Darwin hypothesized that some animals, when selecting sexual partners, possess a genuine “sense of beauty” that cannot be accounted for by the logic of natural selection. This hypothesis has been notoriously controversial. In this chapter I propose that the concept of agency can be useful to operationalize the “sense of beauty”, and can help identify the conditions under which one can infer that animals are acting as (aesthetic) agents. Focusing on a case study of the behavior of the Pavo cristatus, (...) I identify the types of evidence that would allow for the inference of agency through aesthetic choice. (shrink)

Claims that our species is an “evolutionary success” typically do not feature prominently in academic articles. However, they do seem to be a recurring trope in science popularization. Why do we seem to be attracted to viewing human evolution through the lense of “success”? In this chapter we discuss how evolutionary success has both causal-descriptive and ethical-normative components, and how its ethical status is ambiguous, with possible hints of anthropocentrism. We also place the concept of “success” in a wider context (...) of biological thought, contrasting it with two other value-laden concepts: evolutionary progress and human uniqueness. Claiming the human species to be an evolutionary success is ostensibly grounded in metrics such as the dominance or the size of the human population, but often goes beyond this, suggesting that humans are a unique species or the pinnacle of evolutionary progress.
