Now that we've found love what are we gonna do with it?: a narrative understanding of black identity

This paper offers an interpretation of the changes in Black identity during the last century. By drawing on psychological literature and cultural artefacts, changing understandings of Blackness are read as different narrative forms. The shift from ‘Negro’ to ‘Black’ is presented as a shift from tragicto romanticnarrative, while the ‘African’ narrative that now occupies the centre stage of Black identity represents a satiricalstory. It is suggested that with a growing awareness of being both Black and ‘something else’, the apparent opposing themes in performing Blackness can be resolved by enacting a comedynarrative. There is some evidence that the comedy narrative is present but it has yet to gain ascendancy

Evolution of genes and genomes on the Drosophila phylogeny

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
