On the basis of findings from developmental biology, some researchers have argued that evolutionary theory needs to be significantly updated. Advocates of such a “developmental update” have, among other things, suggested that we need to re-conceptualize units of selection, that we should expand our view of inheritance to include environmental as well as genetic and epigenetic factors, that we should think of organisms and their environment as involved in reciprocal causation, and that we should reevaluate the rates of evolutionary change. (...) However, many of these same conclusions could be reached on the basis of other evidence, namely from microbiology. In this paper, I ask why microbiological evidence has not had a similarly large influence on calls to update biological theory, and argue that there is no principled reason to focus on developmental as opposed to microbiological evidence in support of these revisions to evolutionary theory. I suggest that the focus on developmental biology is more likely attributable to historical accident. I will also discuss some possible room for overlap between developmental and microbiology, despite the historical separation of these two subdisciplines. (shrink)

Explaining the causal origins of what are taken to be uniquely human capacities for understanding the mind in the first years of life is a primary goal of social cognitive development research, which concerns so called “theory of mind” or “mindreading” skills. We review and discuss particular examples of this research in the context of its underlying evolutionary conceptual framework known as the neo-Darwinian modern synthesis. It is increasingly recognized that the modern synthesis is limited in its neglect of developmental (...) issues. A recent convergence of work from diverse sources, including but not limited to evolutionary developmental biology (evo-devo) and developmental systems approaches, demonstrate the need for a developmental expansion of modern evolutionary theory. We attempt to show that not only are nativist explanations of early human social cognition vulnerable to the criticisms of this developmental shift in thinking, but that these criticisms also problematize the dominant and more mainstream theories in early social cognitive development research. We conclude by discussing the importance of developmental analysis in understanding the ontogeny of cognitive capacities in individuals as well as species. (shrink)

In contrast to rigid conceptions of nonhuman animals, several philosophers have put forth ideas that suggest a more flexible and extended vision of other animals. In articulating the condition of humans in the world, philosophers have referenced ideas that necessarily bring other beings in common with humanity. Significantly, conceptions of movement and biological transformation have played a central role in these ruminations, thereby suggesting the importance of geographical variables in human/nonhuman relations. By drawing out the connections between these perspectives, this (...) paper outlines an ethics of extension. (shrink)

Developmental systems theory (DST) is a general theoretical perspective on development, heredity and evolution. It is intended to facilitate the study of interactions between the many factors that influence development without reviving `dichotomous' debates over nature or nurture, gene or environment, biology or culture. Several recent papers have addressed the relationship between DST and the thriving new discipline of evolutionary developmental biology (EDB). The contributions to this literature by evolutionary developmental biologists contain three important misunderstandings of DST.
