E. O. Wilson (1974: 54) describes the problem that social organisms pose: “On what bases do we distinguish the extremely modified members of an invertebrate colony from the organs of a metazoan animal?” This framing of the issue has inspired many to look more closely at how groups of organisms form and behave as emergent individuals. The possible existence of “superorganisms” test our best intuitions about what can count and act as genuine biological individuals and how we should study them. (...) As we will discuss, colonies of certain organisms display many of the properties that we usually reserve only to individual organisms. Although there is good reason to believe that many social insects form genuine emergent biological individuals, the conclusion offered here is of a slightly different sort. I will argue that to understand some social insects' interactions and the emergent traits they give rise to, it may be helpful to shift our understanding from a community-level approach to an ecosystem-level approach. I will argue that viewing certain insect colonies (termites) as parts of ecosystems allows us to better understand some of the adaptations that have emerged from their evolution. (shrink)

Biology lacks a central organism concept that unambiguously marks the distinction between organism and non-organism because the most important questions about organisms do not depend on this concept. I argue that the two main ways to discover useful biological generalizations about multicellular organization--the study of homology within multicellular lineages and of convergent evolution across lineages in which multicellularity has been independently established--do not require what would have to be a stipulative sharpening of an organism concept.

abstract This article attempts to illustrate the continuing need to pay attention to ontological issues connected with the conduct of empirical research and subsequent policy making. Failure to do so leads to the conflation of social constructions with ideas about the thesis of an independent reality. Such category mistakes often lead to dilemmas in which culturally sensitive constructs may, on the one hand, be worthy of study because they do tell us how socially constructed categories do predict social phenomena; but, (...) on the other hand, such constructs may illustrate an unwillingness on the part of the research community to recognize the objective nature of such constructs. Some recommendations are suggested for addressing the social policy consequences of these dilemmas. (shrink)
