Mother nature's tolerant ways: why non-genetic inheritance has nothing to do with evolution

Recently a number of theorists have suggested that evolution can use non-genetic or environmental inheritance to pass on adaptations (e.g. Mameli, 2004). Furthermore, it has been suggested that nongenetic, or environmental factors, can play a central role in the process of evolution that is not captured by the neo-Darwinian view which places natural selection centre-stage (e.g. Odling-Smee, Laland & Feldman, 2003). In this paper we present and clarify neo-Darwinian theory and then take issue with the notions of contemporary gene-centred selection and inheritance that non-genetic inheritance theorists have used. We claim that they have misunderstood the distinction and relationship between intrinsic and extrinsic inheritance and we clarify this with a number of examples from the behavioural and biological sciences. According to this analysis there is no such thing as biologically independent nongenetic inheritance, all extrinsic inheritance is a consequence of traits and dispositions that are intrinsic to an organism and intrinsic design can only be explained through neo-Darwinism. We point to the implications this view has for current conceptions of cultural evolution

An Open-Source Simulator for Cognitive Robotics Research: The Prototype of the iCub Humanoid Robot Simulator

This paper presents the prototype of a new computer simulator for the humanoid robot iCub. The iCub is a new open-source humanoid robot developed as a result of the “RobotCub” project, a collaborative European project aiming at developing a new open-source cognitive robotics platform. The iCub simulator has been developed as part of a joint effort with the European project “ITALK” on the integration and transfer of action and language knowledge in cognitive robots. This is available open-source to all researchers interested in cognitive robotics experiments with the iCub humanoid platform

Robot life: simulation and participation in the study of evolution and social behavior.

This paper explores the case of using robots to simulate evolution, in particular the case of Hamilton's Law. The uses of robots raises several questions that this paper seeks to address. The first concerns the role of the robots in biological research: do they simulate something (life, evolution, sociality) or do they participate in something? The second question concerns the physicality of the robots: what difference does embodiment make to the role of the robot in these experiments. Thirdly, how do life, embodiment and social behavior relate in contemporary biology and why is it possible for robots to illuminate this relation? These questions are provoked by a strange similarity that has not been noted before: between the problem of simulation in philosophy of science, and Deleuze's reading of Plato on the relationship of ideas, copies and simulacra

Back to the Future of the Body

What can the past tell us about the future(s) of the body? The origins of this collection of papers lie in the work of the Birkbeck Institute for the Humanities which has been involved in presenting a series of international workshops and conferences on the theme of the cultural life of the body. The rationale for these events was that, in concepts as diverse as the cyborg, the questioning of mind/body dualism, the contemporary image of the suicide bomber and the patenting of human genes, we can identify ways in which the future of the human body is at stake. This volume represents an attempt, not so much to speculate about what might happen, but to develop strategies for bodily empowerment so as to get “back to the future of the body”. The body, it is contended, is not to be thought of as an “object” or a “sign” but as an active participant in the shaping of cultural formations. And this is emphatically not an exercise in digging corpses out of the historical archive. The question is, rather, what can past lived and thought experiences of the body tell us about what the body can be(come)? Dominic Janes edited this book and contributed this chapter

An integrated machine learning and experimental approach to uncover ageing-associated processes in Fission Yeast

This work attempts to bring together knowledge of different pathways associated with cellular ageing and create connections between them using both machine learning and experimental methods. Initially, I describe the development of a novel proxy for chronological lifespan as part of the analysis pipeline of a high-throughput chronological lifespan assay in fission yeast. I then use this technique to go on to develop novel machine learning models that can predict lifespan, a complex phenotype, from simple traits, and identify ageing-associated phenotypes in fission yeast. Complementary to this, I investigate a transcription factor of interest, Hsr1, for its involvement in cellular ageing and ageing-associated processes. I describe direct regulatory targets and how it forms a network with at least four other ageing-associated transcription factors which bridges the gaps between models of ageing, and suggest mechanisms for these interactions. In this way, this work provides novel links between cellular ageing mechanisms and ageing-associated processes from both machine learning and experimental sources

El Otro Encuentro: Gigi Oltavaro-Hormillosa’s Neo-Queer Precolonial Imagining

This essay examines the performance and video art piece Cosmic Blood, by Gigi Otalvaro-Hormillosa, a queer Colombian and Filipina American artist based in the San Francisco Bay Area. It argues that Cosmic Blood is a performative intervention into dominant modes of reading the racialized and gendered Filipina body, as well as a critique of absolutist notions of national and ethnic belonging. Cosmic Blood challenges the inherent heteronormativity and masculinism of dominant notions of nation and kinship, accomplishing this imaginative intervention by its retroping of the past through a lens of queer desire. Within Otalvaro-Hormillosa’s retelling of the moment of first contact, queer bodily desire is the locus of power relations between colonizer and colonized. In this vision of the past, the figure of the Filipina is presented as a desiring subject, resisting the overdetermined tropes of woman as nation, territory, and land that are both a legacy of colonization, and a persistent narrative within contemporary articulations of national and diasporic belonging. In doing so, Cosmic Blood presents a possibility for forms of belonging that exceed the absolutism of race, ethnicity, and nation, while also imagining a utopian vision of the future that critiques the material conditions of the present

Practopoiesis: Or how life fosters a mind

The mind is a biological phenomenon. Thus, biological principles of organization should also be the principles underlying mental operations. Practopoiesis states that the key for achieving intelligence through adaptation is an arrangement in which mechanisms laying a lower level of organization, by their operations and interaction with the environment, enable creation of mechanisms lying at a higher level of organization. When such an organizational advance of a system occurs, it is called a traverse. A case of traverse is when plasticity mechanisms (at a lower level of organization), by their operations, create a neural network anatomy (at a higher level of organization). Another case is the actual production of behavior by that network, whereby the mechanisms of neuronal activity operate to create motor actions. Practopoietic theory explains why the adaptability of a system increases with each increase in the number of traverses. With a larger number of traverses, a system can be relatively small and yet, produce a higher degree of adaptive/intelligent behavior than a system with a lower number of traverses. The present analyses indicate that the two well-known traverses-neural plasticity and neural activity-are not sufficient to explain human mental capabilities. At least one additional traverse is needed, which is named anapoiesis for its contribution in reconstructing knowledge e.g., from long-term memory into working memory. The conclusions bear implications for brain theory, the mind-body explanatory gap, and developments of artificial intelligence technologies.Comment: Revised version in response to reviewer comment
