here is what i don't get. If there is no god how do you explain these two things?
How did an a sexual reproducing organism evolve into 2 sexes? How did a 3 chamber heart evolve into a 4 chamber heart?

The fourth chamber proved to be better for survival and thus better for reproductive purposes. |

Genders is a good way to get genetic diversity which again makes the organisms more adaptive. There are animal species that only have one known sex - f.ex there are some fish hybrids, at least one or two species of reptiles and many stick insect species seem to get by just fine without males. What you have then are obviously females that produce clones. These species are generally viewed as more vulnerable because of a lack of genetic diversity.
Genders are not the same in different species, it doesn't always mean XX or XY chromosomes. In honey bees, the male is a haploid "clone" of the queen which basically means that the queen just lays an egg containing a male and that male has only one set of every chromosome so he has only half as much genetic material as his diploid mother and sisters. Offspring as a result of mating between a haploid male and the diploid queen will result in diploid female offspring.

If you try to grasp what's going on, you might see that Darkest Hour posted the argument that genders can't be explained without a God .. but it can. Like so many other things, evolutionary theory explains how it evolved from natural selection.
Some time ago, creationists were pushing the idea of irreducable complexity saying that certain things could not have evolved because until they were "finished", they would serve no function. Their arguments have since been refuted by biologists and, more than anything else, only really served to showcase creationists' typical lack of understanding of evolutionary theory and their tendency to "prove" their own theories only by pathetic pseudo-scientific attempts at disproving others.

A good guideline is that if a site looks like it might be made by creationists, never ever believe anything they say without thoroughly checking sources first. They are deliberately spreading misinformation in order to manipulate you.
