Study reveals extended lifespan in menopausal whale species

In an intriguing parallel to human biology, females of whale species which experience menopause have evolved extended lifespans, enabling them to support their offspring for longer, according to research by the University of Exeter, the University of York and the Centre for Whale Research.

The study focused on five whale species known to experience menopause. Menopausal female whales tend to live about 40 years longer than males of the same species, giving them extra years to care for their young and grandchildren.
