I'm afraid to have to tell you, pete, that this stuff is way beyond you. Popular science mags and snippets for news bulletins demand gross over-simplification. Those percentage figures are not what you will hear evolutionary scientists talking to each other about. And I'm sorry to disappoint you, pete, but whether it's "99%" or "85%" doesn't make a smidgeon of difference to the fact that the two species are evolutionarily linked. Anyway, you should, as good scientists always do, delight in the fact that new evidence can come to light to keep the debate fresh. Here, stop bothering us with yer creationist claptrap, embrace the truth for a change and get yer teeth into this: http://en.wikipedia.org/wiki/Human_evolutionary_genetics
