More on how and why: a response to commentaries
Biology & Philosophy, 2013
We are grateful to the commentators for taking the time to respond to our article. Too many interesting and important points have been raised for us to tackle them all in this response, and so in the below we have sought to draw out the major themes. These include problems with both the term 'ultimate causation' and the proximate-ultimate causation dichotomy more generally, clarification of the meaning of reciprocal causation, discussion of issues related to the nature of development and phenotypic plasticity and their roles in evolution, and consideration of the need for an extended evolutionary synthesis.

On Reciprocal Causation in the Evolutionary Process
Evolutionary Biology, 2017
discuss some promising empirical and analytical tools to study reciprocal causation and the implications for the EES. Finally, I briefly discuss how quantitative genetics can be adapated to studies of reciprocal causation, constructive inheritance and phenotypic plasticity and suggest that the flexibility of this approach might have been underestimated by critics of contemporary evolutionary biology.
2009
We have argued elsewhere that natural selection is not a cause of evolution, and that a resolution-of-forces (or vector addition) model does not provide us with a proper understanding of how natural selection combines with other evolutionary influences. These propositions have come in for criticism recently, and here we clarify and defend them. We do so within the broad framework of our own'hierarchical realization model'of how evolutionary influences combine.

Biological functions are causes, not effects: A critique of selected effects theories
Studies in History and Philosophy of Science, 2024
The theory of Selected Effects (SE) is currently the most widely accepted etiological account of function in biology. It argues that the function of any trait is the effect that past traits of that type produced that contributed to its current existence. Its proper or etiological function is whatever effect was favoured by natural selection irrespective of the trait's current effects. By defining function with respect to the effects of natural selection, the theory claims to eschew the problem of backwards causality and to ground functional normativity on differential reproduction or differential persistence. Traditionally, many have criticised the theory for its inability to envisage any function talk outside selective reproduction, for failing to account for the introduction of new functions, and for treating function as epiphenomenal. This article unveils four additional critiques of the SE theory that highlight the source of its critical problems. These critiques follow from the fact that natural selection is not a form of work, but a passive filter that merely blocks or permits prior functioning traits to be reproduced. Natural selection necessarily assumes the causal efficacy of prior organism work to produce the excess functional traits and offspring from which only the best fitted will be preserved. This leads to four new incapacities of the SE theory, which will be here analysed: (i) it provides no criterion for determining what distinguishes a proper from an incidental function; (ii) it cannot distinguish between neutral, incidental, and malfunctioning traits, thus treating organism benefit as irrelevant; (iii) it fails to account for the physical work that makes persistence and reproduction possible, and (iv) in so doing, it falls into a vicious regress. We conclude by suggesting that, inspired by Mills and Beatty's propensity interpretation, the aporia of backward causation implicit in anticipatory accounts of function can also be avoided by a dispositional approach that defines function in terms of work that synchronously counters the ubiquitous tendency for organism entropy to increase in the context of far-fromequilibrium thermodynamics.
Natural Selection and Multi-Level Causation
Philosophy & Theory in Biology, 2011
In this paper, using a multilevel approach, we defend the positive role of natural selection in the generation of organismal form. Despite the currently widespread opinion that natural selection only plays a negative role in the evolution of form, we argue, in contrast, that the Darwinian factor is a crucial (but not exclusive) factor in morphological organization. Analyzing some classic arguments, we propose incorporating the notion of ‘downward causation’ into the concept of ‘natural selection.’ In our opinion, this kind of causation is fundamental to the operation of selection as a creative evolutionary process.
