Asymmetry, Developmental Stability, and Evolution

Abstract: Why does nature love symmetry? In this work, Moller and Swaddle analyze the evolutionary implication of symmetry. They advance and explain their theory that asymmetry is related to genetic stability and fitness, and that symmetric individuals appear to have quantifiable and significant advantages over their asymmetric counterparts. When assessing potential mates or competitors, animals may be able to use symmetry as an honest indication of quality. This interdisciplinary book, with its associated Web-site, should be of interest to students and researchers in the fields of ecology, evolutionary biology, genetics, and animal behaviour.

Why have birds got multiple sexual ornaments

Abstract: Males of many animals have more than a single exaggerated secondary sexual character, but inter-specific variability in the number of ornaments has never been explained. We examine three hypotheses that may account for the presence of multiple ornaments. First, the multiple message hypothesis proposes that each display reflects a single property of the overall quality of an animal. This is likely to be the case for ornaments that respond to condition on different time scales. Second, the redundant signal hypothesis suggests that each ornament gives a partial indication of condition. Females pay attention to several sex traits because in combination they provide a better estimate of general condition than does any single ornament. The redundant signal hypothesis predicts that (i) multiple ornaments should be particularly common among taxa with relatively uncostly and fine-tuned female choice, and (ii) females pay equal attention to the expression of all the secondary sex traits in order to obtain an estimate of overall male condition. Finally, the unreliable signal hypothesis argues that some ornaments are unreliable indicators of overall condition and are only maintained because they are relatively uncostly to produce and there is a weak female preference for them. This predicts that (i) multiple sexual ornaments should be particularly common in taxa with the most intense sexual selection (i.e. lekking and other polygynous taxa), and (ii) there should be more evidence for condition dependence in ornaments of species with single as opposed to multiple ornaments. Both the latter predictions are supported by data on feather ornaments in birds.

Human biochemical genetics

Abstract: So far in this course we have dealt entirely with the evolution of characters that are controlled by simple Mendelian inheritance at a single locus. There are notes on the course website about gametic disequilibrium and how allele frequencies change at two loci simultaneously, but we didn’t discuss them. In every example we’ve considered we’ve imagined that we could understand something about evolution by examining the evolution of a single gene. That’s the domain of classical population genetics. For the next few weeks we’re going to be exploring a field that’s actually older than classical population genetics, although the approach we’ll be taking to it involves the use of population genetic machinery. If you know a little about the history of evolutionary biology, you may know that after the rediscovery of Mendel’s work in 1900 there was a heated debate between the “biometricians” (e.g., Galton and Pearson) and the “Mendelians” (e.g., de Vries, Correns, Bateson, and Morgan). Biometricians asserted that the really important variation in evolution didn’t follow Mendelian rules. Height, weight, skin color, and similar traits seemed to

Saturation in qualitative research: exploring its conceptualization and operationalization

Abstract: Saturation has attained widespread acceptance as a methodological principle in qualitative research. It is commonly taken to indicate that, on the basis of the data that have been collected or analysed hitherto, further data collection and/or analysis are unnecessary. However, there appears to be uncertainty as to how saturation should be conceptualized, and inconsistencies in its use. In this paper, we look to clarify the nature, purposes and uses of saturation, and in doing so add to theoretical debate on the role of saturation across different methodologies. We identify four distinct approaches to saturation, which differ in terms of the extent to which an inductive or a deductive logic is adopted, and the relative emphasis on data collection, data analysis, and theorizing. We explore the purposes saturation might serve in relation to these different approaches, and the implications for how and when saturation will be sought. In examining these issues, we highlight the uncertain logic underlying saturation—as essentially a predictive statement about the unobserved based on the observed, a judgement that, we argue, results in equivocation, and may in part explain the confusion surrounding its use. We conclude that saturation should be operationalized in a way that is consistent with the research question(s), and the theoretical position and analytic framework adopted, but also that there should be some limit to its scope, so as not to risk saturation losing its coherence and potency if its conceptualization and uses are stretched too widely.
