Genetic change within a population is not the same as one species becoming a different species.

Oh. So we can go about changing your DNA all day long and you'll still be you?

Most likely I'll still be human. But if you can change my DNA and turn me into a newt, I'd be impressed.

If we could change DNA wouldn't we be able to cure certain genetically "caused" (predisposed) diseases immediately? That would be a pretty slick deal, like a "Search and Replace" function in word processing.

While we have made great advances in genetics and DNA, I doubt we will ever see the ability to change all the DNA molecules in animals or humans to the "improved" engineered version. Perhaps we may be able to change a DNA strand in a zygote and pass the improvements onto the next generation, but not beyond that.
