SpletTrade-offs are thought to be ubiquitous, come in different types, and have been at the heart of evolutionary biology, especially life-history theory. Whether phenotypic or genetic, whether based on trait pairs or on a large number of traits or genes, the intuitive understanding of trade-offs might have often been too simplistic.
