I knew about orca females enjoying a post-reproductive lifespan (ie going through menopause), but in recent years the number of non-human mammalian species doing this has grown to five, and all of them are toothed whales, which is intriguing. So I took a new paper on the evolution of this trait in whales as an occasion to write about the menopause of whales an women. (I recently had Of elephants and men, so I'd better give poor old John Steinbeck a rest now.)
The feature is out now:
