Or to put it another way, if there was originally a Patient Zero primate, and he/she mutated with a beneficial trait, over the course of many generations it would seem that the beneficial trait would eventually dominate the species because the evolved primate had all of the advantages of regular primates PLUS the mutation - sort of like upgrading the trim level on a car

When two groups of the same species spread out, they may become geographically isolated from one another. The first population may continue to live without really changing over time. However, the other population may need to undergo a series of adaptations to survive.

If the two populations become reproductively isolated from one another, over many generations the two groups can form two distinct species. When the populations become isolated, there is no longer gene flow which prevents any new traits from being shared.

Speciation in animals appears to happen on a geological time scale, and hence why many people have trouble coming to terms with it.

This is called allopatric speciation

To put it another way, most traits are not purely beneficial or detrimental Ina vacuum. Flatter teeth are better for chewing vegetables, while sharper teeth are better for cutting through meat. A geographically isolated primate population which has a different (meat heavier) diet could adapt toward sharper teeth, while a population that subsists on vegetable adapts toward flatter teeth.

If the geographic locations were reversed each beneficial trait would become detrimental. Hence the two environments drive the two populations further apart, causing speciation.

Well, sexuality is like Down Syndrome in that it's at least to some extent probably determined by your chromosomes, but DS is far more straightforward. You can trace DS to one chromosome, but not all traits are like that.

It's likely that multiple genes contribute, as well as genetic modifications, and environmental factors. Scientists will probably never find a "gay gene" just as they will never find a "fat gene". But that doesn't mean that genes don't play a role.

Primates were evolving but now do not. Or did you find some new ones somewhere out there?

It takes hundreds/thousands/millions of generations before new traits generally become widely manifest, and for speciation to take place, assuming a change of environment or some other factor in which adaptability would prove beneficial. In the past 150 years that Evolution as an idea has been around a primate specific speciation event has not been observed because it is an incredibly small time frame on an Evolutionary scale. Does not mean evolution is somehow debunked. Additionally, there is likely not going to be a single, naturally occurring at least, birth where you can pin-pointedly say this offspring is a different species from it's parents.

In other species though evolution has been observable, i.e. wheat plants, some studies done on butterflies, etc.

Edit: It always amazes me when this topic is brought up how many people either did not take a biology class or just dismissed all the evidence put in front of them because "the bible says...".

I do not debunk the fact that species can evolve or change as such. I just do not grasp one species changing into another. Because one species has similar items of anatomy does not mean necessarily that they are some how related or have common ancestry.
