A more modern take on evolution would suggest that sharks, such as the great white are constantly evolving, but perhaps they are so highly adapted to the task in hand that they are constantly brought back in line. Evolution being a serious of microjumps in the direction dictated by current pressures. Sadly they are unlikely to evolve fast enough to deal with the stupid chinese soup thing...

@crackrjack - feathers are a beautiful example of evolution, evidence suggests they evolved for insulation first and then were adapted to flight. In which case why would a mammal ever evolve along that route? Especially when a flap of skin had already evolved in the common ancester of modern bats?

Subushie: Your belief that seals fins are becoming legs is, evolutionary theory speaking, backwards.
Evolution theorizes that land mammals became aquatic and legs turned back into fins, which explains dolphins, whales, seals, otters, etc...
Why there aren't any flying mammals with feathers, or hairy reptiles by now, are interesting questions. Another interesting question is why haven`t horseshoe crabs, nautili, and sharks have barely changed, if at all, for over a hundred million years.
