Or, the other species hetero-cialis....
if it really was homo-cialis, then extinction would not occur. this species probably took viagra, but then it took more than 8 hours to find a mate. if they took cialis, then they would have had 36 hours to find a mate, a much greater possibility that the species would have survived.
i wonder if they got medical attention after 4 hours?
