The forming of a fossil is a very rare situation (that needs rare circumstances). We should be lucky we found as many fossils as we did and do. And all fossils found, back the evolution theory up. Thousands and thousands of fossils.
There are many scientific articles about the evolution of the human eye (since creationist always use that as the evidence evolution cannot be true). It is all backed up with excellent evidence and a clear logic.
Gradual evolutionism does not need it's magic unicorn. It needs research and evidence. And there is plenty. Like I said before...evolution is a fact. There are still processes that we don't understand (yet), but so far all found evidence does back this 'theory' up. I am not talking about a book of evidence. I am talking about library's full of books all over the world with only evidence.
