Because if 'evolution reacts' (q) then it would react by removing hymen. Also because women without torn hymen don't pass genes.

Did evolution reacted by removing tusks?

PS if you start to tell me how a hymen could be untorn even in the case of a complete vaginal intercourse I would slap you over TCP/IP.

Why would it? Women without torn hymen don't pass genes because they didn't have sex, not because they possessed a hymen. As soon as they have sex, the hymen tears - so it poses no barrier to passing on genes.
