The history of life is the history of the association of lower level units into
higher levels of organization [Buss 1987; Maynard Smith and Szathmáry 1995;
Michod 1997; Frank 1997]. Genes became associated in chromosomes, prokaryotic
cells in eukaryotic cells, single-celled organisms in multicellular organisms, and
multicellular organisms into social groups. In understanding these evolutionary
transitions two questions need to be addressed: What caused the lower level
units to become associated into a higher level entity? And then, once the
associations were under way, whether and, if so, under what circumstances was
