How to measure group selection in real-world populations

  title={How to measure group selection in real-world populations},
  author={Simon T. Powers and Christopher Heys and Richard A. Watson},
Multilevel selection and the evolution of cooperation are fundamental to the formation of higher-level organisation and the evolution of biocomplexity, but such notions are controversial and poorly understood in natural populations. The theoretic principles of group selection are well developed in idealised models where a population is neatly divided into multiple semi-isolated sub-populations. But since such models can be explained by individual selection given the localised frequency…

Game theoretic treatments of social niche construction : how do the conditions for cooperation evolve?

It is argued that assortative mating may be an adaptation that overcomes meiotic drive, and a model for the evolution of a cooperative division of labour is presented, which broaden and deepen the understanding of how population structure evolves and how SNC transforms social dilemmas and modifies social outcomes.

Can Simpson's paradox explain co-operation in Pseudomonas aeruginosa biofilms?

This work uses the production of siderophores in Pseudomonas aeruginosa as a model system for co-operation and detects significant within-type negative density-dependant effects that vary over microcolony development that may violate Simpson's paradox.

Morphology with Light Profile Fitting of Confirmed Cluster Galaxies at z=0.84

We perform a morphological study of 124 spectroscopically confirmed cluster galaxies in the z=0.84 galaxy cluster RX J0152.7-1357. Our classification scheme includes color information, visual



The Efficacy of Group Selection is Increased by Coexistence Dynamics within Groups

It is shown that if within-group dynamics lead to a stable coexistence of selfish and cooperative types, then the range of group sizes showing some effect of group selection is much larger.

Individualist and Multi-level Perspectives on Selection in Structured Populations

Recent years have seen a renewed debate over the importance of groupselection, especially as it relates to the evolution of altruism. Onefeature of this debate has been disagreement over which kinds

Alternative formulations of multilevel selection

It is argued that the “effect hypothesis” of macroevolution, requiring, in selection among species, both the absence of group effects on organismic fitness (multilevel selection) and the direct determination of species fitnesses by those of organisms, is untestable with paleontological data.

Social niche construction : evolutionary explanations for cooperative group formation

It is argued that not only can population structure drive the evolution of cooperation, as in classical models, but that the benefits of greater cooperation can in turn drive the Evolution of population structure - a positive feedback process that is called social niche construction.

Group Selection, Altruism, and Structured-Deme Models

Structured-deme models are a valuable tool for analyzing local interactions and the resulting neighborhood selection; it is important to note, however, that if a model incorporates isolated trait groups, then within-group comparisons are entirely inappropriate for evaluating the fate of genotypes.

Social semantics: how useful has group selection been?

The last 45 years of research provide clear evidence of the relative use of the kin and group selection approaches, whereas there is no formal theory of group selection.

Group Selection

George C. Williams has here collected the work of the chief partisans with opposed viewpoints on the theory of selection at the group level to state their arguments and rebuttals, and the reader is exposed to all sides of the dispute.

Local Interaction, Multilevel Selection, and Evolutionary Transitions

It is argued that purely neighbor-structured populations, which can feature the evolution of altruism, are not properly described in multilevel terms, and the ability to “gestalt switch” between individualist and multileVEL frameworks is linked to the investigation of “major transitions” in evolution.
