other to achieve their goal. There are also heroes and heroines and Ashburner identifies these as including Gerry Rubin and Suzi Lewis in particular. Heroes come in all shapes and sizes and, despite what Scott Hawley says in his Epilogue, they most definitely include Michael Ashburner. The heroes of mythology were no less fallible than the rest of us and, characteristically and endearingly, Ashburner reveals much about himself along the way (his lovehate relationship with airlines and airports, his indulgence in restaurants, his love of bird watching) and the story finishes with his being diagnosed with diabetes, the debilitating effects of which he must have had to endure during the dash to the finish. Of course, the sequence as published in March 2000 was not ‘complete’ in any sense, and will continue to be refined for some time to come. Ashburner’s story does not take long to tell, occupying a mere 53 pages. These are complemented by 14 delightful charcoal character sketches by Lewis Miller of the main protagonists, and six photographs, surprisingly few in the digital age; perhaps there wasn’t time for more. One shows six Cambridge (England not Mass) Drosophilists, including a slightly manic Michael Ashburner leaning, Morgan-like, on a bench covered with bottles of Drosophila. This seems slightly out of place as only one of the other five is mentioned in the text, and then only in passing. It was originally published in The Observer (a UK Sunday newspaper) in 1988 to accompany an article extolling the virtues of Drosophila research in general, and Drosophila research in Cambridge in particular. Its year of publication is not unrelated to the story, however, as 1988 was the year that the forerunner of the genome sequencing project, the Drosophila genome mapping programme, began. The length, or lack of it, of Ashburner’s text was not a problem for me, a blessing in fact as I am a slow reader, but it clearly was for the publishers as the last third of the book comprises extended essays by Scott Hawley and Ethan Bier. Scott Hawley’s Epilogue gives a brief history of Drosophila research from Darwin, perhaps a little further back than necessary (my paraphrase of Dobzhansky would be “Nothing makes sense in biology except in the light of genetics”), to the present day. Ethan Bier provides an Afterword which highlights the sophistication of the techniques used by Drosophilists today, and shows how much they depend on the genome sequence. Excellent though these essays are (I found in the Afterword some valuable references I had missed) I am not sure that they add much to Ashburner’s rollicking tale and may be fairly heavy going for those not in the field. It did make me wonder at whom the book is targeted. The Epilogue and Postscript will be of interest to advanced undergraduates, research students, and others working with Drosophila. The main story should have much wider appeal, but at £11/$19.95 for a hardbound volume who can complain? ‘Won for All’ will naturally be compared to Jim Watson’s ‘The Double Helix’ as both set out to give a realistic account of how an important piece of science was done. ‘The Double Helix’ is more substantial and describes a more significant achievement, but ‘Won for All’ is no less valuable for that. Science and society may have changed dramatically during the last 50 years, but scientists have not. The excitement and drama of the chase are as strong now as then and this comes through in ‘Won for All’. Hopefully it will inspire students to pursue a career in research just as ‘The Double Helix’ inspired me when I read it in a day in 1968. In 1987 the BBC turned Watson’s book into a truly gripping film ‘Life Story’, and I can imagine the same being done with ‘Won for All’. Jeff Goldblum gave a memorable performance as Jim Watson. Who will play Michael Ashburner?

The Evolution of Bird Plumage Colouration: a Role for Feather-degrading Barcteria?
The evolution of integumentary colouration in animals, and particularly its relationships with parasite-mediated sexual selection, is a controversial issue that has attracted the interest of numerous researchers (e.g. Hill, 1991; Houde & Torio, 1992; Andersson, 1994; Lozano, 1994; Badyev & Hill, 2000). Most studies concern birds, which exhibit an enormous array of colours and patterns unparalle...
متن کاملEarly Evolution of Bird-Type Language without Grammar: Duplication and Mutation
Using a series of computer simulations we have demonstrated a scenario of the early evolution of the bird-type primitive language. We do not assume wise agents who can use a grammar and manage an evolution without a grammar. Duplication and mutation of phrases is our strategy. Such a strategy is seen in wide classes of living phenomena.
متن کاملEvolution: A Genomic Guide to Bird Population History
How species responded to the climatic oscillations during the past few million years is debated. A new study analyzing the genomes of 38 bird species finds variable patterns of population growth and declines that broadly correlate with global environmental change.
متن کاملRethinking our assumptions about the evolution of bird song and other sexually dimorphic signals
Bird song is often cited as a classic example of a sexually-selected ornament, in part because historically it has been considered a primarily male trait. Recent evidence that females also sing in many songbird species and that sexual dimorphism in song is often the result of losses in females rather than gains in males therefore appears to challenge our understanding of the evolution of bird s...
متن کاملRapidly evolving traits and the comparative method: how important is testing for phylogenetic signal?
The indiscriminate application of phylogenetically based comparative methods in cross-species correlated evolution analyses has been questioned. It has been argued that traits are not always significantly correlated to their phylogenetic history, and that correcting for phylogeny in these cases may be unnecessary and may even introduce statistical error. Statistical diagnostics to test for phyl...
متن کاملHeritability of parental effort in a passerine bird.
The study of the evolution of parental care is central to our understanding of social systems, sexual selection, and interindividual conflict, yet we know virtually nothing about the genetic architecture of parental care traits in natural populations. In this paper, we use data from a long term field study of a passerine bird, the long-tailed tit (Aegithalos caudatus), to examine the heritabili...
