Thats true of English as well.
The masculine, wermann/wereman/wehr/vir/wer was dropped in favour of just using the gender-neutral man for both around the move from old to middle english, so while man usually means male now, the original gender neutral meaning is retained, as for example in mankind or your fellow men, man the lifeboats, etc.
It's really only from the 1960s on that man has become primarily used to mean males only and even then not universally.
Aha, haven't thought of that.
