Can you fuse 2 pair of chromosomes from a human and produce an ape, with completely different genes, chromosomal makeup, and architecture? No. If they were the same, genetically, there might be some credence for a chromosome fusion theory. Merely counting chromosome pairs does not make an ape into a man, or vice versa.
A sable antelope has 23 chromosome pairs.. did it come from the ape, too?
A potato has 24 pairs. Did man descend from a potato?
..and i don't mean the potato headed posters on this forum, who blindly follow their beliefs, claiming 'Science!', but are clueless about scientific methodology.
