Sexual v asexual reproduction shows design more-so than evolution. Evolution could have found a better way to allow for more anti-bodies and viral resistance than to make 2 different sets of organs, separate hormone levels, etc.
This seems ass backwards to me. It seems like design would use the better way (if indeed there is one), while evolution, not having a goal in mind, is stuck with whatever shows up variationwise. Where did you get the idea that evolution should result in the "better" way to accomplish any particular physiologic task?
