I'm guessing that what you mean is all those dubious skulls that the anti-evolutionaries can't agree on the classification of are different species of extinct ape. Firstly you have to realise that is *not* what those with some knowledge on the anti-evolution side are saying; its just something that you are clutching at, right? So that's 5 distinct species (just in that article) closer to human than any modern non-human that you are speculating have gone extinct. (and no fossil record of where modern humans or apes were at that time, curious that). At what point would you give up on that belief? If 10 were found? 15? 20? 50? 100? How perfect do you need the graduated fossil record to be before you start questioning anti-evolution? The fossil record is getting better all the time... Best not rest your faith on no further intermediate finds.
Something that you need to understand is that the fossil record has hardly any modern forms, and the deeper you go down the geological column the less the organisms you find resemble modern forms (deeper = more distant past). Does that fact suggest anything to you? It suggested a lot to many christian biologists, geologists, and paleontologists of the early 19th Century. Darwin just put together into a coherent whole what a lot of scientists were already seeing parts of; and most importantly he put forward natural selection as the driving force. It is not a coincidence that during the voyage of the Beagle Darwin was having the volumes of Lyell's geology works shipped out to him.
I dont care if you had a perfectly preserved "ape-man" i wouldn't believe evolution. I could explain it away as a genetic defect. You have your beliefs and I have mine. In the end when your before the lord you can explain yourself.
