2. I know a lot of Creationists like to throw around the improbability of Evolution.

Are you talking about abiogenesis, the rise of the first life, or evolution, the way in which life changed over time?

3. Are there fossil records of overlap, lower forms and higher forms existing together.

Umm, look around. Your own intestinal tract is covered in lower life forms called bacteria. Some of our early chordate ancestors are still alive, such as the tunicates (ie sea squirts). We don't need to look at the fossil record to know that lower and upper lifeforms lived at the same time.

4. Why don't we have tails?

As noted above, the great apes (which includes us) do not have tails. The tail was already gone when we split off from the chimp line.

However, some of us do, although it is a rare occurence. It is called an atavism, a relic of our evolutionary past: ABE (C1, 2, and 3 refer to caudal vertebrae, in laymen terms "bones of the tail")

Other example of this phenomena are whales that sprout legs with hooves.

So can we give a rough estimate to the improbability of evolution?

If you have limited resources and an imperfect replicator, the chances of evolution occuring are 1 in 1.
