I was able to easily refute the OP as apes don't have it. Also, we found that...
abu afak did not explain ape fusion of its two chromosomes and human chromosome 2 fusion correctly. Next, he just discarded his opposition's argument because he's way too stupid to refute it. Facts are facts.
The evidence shows this isn't even true, so there isn't a common ancestor. However, no atheist is going to admit that. It's why I keep saying there are two types of science today. If creation science was taught in schools, then the general public would have a choice of which science is not biased and true.
