Going from a product of selective breeding to a product of genetic engineering is a pretty big rewrite.
Yeah, like... anyone... noticed that.
Indeed. Not to mention that "selective breeding" and "genetic engineering" are not incompatible.
Of all the forms of continuity tailgunning, "but TWOK did it too" is so very often the wrongest and lamest. (Closely matched by the equally silly "you're just like the crazy fans who hated TWOK!!!")
