Is there any fossil evidence to support the leap of one species to another? In fact is there any fossil evidence of any species, over any period of time, becoming another species?

Yes (though species never "leap" into another species). If you've been on these threads for any amount of time, you would have seen repeated postings detailing in excrutiating detail evolution from fish to birds (or something along those lines). It's been done a million times, yet creationist keep asking the same old tired questions.

I've been on here for several years. Your assertion that there is fossil records of fish evolving into birds is pure fabrication.
There has been much speculation that the similarities in bone structure or composition may indicate that some fish evolved into birds. The operative word is speculation. No body of evidence exists that can point to any clear example of evolution.
The doctrine of evolution is conjecture based upon a theory with massive gaps in the constructed reasoning.
