Nearly all birds use their wings for flight, but penguins use their as paddles for swimming. They spend most of their lives in the sea and find their food there.
Although many birds can both swim and fly, no other bird can swim as well as the flightless penguins.
Penguins have muscles, bones and organs very much like those of flying birds, so we assume that their ancestors must have been able to fly. Probably they slowly lost the power of flight while learning to swim faster and dive deeper in search of food. This must have happened millions of years ago, for by Miocene times - 25,000,000 years ago - there were penguins very much like those alive today.

because they don't fly long distances, only short ones (saw em at the zoo last week.)
they walk a lot. Or waddle.

They work like propellers in helping them to negotiate the waters.

its in the environment. those guys taught that instead of flying they rather swin and stay in water since there are more food in the sea. and also blame mutation.

It's because they can't fly, and it so that they can swim better as well

Because that's all they need. They don't need them to fly, so why have them bigger?
