Some species, however, enjoy sustenance: mortality and fertility remain constant. Here we develop simple but general evolutionary-demographic models to explain the conditions that favor senescence vs. sustenance. The models illustrate how mathematical demography can deepen understanding of the evolution of aging.}, URL = {https://www.demographic-research.org/volumes/vol23/23/}, eprint = {https://www.demographic-research.org/volumes/vol23/23/23-23.pdf} }
