Analyses of ovarian activity reveal repeated evolution of post-reproductive lifespans in toothed whales
In most species the reproductive system ages at the same rate as somatic tissue and individuals continue reproducing until death. However, females of three species – humans, killer whales and short-finned pilot whales – have been shown to display a markedly increased rate of reproductive senescence...
