Yes.
What do you mean by "fossil dispersion"? Strategraphic dispersion or geographical dispersion or temporal dispersion?
Yes -- the question of whether all the bones belong together.
It says a lot about our understanding of the morphology of the species in question and the competency of the scientist involved. It says nothing about the basic concepts here.
It does when the basic concepts are confirmed or denied by spurious fossil combinations.
Even people like me who believe in evolution, do not disbelieve in Divine Creation.
My point is seldom communicated effectively, but here goes: Creation is not a theory, it is faith. I disagree with those who want to come up with a scientific basis for creation, because the creation of the bible is a supernatural event. Science is a way of observing the natural, it cannot be used to observe the supernatural. You can't draw scientific conclusions about the supernatural.
Whether evolution is a sound, viable theory does not contradict the creation story of how man and the universe came into being. Evolution can be completely correct from the standpoint of how things work, and exactly wrong from the standpoint of what really happened.
And I simply cannot find evolution to be scientifically sound. Its adherents spend far too much time attacking creation and not nearly enough time addressing the shortcomings of evolution.
