Susanne Huber and Martin Fieder from the Department of Evolutionary Anthropology compared 48 mammal species such as mice, rabbits, sheep, marsupials, wolves, lions, polar bears, monkeys, elephants, humans, manatees and whales. While animals with a short lifespan were usually fertile to the end of their lives, the long-lived representatives often ended their productive phase before the end of their lifetime, they report.
