However, there is another reason which is evolutionarily important, which is as follows: there is more genetic variation in organisms that reproduce sexually. This is evolutionarily important because it is genetic variation ( mutation) which drives the process of natural selection. This is turn leads to evolution.

I have a gene or several genes, which allow me to drink sea water and then expel the excess salt without offsetting the tonicity of my cells. I would be able to survive and reproduce during a drought when no fresh water or very little is necessary. When I reproduce that trait will get passed on to some of my offspring, they will then be able to survive and reproduce. This particular trait has been selected for in this particular environment. Eventually, a new species of iguana will emerge. Where did this ...
