Okay, forgive me if this is a stupid question...but it has been on my mind all day.
I mean, why is there even two different genders to begin with? Where did sexual reproduction arise in evolutionary history? I tried looking this up, but I found nothing more than the fuction of sexual reproduction, and certain advantages.
I am aware that sexual reproduction is useful because it provides genetic diversity, but at what point did it come into play?
Have a read of this thread at RDF http://forum.richarddawkins.net/viewtop ... 7#p2692507 (http://forum.richarddawkins.net/viewtopic.php?p=2692507#p2692507) it should give you some pointers.
There's a species of snake somwhere, that has
three genders.

Definitely NOT picturing tri-sexual scalies...
Okay, maybe I was, but I have a very visual mindset and it's not my fault.
Ugh. Scalies.
