Is grandparenthood an unusual feature of human lifespan?

“Evolutionary perspectives on the post-reproductive years have highlighted grandparenthood as an unusual feature of the human lifespan that is only shared with one or two other species, such as some whale species,” says David A. Coall of Edith Cowan University, who co wrote the article along with Ralph Hertwig of the University of Basel.
