W D Hamilton's work on evolutionary biology has influenced scientists working across a variety of disciplines, including evolution, population genetics, and others. This work contains Hamilton's work published between 1990 and 2000, a period in which he covered various topics, often in collaboration with other scientists. With Narrow Roads Volume 3, the editor and co-authors have ably complemented an orphaned autobiographic series, while simultaneously including relevant personal recollections. After these 'Last Words' of the closely involved, we now wait for the first independent Hamilton biography. Trends in Ecology and Evolution, Vol.21 No.12.
