- Observations
In the wild, 10 year-old females have been known to give birth and record longevity is 13.7 years [0434]. One wild born male was around 20.6 years old when he died in captivity [0671]. Gene expression levels are associated with age, whereas other examined factors such as disease, sex and social status have minimal effects. Features of senescence such as immunosenescence and metabolic ageing are evolutionary conserved between wolves and humans [1188].
