The Evolutionary history and domestication of Camels are largely unexplored because of the lack of well dated early archaeological records. However, limited records suggest that domestication of Camels likely happened in the late second millennium BCE. Over the time, camels have helped human for their basic needs like meat, milk, wool, dung to long routes transportation. This multifaceted animal has helped the mankind to connect through continents and in trade majorly through the Silk route. In India, both dromedary and Bactrian camels are found and their habitat is entirely different from each other, dromedaries inhabit in hot deserts and Bactrians are found mostly in cold places (Nubra Valley, Ladakh). Fewer studies on Indian dromedaries have been conducted but no such studies are done on Bactrian camels. It is needed to study the genetics of Bactrian camels to find out their genetic affinity and evolutionary history with other Bactrians found in different parts of the world. Furthermore, parallel studies on humans and Bactrian camel are required to understand the co-evolution and migration pattern of humans during their dispersal in different time periods.

Human Chagas disease originated in Latin America, being spread around the world in relation with multiple bioecological, sociocultural, and political factors. The process of the disease production and dispersion is discussed, emphasizing the human migration and correlated aspects, in the context of globalization. Positive and negative consequences concern the future of this trypanosomiasis, mainly in terms of the ecologic and sociopolitical characteristics of the endemic and nonendemic countries.

Abstract Background and objectives Mycobacterium bovis and Mycobacterium caprae are two of the most important agents of tuberculosis in livestock and the most important causes of zoonotic tuberculosis in humans. However, little is known about the global population structure, phylogeography and evolutionary history of these pathogens. Methodology We compiled a global collection of 3364 whole-genome sequences from M.bovis and M.caprae originating from 35 countries and inferred their phylogenetic relationships, geographic origins and age. Results Our results resolved the phylogenetic relationship among the four previously defined clonal complexes of M.bovis, and another eight newly described here. Our phylogeographic analysis showed that M.bovis likely originated in East Africa. While some groups remained restricted to East and West Africa, others have subsequently dispersed to different parts of the world. Conclusions and implications Our results allow a better understanding of the global population structure of M.bovis and its evolutionary history. This knowledge can be used to define better molecular markers for epidemiological investigations of M.bovis in settings where whole-genome sequencing cannot easily be implemented. Lay summary During the last few years, analyses of large globally representative collections of whole-genome sequences (WGS) from the human-adapted Mycobacterium tuberculosis complex (MTBC) lineages have enhanced our understanding of the global population structure, phylogeography and evolutionary history of these pathogens. In contrast, little corresponding data exists for M. bovis, the most important agent of tuberculosis in livestock. Using whole-genome sequences of globally distributed M. bovis isolates, we inferred the genetic relationships among different M. bovis genotypes distributed around the world. The most likely origin of M. bovis is East Africa according to our inferences. While some M. bovis groups remained restricted to East and West Africa, others have subsequently dispersed to different parts of the world driven by cattle movements.

Population policies aim to modify the growth rate, composition, or distribution of a population. In practice, they can be explicit or implicit. The two main areas in which governments attempt to control or influence through population polices are fertility and migration. ‘Population policies and future challenges’ also considers some key population challenges of the 21st century. Will fertility rates fall to replacement in sub-Saharan Africa? What is the relationship between environment, population, and consumption in different parts of the world? How will we feed and provide water for the projected 9 or 10 billion of us by 2050? What will be the impact of the ageing of the world’s population and of technological change?

Contemporary Context

Lesvos (Greece) has become over the last few years the emblem of human migration to Europe. As a consequence of the so-called “migration crisis” in 2015, people from all over the world who, first in a self-organized way and then structuring themselves into associations and organizations, wanted to bring support to migrants in transit or blocked on the island arrived developing what I define migrants’ support volunteer tourism. After defining the historical and contemporary context, I define the tourist framework and in particular this (relatively) new form of volunteer tourism. Keeping in mind that tourism – often described as a panacea for the Mediterranean islands – does not necessarily mean encounter with the other, I try to analyse voluntary tourism from the point of view of the possible relationships that are created thanks to the intersection of two forms of contemporary mobility: tourism and migration.

