  1. Biological Individuals.Robert A. Wilson & Matthew J. Barker - 2024 - Stanford Encyclopedia of Philosophy.
    The impressive variation amongst biological individuals generates many complexities in addressing the simple-sounding question what is a biological individual? A distinction between evolutionary and physiological individuals is useful in thinking about biological individuals, as is attention to the kinds of groups, such as superorganisms and species, that have sometimes been thought of as biological individuals. More fully understanding the conceptual space that biological individuals occupy also involves considering a range of other concepts, such as life, reproduction, and agency. There has (...)

  • Is ‘Assisted Reproduction’ Reproduction?Monika Piotrowska - 2018 - Philosophical Quarterly 68 (270):138-157.
    With an increasing number of ways to ‘assist’ reproduction, some bioethicists have started to wonder what it takes to become a genetic parent. It is widely agreed that sharing genes is not enough to substantiate the parent–offspring relation, but what is? Without a better understanding of the concept of reproduction, our thinking about parent–offspring relations and the ethical issues surrounding them risk being unprincipled. Here, I address that problem by offering a principled account of reproduction—the Overlap, Development and Persistence account—which (...)

  • (1 other version)Units and levels of selection.Elisabeth Lloyd - 2008 - Stanford Encyclopedia of Philosophy.
    The theory of evolution by natural selection is, perhaps, the crowning intellectual achievement of the biological sciences. There is, however, considerable debate about which entity or entities are selected and what it is that fits them for that role. This article aims to clarify what is at issue in these debates by identifying four distinct, though often confused, concerns and then identifying how the debates on what constitute the units of selection depend to a significant degree on which of these (...)

  • There Are No Intermediate Stages: An Organizational View on Development.Leonardo Bich & Derek Skillings - 2023 - In Matteo Mossio (ed.), Organization in Biology. Springer. pp. 241-262.
    Theoretical accounts of development exhibit several internal tensions and face multiple challenges. They span from the problem of the identification of the temporal boundaries of development (beginning and end) to the characterization of the distinctive type of change involved compared to other biological processes. They include questions such as the role to ascribe to the environment or what types of biological systems can undergo development and whether they should include colonies or even ecosystems. In this chapter we discuss these conceptual (...)

  • Reproduction in Complex Life Cycles: Toward a Developmental Reaction Norms Perspective.James Griesemer - 2016 - Philosophy of Science 83 (5):803-815.
    Biological reproduction is a material process of intertwined, recursive propagule generation and development, assuming that development produces simple life cycles. Most organisms, however, have more or less complex life cycles. Here, I attempt to reconcile recent articulations of a reproducer account with traditional approaches to complex life cycles by generalizing genetic demarcation criteria for life cycle generations in terms of the “scaffolded” development of hybrid reproducers. I argue that scaffolding provides a general method for identifying developmental bottlenecks and suggests in (...)
