Im sorry fugawi, I think you are probably genuinly trying to do your best but I'm not quite sure why you keep using the language normally resigned to christian anti-evolution propaganda. For example missing link. What does missing link even mean? What do you mean by this? We can measure the similarity of any two species very easily. Secondly chromasomes are readily rearanged in evolutionary time. If you take the 20 pairs of chromasomes of a mouse and the 23 of a human you will find that none of them match up, but bits of all the human chromasomes will have matches to different spots in the mice chromasomes because the chromasomes have re-arranged. This bit just isnt true. Chimps and gorillas both have 24 chromasomes, and humans have 23. However chimps and humans are more closely related than chimps and gorillas so, probably what happened is somewhere in the human linneage after we split from chimps, our ancestors lost a pair of chromasomes, probably by incorporating it into the other 23 sets of chromasomes that we had. "apes" do not have different ancestors to humans. Each linneage has some ancestors that are specific to their own evolution and then going back further each species has ancestors that it shares with other apes.
