How will creationists react to the first human-chimp hybrid?

Hi, I'm new to this forum and to evolution also, I'm not creationist nor evolutionist I'm still reading and gaining more knowledge.I was discussing evolution with one of my friends when he asked me the following question: Why evolution didn't produce species with sophisticated brain (similar or more intelligent) such as human kind ? human beings are the only species that have a very sophisticated brain is it a coincidence ?I would be grateful if you give me the scientific answer for this question.

Thank you RAZD and bluegenes for your answers, I find the idea of evolution attracting and plausible every time I introduced to one of its facts, evolution has a lot of evidence support it. on the other hand when I read something written by creationists or watch a documentary about the evidence of young universe and young earth I find it convincing also, they have scientific facts support their claim, so every time I try to investigate I get lost.I don't want to be biased to one side, I'm searching for the truth.

Thanks RAZDI was reading about Neanderthals, it is amazing subject and it may be one of the most powerful evidence of evolution. but, I have a question about Neanderthals genome, latest researches says that Neanderthals and Homo Sapiens share more than 99% of genes, some creationists claim that Neanderthals are humans with deformed skeleton or the adaptation makes them look like as they are.My question is: do you think the fact that we share more than 99% of our genes with Neanderthals supports creationists claim ?---------------------------------------------------------------------
I feel sorry sometimes that people easily take outstanding scientific achievements and add it to the credit of religion and say that God told them about that thousands of years .... unethical !!!!!!!
