Abstract

The authors outline research strategies that may identify the possible adaptive value of a trait. But this does not solve the problem of how to decide which characteristics of living organisms require an adaptive explanation. I suggest that knowledge of the ontogenetic and phylogenetic construction of a trait facilitates the identification of features that may have been acted on by natural selection.
