The "environment" of an organism often remains a background concept, often not subject to explicit analysis. My working to foreground it forms the foundation for my contributions to understanding agency, success, and progress.
ON THE UBIQUITY OF
Environmental heterogeneity is invoked as a key explanatory factor in the adaptive evolution of a surprisingly wide range of phenomena. This paper aims to explain and analyze this widespread explanatory scheme. I suggest how the scheme can be contrasted with how environmental heterogeneity was analyzed in the Modern Synthesis, namely as a source of contingency. However, I argue that the concept of heterogeneity adaptation needs more precision, and propose a distinction between two broad categories: adaptations resulting from selection by a specific pattern of environmental heterogeneity, and adaptations resulting from exploiting novel patterns of environmental heterogeneity.

SELECTION IN A COMPLEX WORLD
How can we assign a magnitude and direction to natural selection, given that natural environments are incredibly complex? In this contribution to the causalist-statisticalist debate, I suggest natural selection is most like an entropic force, tending towards stable equilibrium. Published in Erkenntnis in 2018.
Even though krill reproduce at a higher rate than orca, they do not share a common selective environment. Why?

NATURAL SELECTION, PLASTICITY, AND THE RATIONALE FOR LARGEST-SCALE TRENDS
Trends in adaptations to variability are an expected feature of evolution by natural selection. Published in Studies in History and Philosophy of Science Part C in 2018
THE SELECTIVE RATIONALE FOR PROGRESS
Natural selection over macroevolutionary scales provides a rationale for a pattern of evolutionary unfolding, characterised by radiation across an increased range of exploitation of environmental heterogeneity.

HUMAN SUCCESS: EVOLUTIONARY ORIGINS AND ETHICAL IMPLICATIONS
Scientists often talk about the human species as "extraordinarily successful" from an evolutionary perspective. We have spread across the world, diversified, and flourished. Yet in many ways, this way of thinking is at odds with the non-anthropocentric post-Darwinian view of life, where each species is adapted to its own local environment. How to make sense of this?
For this edited volume I invited leading scientists and philosophers to reflect on this question (with Grant Ramsey). What does it mean for our species—or for any species—to be successful? What caused our apparent evolutionary success, and how should we cope with the consequences of ‘excessive’ success, such as climate change and biodiversity destruction? Should we perhaps seek out novel forms of success, by enhancing our physical, cognitive, and even moral capacities?

ENVIRONMENT AND SUCCESS IN HUMAN EVOLUTION
My own analysis of what it means to call the human species "extraordinarily successful". I argue there are two types of success at play: competitive success (capturing resources at the expense of other species) and colonising success (extracting novel resources)
THE SERVICE VIEW ON ENHANCEMENT
Trust and service should be taken as the central principles in the debate on the ethics of enhancement interventions. The ethically commendable enhancements are those that are used for service and in this way do not erode interpersonal trust. Based on the evolutionary anthropology of prestige and dominance.
