It doesnt take test tubes and scientists with microscopes to make genetic manipulations, sometimes fallen angels manipulate genetics with simple means.@Brad Huber -- the fact Is that there Are babies born with Both and / or no genitalia. It Is rare. But it Does happen.
As far as genetic codes are concerned. Maybe you've been watching sci-fi -- researchers like to play around at times. But in real life -- there are in-born processes in the human body that take care Of genetic code problems. But people born with such anomilies can't reproduce. A lot die at an early age. And, yes, I've done a bit of studying in that area.
Evolutionists claim that mutations over time will produce a 'new' being. But it takes millions of years -- which no one can verify Anyway.
