated with the indigenous people of the area, married local women, and established clans of their own. The group of clans, which claim their ancestors to be of European and/or Eurasian descent, are known as the abeLungu, meaning “the Whites”. These clans are discerned from other local groups by variations in the practice of rituals from that of traditional Xhosa rituals, as these clans retain an affiliation with the European culture to which their ancestors belonged. Nowadays they still retain subtle phenotypic features like blue eyes, which are seen in several clan members. The identity of these clans has, to date, been shrouded in myth due to conflicting versions in the oral history and anthropological data, which leave the picture of the cultural identity of the abeLungu people unresolved. With the advent of molecular biology, it has been shown that DNA may be used as a tool to trace population ancestry. The non-recombining region of the Y chromosome (NRY) serves as a marker for patrilineal ancestry and similarly mitochondrial DNA, which is inherited from mother to progeny, serves as a record for the matrilineal human history. This study aims at exploring the degree of agreement between culture and genetics by investigating the genetic variation of the abeLungu - a culturally and geographically defined group. Focus is placed on their patrilineal history, since their oral history indicates clan progenitors to be predominantly male, but also due to the patriarchal social structure with regards to marriage and kinship of the abeLungu. Buccal swabs were taken from which extracted DNA was used to perform Y chromosome microsatellite short-tandem repeat (STR) and SNP minisequencing using a total of 60 SNPs and 19 STRs taken from 146 abeLungu clan-affiliated individuals and 42 non-clan members from the greater region of mPondoland. Mitochondrial DNA SNP determination and sequencing analyses were also performed on 188 males and 10 females (the wives/ direct relatives of primary male clan elders), so as to trace the matrilineal origins and examine the congruence between the molecular and anthropological data. The frequency of European and Eurasian haplogroups in the male samples was 69.86%, which are delineated predominantly by European haplogroups R1b, and West Asian haplogroup R1a1a. Haplogroups G, I and Q which occur at high frequencies in Europe and Eurasia were observed as well. It has also been observed (which was as expected) that culturally defined groups with a unique (or a limited number of) common origins whose membership is inherited only through the male line showed a relatively low intragroup variation for genetic markers similarly transmitted. The maternal lineages of the abeLungu clan members segregate with ancient and deeply-rooted African haplogroup L lineages, with increased diversity on account of migration due to their exogamous marriage practices. This study affirms the non-African paternal origin of the abeLungu clans of lineages originating from few distinct founders, and elucidates the previously unresolved oral accounts of genealogical information, which has been transferred across generations with considerable accuracy, despite its propensity for change over time.

Resumen
AbstractRarely in archaeology do we see the flesh and blood of ancient people living their lives? In Australia, a unique archaeological site discovered in 2006 allowed us to do just that as people went about their daily lives during the last glacial maximum. The site is a palaeofilm of men, women and children, walking, running and meandering across a wet area that was obviously special to them. While hundreds of footprints displayed this unusual but moving life tapestry, details of their behaviour and other marks they left behind were difficult or impossible to interpret. Moreover, were some of the marks made by humans or just artefacts of nature? Perhaps we were not making the right interpretation and not picking up clues to the everyday life of these people as well as we might. We required interpretative skills we did not have. To help us we needed to partner with people who had such skills. Pintubi people from Central Australia were asked to help, and they were some of the last people contacted by White Australia in the early 1960s. They had the vital skills of tracking, skills that had kept them alive in the harsh Tanami and Gibson deserts of Central Australia. It was possible that they would be able to apply those skills in reaching out to their ancient Dreamtime ancestors. They also brought that Dreamtime to us.

