To be fair, Professor Church was quoted in two interviews: one in which he is all gung ho about the possibility of cloning a Neanderthal, and another in which he says he was misquoted about being ebullient over the possibility of cloning a Neanderthal, and then proceeds to be ebullient over the possibility of cloning a Neanderthal, only not at this exact moment. Got that? good.
Now what, you may ask, are the benefits to humanity that we should pursue this course of action? Church lists several possibilities, each one qualified with "mights" and "may be" and "possible that". He suspects that resurrecting their genome will create greater genetic diversity amongst humans (so now we would have to mate with Neanderthals) possibly preventing future plagues. On the other hand, other scientists point out that Neanderthals have not been exposed to modern diseases, so maybe not so much.
Then there is this peculiar possibility:
