Planet of the Apes?

A new study has found a link between modern language and primitive sign-language used by chimpanzee's and bonobos. It points to the use of a specific sign that is used when a male asks for help in a fight and is also used when asking for food that has been stolen. These same gestures used in different contexts allows for the hypothesis that they are not random. The question I pose is whether evolution from apes specifically is believed by all readers, why or why not?

My own opinion as those of you that join us in IR are aware is that of course we have. Most obvious is that of our genetic makeup. We are a mere chromosome away, during meiosis of course, from matching those of the chimpanzees. The loss of this chromosome has been speculated to have been formed when a fusion occured between two of their chromosomes, forming a more human looking ape. Though gradual progression, each new step making them more and more human like we evolved over a period of thousands of years.
