Telomere-based replicative senescence is thought to function as a potent mechanism of tumor protection in humans. Whether this mechanism is conserved in other species is still unclear. In this review we present an inter-species critical overview of some of the available literature on the fundamental biology of telomeres and telomerase during development, regeneration, cancer and aging of living organisms during their evolutionary journey through time.
