Apparently. The numbers didn't work out.

It's mentioned in LMG. There's plenty of stuff out there for yr google
engine, e.g.:

< But a new study finds no evidence for this "grandmother hypothesis."
Reporting in the April 23 issue
of the journal Nature, three researchers suggest that menopause carries no
evolutionary benefit or
cost. Menopause, they say, is simply a consequence of aging, and how long
females live after
menopause depends upon how long a species needs to raise last-born infants
to the age of
independence. >
