Mice with human brains?
Hmmm...
Were they purpose bred to be republican congresscritters?
This X-ray shows that mice have spines, so they would not be good substitutes for the typical Republican congressman.
Once the precedent is set for mixing human DNA with mice, does anybody here doubt that some researcher will mix human DNA with an ape?
Something to ponder: is an ape with 10% human DNA legally and morally to be considered an ape or a human with human rights? How about an ape with 90% human DNA? 99%?
If you took an ape egg cell, inserted 100% human DNA, implanted the egg cell in an ape and the resulting infant is born. Is that infant legally a human or an ape?
Do not assume that the above will not happen.
