- Comparative analysis of multiple genomes in a phylogenetic framework dramatically improves the precision and sensitivity of evolutionary inference, producing more robust results than single-genome analyses can provide. The genomes of 12 Drosophila species, ten of which are presented here for the first time (sechellia, simulans, yakuba, erecta, ananassae, persimilis, willistoni, mojavensis, virilis and grimshawi), illustrate how rates and patterns of sequence divergence across taxa can illuminate evolutionary processes on a genomic scale. These genome sequences augment the formidable genetic tools that have made Drosophila melanogaster a pre-eminent model for animal genetics, and will further catalyse fundamental research on mechanisms of development, cell biology, genetics, disease, neurobiology, behaviour, physiology and evolution. Despite remarkable similarities among these Drosophila species, we identified many putatively non-neutral changes in protein-coding genes, non-coding RNA genes, and cis-regulatory regions. These may prove to underlie differences in the ecology and behaviour of these diverse species.

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- The creation and re-creation of Afro-Latin American religious movements and traditions all over the Americas is an ever-changing process. Although popular, intellectual, and judicial actors have defined Afro-Latin American religions as magic, sorcery, or merely folklore, today they are becoming increasingly respected, visible, interrelated, and recognized as national culture. Attempting to discern symbolic meanings of cultural and religious manifestations in Afro-Latin American religious communities – be they in the form of saintly images, speech patterns or narrative – scholars, increasingly seconded by practitioners, have described the ongoing processes of creation and re-creation as acculturation, transculturation, métissage or syncretism and more recently as creolization, hybridization or dialogue. In that sense, a common denominator for a large share of studies of Afro-Latin American religions is that they deal with various aspects of representations. Representing is part of everyday life as people collectively name and define the world and therefore, representations influence the dissemination of knowledge, construction of social identities as well as social transformations. Furthermore, besides their West and Central African antecedents, Afro-Latin American religions share aspects as the colonial past, the multicultural origins, Christian mission and campaigning, as well as movements such as negritude, noirisme, Black Power and transnational youth culture that together have created conflicting expressions and representations of, and within, Afro-Latin American religious communities in Diaspora settings. Such representations, of course, induce responses within Afro-Latin American religious communities. Within these communities – sometimes influenced by scholars and at fora such as international conferences – there are contestations of representations of an African or Afro-American heritage and ongoing debates about the alleged purity of religious practices. The aim of this volume is to explore how Afro-Latin American religions and some of their shared basic features, such as communication with spiritual beings, identities and the use of magic, are represented, self-represented and understood in their various socio-cultural contexts.
