|MadSci Network: Evolution|
I understand how the first organisms came about and that they reproduced asexually. How then could sexual reproduction arise when asexual reproduction is so efficient, less complex, and requires much less organization and energy? The only reason I can think of is because sexual reproduction allows for more varience and therefore better adaption to the environment but even this answer doesn't fully explain the evolution behind the concept. Why would organisms ever desire to exchange genetic material? I realize this is a difficult question but please try to help me understand.
