Don't stand so close to me: A new view on how species coexist
...Holloway, University of London, added: "The bottom line of this work is that patterns of diversity are shaped both by ecology and by evolution." One way of capturing the essence of the new work, he added, is expressed in the concept of the 'Darwinian demon' - a hypothetical species that develops rapidly, ...University of Oregon professor wins 2004 Spiers Medal
