Why does sex exist?

[Lemur]

I linked to the most current research on the subject, don't really know why it's being ignored.

Y'all should get on your knees and thank ringworms and malaria plasmodia for spanky sextime. 'Cause it sure looks like the energy and population division brought about by sex simply would not be worth it if it weren't for the hangers-on.

[Pannonian]

I hate to break it to you, but that research was too gross to merit consideration, regardless of its factual basis.

This is the greatest and most valid anti-scientific argument ever.

That is not an explanation for sex as we, humans, know it. That's an explanation for sexual reproduction (pollen, flowers, etc.), but not "spanky sextime". The explanation for "spanky sextime" is efficiency: it's vastly more efficient to inseminate directly than leave things to chance...
