How to measure group selection in real-world populations

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....

How Altruism Can Prevail Under Natural Selection

Introduction Why have we economists been convinced for so long that our old friend, homo eco-nomicus must be selfish? No doubt we find considerable support for this hypothesis in the behavior of our colleagues. We might also expect that evolutionary pressures tend to produce selfish behavior–with the notable exception of the relation between parents and offspring. But can we expect natural sele...

How to measure metacognition

The ability to recognize one's own successful cognitive processing, in e.g., perceptual or memory tasks, is often referred to as metacognition. How should we quantitatively measure such ability? Here we focus on a class of measures that assess the correspondence between trial-by-trial accuracy and one's own confidence. In general, for healthy subjects endowed with metacognitive sensitivity, whe...

How to measure efficiency

The measurement of the efficiency of some selection or process is always an important part of the analysis of experimental data. The statistical techniques needed to determine the efficiency and its uncertainty are reviewed, based on the use of the Bayes’ theorem. Uniform and non-uniform priors are considered in two real-life examples. The use of the uncertainties in practical cases is also con...

Lab 1 - Natural Selection in the Goldenrod Gall Fly System: Effects of Predators and Parasites Week 1: What is natural selection and how can we measure it?

Objectives: • Understand the concepts of natural selection, heritable variation, and selection pressures • Become familiar with the experimental system in which we will measure natural selection (read this lab and the Natural History article “Just Lookin’ for a Home” which is posted on Blackboard before you come to lab). • Develop testable hypotheses regarding natural selection in the goldenrod...
