How did Penguin “evolve” or did they?

According to  Wikipedia “The evolutionary history of penguins is well-researched and represents a showcase of evolutionary bio geography; though as penguin bones of any one species vary much in size and few good specimens are known, the alpha taxonomy of many prehistoric forms still leaves much to be desired. Some seminal articles about penguin prehistory have been published since 2005;[15][20][23][24] the evolution of the living genera can be considered resolved by now…..Really?  So how did a bird learn how to swim?

Should a small penguins swim  dive at 6 to 12 km ?  How is that possible? While most of us probably swim at 2-3 MPH… but didn’t  a spurt stud or..that Mike Phelps’ fastest swimming speed could be six mph?  This number comes from a 2010 ESPN blog post on the subject of athlete speed. The ESPN post cites a 2008 blog post …but who cares…. The National Aquarium post says top-swimming athletes can average 5.25 mph, with the authors rounding up to six mph for Phelps.    But what about that funny looking bird?   There are reports of some penguins going at  velocities of 27 km/h (17 mph) …. The small penguins do not usually dive deep…   Larger penguins can dive deep  and fast. Dives of the large emperor penguin have been recorded reaching a depth of 565 m (1,854 ft) for up to 22 minutes.  But do suppose I will evolve in swimming that fast?  The really amazing speed of the Male emperor Penguin is not in water, but in walking around, without FOOD for almost 4 months, caring an egg on  THEIR FOOT!  TRY THAT DIET!  They say that TIME cures the broken heart…But what love Penguin must have?
