Wouldn't that, as you said, be like " trying to cross a cat with a dog?"
That's exactly what it is, and I think it's creepy.
BTW, we use heirloom seeds in our garden. I don't want our great grand children coming out with fins (or laying eggs or something).
My point was that if Monsanto can cross plant DNA with animal DNA, why would you think that ‘human’(modern man) DNA cannot be crossed with Neanderthal DNA?
YOU have Neanderthal DNA, pretty much everyone does. Except for one specific group. Care to guess which group?
