Hi there. I know what ethics are. In fact i spend a good deal of time here trying to teach them to the sociopaths that frequent this site.
Do you understand the science being done here? While the title makes a nice, sensational buzz - aided by people on the thread drawing positions from
science fiction books - the fact of the matter is that this is really nothing at all special.
Do you know what happens when you put the DNA that builds a mouse's eye into a fruit fly? It grows an eye - a fruit fly eye. Not a mouse eye. It has
a fragment of mouse DNA in there, but it's still a fruit fly. No ears, no tail, nothing like that.
This is because a cell is a cell. There are some chemical differences between various forms of life (and structural differences between Kingdom, of
course) but if you patch human cells into a mouse blastocyst, you're not getting Ratman, you're getting a mouse who has a clump of cells with human
DNA but that function as normal mouse cells.
Even if you take a sample of developmental cells, and transfewr them between embryos, you're going to get a result that is normal for the recipient;
for instance, if you take the cells of a limb bud from a chicken embryi and graft it onto a giraffe embryo, you're not going to get a wing - it's
going to make a leg just like a giraffe's. it responds to the chemistry and the DNA cues of hte nearby cells.
As for ethics, there's nothing more or less ethical about this research than there is qith smushing a cockroach - in fact smushing hte roach is, if
ethical, as it is an independent, living being.
