Tecoyah,
I know what evolution is and explained it previously. You can get different breeds but not different species. Let me tell you, giraffes had normal necks and they ate from the grass and the trees, but then the grass came hard to be found as the animals reproduced. The Giraffes with short necks died because they can’t reach tall trees to eat. The tall ones ate and reproduced.
Giraffe with tall neck + Giraffe with normal or tall neck have higher probability of giving birth to a giraffe with a tall neck. Hence evolution takes place this method.
That’s the maximum what evolution can do. A dog cannot grow a fin because he can swim better across the river because on the other side there is food. Let’s examine:

Question #1) Was it indeed....a Giraffe before the length in neck changed?
Question #2) What of this:
Whale Evolution:
"Call it an unfinished story, but with a plot that's a grabber. It's the tale of an ancient land mammal making its way back to the sea, becoming the forerunner of today's whales. In doing so, it lost its legs, and all of its vital systems became adapted to a marine existence -- the reverse of what happened millions of years previously, when the first animals crawled out of the sea onto land.
Some details remain fuzzy and under investigation. But we know for certain that this back-to-the-water evolution did occur, thanks to a profusion of intermediate fossils that have been uncovered over the past two decades."

The debate on evolution is somewhat heated, and in my opinion needlessly so. Once a basic understanding of the theory is understood, much of the dissagreement no longer exists, I would recommend you spend a few minutes reading up on current theory surrounding the evidence for adaptation.
