Then what exactly are you arguing? Chromosomal fusion occurred, the evidence for that is overwhelming (2 centromeres, a telomere in the middle.)
And you're saying this doesn't support common ancestry of apes and chimps, but don't explain why. When we sequenced chimp and human genomes, we noticed we had a fewer pair of chromosomes than they did, this would be a problem for common descent, since an organism simply can't lose a pair of chromosomes. This means the only way common descent could be valid is if we found 2 fused chromosomes in the human genome that matched the pair we were missing. And we did, human chromosome number 2. How exactly does this not support common ancestry?
What it does more is demonstrate how common ancestry is supported; that is that human and chimp DNA is so similar. We find very similar sequences in the same locations all over the genomes (I named ALUs as well as ERVs earlier for a more definitive example.) This not need be the case. If God made chimps and humans separately, he set everything up in such a way that we appear to share a common ancestor.
How do you know that chromosome 2 in humans has the same function as the said corresponding chromosomes in apes? We don't. For all we know the function of chromosome 2 could affect organ makeup in humans, and the 2 chromosomes in apes could affect height limitations in apes. Now imagine if said chromosomes in apes differed in function depending on the species. This clearly wouldn't prove common ancestry.
Now both of us agree that this single fusion could not have caused such drastic changes alone. So obviously the fusion alone could not suggest common ancestry. However, you say that said fusion event was a catalyst. Well then where are the other processes that led to a human from an ape after the fusion event?
