摘要: Recent comparative studies have suggested that cooperative breeding is associated with increases in maximum lifespan among mammals, replicating a pattern also seen birds and insects. In this study, we re-examine the case for increased mammalian breeders by analysing large dataset of longevity records. We did not find any consistent, strong evidence longer lifespans than other mammals after having controlled variation body mass, mode life data quality. The only possible exception to general trend found African mole-rats (the Bathyergid family), where all members are relatively long-lived, but social, cooperatively species appear be much longer-lived solitary species. However, mole-rat rarely been kept captivity or followed longitudinally wild so it seems likely their has underestimated when compared highly researched social Although few subterranean received attention captive setting, current instead supports causal role living on extension mammals.
