There is also the Theory of Evolution which is the explanation of the how, why, where, and when of the facts of Evolution. The Theory of Evolution is still being debated and refined… by no means is it complete and perhaps it never will be… such is the nature of the fossil record.
I always find it amusing when people claim that they believe in "micro-evolution" but not "macro-evolution" for they seem to ignore a rather simple piece of logical reasoning; "A series of small changes carried on for a long time add up to a large change."
For instance: if you dug a small chunk of earth out of a large hill and place it in a pond the hill would still be a hill and the pond would still be a pond. However, if you and 1000 friends did this same activity every day for a few weeks you would find that soon there hill and the pond were gone. Continue the activity for longer and soon there would be a pond (or at least a hole) where the hill was and a hill where the pond was. Accepting that both "small changes over time add up to large changes" and "micro-evolution" are true; one is forced to find a biological mechanism that would prevent, reverse, or limit these changes to prevent a categorical shift such as one species evolving into another species. There is no such mechanism. "Macro-evolution" therefore is simply the logical result of "micro-evolution" over time.
1) Give examples of evolutionary transitions in which one species changes into another.

2) Specify the mechanism by which one species could change into another.
Genetic mutations happening over long periods of time. (Please see above.)
3) Specify the actual course of evolution in the past.
Which specific forms gave rise to which specific new forms?
Sorry, this hasn't been discovered and is not required. The best we can accomplish is which groups are related and something of the degree they are related, based upon homology of fossils and genealogy of living groups.
Another thing that is often ignored by those who do not believe evolution is the striking fact that the theory of evolution was developed before DNA was discovered or genetics was understood. In fact, the theory of evolution predicted that there must be a system by which such changes must take place… Evolutional Theory has a tremendous success rate. The prediction of what type of fossils we should find and where we should find them in the geologic column has been proven correct again and again.
