I didn't ask "or hunt much more rarely than males."   Regardless, you can't name any mammal that eats meat where females don't also hunt, and so we've gotten past your fantasy about early female mammals stuck in burrows nursing pups millions of years ago while only the males go out to hunt.

That brings us to 30,000 years ago.  The cave paintings in Europe show what are basically human stick figures that could be either men or women or both.  Apparently you think they look like men because you think that women didn't hunt.