Resumen
‘What are monuments for? Possible landmarks on the urban map: Paris and London’ is the title of a performance script that Himid wrote to accompany London and Paris Guidebooks, a mixed-media work she created in 2009 and which is the subject of this chapter. ‘When I was in Paris a few months ago, I came across a delightful little guide book about London’, her imaginary narrative begins. ‘It lists nearly 300 places of interest. These, it claims, range from the National Gallery to “gruesome” Old St Thomas’s operating theatre and from ancient Charterhouse to modern Canary wharf’. Losing no time in communicating her subversive and satirical message, she relies on biting irony to declare that ‘I was glad to see the publishers had included most of the important landmarks, signalling the contribution made by Africans of the Black diaspora to this great and crazy city’. Clearly, this ‘delightful little guide book’ has succeeded in mapping ‘nearly 300 places of interest’ only to fail to memorialise the ‘contributions made by Africans of the Black diaspora’: a failure Himid takes to task by creating her own radically revisionist and Black-centric tourist guides. As works of social, moral and political reparation, Himid deliberately borrows from jingoistic nationalist language in her newly conceptualised London and Paris Guidebooks in order to decode and destabilise the ideological, political and cultural stranglehold exerted by celebratory narratives that trade only in white supremacist ‘landmarks’. Working across pictorial and textual modes, she endorses strategies of editing, collaging, insertion and juxtaposition to re-present as well as represent the missing ‘contribution made by Africans of the Black diaspora’. With Himid rather than nationalist apologists as our guide, we experience a very different London and Paris. Here she equips her audiences with a radical and revolutionary ‘narrative’ in which these ‘guide books’ texts’ and ‘a random selection of some of the monuments’ visibilise rather than invisi- bilise ‘The living/ The dead/ The ancestors/ The descendants’.

Resumen
By the end of the decade the time revolution was a done deal. Moulin-Quignon still reverberated, but in 1865 Lubbock produced the first guided tour of the Old Stone Age, in which he accused Lyell of plagiarism. In Pre-Historic Times he filled the new space of deep history with stone tools to show an evolutionary pathway from St Acheul to the Neolithic monuments of Avebury and Stonehenge. Tracing history back was matched by the anthropologist Edward Tylor, who traced it up. Both men were interested in the evolution of racial groups and accounting for the world’s hunters and gatherers. In a typically upbeat assessment, Lubbock saw the lesson of the past as providing hope for the future. Victorian ‘savages’ at the uttermost ends of the earth had not degenerated from a civilized state. They had the potential to evolve, as his ancestors in Europe had done. Unwritten history was making universal history possible. The decade saw deaths and career changes. Prestwich largely abandoned the time revolution, married Falconer’s niece, Grace McCall, and became an Oxford professor. Falconer and Boucher de Perthes died, while Lubbock entered Parliament in 1870. Prestwich’s fixed notion of a single ice age was challenged by James Croll, who painstakingly worked out the changes in the elliptical orbit of the Earth, and from these proposed multiple ice ages. As a bookend to the decade Evans published his fact-rich volume on ancient stone implements. The path of deep history was now set in stone.

Resumen
Pigs are vital to the economy and critical in meeting the ever increasing demand for livestock and livestock products in most parts of the world. Pig is one of the oldest domesticated animals, though their ancestory is still shrouded in controversy due to lack of sufficient archaeological and genetic information. However, most of the breeds are thought to have descended from the Eurasian Wild Boar (Sus scrofa). This chapter will therefore look at the African pig under the following headings: Introduction, origin of pigs – genetic and historical/archaeological evidences, pig breeds in Africa, economic importance of pig production in Africa, marketing of pigs in Africa, herd health management of pigs in Africa, and challenges affecting pig production in Africa.

This chapter covers the beginning of organized interest in Catholic teachings and values, tracing who inspired the birth of a Catholic community in Korea. It then discusses the papal injunction against the use of spirit tablets in ancestor memorial services and how obedience to that rule from Rome necessitated disobeying the law in Korea. The result was the martyrdom of two early Catholics, which frightened many of the early yangban Catholics into leaving the church.

Resumen
Stone tools have a continuous record extending some 3.3 million years. Our hominin ancestors engaged in relatively simple stone flaking, and stone tools of extreme complexity were produced by cognitively modern humans in the Pleistocene and Holocene. For this reason, stone tools offer a tangible means for tracking the evolution of cognition in our genus. This chapter discusses a recent series of experiments controlled for modern flintknapper intent, the results suggesting that aspects of ancient tool forms sometimes viewed as deliberate can in fact be produced with no more intention than that seen in the removal of individual flakes. But the removal of individual flakes is itself a cognitively challenging task, one that places the earliest hominin flintknappers across the “cognitive Rubicon” from their primate relatives.
