That's addressed in the article, though - that there's no actual splicing in of sampled DNA fragments, but rather editing modern samples with the differences identified from examining ancient samples, and specifically quoting some guy who says "this may be a difference without distinction." Like, if you take the model file for a Superman tabletop miniature and replace the hair and shield logo with Bizarro's before 3D printing it, is it not then a Bizarro mini? (disregarding color, since that's a matter of painting it either way for resin printed minis)
