The Major Evolutionary Transitions in Organismality


The Social Elements of Selection: Formalizing the Gene's-Eye View of Evolution

Biologists and philosophers have long debated what units natural selection works on. Confusion has arisen over how to deal with the dual nature of selection versus inheritance, whether we should be predicting the course of selection or trying to understand adaptation, and whether to work top-down from the individual or bottom up from the gene. The latter approach, called the "gene's-eye view of evolution", is widely used by biologists but less favorably viewed by some philosophers. My project involves formalizing the gene's-eye view mathematically, with the goal of resolving the sorts of confusion noted above. Less abstractly, the work will bear on important biological questions such as how cooperation evolves, what kinds of entities are adapted, and why organisms exist.
My approach will be synthetic. I note, at the risk of too much detail, that it will lie at the intersection of the Price equation for evolutionary change, quantitative-genetic concepts, the statistical technique of path analysis, and an approach to causation from computer scientist Judea Pearl. It will start with a given gene and ask what elements need to be added – such as other genes, other individuals, or environmental factors – to explain its fate under selection. It will identify both direct and indirect causal paths and, for each, specify both the gene-phenotype relation and the phenotype-fitness relation.
From there, I plan to build up to the questions of our working group on the evolution of organismal entities, that is, those entities that show very high levels of internal cooperation with very little internal conflict. First, I will use the framework to compare and contrast the three major kinds of selection that can select for cooperative behaviors: "kin" or indirect effects moderated by correlation, "kith" effects that involve acting through other individuals, and "kind" effects that are due to true interaction. Second, I will also try to use the framework to describe evolutionary conflict and the ways that such conflict can be reduced.
