Has there been any evidence showing major evolutionary change?

Evolution is all about constant change, whether gradual or in leaps. Consider a cloud in the sky: it is constantly changing shape due to natural forces. It might look like, say, a rabbit now, and a few minutes later appear to be, say, a horse. In between, the whole m is shifting about. In a few more minutes it may look like a bird. The problem for evolution is that we never see the shifting between shapes in the fossil record. All fossils are of complete animals and plants, not works in progress "under construction". That is why we can give each distinct plant or animal a name. If evolution's continuous morphing were really going on, every fossil would show change underway throughout the creature, with parts in various stages of completion. For every successful change there should be many more that lead to nothing. The whole process is random trial and error, without direction. So every plant and animal, living or fossil, should be covered inside and out with useless grow
