The empirical inadequacy of species cohesion by Gene flow

Philosophy of Science 74 (5):654-665 (2007)

Abstract

This paper brings needed clarity to the influential view that species are cohesive entities held together by gene flow, and then develops an empirical argument against that view: Neglected data suggest gene flow is neither necessary nor sufficient for species cohesion. Implications are discussed. ‡I'm grateful to Rob Wilson, Alex Rueger and Lindley Darden for important comments on earlier drafts, and to Joseph Nagel, Heather Proctor, Ken Bond, members of the DC History and Philosophy of Biology reading group, and audience members at the November 2006 meeting of the PSA, for helpful comments or discussion. Social Sciences and Humanities Research Council of Canada fellowship 752-2005-1208 supported research. †To contact the author, please write to: Philosophy Department, University of Wisconsin–Madison, 5185 Helen C.
