The Great Auk, while not directly related to Penguins, it does outwardly resemble them.  And, as a flightless bird in the Northern Hemisphere, it would have been exposed to many predators. 

One should also note that many penguins spend a significant portion of their lives on other southern continents other than Antarctica, again exposed to predators. 

Using wings as flippers while swimming sounds like a good explanation for penguin wings.  I wonder if after several million years, there will be a branch of the penguinn family that will evolve to be 100% aqueous, somewhat like the dolphins and

Birds fly to escape but they also fly to find stuff like food or nesting materials. There doesn't seem like there is a lot to look for in Antartica when most of the food is the ocean. Are there very many species of birds in the polar regions?

The list of Antarctic Birds is more diverse than I had realized.  The penguins get far too much attention.

Arctic birds may be quite different due to a difference in land distribution between the Arctic and Antarctic with the Arctic supporting a vibrant ecosystem during the summer.
