EVOLUTIONARY BIOLOGY:
In Search of Biological Weirdness
Elizabeth Pennisi
BERKELEY, CALIFORNIA--The late William D. Hamilton (1936-2000) was drawn to the unusual and paradoxical. His observations led to a new understanding of social interactions and shaped a generation of evolutionary biologists. At a symposium here in October honoring this giant of evolutionary biology, who died of malaria in March at age 63, about 70 researchers discussed where Hamilton's ideas have taken them.
