But *can* we create a wooly mammoth?
I strongly suspect that you cannot create a proper wooly mammoth without a female mammoth to grow it in, or without the gut flora it gets from its peers and all th rest of it. Then there's learned behaviour from the herd and you can carry on. I suspect all you'd have would be an artificial organism that had a vague resemblance to a mammoth. No matter what the children's pictures of Dawkinsianity might present, there seems to be an awful lot more to inheritance than just the DNA.
