Fossils are historical references to organisms long dead. Using these snapshots in time, one can look for trends to see if changes in groups of organisms truly occur on large timescales. In my example, a fossil with no likenesses to a lineage either above or below that could be considered a challenge to evolution, unless tampering cannot be ruled out (see Nebraska Man, and Piltdown Man).
So tell me, why do you consider this pig such immutable evidence? It was not subject to any evnironmental selection pressures like all other non genetically engineered animals on the planet. It is obvious to most of us (but not to you it appears), that because of this, it only proves that man can indeed genetically engineer plants and animals, which is not very astounding. So while it may have been intelligently designed, it doesn't offer any proof that intelligent design might have occurred in the past, which is where evolution explains the origins of life.
And a living specimen rules out that consideration, how?
What about the future? Does Evolution predict such speciation events, or is Intelligent Design more valid?
