Why has evolution created gender?
I mean, back when it was just a bunch of cells, they would divide to reproduce.
Why did evolution suddenly deny that factor and create males and females.
The sperm fertilizes the egg which will later become another male or female to repeat the process. But why not just have it so everyone has both sperm and eggs.
I really don't see a reason for different lovees.
Is it so that reproduction can be planned or something, because it requires two different mammals to complete?
Is it so that natural selection had a better chance to continue through the rejection of mates with less desirable traits?
I don't get it.
