Did Sex Become Fun?

The BBC had a headline saying sex invented in slimy Scottish Lake. I've got the male sexual organ. We've got barbs lots of barbs to keep everything in place and to grab onto things. From the female point of view what's going on? Well this was the other big discovery Dallas with microbrachias because it was the very first time in evolution we'd found sexual dimorphism where males and females actually differed with different sexual organs. So yeah first time ever we have the female sexual reproductive organs preserved in in a vertebrate backbone animal.
