Didn’t the Russians try something like this back in the 1930s with Gorillas an attempt to make a super soldier. Or is that just a myth.
I remember such experiments being reported on way back in 1968. One tabloid back then had a fake photo of a man in a suit with a lizard’s head. The title was...LADIES, WILL YOUR NEXT HUSBAND LOOK LIKE THIS?
From my reading, such mixing of genetics always caused the fetus to self abort, or be born sterile.
