Nevermind...you're not open to hearing the truth. Should have known better than to answer a clown :)

Evolution happens quite slowly, over a tremendous amount of generations, so the group which was changing/adapting/evolving itself away from the original genetics would continue to mate with unevolving members as well as evolving ones.
When a large enough group evolves genetically in the same direction at the same time, only then is the gene pool wide enough to support the continued growth of that "new" species, and will after enough generations have passed, cease to mate with the original species and only with their own genetic group.
Most of the time, the group will often not be large enough to sustain itself or change the DNA, or a group will be so small that they will not be able to perpetuate the new group, or will inbreed itself into sterility, birth defects, and extinction.
I also heard it might be RELATIVE LUNAR HUMIDITY

During meiosis, there is an event called crossing over between two chromsomes before they replicate. These chromosomes exchange genetic material between each other by breaking in places called linkage points and reattaching to the other chromosome. This is what allows for greater genetic variety, which can cause a new species.

The randomness of sexual reproduction produces genetic diversity. New species emerge when the environmental changes naturally select new survival characteristics.

genetic diversity is what causes a new species to emerge.

What do you mean? It evolves that way by process of natural selection.
Basically mutations occur from damaged DNA and if those abnormalities are beneficial to the species they will be more likely to survive and procreate, thus the "normal" species is replaced with the mutated one.

Mutations, and evolution.
New species don't just appear one day out of the blue. They evolve, slowly.

Is this a good time to ask about "Intelligent Design"?

Where does whynotaskdon get this stuff?
