Abstract: Over the past 50 years, a generally accepted theory about the evolution of aging has been developed. One common conclusion that has been deduced from this theory is that aging is inevitable in organisms in which there is a difference between offspring and parents. A recent paper by Sozou and Seymour questions this prediction using a mathematical model, but it remains to be seen whether their new results stand up to more general analysis.