ABSTRACT A reference standard is widely sought for use in the quantitative bioassay of pituitary gonadotrophin recovered from urine. The biologic similarity of pooled urinary extracts obtained from large numbers of subjects, utilizing groups of different age and sex, preparing and assaying the materials by varying techniques in different parts of the world, has lead to a general acceptance of such preparations as international gonadotrophin reference standards. In the present study, however, the extract of pooled urine from a small number of young women is shown to produce a significantly different bioassay response from that of the reference materials. Gonadotrophins of individual subjects likewise varied from the multiple subject standards in many instances. The cause of these differences is thought to be due to the modifying influence of non-hormonal substances extracted from urine with the gonadotrophin and not necessarily to variations in the gonadotrophins themselves. Such modifying factors might have similar effects in a comparative assay of pooled extracts contributed by many subjects, but produce significant variations when material from individual subjects is compared. It is concluded that the expression of potency of a gonadotrophic extract in terms of pooled reference material to which it is not essentially similar may diminish rather than enhance the validity of the assay.

This book charts the transformation of one of the world's great religions during an age marked by world wars, genocide, nationalism, decolonization, and powerful ideological currents, many of them hostile to Christianity. The book traces how Christianity evolved from a religion defined by the culture and politics of Europe to the expanding polycentric and multicultural faith it is today—one whose growing popular support is strongest in sub-Saharan Africa, Latin America, China, and other parts of Asia. The book sheds critical light on themes of central importance for understanding the global contours of modern Christianity, illustrating each one with contrasting case studies, usually taken from different parts of the world. Unlike other books on world Christianity, this one is not a regional survey or chronological narrative, nor does it focus on theology or ecclesiastical institutions. The book provides a history of Christianity as a popular faith experienced and lived by its adherents, telling a compelling and multifaceted story of Christendom's fortunes in Europe, North America, and across the rest of the globe. It demonstrates how Christianity has had less to fear from the onslaughts of secularism than from the readiness of Christians themselves to accommodate their faith to ideologies that privilege racial identity or radical individualism.

Building on impressive new research into the concept of a ‘global middle ages’, this chapter offers insights into how economic formations developed around the world. Drawing on new research on both Chinese and Mediterranean economies in the ‘medieval’ period, it compares structures of economy and exchange in very different parts of the world. The point of such comparisons is not simply to find instances of global economic flows but to understand the logic of medieval economic activity and its intersections with power and culture; and, in so doing, to remind historians that economic structures, transnational connections, and the imbrications of economy and politics do not arrive only with modernity, nor is the shape of the ‘modern’ global economy the only pattern known to humankind.

The Way

In an era of mass mobility, those who are permitted to migrate and those who are criminalized, controlled, and prohibited from migrating are heavily patterned by race. By placing race at the centre of its analysis, this volume brings together fourteen essays that examine, question, and explain the growing intersection between criminal justice and migration control. Through the lens of race, we see how criminal justice and migration enmesh in order to exclude, stop, and excise racialized citizens and non-citizens from societies across the world within, beyond, and along borders. Neatly organized in four parts, the book begins with chapters that present a conceptual analysis of race, borders, and social control, moving to the institutions that make up and shape the criminal justice and migration complex. The remaining chapters are convened around the key sites where criminal justice and migration control intersect: policing, courts, and punishment. Together the volume presents a critical and timely analysis of how race shapes and complicates mobility and how racism is enabled and reanimated when criminal justice and migration control coalesce. Race and the meaning of race in relation to citizenship and belonging are excavated throughout the chapters presented in the book, thereby transforming the way we think about migration.

In the 2010s, the world is seemingly awash with waves of populism and anti-immigration movements. Yet virtually all discussions, owing to the prevailing Eurocentric perspective, bypass East Asia (more accurately, Northeast Asia) and the absence of strong populist or anti-immigration discourses or politics. This chapter presents a comparative and historical account of East Asian exceptionalism in the matter of migration crisis, especially given the West’s embrace of an insider-outsider dichotomy superseding the class- and nation-based divisions of the post–World War II era. The chapter also discusses some nascent articulations of Western-style populist discourses in Northeast Asia, and concludes with the potential for migration crisis in the region.
