Scientific Arguments

Abstract Our words shape our thinking, our thinking creates action. Scientific terms can be particularly influential when used in everyday language in terms of allegedly scientific arguments that back certain views or actions. Such use can be especially toxic when the terms refer to concepts that are ill-defined, outdated or questionable themselves. The term “good genes” represents an exemplary case in this regard. It refers to the belief system of eugenics and implies a moral perspective. The latest political debates demonstrate how easily such terms and concepts are employed to induce racist thinking and action; in the end it may even result in specific medication, selective investment in medical treatment, and so ultimately impacting the life and death of patients. Science has the obligation to explicitly opt-out from such lines of argument, and to routinely check and re-think its theories, concepts and vocabulary.

Fitness Benefits

Sexual selection theory predicts that females should choose males that signal viability and quality. However, few studies have found fitness benefits among females mating with highly ornamented males. Here, we use Arctic charr ( Salvelinus alpinus ), a teleost fish with no parental care, to investigate whether females could gain fitness benefits by mating with highly ornamented and large-sized males. Carotenoid-based coloration signalled by males during spawning is believed to be an indicator of good genes for this species. Paternal effects on offspring size (body length and dry body mass) were examined experimentally by crossing eggs and sperm in vitro from 12 females and 24 males in a split-brood design and raising larvae to 30 days past hatching. We clearly demonstrated that there was a relationship between offspring size and paternal coloration. However, a negative interaction between paternal length and coloration was evident for offspring length, indicating that positive effects of paternal coloration were only present for smaller males. Thus, the red spawning coloration of the male Arctic charr seems to be an indicator of good genes, but the effect of paternal coloration on offspring length, an indicator of ‘offspring quality’, is size dependent.

A catalyst meeting on sexual selection studies was held in July 2013 at the facilities of the National Evolutionary Synthesis Center (NESCent) in Durham, NC. This article by a subcommittee of the participants foregrounds some of the topics discussed at the meeting. Topics mentioned here include the relevance of heritability estimates to assessing the presence of sexual selection, whether sexual selection is distinct from natural selection, and the utility of distinguishing sexual selection from fecundity selection. A possible definition of sexual selection is offered based on a distinction between sexual selection as a frequency-dependent process and fecundity selection as a density-dependent process. Another topic highlighted is a deep disagreement among participants in the reality of good-genes, sexy-sons, and run-away processes. Finally, the status of conflict in political-economic theory is contrasted with the status accorded to conflict in evolutionary behavioral theory, and the professional responsibility of sexual-selection workers to consider the ethical dimension of their research is underscored.
